Dear Fellow Investors,

     The past six months have been a buoyant period for the general market, and
for Internet stocks in particular. We are pleased to report that our Fund
returned a very solid 15.57% for the six-month period ended 2/28/07, handily
outperforming both the Nasdaq and the broader S&P 500 index, which returned
11.03% and 8.93%, respectively.

     Our distinctive strategy of maintaining a balance between growth stocks and
value stocks within the Internet space has continued to serve us well. The
growth component of our portfolio, which includes some innovative Chinese
Internet companies, has enabled us to share in the overall market upswing.
Meanwhile, the value component--which helps limit our risk by affording extra
diversification and some downside protection--did not hinder us. While many of
our peers eschew "Internet value," we note that in this period fully half of our
top ten performers were value holdings.

     Some of our favorite value picks are in business software, an area in which
the ongoing transition toward open-source and software-as-a-service applications
has caused upheaval, spurring consolidation among the smaller players. This in
turn has fueled something of an acquisition frenzy among the dominant players,
such as IBM and Oracle. We recently increased our exposure in this area, in
light of our belief that the Linux market will continue to grow as a percentage
of total IT spending. In the fall, we purchased shares of Red Hat when this
formerly expensive growth stock fell on the news that Oracle would offer a
competing product. We also built a position in Novell, the second largest player
in Linux. With close to $1 billion in both net cash and sales, Novell's
valuation was especially alluring to us as a classic value situation with future
growth potential. We plan to further increase our exposure to this attractive
space in the near future.

     Another of our top value holdings is InfoSpace, the Internet search and
portal company that has been undergoing extensive restructuring. Last September,
the stock stumbled on news that the company would lay off a large number of
employees. Noting that the company has a strong balance sheet, which includes no
debt and about $400 million in cash, we took the opportunity to add
substantially to our position. We were pleased to enjoy a nearly 30% rise in the
stock price by the end of February.

     On the growth side of the equation, we remain bullish in the Chinese
Internet. Our top two performers in the Fund this period were CDC Corp., the
Chinese enterprise software, mobile application and online game provider, and
Tencent Holdings, the dominant player in instant messaging. Both CDC Corp. and
Tencent rose over 60% during this period. China has the second highest number of
Internet users in the world, and the online advertising market there is
experiencing stellar growth--much stronger than here in the U.S. Extensive
investment in anticipation of the Olympic games in Beijing will further boost
near-term growth in the Chinese economy.

     Stateside, we continue to believe in the Internet advertising market, and
some of our Fund's largest positions are in industry leaders including Google,
Yahoo and CNET.

     Looking forward, our general approach to managing the fund remains
consistent: We continue to believe that having a mix of growth- and value-
oriented holdings is the best way to achieve strong returns while minimizing
volatility. We remain committed to diligently managing our positions, and taking
any potential



profits in a timely manner. Our ability to move freely between companies of
different market capitalizations as well as invest in international markets
should help us take advantage of attractive investment opportunities wherever
they develop.

     Once again, we would like to take this opportunity to thank all of the
Fund's shareholders for their continued trust and confidence, and we look
forward to a bright future together.

JACOB INTERNET FUND
NOTES TO THE FINANCIAL STATEMENTS
FEBRUARY 28, 2007 (UNAUDITED)
- --------------------------------------------------------------------------------

NOTE 1--DESCRIPTION OF FUND

Jacob Internet Fund Inc. (the "Corporation"), was organized as a Maryland
corporation on July 13, 1999 and is registered under the Investment Company Act
of 1940, as amended (the "1940 Act"), as an open-end management investment
company issuing its shares in series. The Corporation currently consists of one
"diversified" series, the Jacob Internet Fund (the "Fund") and the authorized
capital stock of the Fund consists of twenty billion shares of stock having a
par value of one-tenth of one cent ($0.001) per share. The primary investment
objective of the Fund is long-term growth of capital with current income as a
secondary objective. The Fund commenced operations on December 14, 1999.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Fund.

     (a) Investment Valuation -- Investment securities traded on a national
     securities exchange are valued at their market value determined by their
     last sales price in the principal market in which these securities are
     normally traded (except those traded on the NASDAQ National Market and
     Capital Market exchanges which are valued at the NASDAQ Official Closing
     Price ("NOCP")), unless there are no transactions on the valuation date, in
     which case they are valued at the mean between the closing bid and ask
     prices. Securities traded over-the-counter are valued at the last reported
     sales price unless there is no reported sales price, in which case the mean
     between the closing bid and ask prices is used. Foreign securities,
     currencies and other assets denominated in foreign currencies are
     translated into U.S. dollars at the exchange rate of such currencies.
     Foreign equity securities are valued at the last sale price at the close of
     the exchange on which the security is principally traded. Debt securities
     with maturities of sixty days or less are valued at amortized cost, which
     approximates market value. Where market quotations are not readily
     available, are unreliable or whose values have been materially affected by
     events occurring before the close of U.S. markets but after the close of
     the securities' primary markets, securities are valued at fair value using
     procedures approved by the Board of Directors that are designed to
     determine a security's fair value.

     In September 2006, the Financial Accounting Standards Board ("FASB") issued
     a Statement of Financial Accounting Standards ("SFAS") No. 157, "Fair Value
     Measurements." SFAS No. 157 defines fair value, establishes a framework for
     measuring fair value in accordance with GAAP and expands disclosure about
     fair value measurements. SFAS No. 157 is effective for financial statements
     issued for fiscal years beginning after November 15, 2007. Management is
     currently evaluating the impact of the adoption of SFAS No. 157 on its
     financial statements.

     (b) Income Recognition--Interest income is accrued as earned. Dividend
     income is recorded on the ex-dividend date. All discounts and premiums are
     amortized using the effective interest method for tax and financial
     reporting purposes.

JACOB INTERNET FUND
NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)
FEBRUARY 28, 2007 (UNAUDITED)
- --------------------------------------------------------------------------------

     (c) Securities Transactions--Security transactions are accounted for on
     trade date. Realized gains and losses on securities sold are determined
     using specific identification.

     (d) Foreign Currency Transactions--The books and records are maintained in
     U.S. dollars. Foreign currency denominated transactions (i.e. market value
     of investment securities, assets and liabilities, purchases and sales of
     investment securities, and income and expenses) are translated into U.S.
     dollars at the current rate of exchange.

     The Fund does not isolate that portion of the results of operations
     resulting from changes in foreign exchange rates on investments from the
     fluctuations arising from changes in market prices of securities held. Such
     fluctuations are included with the net realized and unrealized gain or loss
     from investments.

     (e) Distributions to Shareholders--The Fund records distributions to
     shareholders on the ex-dividend date. Dividends from net investment income,
     if any, are declared and paid annually. Distributions of net realized
     capital gains, if any, will be declared and distributed at least annually.
     The amounts of distributions from net investment income and net realized
     capital gains are determined in accordance with federal income tax
     regulations, which may differ from those amounts determined under U.S.
     generally accepted accounting principles. These book/tax differences are
     either temporary or permanent in nature. To the extent these differences
     are permanent, reclassifications are made in the capital accounts in the
     period that the differences arise. The reclassifications have no effect on
     net assets or net asset value per share.

     (f) Federal Income Taxes--The Fund complies with provisions of the Internal
     Revenue Code applicable to regulated investment companies, including the
     distribution of substantially all of the Fund's taxable income.
     Accordingly, no provision for federal income taxes is considered necessary
     in the financial statements.

     (g) Use of Estimates--The preparation of financial statements in conformity
     with accounting principles generally accepted in the United States requires
     management to make estimates and assumptions that affect the reported
     amount of assets and liabilities at the date of the financial statements
     and the reported amounts of revenues and expenses during the reporting
     period. Actual results could differ from those estimates.

     (h) Repurchase Agreements--The Fund may enter into repurchase agreements
     with member banks of the Federal Reserve System and with broker-dealers who
     are recognized as primary dealers in U.S. government securities by the
     Federal Reserve Bank of New York. Repurchase agreements involve an
     agreement to purchase a security and to sell that security back to the
     original seller at an agreed-upon price and an agreed-upon time. Because
     the security purchased constitutes collateral for the repurchase
     obligation, a repurchase agreement may be considered a loan that is
     collateralized by the security purchased. Although the securities subject
     to the repurchase agreement might bear maturities exceeding one year,
     settlement for the repurchase would never be more than 397 days after the
     Fund's acquisition of the securities and normally would be within a shorter
     period of time. The resale price of the

                                       13



JACOB INTERNET FUND
NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)
FEBRUARY 28, 2007 (UNAUDITED)
- --------------------------------------------------------------------------------


     security back to the original seller will be in excess of the purchase
     price, reflecting an agreed upon market rate effective for the period of
     time the Fund's money will be invested in the security, and will not be
     related to the coupon rate of the purchased security. In the event that the
     repurchase agreement is held for more than one day, the security serving as
     collateral for the repurchase agreement will be marked-to-market daily to
     ensure that the value of the collateral does not decrease below the
     purchase price, plus accrued interest. If a decrease occurs, the seller
     will provide additional collateral to add to the account to maintain
     appropriate collateralization.

     The use of repurchase agreements involves certain risks. One risk is the
     seller's ability to pay the agreed upon repurchase price on the repurchase
     date. If the seller defaults, the Fund may incur costs in disposing of the
     collateral, which would reduced the amount realized thereon. If the seller
     seeks relief under the bankruptcy laws, the disposition of the collateral
     may be delayed or limited. Delays may result in possible decline in the
     value of the underlying security while the Fund seeks its rights thereto,
     possible lack of access to income on the underlying security during the
     delayed period, and expenses in enforcing the Fund's rights.

     (i) Uncertain Tax Positions--On July 13, 2006, FASB released FASB
     Interpretation No. 48 ("FIN 48") "Accounting for Uncertainty in Income
     Taxes". FIN 48 provides guidance for how uncertain tax positions should be
     recognized, measured, presented and disclosed in the financial statements.
     FIN 48 requires the evaluation of tax positions taken or expected to be
     taken in the course of preparing the Fund's tax returns to determine
     whether the tax positions are "more-likely-than-not" of being sustained by
     the applicable tax authority. Tax positions not deemed to meet the more-
     likely-than-not threshold would be recorded as a tax benefit or expense in
     the current year. Adoption of FIN 48 is as of the date of the last NAV
     calculation in the first required financial statement reporting period
     required for fiscal years beginning after December 15, 2006 and is to be
     applied to all open tax years as of the effective date. On December 22,
     2006, the SEC granted a six-month delay in the required implementation of
     FIN 48 for mutual funds. At this time, management is evaluating the
     implications of FIN 48, and the impact of this standard on the Fund's
     financial statements has not yet been determined.

At August 31, 2006, the Fund had an accumulated net realized capital loss
carryover of $140,669,840, of which $50,793,480 expires in 2009, and $89,876,360
expires in 2010. To the extent the Fund realizes future net capital gains,
taxable distributions to its shareholders will be offset by any unused capital
loss carryover. For the year ended August 31, 2006 the Fund utilized $12,808,000
in capital loss carryover. At August 31, 2006, the Fund had net realized losses
from transactions between November 1, 2005 and August 31, 2006 of $21,065, which
is deferred for tax purposes and will be recognized on September 1, 2006.

The Fund paid $1,145,833 out of ordinary income during the six months ended
February 28, 2007 and paid no distributions during the fiscal year ended August
31, 2006.

NOTE 5--INVESTMENT ADVISORY AND OTHER AGREEMENTS

The Corporation has an Investment Advisory Agreement (the "Advisory Agreement")
with Jacob Asset Management of New York LLC (the "Adviser"), with whom certain
officers and Directors of the Board are affiliated, to furnish investment
advisory services to the Fund. Under the terms of the Advisory Agreement, the
Corporation, on behalf of the Fund, compensates the Adviser for its management
services based on an annual rate of 1.25% of the Fund's average daily net
assets.

U.S. Bancorp Fund Services, LLC serves as transfer agent, administrator and
accounting services agent for the Fund. U.S. Bank, N.A. serves as custodian for
the Fund. U.S. Bancorp Asset Management serves as the securities lending agent.

NOTE 6--SECURITIES LENDING

The Fund may lend portfolio securities up to 33% of its total assets (including
such loans) to borrowers under terms of participation in a securities lending
program administered by U.S. Bancorp Asset Management. The

                                       16



JACOB INTERNET FUND
NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)

- --------------------------------------------------------------------------------


Agreement requires that loans are collateralized at all times in an amount equal
to at least 102% of the market value of any loaned securities at the time of the
loan, plus accrued interest.

The Fund receives compensation in the form of fees and earns interest on the
cash collateral. The amount of fees depends on a number of factors including the
types of security, length of the loan and credit standing of the borrower. The
Fund continues to receive interest or dividends on the securities loaned during
the borrowing period. The Fund has the right under the terms of the securities
lending agreement to recover the securities from the borrower on demand. U.S.
Bancorp Asset Management received $19,422 from the Fund for its securities
lending administrative services during the six months ended February 28, 2007.

As of February 28, 2007, the Fund had loaned securities that were collateralized
by cash equivalents. The cash collateral is invested by the custodian with the
approval of the Adviser. Although risk is mitigated by the collateral, the Fund
could experience a delay in recovering its securities and possible loss of
income or value if the borrower fails to return the borrowed securities. As of
February 28, 2007, the value of the Fund's securities on loan was $38,540,323
and the value of the related collateral was $41,063,021.

NOTE 7--DISTRIBUTION AND SERVICE PLAN

The Corporation, on behalf of the Fund, has adopted a distribution and service
plan (the "Plan"), pursuant to Rule 12b-1 under the 1940 Act. The Plan provides
that the Fund will compensate the Adviser up to 0.25% per annum of the Fund's
average daily net assets for certain expenses and costs incurred in connection
with providing shareholder servicing and maintaining shareholder accounts and to
compensate parties with which it has written agreements and whose clients own
shares of the Fund for providing servicing to their clients ("Shareholder
Servicing Fee"). Effective December 31, 2006, the Adviser has contractually
agreed to waive 0.10% of the Shareholder Servicing Fee through December 31,
2007. For the six months ended February 28, 2007, expenses of $46,389 were
waived by the Adviser. The Plan also provides for a distribution fee equal to
0.10% of the Fund's average daily net assets on an annual basis ("Asset Based
Sales Charge"). The fee is used to compensate Quasar Distributors, LLC, the
Fund's distributor (the "Distributor") for basic distribution services, out of
pocket expenses incurred in connection with activities to sell Fund shares,
advertising, compliance reviews, and licensing of the Adviser's staff. The
Distributor may make payments from time to time from the Asset Based Sales
Charge to broker-dealers and other financial professionals whose clients are
Fund shareholders for providing distribution assistance and promotional support
to the Fund. Remaining amounts of the Asset Based Sales Charge may be used to
satisfy distribution costs as directed by the Adviser. The Fund incurred
$162,361 in expenses pursuant to the 12b-1 Plan for the six months ended
February 28, 2007. At February 28, 2007, $43,484 of the Shareholder Servicing
Fee was available for eligible 12b-1 expenses.

JACOB INTERNET FUND
ADDITIONAL INFORMATION ON FUND EXPENSES
- --------------------------------------------------------------------------------

FOR THE SIX MONTHS ENDED FEBRUARY 28, 2007

As a shareholder of a mutual fund, you may incur two types of costs: (1)
transaction costs, including sales charges (loads) on purchase payments,
reinvested dividends, or other distributions; redemption fees; and exchange
fees; and (2) ongoing costs, including management fees; distribution and/or
service (12b-1) fees; and other fund expenses. The Fund does not currently
charge sales charges (loads) or exchange fees. The Fund assesses a redemption
fee of 2% on shares sold within 30 days following their purchase date. In
addition, you will be assessed fees for outgoing wire transfers, returned checks
and stop payment orders. The Fund charges management fees and distribution
and/or service (12b-1) fees. The Example reflects the 0.10% waiver of
distribution and/or service (12b-1) fees by the Adviser for the period from
9/1/06-2/28/07. The Expense Example is intended to help you understand your
ongoing costs (in dollars) of investing in the Fund and to compare these costs
with the ongoing costs of investing in other mutual funds. The Example is based
on an investment of $1,000 invested at the beginning of the period and held for
the entire period (9/1/06-2/28/07).

ACTUAL EXPENSES

The first line of the table below provides information about account values
based on actual returns and actual expenses. Although the Fund charges no sales
load, the Fund charges a redemption fee of 2% on shares sold within 30 days
following the purchase date. In addition, you will be assessed fees for outgoing
wire transfers, returned checks and stop payment orders at prevailing rates
charged by U.S. Bancorp Fund Services, LLC, the Fund's transfer agent. If you
request that a redemption be made by wire transfer, currently the Fund's
transfer agent charges a $15.00 fee. The Example does not reflect transactional
costs, such as redemption fees. You may use the information in the first line
below, together with the amount you invested, to estimate the expenses that you
paid over the period. Simply divide your account value by $1,000 (for example,
an $8,600 account value divided by $1,000 = 8.6), then multiply the result by
the number in the first line under the heading entitled "Expenses Paid During
the Period" to estimate the expenses you paid on your account during this
period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values based on a hypothetical return and hypothetical expenses based on
the Fund's actual expense ratio and an assumed rate of return of 5% per year
before expenses, which is not the Fund's actual return. The hypothetical account
values and expenses may not be used to estimate the actual ending account
balance or expenses you paid for the period. You may use this information to
compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds. Please note that the
expenses shown in the table are meant to highlight your ongoing costs only and
do not reflect transactional costs, such as redemption fees. Therefore, the
second line of the table is useful in comparing ongoing costs only, and will not
help you determine the relative total costs of owning different funds. In
addition, if the transactional costs were included, your costs would have been
higher.

APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT

At an in-person meeting held October 20, 2006, the Board, including each of the
independent Directors, approved the renewal of the Advisory Agreement. In
reaching this decision, the Board took into account a combination of factors,
including the nature and quality of services provided by the Adviser, the Fund's
performance, and Fund expenses. The Board did not identify any single factor as
all-important or controlling, and this summary does not detail all the matters
considered.

In evaluating the Fund's performance, the Board discussed the Fund's performance
relative to the peers to which the Fund had been comparing itself at each Board
meeting for the past several years. The independent Directors noted that in the
past three years, the Fund had consistently outperformed those peers. The Board
also discussed the longer-term performance of the Fund, noting that for the
five-year period ending September 30, 2006 the Fund had above average
performance relative to its Morningstar peers. The independent Directors
continued to note the adaptation of the Adviser's investment strategy with
changing market conditions in addition to the overall improvement of the
Adviser's investment process. The Board also considered the Adviser's quarterly
commentary at the Board meetings and intermittent updates, which confirmed a
disciplined application of the investment process and the Adviser's adherence to
the objectives of the Fund.

The independent Directors then reviewed and compared expenses of the Fund to
expenses within the Lipper category of Science and Technology Funds, as well as
to the expenses of the individual funds within the Fund's peer group. They noted
that while the Fund's investment advisory fee was somewhat higher than these
Lipper peers, the fee was reasonable relative to the Adviser's expertise in the
Internet sector and the Fund's performance compared to other funds within the
Internet sector. The independent Directors also reviewed and considered
information presented at the meeting regarding the total expense ratio of the
Fund relative to peer mutual funds. They noted that the Fund's expenses were
within a reasonable range and that the total expense ratio for the Fund declined
over the last fiscal year and was now in the third quartile. The Board next
discussed inherent advantages of some of the peers that were part of large fund
families and the economies of scale that were afforded to those funds.

The Board also reviewed the Adviser's profitability, including gross fees paid
to the Adviser for investment advisory services to the Fund and profit
participation of the Adviser's partners. Based on the Adviser's profitability,
the Board accepted that the Adviser was not experiencing economies of scale at
the Fund's current asset levels. The Board and the Adviser discussed the
Adviser's financial statements. The Board considered the Adviser's contractual
waiver of ten basis points of the Shareholder Servicing Fee to reduce
shareholder expenses. The Board also discussed the possibility of fee
breakpoints and the Adviser was agreeable to fee breakpoints if economies of
scale were achieved.

The Board reviewed and considered the nature and quality of the services
provided to the Fund. The Board noted that they believed that the investment
team was experienced and capable of producing above average investment returns.
They also noted that they believed that the investment team was one of the most-
experienced with respect to the Internet sector and that the Fund and its
shareholders had benefited from the attention and expertise of these
individuals. The independent Directors also considered the other services to

the Fund provided by the Adviser including the compliance functions through the
Chief Compliance Officer and the oversight of the Fund's service providers. They
also noted that the Adviser performs much of the marketing functions for the
Fund and shareholder service.

In considering such material, the independent Board members received assistance
and advice from and met separately with independent counsel. Based upon its
review of such material and information together with such other information as
it deemed relevant, the Board, including a majority of independent Directors,
concluded that the fee payable under the Advisory Agreement was reasonable and
that continuance of the Advisory Agreement was appropriate and in the best
interest of Fund shareholders.
