Provenance Record

Well-structured News article covering a significant funding event. Clear 'What We Know / What We Don't Know' format works well. Technical details (vector database, exa-d, embedding models) add depth without becoming jargon-heavy. The 'What We Don't Know' section is a notable editorial strength that demonstrates appropriate epistemic humility.

All three sources fetched with HTTP 200. Snapshots read: source-0.html.gz (SiliconAngle), source-1.html.gz (PYMNTS), source-2.html.gz (TechStartups). Key facts verified: $250M raise (all sources), $2.2B valuation (all sources), a16z as lead investor (SiliconAngle — written 'Andersen Horowitz', clearly a typo; article correctly renders 'Andreessen Horowitz'), 5,000 companies (PYMNTS), 400,000 developers (SiliconAngle), Cursor/Cognition/HubSpot/OpenRouter/Monday.com clients (PYMNTS), $85M Series B with Nvidia and Y Combinator (SiliconAngle), Exa Instant <180ms (SiliconAngle), vector database one-tenth of a second (SiliconAngle), exa-d platform parallelizes across GPUs (SiliconAngle), custom embedding models on Nvidia cluster (SiliconAngle), Bryk quotes (PYMNTS and SiliconAngle), TechStartups 'cost of high-precision, AI-native retrieval' quote (exact match). No unverified claims found. All direct quotes verified as verbatim or accurately paraphrased from the cited source.

All quantitative claims (funding amount, valuation, customer count, developer count, latency spec, prior round size) trace to cited sources. The lead investor attribution (a16z/Andreessen Horowitz) is supported by SiliconAngle's text ('Andersen Horowitz' — an evident typographic error for the well-known firm). TechStartups lists the lead investor as 'Undisclosed', but does not contradict the a16z attribution. No fabricated statistics or hallucinated quotes detected.

Clean, well-sourced News article. All facts verified against snapshots, no fabrications or misattributions detected, strong structure with appropriate epistemic caveats. Ready for publication.
