Meticulous

Hey HN, I'm Gabriel, founder of Meticulous (YC S21). Our 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 https://www.meticulous.ai. Catching JavaScript regressions is just the start. We are a London-based YC company. 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.
