       Please respond to this letter by providing the requested information and

statement on
EDGAR. If you do not believe our comments apply to your facts and circumstances
or do not
believe an amendment is appropriate, please tell us why in your response.

      After reviewing the information you provide in response to these comments

Draft Registration Statement on Form S-1 furnished December 18, 2019

Prospectus Cover Page, page 1

1.     The name of your company on the registration statement cover page is
Merritt Topco,
       Inc., but you identify yourself as Datto on the prospectus cover page.
Please clarify
       whether it is your intention to rename Merritt Topco, Inc. prior to the
close of your initial
       public offering. Further, please provide consistent definitions for the
term "Datto" and
       clarify in the summary how you will refer to your operating subsidiary
Datto, Inc. to
       distinguish it from the public parent entity.
2.     On your cover page or summary, please highlight that Vista Equity
Partners and its
       affiliates ("Vista") will have the right to nominate all but one of the
directors of the
       company.

Prospectus Summary, page 1

3.       Please disclose the percentage of annual recurring revenue ("ARR")
generated from the
         700 MSP partners that accounted for more than $100,000 ARR for each
period presented.
Risk Factors
We are an "emerging growth company" and we expect to elect to comply with
reduced public
company reporting requirements...., page 52

4.       You state that you have elected to take advantage of the extended
transition period for
         complying with new or revised accounting standards and, therefore,
will not be subject to
         the same new or revised accounting standards as other public companies
that comply with
         such new or revised accounting standards on a non-delayed basis.
Please revise to further
         clarify that as a result of such election, your financial statements
may not be comparable
         to companies that comply with public company effective dates.
Provisions of our corporate governance documents could make an acquisition of
us more
difficult ...., page 53

5.       Please consider providing a separate risk factor that discusses the
risks associated with
         your business combination provision that will contain similar
protections as Section 203
         of the Delaware General Corporations Law. We note it appears that only
the Board may
         be required to approve interested transactions under this provision.
Please discuss how
         this provision would apply to interested transactions involving Vista
and portfolio
         companies in its affiliated funds. For example, employees or members
of affiliates of
         Vista are members of your board and Vista currently has nomination
rights for all but one
         of your directors. Also, please discuss the resulting conflict of
interests of any transaction
         involving Vista and how this provision expires in 3 years.
A significant amount of our total outstanding shares are restricted from
immediate resale ....,
page 56

6.       Please expand this risk factor to clarify that in addition to the fact
that future resales of
         your shares may depress the market price for your shares, you may have
difficulty raising
         additional capital. Further, clarify that you have a registration
rights agreement with
         Vista, and that if Vista resells a significant amount of its shares
pursuant to this agreement
         you will not receive the proceeds from those offerings.
Use of Proceeds, page 62

7.     We note that you plan on using a portion of the proceeds from this
offering to repay
FirstName LastNameTim Weller
       outstanding borrowings under your term loan facility. We also note that

Management's Discussion and Analysis of Financial Condition and Results of
Operations
Overview, page 70

8.       We note your discussion throughout your prospectus of the numerous
risks that Brexit
         poses to the company's financial condition and results of operations.
Please expand this
         discussion to disclose what steps, if any, management is preparing to
take to mitigate and
         manage the risks posed to the company's business if a "hard" Brexit
occurs (e.g. no
         agreements on data migration between the U.K. and the European Union).
Key Performance Metrics, page 74

9.       You state that your contracts typically begin with a 1-year or 3-year
term and auto-renew
         on a monthly or annual basis thereafter. Please tell us whether your
ARR calculations
         include the annualized value of monthly contracts, and if so, explain
your basis for
         annualizing revenue from such customers. In your response, please
provide us with
         cancellation/attrition rates or, alternatively, renewal rates for your
monthly subscribers
         and tell us the amount of revenue recognized from monthly subscriber
for each period
         presented. Also, revise your disclosures related to the ARR
calculations to address the
         inclusion of monthly subscriptions, to the extent material.
10.      The pricing of your subscription services appears to be dependent upon
SMB user seats,
         MSP seats, or endpoints. Please provide a description of these terms
and advise us
         whether they would be considered key performance indicators.
Business, page 89

11.      Please include a discussion regarding the development and description
of each of the
         company and its primary operating subsidiaries, Merritt HoldCo, Inc.
and Datto, Inc.
         Also, describe further the transactions between Vista and both Datto,
Inc. and Autotask
         Superior Holding, Inc. that formed the basis of your operating
company. Include a
         description of the consideration transferred and clarify whether these
transactions included
         any related party interests. Refer to Item 101(a)(1) of Regulation
S-K.
Our Market Opportunity, page 96

12.      Please provide a more detailed discussion of how Frost & Sullivan
estimated your
         addressable market to be approximately $28 billion in 2019. Include
any material
         assumptions Frost & Sullivan made and provide a more detailed
explanation of their
         methodology. Further, given that 77% of your revenues are generated in
the United
         States, please clarify, if known, how much of your addressable market
was based on
         foreign markets and/or markets in which you currently do not have
operations.
Our Products, page 97

13.      We note that you derive approximately $50.5 million in revenue from
devices in both your
         Unified Continuity and Networking Solutions. Please provide a clearer
description of
 Tim Weller
FirstName LastNameTim Weller
Merritt Topco, Inc.
Comapany NameMerritt Topco, Inc.
January 14, 2020

FirstName LastName
         what products within each solution comprise device revenue, and
whether
         devices constitute a material amount of revenue in each category. For
example, it is
         unclear whether Networking Solutions are mostly device sales, and what
percentage of
         Unified Continuity revenues are from devices.
14.      Please clarify how you obtain your devices. You reference the use of
manufacturing
         partners, but it is unclear whether you are designing proprietary
devices that are protected
         through patents and made through the use of contract manufacturers.
The risk factor on
         page 24 mentions the use of manufacturing partners, but does not
indicate whether your
         third party manufactured devices are off-the-shelf existing products
or are significantly
         different from products offered to MSPs by other vendors.
15.      Please consider disclosing the revenue for Unified Continuity,
Networking, and Business
         Management Solutions. It is unclear how significant each product
category is to your
         business.
16.      Please explain further the termination provisions included in the MSP
partner agreements.
         In this regard, on page 21 you state that such agreements may be
terminated for any
         reason by either party with advance notice prior to each annual or
monthly renewal date.
         For example, clarify whether an MSP partner can terminate their annual
subscription in
         the middle of the subscription term or whether termination can only be
effective upon the
         renewal date. If the former is the case, state whether the MSP is
subject to penalties if
         they terminate before the end of the contract term.
Marketing and Sales, page 103

17.      Please clarify whether your sales teams operate across your different
solutions. For
         example, it is not clear whether each MSP is assigned separate sales
representatives for
         each solution category, or if they are assigned a single sales team or
representative that
         provides sales for all of your solutions.
Description of Certain Indebtedness, page 124

18.      You describe that your business plan includes strategic acquisitions
to supplement the
         offerings provided in your platform. The negative covenants described
on page 125 and
         in the risk factor on pages 48-49 include making investments, merging,
incurring
         contingent obligations and other items. Please clarify the exceptions
to these negative
         covenants and whether the negative covenants will significantly
restrict your ability to
         proceed with an acquisition strategy, or require a waiver from your
lender.
Description of Capital Stock, page 127

19.      In this section, you describe certain anti-takeover provisions, such
as shareholder action
         by written consent, the ability to call a special meeting, advanced
notice provisions,
         removal of directors, and supermajority voting provisions that will
change if Vista reduces
         its beneficial ownership below varying percentages. Please clarify
here and in the related

FirstName LastNameTim Weller
Merritt Topco, Inc.
Comapany NameMerritt Topco, Inc.
January 14, 2020

Page 5
FirstName LastName
         risk factors that the changes in your corporate governance documents
as Vista reduces its
         beneficial ownership below the respective thresholds will increase the
anti-takeover effect
         of these provisions. Further, clarify the mechanics of how these
changes will be
         implemented, such as whether they will be effective immediately after
Vista files its
         beneficial ownership reports showing it holdings are below the
relevant thresholds, or
         whether it requires further action by the board or otherwise. Also,
please clarify how you
         will notify public investors as to changes in your corporate
governance due to changes in
         beneficial ownership of Vista and its affiliates falling below these
ownership thresholds.
Underwriting, page 141

20.      Please identify your underwriters in your next amendment. Further, on
page 145, please
         describe if your lead underwriters have provided you any material
services beyond their
         underwriting activities pursuant to your underwriting agreement, such
as providing
         financing.
21.      Please clarify the "certain exceptions" to the 180-day lock up
agreement and whether
         these exceptions apply to all parties to the agreement.
Notes to Consolidated Financial Statements
Note 7. Goodwill and Intangible Assets, net, page F-22

22.      Considering the apparent magnitude of goodwill recognized in the Datto
acquisition,
         please explain to us the terms of this transaction and provide us with
the acquisition-date
         fair value of the total consideration transferred. Tell us the factors
that make up the
         goodwill recognized, such as the specific synergies you identified,
the relative magnitude
         of each synergy, the intangible assets that did not qualify for
separate recognition, or other
         factors considered. Also, when performing the purchase price
allocation for this
         acquisition, explain further how you determined the fair value of the
other intangible
         assets acquired. Similar information should be provided as it relates
to the Autotask
         transaction, to the extent material.
23.      Please tell us how you determined the useful lives of your technology
and customer
         relationship intangible assets, citing the relevant accounting
guidance outlined in ASC
         350-30-35-1 through 35-5.
18. Subsequent Events
Stock Options Grants, page F-34

24.      Please provide us with a breakdown of all options granted in fiscal
2019 and to date in
         fiscal 2020, and include the fair value of the underlying common stock
at the date of such
         grants as determined by your board of directors. To the extent there
were any significant
         fluctuations in the fair value prices from period-to-period, describe
for us the factors that
         contributed to these fluctuations, including any intervening events
within the company or
         changes in your valuation assumptions or methodology, underlying
common stock used to
         value such awards as determined by your board of directors.
