aid: chronicle-labs name: Chronicle Labs description: >- Chronicle Labs is a Y Combinator-backed (Spring 2026) company building infrastructure for teams running AI agents in production. The platform turns production data into staging environments: it reconstructs real end-to-end workflows from production data streams, generates test scenarios from those workflows, runs agents against replicated production environments (its Backtest Arena), and monitors live agents with autonomous fix and rollback. The pitch is to help engineering teams prove their AI agents work before they ship, replacing hand-built evals and "vibe-deploying" with backtesting against a team's actual operational reality. Typical customers run AI agents in customer service, payments, refunds, and other high-stakes workflows, and Chronicle Labs reports integrating with 100+ production tools. Founded in San Francisco by Ayman Saleh (CEO) and Rowan Zyadeh. At profiling time the product is accessed via a hosted web application behind sign-up; there is no public API, OpenAPI specification, or SDK, and the company publishes an llms.txt at its primary host. url: https://raw.githubusercontent.com/api-evangelist/chronicle-labs/refs/heads/main/apis.yml x-type: company x-source: vc-portfolio x-backed-by: - y-combinator x-tier: stub x-tier-reason: portfolio-lead accessModel: pricing: unknown onboarding: unknown trial: false try_now: false public: false label: Unknown confidence: low source: [] generated: '2026-07-22' method: derived specificationVersion: '0.20' created: '2026-07-17' modified: '2026-07-18' image: https://framerusercontent.com/images/eQyquoU7a6oSDASVNxovJDx70.png tags: - Company - AI Agents - Agent Testing - Agent Evaluation - Observability - Staging Environments - Backtesting - LLM Ops - Y Combinator - Artificial Intelligence apis: [] common: - type: DomainSecurity url: security/chronicle-labs-domain-security.yml - type: Website url: https://chronicle-labs.com - type: SignUp url: https://www.app.chronicle-labs.com/signup - type: Support url: https://chronicle-labs.com/book-call - type: LLMsTxt url: llms/chronicle-labs-llms.txt - type: WellKnown url: well-known/chronicle-labs-well-known.yml maintainers: - FN: Kin Lane email: kin@apievangelist.com - FN: APIs.json email: info@apis.io x-enrichment: date: '2026-07-19' status: backfilled pass: local-v1 note: backfilled from .gitignore signal + verified work evidence
