Sonarly
ActiveMakes software self-healing
About
We want software to improve itself. Sonarly connects to your monitoring stack - tools like Sentry, Datadog, and Grafana - and triages every alert to remove noise and duplicates. It then investigates logs, traces, metrics, and code to build a living map of your production system and find root cause. The result is either a ready-to-merge fix PR or a recommendation to update your alerting rules so the noise never comes back.

Two years ago, I moved from a random village in France to Paris to study CS. I started building my first startup with Alex and we scaled it to 100k+ users in 6 months. It's funny because it was the Duolingo for finding schools and it made us drop out. Now we're building Sonarly (YC W26), giving coding agents the context they need to fix production bugs automatically.
I started freelancing at 15 doing web scraping, then quickly became a full-stack developer and later an AI engineer training ML and deep learning models. I dropped out of computer science school to co-found Meoria, a career-guidance app that helped over 100,000 French students navigate Parcoursup but the market moved too slow for our ambition. Now I’m building Sonarly: the platform that instantly detects and fixes production bugs before your users ever notice them.
Launch
Automatically triages production alerts, investigates root causes, and fixes bugs in the background.
Sonarly is an autonomous on-call engineer that integrates with Sentry, Datadog, and user feedback channels to triage alerts, investigate root causes, and automatically fix bugs in production, using production context to reduce MTTR and keep systems running smoothly for users.
