giftdetect· the right gift in minutesFrench startup Heal.dev has raised €4 million from Mango Capital and Alven to develop AI agents that detect and reproduce software bugs and security vulnerabilities before applications go live.
The pitch rests on a simple observation: AI has made writing code far faster, but not more reliable. Bugs, malfunctions and security holes are hard to spot before release, and they give cybercriminals openings to break into applications and compromise user data. "Producing more code does not mean producing more reliable applications," says co-founder and CEO Malo Marrec, who believes the next revolution in software development will be verification.
An agent that proves every anomaly
Founded in 2023 by Ben Lang, Pierre Oucif and Malo Marrec, Heal.dev initially focused on automating software tests. It has since pivoted to an AI agent that actively explores an application to find anomalies that traditional test suites can miss.
The agent does not simply flag suspicions. It reproduces and demonstrates each issue it finds, whether a security flaw or a display bug, before reporting it to engineering teams. The aim is to spare developers from wasting time on false alarms. According to the company, 70% of the failures its agent detects slip past traditional code review tools.
What the funding is for
The money will go mainly toward refining the technology, strengthening the product and engineering teams, and continuing commercial expansion in Europe. Heal.dev wants to improve its agents' ability to spot hard-to-detect anomalies in complex applications. About a dozen startups are already customers.
The company's longer-term ambition is to make proactive bug and vulnerability detection a reflex for every business that builds software. In an industry where AI can now generate code at scale, it argues, the ability to guarantee reliability could become one of the main competitive advantages.
