Tolmo, a security startup founded by the team behind Sqreen, has raised $22 million in funding led by Accel, with Y Combinator participating. The company is valued at an undisclosed amount. Founded by Pierre Betouin, JB Aviat, Vlad de Turckheim and Arnaud Breton, Tolmo is building AI security agents for production environments. The startup addresses the growing challenge of AI-generated code and rapidly expanding codebases that security teams struggle to manage with existing tools. Tolmo's platform creates a Production Knowledge Graph by gathering context across production environments, then deploys AI agents to analyse pull requests, deployments and alerts. The system investigates security issues and proposes fixes using the full environmental context. The company is currently working with over 40 design partners and has its first pentesting agents in production.
