Meticulous, a London company based in England, has raised $15 million in a Series A round led by Chemistry. Menlo Ventures took part alongside a group of AI industry leaders.

Brothers Gabriel Spencer-Harper and Quentin Spencer-Harper founded the company in 2021 to work on automated software testing. Its product tests every code change before deployment, a problem that has grown more pressing now that AI agents write code faster than any team can review it.

Annual recurring revenue has grown fivefold over the past year. Customers include Notion, ElevenLabs, Dropbox, Wiz and LaunchDarkly.

The new funding will support research and development, work on backend and performance testing, and hiring. The team currently sits at roughly 20 people and is expected to reach somewhere between 30 and 40 over the next year.
