Why Trunk is interesting
Ex-Uber engineers built Trunk to keep main green at scale: parallel merge queues, flaky-test detection, and monorepo-aware CI — a16z led seed and co-led the $25M Series A with Initialized.
Key facts

- Seed: $3.5M led by a16z (VentureBeat)

FAQs about Trunk
Funding context and why this company shows up in venture coverage.
Trunk provides developer workflow tools — notably an enterprise merge queue that tests pull requests against latest main in parallel, plus code-quality checks and CI integrations.
Andreessen Horowitz led the seed and participated in the $25M Series A co-led with Initialized Capital. See /fund/andreessen-horowitz and /fund/initialized-capital.
Trunk raised $25M Series A in April 2022 (~$31M total) and remains private.
Broken main branches and flaky CI stall velocity. Trunk's merge queue serializes merges safely while parallelizing unrelated PRs — critical for monorepos with expensive test suites.
No — Trunk remains private as of July 2026.
