Meticulous careers

Meticulous's mission is to make the world's code safe, performant and reliable.

We're starting with a tool to catch JavaScript regressions in web applications with zero-effort from developers.

How it works: Insert a single line of JavaScript onto your site, and we record thousands of real user sessions. We then replay these sessions on new code to automatically catch bugs before they hit production. You can watch a 60-second demo at meticulous.ai/demo.

Catching JavaScript regressions is just the start. There is an entire category of products to build on top of replay. This ranges from automatic UI previews to revealing the performance impact of frontend code.

We are a London-based YC company and remote friendly. We just raised $4m, and are backed by some of the best founders and technical leaders in Silicon Valley, including Guillermo Rauch (founder Vercel, author next.js), Jason Warner (CTO GitHub), Scott Belsky (CPO Adobe), Calvin French-Owen (founder Segment), Jared Friedman (YC partner and former CTO of Scribd) and a bunch of other incredible folks.

We want to change the way the world develops software, and influence software approaches for decades to come.
