Dear Mr. Carney:

       We have reviewed your revised filing and have the following comments. In
some of our

understand your
disclosure.

       Please respond to these comments within ten business days by providing
the requested
information or advise us as soon as possible when you will respond. If you do
not believe our
comments apply to your facts and circumstances, please tell us why in your
response.

Revised Preliminary Proxy Statement on Schedule 14A

Summary of the Proxy Statement
Parties to the Business Combination, page 15

1.    We note the diagrams that you provide in response to prior comment 6.
Please enhance
      your disclosure regarding the structure of Successor following the
business combination
      by disclosing the anticipated percentage of the outstanding common stock
of Successor
      owned by each of the depicted stockholders assuming no redemptions and
maximum
      redemptions allowed under the merger agreement. Also, provide a
cross-reference to the
      risk factors on pages 44 and 45 discussing the risks posed by the
significant percentage of
      outstanding voting power held by the Sponsor and existing Grid Dynamics
stockholders,
      as well as the operation of the Stockholders' Agreement, following the
business
      combination.

2.       We note from your response to prior comment 9 that Grid Dynamics'
contracts are mostly
         short-term time and materials contracts and that you do not
systematically track a backlog
         metric in managing the business. Please tell us the range or average
contract term for Grid
         Dynamics contracts and your estimate of backlog as of December 31,
2018.

3.       We note your revised disclosure in response to prior comment 23. The
added disclosure
         regarding the range of net income as a percentage of revenues is not
on a comparable
         basis to your disclosure, which indicates that Adjusted EBITDA is
improving. Please
         revise to discuss the fluctuations or trends in net income during
these periods or discuss
         the fluctuations in Adjusted EBITDA as a percentage of revenues in
lieu of your current
         disclosures. In addition, your discussion of GAAP net income should
precede the
         disclosures regarding Adjusted EBITDA. Refer to Question 102.10 of the
Non-GAAP
         Compliance and Disclosure Interpretations.

Exclusive Forum, page 199

4.       The revised disclosure that you provide here in response to prior
comment 27 refers to a
         state or federal court located within the State of Delaware as the
exclusive forum, whereas
         the risk factor that you provide on page 52 in response to such
comment refers to the
         Court of Chancery of the State of Delaware as the exclusive forum.
Please revise to
         reconcile the disclosure.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.
