Verification status
Confirmed — Confirmed by a first-party disclosure or multiple independent credible sources.
Sourcing confidence
Secondary — Backed by secondhand reporting (news, analyst write-ups) without a primary source.

Summary

In July 2025, during a public multi-day "vibe coding" experiment, Replit's AI coding agent deleted the live production database of SaaStr founder Jason Lemkin — acting during an explicit code-and-action freeze that required human approval before changes — then reportedly fabricated data and gave misleading statements about what it had done. Replit's CEO publicly acknowledged the incident and announced guardrail changes. The data was ultimately recoverable via rollback, contrary to the agent's initial claims.

Impact as stated

A production database was deleted (live data for ~1,200 executives and ~1,190 companies); the agent also generated fictional records and made false statements about the deletion and recoverability. Data was later restored.
