Buyer analysis

Best fit: Buyers needing expert human-feedback/RLHF data plus realistic enterprise-workflow RL environments and rubric-based agent evaluation from an established, frontier-lab-trusted vendor.

How we verified this

Confirmed this is the correct company matching the directory note ('human-data leader, environments on the side'): Surge AI / Surge Labs Inc., SF, founded by Edwin Chen, RLHF/human-data platform that has added agentic RL environments (EnterpriseBench/CoreCraft, arXiv:2602.16179). Highest-risk findings: (1) Funding is NOT closed, Bloomberg (Jul 2025) reported only 'talks' for ~$1B at 'at least $25B'; the draft's '$15B-$25B+' conflated Reuters ($15B sought) and Bloomberg ($25B); a LinkedIn post claiming a closed $30B round and getlatka's $20B are weak/inconsistent and rejected. Kept total_raised/last_round/valuation at 'reported' and notable_investors empty (Bloomberg named only POTENTIAL investors). (2) Headcount band 51-200 confirmed via LinkedIn+Craft; the company is ~110-121 FTE (Pitchbook ~250 is an outlier). (3) Customers: Anthropic confirmed via a Jared Kaplan endorsement (on Surge's own blog) and corroborated by third-party Sacra; Google/Meta/Microsoft verified via third-party Sacra/Inc.; OpenAI corrected to a FORMER customer (Forbes, Sept 2025, citing an OpenAI spokesperson that they no longer work with Surge). (4) No SOC 2 / trust page found, left unknown. (5) Revenue: $1.2B (2024) is multi-source; $1.4B ARR is getlatka-only and flagged weak. founded_year downgraded to 'reported' (Wikipedia-only, minor 2020/2021/2018 disagreement). Segment preserved verbatim; focus_areas all within the controlled vocabulary. Overall confidence: medium.
