Runtime
Sandboxed coding agents for everyone on your team.
Note: This is a preliminary assessment based on limited publicly available information. We did not have access to LinkedIn profiles or live product screenshots for this analysis. We will update this entry with a more thorough review soon.
Verdict
Strong founding team with rare combination: a prior YC exit (Gus) and a CTO (Carlos) with proven ability to build and scale critical fintech infrastructure at Modern Treasury, Finix, and Hulu — this isn't a resume play, this is a team that has shipped hard things. The product targets a real and urgent problem: as coding agents proliferate, enterprise risk/observability tooling is genuinely lagging. Main concerns are competitive moat (big platforms could absorb sandbox/guardrail features natively) and lack of publicly verifiable traction or customer names. The 'live with YC scaleups' claim is promising but unverified. Needs to show named customers and revenue growth to cross into S.
