Reported financing.[14]
post-money valuation and the full investor list are not publicly disclosed.
Zero. The company explicitly states it accepts no investor funding and is entirely user-revenue supported.[23]
Not disclosed. Third-party estimates of ~$350M circulated in April 2026 are media inference based on estimated ARR, not a disclosed round or transaction.[1][3][19]
Multiple media sources estimated ~$25M ARR as of early 2026. Latka, a separate data aggregator, estimated only $2M ARR for the same period. The company has not published revenue figures; both numbers are unverified.[2][3][22]
Obsidian Security (obsidiansecurity.com), a distinct SaaS cybersecurity firm, raised $85M at a $1.1B valuation in a Series D led by Crescent Cove Advisors in August 2026. This is a different company and should not be attributed to obsidian.md.[12][13][14]
