Founding Story

Founded by brothers Gabriel and Quentin Spencer-Harper in 2021, Meticulous was created to solve the problem of flaky and high-maintenance frontend tests. Gabriel, previously a software engineer at Dropbox, recognized that developers spend too much time on QA instead of shipping code, leading to the vision of a deterministic, recording-based testing engine.
