                                                        what the sponsor and
its affiliates have at risk that depends on the completion of a
                                                        business combination.
Include the current value of the securities held, loans extended,

and may be incentivized to complete an acquisition of a less

company or on terms less favorable to shareholders rather than liquidate.

3.       We note the statement that    The PIPE Investors have agreed to
purchase either (i)
         8,200,000 shares of New Tempo common stock or (ii) $25.0 million of
ACE   s 12.0%
         convertible senior notes due 2025, for an aggregate of $107,000,000 of
gross proceeds, in
         the PIPE Investment.    Please reconcile with the definition on page 6
that    PIPE
         Investment    is (a) the purchase of up to 8,200,000 shares of New
Tempo common stock
         pursuant to the PIPE Common Stock Subscription Agreements and (b) the
Convertible
         Note Investment.    (Emphases added.) If the PIPE Investors purchase
either $82.0 million
         in common stock or $25 million in notes, please explain how this would
lead to aggregate
         gross proceeds of $107 million.
4.       We note that certain shareholders agreed to waive their redemption
rights. Please describe
         any consideration provided in exchange for this agreement.
Summary of the Proxy Statement/Prospectus, page 29

5.       We note your use of industry and market data throughout the prospectus
derived from
         studies or reports from third parties, including IPC International.
Please revise to include
         the names and dates of those studies, and to the extent you
commissioned any of the third
         party data you cited, provide the consent of the third party in
accordance with Rule 436.

6.       Please clarify if the sponsor and its affiliates can earn a positive
rate of return on
         their investment, even if other SPAC shareholders experience a
negative rate of return in
         the post-business combination company.
7.       You note that the Proposed Certificate of Incorporation is silent as
to the issue of the
         application of the doctrine of corporate opportunity. Please address
this potential conflict
         of interest and whether it impacted your search for an acquisition
target.
Comparative Per Share Information, page 52

8.       It is not clear to us why the pro forma basic and diluted net loss per
share amounts
         presented on page 53 do not agree to the amounts presented on pages
193-194. Please
         clarify or revise.
9.       It is not clear why ACE   s historical weighted average shares
outstanding and net loss per
         share as of and for the year ended December 31, 2020 do not agree to
the amounts
         presented in ACE   s annual financial statements. Please clarify or
revise.
10.      It appears that underwriting fees remain constant and are not adjusted

redemption levels.

         dilution adjustment based on the company's additional financing
activities. To the extent
         they will, quantify the number and value of securities the sponsor
will receive. In
         addition, disclose the ownership percentages in the company before and
after the
         additional financing to highlight the dilution risk to public
stockholders.
12.      Disclose the material risks to unaffiliated investors presented by
taking the company
         public through a merger rather than an underwritten offering. These
risks could include
         the absence of due diligence conducted by an underwriter that would be
subject to liability
         for any material misstatements or omissions in a registration
statement.
13.      Please revise the conflicts of interest discussion so that it
highlights all material interests
         in the transaction held by the sponsor and the company's officers and
directors. This
         could include fiduciary or contractual obligations to other entities
as well as any interest
         in, or affiliation with, the target company. In addition, please
clarify how the board
         considered those conflicts in negotiating and recommending the
business combination.
14.      Please clarify in the risk factor on page 57 whether Tempo has been
materially impacted
         by recent supply chain issues, such as those affecting the
semiconductor industry. If so,
         please provide relevant detail including any material risks or impact
to your results of
         operations or management   s ability to forecast. In this regard, we
note your disclosure on
         page 61 that due to the COVID-19 pandemic, Tempo has experienced some
supply
         constraints, including with respect to semiconductor components.
Business Combination Proposal
Registration Rights Agreement, page 120

15.      We note that the merger agreement contemplates the entrance into an
amended and
         restated registration rights agreement pursuant to which New Tempo
will agree to register
         for resale certain shares of New Tempo common stock and other equity
securities of New
         Tempo that are held by the parties thereto from time to time. Please
disclose whether
         there are, or whether you expect, any maximum cash penalties under the
registration rights
         agreement(s), if applicable. Please also disclose any additional
penalties resulting from
         delays in registering your common stock. Refer to ASC 825-20-50-1.
Projected Financial Information, page 138

16.      Please expand to fully describe the material assumptions underlying
the projections
         contained in the first and second bullet points on page 140. Provide
further explanation to
         support a revenue compound annual growth rate of 23% between 2021 and
2025.

20.      You disclose on page 236 that sales and marketing expenses decreased
for the year ended
         December 31, 2020 compared to the year ended December 31, 2019
partially due to an
         average reduction of 22% in headcount as a result of the global
pandemic; however, you
         disclose that general and administrative expenses increased partially
due to an average
         growth of 33% in headcount beginning end of fiscal year 2019 through
fiscal year 2020.
         Please revise your disclosure to clarify how you experienced both an
increase and a
         decrease in headcount in 2020 as compared to 2019.
