www.halluminate.ai ↗ · Status: active confirmed · Founded 2024

Halluminate (YC S25, founded 2024, San Francisco) builds managed reinforcement-learning sandbox environments, simulated applications, and human/annotation data plus evaluation benchmarks (WebBench, BrowserBench, Westworld) to train and test computer-use and browser AI agents. Its 2026 site positioning has narrowed toward 'RL environments for financial services' (investment banking, private equity, consulting).

Buyer analysis

Best fit: Foundation-model labs and browser/computer-use agent teams needing deterministic, managed RL sandboxes plus expert eval/annotation data, increasingly for finance workflows.

How we verified this

Confirmed this is the correct company matching the directory note 'computer use, done deterministically': YC and LinkedIn explicitly describe Halluminate as infrastructure (managed sandboxes + data + benchmarks) for training computer-use AI agents, with offline/deterministic sandboxes referenced in the Launch HN. Founded 2024, SF, YC S25, founders Jerry Wu (ex-Capital One Labs) and Wyatt Marshall, all confirmed via YC. Open-source org and licenses (WebBench MIT, westworld Apache-2.0, noodle-flights MIT, browserbench no license) confirmed on GitHub. Key downgrades: headcount (getlatka '12' conflicts with YC team size 5 and LinkedIn 2-10; band corrected to 1-10), valuation ($4M getlatka estimate -> unknown), and revenue (~$1.3M ARR -> unverified estimate) because getlatka is a single, internally inconsistent source (it claims $0 raised despite YC/angel backing). Investor list expanded to 7 via PitchBook (added Batch Ventures, Team Ignite Ventures, Transpose Platform Management). Funding figures conflict across sources ($160K PitchBook vs ~$500K vs $0) with no official announcement, so kept at 'reported' with the conflict documented. All customer claims remain self-claimed (unnamed labs/browser-agent companies, OpenAI/Anthropic per company copy), no third-party verification found, so none upgraded to verified. SOC2/certifications/security page not found; left unknown. Overall confidence: medium.
