Why it matters here

Little direct relevance; useful technical contact on how expert-authored tasks become verifiable RL environments.

How to reach

Speculative: X or LinkedIn; technical questions on verifier design.

What we could not establish
  • An X account @wyattgmarshall also exists; YC links @wgm752, which is used here.
  • Names of the prior NYC startups unknown.
