Claims
- [verified]
Baseten raised a $1.5B Series F in June 2026 at a $13B valuation
Confirmed by Baseten's own announcement and independent TechCrunch reporting. Fine print: TechCrunch reports the round was split-priced, with some investors paying in at an $11B valuation rather than the full $13B headline figure.
- [verified]
Baseten raised a $300M Series E in January 2026 at a $5B valuation, with Nvidia participating
Confirmed by company blog and Bloomberg. Led by IVP and CapitalG.
- [verified]
Baseten raised a $150M Series D in September 2025 at a $2.15B valuation
Businesswire press release URL retrieved via search (direct fetch twice timed out); figure independently corroborated inside Bloomberg's later Series E coverage, which cites the $150M/$2.15B round as prior history.
- [verified]
Baseten's revenue grew 20x and inference volume grew 40x over the year preceding the Series F (June 2026)
Company's own stated multiple, not an absolute dollar figure. Note the Series E blog five months earlier claimed inference volume grew 100x over its own trailing year, a different measurement window, so the two multiples are not directly comparable.
- [plausible]
Baseten's annualized revenue hit $600M in March 2026, up from $200M in December 2025 (roughly 3x in one quarter, ~1,900% YoY)
Traces to a single primary source, The Information's paywalled exclusive (only the summary tweet was retrievable here). Sacra's write-up repeating the figure explicitly labels it 'Sacra estimates, not Baseten-disclosed audited financials.' Baseten itself has not published an absolute ARR number in its own blog posts.
- [verified]
Baseten was founded in 2019 by Tuhin Srivastava, Amir Haghighat, Pankaj Gupta, and Philip Howes
Confirmed by the company's own about page and independent research profile.
- [verified]
Named customers include Cursor, Notion, Lovable, Harvey, HubSpot, OpenEvidence, Abridge, Decagon, Parallel, Clay, and Mercor
Named directly in Baseten's own funding announcements.
- [thin]
Baseten headcount
No official disclosure found. Third-party trackers disagree widely: RocketReach ~238, Datanyze ~279, PitchBook ~312, Tracxn ~319 as of mid-2026, Silicon Valley Investclub '150+' for Q1 2026. Not company-confirmed; excluded from a confident verdict.
Gaps
- No official, audited headcount figure from Baseten itself.
- The $600M ARR figure rests on one paywalled report (The Information) plus a third-party estimate site (Sacra) that flags it as an estimate, not a company-disclosed number.
- Could not directly fetch the full businesswire Series D press release (repeated timeouts); relied on the URL surfaced in search results plus corroborating mentions in later Bloomberg coverage.
