On behalf of our client, Direct Digital Holdings, Inc. (the “Company”), we submit this letter in response to comments from the staff of the Division of Corporation Finance (the “Staff”) of the Securities and Exchange Commission (the “Commission”) contained in its letter dated February 3, 2022, relating to the above referenced Amendment No. 3 to the Registration Statement on Form S-1 (the “Amendment No. 3”). This letter and our Amendment No. 5 to the Registration Statement on Form S-1 (the “Amendment No. 5”) are being filed with the Commission via EDGAR electronically today. In addition to the electronic filing, we are delivering via email a copy of this letter, along with a courtesy copy of the Amendment No. 5 marked to indicate changes from the Amendment No. 3 filed on January 31, 2022.

Each of our responses is set forth in ordinary type beneath the corresponding Staff comment, which is set out in bold type. Except for page references appearing in the headings and Staff comments below (which are references to the Amendment No. 3), the page references in our responses are to pages in the Amendment No. 5.

Amendment No. 3 to the Registration Statement on Form S-1 filed January 31, 2022 Capitalization, page 63

Response:

The Company advises the Staff that the Company has revised the disclosure on page 63 of Amendment No. 5 to add a column disclosing the capitalization of the Company on a pro forma basis to give effect to the Organizational Transactions (as defined in Amendment No. 5), excluding the effects of the offering.

Unaudited Pro Forma Consolidated Financial Information, page 68

Response:

The Company advises the Staff that the Company has revised Amendment No. 5 to remove the pro forma consolidated statement of operations for the nine months ended September 30, 2020. In its place, the Company is including (i) an actual consolidated statement of operations for the nine months ended September 30, 2021, (ii) a consolidated statement of operations for the nine months ended September 30, 2021 giving pro forma effect to the Organizational Transactions, excluding the offering, and (iii) a consolidated statement of operations for the nine months ended September 30, 2021 giving pro forma effect to the Organizational Transactions, including the offering. Because the acquisition of Orange142, LLC (“Orange142”) was completed during the fiscal year ended December 31, 2020, Orange142’s financial results of operations were included in the Company’s consolidated results for the entirety of the nine-month period ended September 30, 2021, and accordingly, any additional pro forma effect of the acquisition of Orange142 for such nine-month period is unnecessary.

Pro Forma Consolidated Statements of Operations, page 71

Response:

The Company advises the Staff that the Company has revised Amendment No. 5 to add pro forma earnings per share data for all periods presented.

Response:

As noted above in our response to comment number 2, the Company advises the Staff that the Company has revised Amendment No. 5 to remove the pro forma consolidated statement of operations for the nine months ended September 30, 2020. In its place, the Company is including (i) an actual consolidated statement of operations for the nine months ended September 30, 2021, (ii) a consolidated statement of operations for the nine months ended September 30, 2021 giving pro forma effect to the Organizational Transactions, excluding the offering, and (iii) a consolidated statement of operations for the nine months ended September 30, 2021 giving pro forma effect to the Organizational Transactions, including the offering. No additional adjustments to such nine-month period are necessary due to the reasons set forth in our response to comment number 2.

Pro Forma Balance Sheet, page 73

Response:

The Company advises the Staff that the Company has revised Amendment No. 5 to remove the historic balance sheet information, actual and pro forma, as of December 31, 2020.

Response:

The Company advises the Staff that the Company has revised Amendment No. 5 to quantify each pro forma balance sheet adjustment giving effect to the Organizational Transactions, including a reference to sufficiently detailed footnotes thereto.
