Obsidian has raised $85 Million in new Series D funding

August 19, 2026 Craig Etkin

According to filings with the U.S. Securities and Exchange Commission, Obsidian has raised $85 Million in new Series D funding. The federal securities law requires the notice to be filed by companies that have sold securities without registration under the Securities Act of 1933 in an offering made under Rule 504 or 506 of Regulation D or Section 4(a)(5) of the Securities Act. A company must file this notice within 15 days after the first sale of securities in the offering. For this purpose, the date of first sale is the date on which the first investor is irrevocably contractually committed to invest. Each issuer of securities that sells its securities in reliance on an exemption provided in Regulation D or Section 4(a)(5) of the Securities Act of 1933 must file this notice containing the information requested with the U.S. Securities and Exchange Commission (SEC) and with the state(s) requiring it. If more than one issuer has sold its securities in the same transaction, all issuers should be identified in this filing with the SEC.

Investors in the company’s current round of funding include: Crescent Cove Advisors, Greylock Partners, and Menlo Ventures
