better
understand your disclosure.

       Please respond to this letter by amending your registration statement
and providing the
requested information. If you do not believe our comments apply to your facts

Registration Statement on Form S-4

Unaudited Pro Forma Condensed Combined Financial Information, page 147

1.     Please tell us how you considered all the provisions of ASC
805-10-55-12.a through e and
       805-10-55-13 in determining that Thunder Bridge will be considered the
accounting
       acquirer in the merger transaction. Specifically address the fact that
following the merger,
       senior management will be comprised entirely of Repay's management; five
of the nine
       board seats will be held by Repay's current directors, and Corsair will
hold a 27% interest
       in the combined entity.
2.     Your pro forma financial statements as presented assume no Class A
ordinary shares were
       redeemed. However, we note that you may be required to account for the
Repay
       acquisition as a reverse merger, if more than 5,516,968 Class A ordinary
shares are

         redeemed such that there will be insufficient cash on hand to satisfy
the cash consideration
         condition. Notwithstanding your response to the previous comment,
please include
         additional pro forma information that assumes various redemption
levels and include a
         presentation that gives effect to the reverse merger accounting, or
explain why you believe
         such information need not be presented. Refer to Rule 11-02(b)(8) of
Regulation S-X.

3.       Please revise note (e) to include the assumptions used to determine
the pro forma
         adjustments related to the Tax Receivable Agreement. Tell us whether
you assumed the
         tax impact related to the exchange of Post-Merger Repay Units for
Class A common
         stock. If so, disclose the number of units assumed to be exchanged for
purposes of your
         pro forma calculations and how you determined that such assumption met
the factually
         supportable criteria of Rule 11-02(b)(6) of Regulation S-X.

related to the new
         debt that will be issued at the closing of the business combination.
Please revise to clarify
         how this adjustment is impacted by the repayment of Repay's
outstanding debt and
         include the calculations and assumptions that support this adjustment.
Similar revisions
         should be made to explain the calculations used in note (aa).

comparable companies the
         board considered in determining Repay's fair market value.

6.       You refer to year-over-year payment volume growth of 42% in fiscal
2018. Tell us what
         percentage of such growth was attributable to the Paymaxx and
PaidSuite acquisitions.
         To the extent your acquisitions have significantly contributed to your
period-over-period
         growth in volume and revenue, please revise to indicate as such.
Similar revisions should
         be made to the Overview section of your MD&A.
