set forth in its letter, dated July 25, 2023, relating to the Company’s Registration Statement on Form F-4 filed via EDGAR
on June 26, 2023.

The Company is concurrently
filing via EDGAR Amendment No. 1 to the Form F-4 (the “Amendment No. 1”), which reflects the Company’s

Registration Statement on Form F-4 filed June 23, 2023

Risk Factors

“Failure to secure the Transaction Financing and/or equity
line of credit could have a material adverse effect on the business…”, page 100

 1. Please expand this risk factor to specifically state that if the SPAC is unable to consummate the transaction
financing and/or equity line of credit, the SPAC may lack funds to consummate business combination and the risk that completion of the
Business Combination is conditioned on the satisfaction to secure the Transaction Financing and/or equity line of credit.

Response: In response to the
Staff’s comment, the Company has revised the referenced risk factor on page 101 of Amendment No.1 to specifically state that (i)
securing the Transaction Financing and/or equity line of credit is a condition to completing the Business Combination, and accordingly,
failure of the Company to secure the Transaction and/or equity line of credit may prevent consummation of the Business Combination and
(ii) failure to secure the equity line of credit could have a material adverse effect on the business, operations and financial performance
of the combined entity subsequent to the Business Combination.

will undergo a reorganization pursuant to which DigiAsia will convert the CLAs into shares of PT DAB, such that, following such conversion,
DigiAsia will hold 99.9999% of the entire issued capital of PT DAB. Please clarify whether the conversion will result in the consolidation
of PT DAB as a voting interest entity. Tell us what the effect of this conversion, as well as other changes, will have on the amount of
the non-controlling financial interest. In addition, tell us how you will account for the reorganization and whether pro forma information
should be provided.

Response:
In response to the Staff’s comment, the Company has revised its disclosure on pages 142, 244 and 246 of Amendment No.1 to clarify

 8. We note your disclosure on page 61
                                            and on pages F-51 and F-72, that the API revenues from one major customer accounted
                                            for approximately 87% and 92% of your total revenue for the years ended December 31,
                                            2022 and 2021, respectively, and that such arrangements are protected through multi-year
                                            contracts. Given that API sales accounted for a substantial majority your revenue, identify
                                            this major customer, disclose that material terms of the agreement with that customer including
                                            any termination provisions, and file agreement contract as an exhibit or tell us why
                                            it is not required. Additionally, tell us whether any material contractual rights may
                                            be triggered as a result of the business combination.

Response:
In response to the Staff’s comment, the Company has revised its disclosure on pages 62, 233 and 259 of Amendment No.1 to disclose, or provide a cross-reference to the disclosure of,
the material terms of the agreement with the major customer and clarify that no material contractual rights will be triggered as a result
of the Business Combination.

The
management of DigiAsia respectfully states that the key customer in question (i) has diversified revenue streams
providing software-as-a-service (“SaaS”)-based offerings, aggregating various digital products and services to
distributors and their merchants, (ii) has been running its business operations successfully for over 10 years and
(iii) has built a credible reputation with merchants on its platform. DigiAsia offers its services by way of APIs which enable
merchants on the customer’s platform to carry out their business on a day-to-day basis, in a faster, more robust, efficient
and secure manner including the ability to settle transactions and payments using several digital mechanisms. DigiAsia has been
receiving payments remittances against its revenue from the customer on a timely basis and the contract with the customer is for a
term of 10 years commencing from June 2, 2020, with the possibility of termination only (i) through the mutual consent of
both parties or (ii) by either party, in the event of the bankruptcy, insolvency and/or liquidation of the major customer.
There has not been any instances of material breaches or security issues since the commencement of the agreement that has warranted
a threat of termination.

DigiAsia
periodically conducts third-party penetration testing and audits to limit any potential security threats to DigiAsia’s system that
may impact the key customer’s operations and revenues derived from it. Further, should the customer close its business operations,
DigiAsia has the right to continue the existing connectivity to the existing merchants on the customer’s platform who are driving
the revenue and DigiAsia will be able to replace the gateway either on its own or through another third party. While there may be certain
costs involved in the re-onboarding of these merchants, due to the existing services offerings provided, DigiAsia does not view these
costs as material. Further, there may be a short-term impact on revenues while the merchants are being migrated to DigiAsia’s or
another third party’s system. Additionally, given that DigiAsia also onboards its own acquired merchants on the customer’s
platform with whom they have direct relationships, and such merchants contribute to a significant percentage of the overall merchant base
of the customer, even if the customer ceases to be a client of DigiAsia, DigiAsia considers that the impact on loss of merchants and end-users
will be limited and, consequently, the impact on DigiAsia’s revenue will be limited as well.

The customer is obligated to settle
its dues owed to DigiAsia as per agreed terms, from the date of the API hit, failing which DigiAsia can suspend its services and the contract
further elaborates the mechanism through which the customer may remediate its actions by way of clearing all receivables of DigiAsia.
The customer’s dependency on DigiAsia’s solutions is high, as identifying an alternative solution to seamlessly migrate to
another platform as well as obtaining merchant consents individually to migrate to another software or solution involves tedious tasks
and can cause significant disruption of operations for the distributors and merchants, which acts as a detriment for the customer to identify
any alternative solution provider for the services rendered by DigiAsia to them.

Further, the customer has a fairly
large customer base consisting of hundreds of various distributors and merchants, with the number increasing each year. The services offered
by DigiAsia in the form of APIs are availed of by the customer to enable further offering of its products and services to distributors
and merchants. As a result, the management of DigiAsia believes that although there is concentration risk towards a single customer, it
does not pose any significant threat to continue DigiAsia’s operations as a going concern

Given the competitiveness and
dynamics of the Indonesian market, price sensitivity is an important business driver to choose a service provider such as DigiAsia.
Accordingly, even if competitors may provide less comprehensive or less robust and reliable services and offerings, there exists the
possibility of competitors trying to significantly undercut DigiAsia’s pricing, to capture the customer’s business, just
by the disclosure of the name of the customer, and create additional competition and pricing pressure for DigiAsia, should the
client’s name be disclosed. DigiAsia’s management respectfully posits that disclosing the name of the customer would
cause irreparable harm to its competitive position, business, operations and financial condition. Further, DigiAsia’s
management respectfully submits that the summary of services and solutions being rendered to the customer and description of other
material terms of the agreement with the customer set forth in Amendment No. 1 adequately covers the relationship with the
customer and that providing the agreement as an exhibit to the registration statement will not provide additional pertinent
information to investors with respect to the services and solutions being provided to the customer and is not necessary for the protection of investors.

Response:

has revised its disclosure on page 242 of Amendment No.1 to clarify that DigiAsia does not currently have any issued patents or
pending patent applications.
