About Tolmo
Tolmo is a cybersecurity company developing an agent-driven security platform to protect cloud applications and infrastructure. The company was founded in 2026 by a team with extensive experience in offensive security and building security products. The four co-founders are Pierre Betouin, JB Aviat, Vlad de Turckheim, and Arnaud Breton. The founding team's journey is rooted in their previous venture, Sqreen, an application security company acquired by Datadog in 2021. Betouin and Aviat co-founded Sqreen, where they worked closely with de Turckheim and Breton. Their experience at Sqreen and subsequently at Datadog, where they built the security business, provided them with insights into the challenges of security at scale. This background, combined with experience at companies like Apple and Snyk, forms the foundation of Tolmo's approach to security. The name "Tolmo" is Greek for “I dare,” reflecting the team's ambition. Tolmo's platform addresses the security challenges posed by AI-driven software development, where code is generated at a pace that is difficult for human teams to secure manually. It operates by creating a "Production Knowledge Graph," a unified model that connects data from a company's entire production environment, including code, cloud services, CI/CD pipelines, and third-party vendors. This graph provides the necessary context for a fleet of specialized AI security agents to operate effectively. These autonomous agents work continuously to find vulnerabilities, detect misconfigurations, model threats, and remediate them, escalating issues to human teams only when necessary. The platform integrates with a client's stack through read-only access, requiring no deployment of agents or changes to code. In June 2026, Tolmo announced its launch from stealth with $22 million in funding led by Accel, with participation from Y Combinator and notable entrepreneurs in the security and cloud industries. The company's business model is a multi-tenant Software-as-a-Service (SaaS) hosted on AWS, targeting engineering and security teams. The founding team is building the tool they wished they had previously, aiming to redefine security for the modern, AI-powered development era.
