**Item 1. Security and Issuer**

**(a) Title of Class of Securities:**
Common Stock, par value $0.0001 per share

**(b) Name of Issuer:**
ON24 INC.

**(c) Address of Issuer's Principal Executive Offices:**
50 BEALE STREET, 8TH FLOOR, SAN FRANCISCO, CA, 94105

This Amendment No. 5 (this "Amendment No. 5" or this "Schedule 13D/A") amends and supplements the statement on Schedule 13D originally filed with the Securities and Exchange Commission (the "SEC") on February 14, 2023 and amended on March 13, 2023, August 11, 2023, January 16, 2024 and May 14, 2025 (as amended, the "Statement") by the Reporting Persons. Unless otherwise defined herein, capitalized terms used in this Amendment No. 5 shall have the meanings ascribed to them in the Statement. Unless amended or supplemented below, the information in the Statement remains unchanged.

**Item 5. Interest in Securities of the Issuer**

**(a)**
Rows 11 and 13 of each Reporting Person's cover page to this Schedule 13D/A set forth the aggregate number of shares of common stock and percentages of the shares of common stock beneficially owned by such Reporting Person and are incorporated by reference. The percentage set forth in each row 13 is based upon the sum of (i) 42,475,166 shares of the Issuer's common stock outstanding as of May 1, 2025, as reported in the Issuer's Quarterly Report on Form 10-Q filed with the SEC on May 8, 2025 and (ii) with respect to Ms. Paul, 30,198 shares of common stock issuable upon the settlement of restricted stock units within 60 days.

The Reporting Persons' ownership of the Issuer's securities consists of (i) 8,260,424 shares of common stock held directly by Lynrock Fund; (ii) 59,877 shares of common stock held by Ms. Paul; and (iii) 30,198 shares of common stock issuable upon the settlement of restricted stock units held by Ms. Paul within 60 days.  The preceding does not include an aggregate of 19,165 shares of common stock underlying restricted stock unit awards granted to Ms. Paul pursuant to the Issuer's Non-employee Director Compensation Policy. The shares underlying the awards are reported as common stock beneficially owned by Ms. Paul in her reports filed pursuant to Section 16 of the Exchange Act in accordance with applicable provisions of Section 16 of the Securities Exchange Act and SEC staff interpretive positions. However, because the shares underlying the restricted stock unit awards may not be acquired by Ms. Paul within 60 days of the date hereof, they are not considered to be beneficially owned by Ms. Paul for purposes of Section 13 of the Securities Exchange Act and, therefore, are excluded from the shares reported herein as beneficially owned.

Lynrock Lake LP (the "Investment Manager") is the investment manager of Lynrock Fund, and pursuant to an investment management agreement, the Investment Manager has been delegated full voting and investment power over securities of the Issuer held by Lynrock Fund. Ms. Paul, the Chief Investment Officer of the Investment Manager and Sole Member of Lynrock Lake Partners LLC (the "General Partner"), the general partner of the Investment Manager, may be deemed to exercise voting and investment power over securities of the Issuer held by Lynrock Fund.

**(b)**
Rows 7 through 10 of each Reporting Person's cover page to this Schedule 13D/A set forth the number of shares of common stock as to which such Reporting Person has the sole or shared power to vote or direct the vote and sole or shared power to dispose or to direct the disposition and are incorporated by reference.

**(c)**
Except as set forth herein, none of the Reporting Persons has effected any transactions with respect to the securities of the Issuer since the most recent amendment to this Schedule 13D.
