Sleuth is a San Francisco software company founded by former Atlassian engineers who helped build Jira and Bitbucket. It began as a 'mission control' platform for continuous delivery, giving engineering teams automated DORA metrics and deployment tracking, then expanded into governing AI inside organizations. Its current product, Sleuth Skills, lets companies define agent skills, rules, prompts and MCP servers once and distribute them - with approval workflows, audit trails and access controls - across AI clients like Claude Code, Cursor, GitHub Copilot, Gemini and Codex. Sleuth has raised roughly $25M, including a $22M Series A led by Felicis in 2022.
Trunk is a San Francisco developer-tools company building a suite that keeps continuous integration reliable at scale. Its two flagship products - a parallel Merge Queue that batches and tests many pull requests at once, and Flaky Tests, which automatically detects and quarantines unreliable tests - target the bottlenecks that slow engineering teams as they ship more code, increasingly with AI assistance. Founded in 2021 by ex-Uber and ex-Google engineers, Trunk raised a $25M Series A led by Initialized Capital in 2022 and counts Brex, Faire, Zillow, and Gusto among its users.
Cortex is the engineering operations platform - an internal developer portal that catalogs services, scores them against engineering standards, and pushes teams to act on what's broken. Born out of the chaos of Uber-scale microservices, it gives platform teams a single pane of glass over ownership, quality, and operational maturity.
