Trunk

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.
