Explanation of Responses:

1. Represents the sale of shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of 31,876 restricted stock units on September 10, 2021. These sales are mandated by the Issuer's election under its equity incentive plan to require the satisfaction of tax withholding obligations to be funded by a "sell to cover" transaction and do not represent discretionary trades by the Reporting Person.

2. Represents a correction to an aggregation of direct and indirect holdings of Class A Common Stock on the Reporting Person's Form 4 filed on February 11, 2021 (the "February Form 4"). The correct amount in Box 5 of the third row of the February Form 4 is 15,000, and the correct amount in Box 5 of the fourth row of the February Form 4 and in the second row of the Reporting Person's Form 4 filed August 11, 2021 is 0. No Class A Common Stock is held by Viant Technology Equity Plan LLC for the account of the Reporting Person.

3. The Reporting Person's indirect Class B Common Stock holdings are being reported on this Form 4 to clarify the number of securities of the Issuer indirectly held by the Reporting Person through Viant Technology Equity Plan LLC. No securities of the Issuer are held by the Reporting Person other than those shares of Class A Common Stock held directly and Class B Common Stock held indirectly as reported on this Form 4.
