Company profile

researched Aug 2026

Tolmo is a security platform that deploys fleets of autonomous AI agents across a customer's production stack. The system first builds a live "Production Knowledge Graph" that ingests context and metadata from cloud providers, code repositories, CI/CD pipelines, containers, databases, identity systems, observability tools and third-party security vendors, then links code to its deployments and surrounding services. Specialized agents reason over this graph on every pull request, deployment and alert so that findings arrive with full environmental context rather than as isolated signals.

The product includes a Pentesting Agent that performs continuous adversarial testing of live environments and aims to prove real exploitability, an Internal Discovery Agent that inventories assets and infers cross-service dependencies from configuration while classifying what datastores hold and who accesses them, and a Remediation Agent that ships verified fixes, reviews changes at the pull-request level against the graph and computes blast radius. Tolmo also markets a 24/7 incident response team for customers under attack. Its stated coverage extends across code, CI, cloud applications and specification documents, with agents triaging, verifying impact and remediating autonomously and escalating to humans only when necessary.

A command-line interface is available (installable via Homebrew, an install script or a Debian package) that lets teams run SQL and Cypher queries against the infrastructure graph, manage and triage security findings with an audit trail, proxy authenticated requests to connected services such as GitHub, AWS, Linear, Sentry and Datadog without credentials leaving the backend, download threat-model pipeline artifacts, manage Datadog monitors, query historical graph state via temporal attributes, and install a Tolmo skill into Claude Code and other AI agents.

Founding story

The four co-founders β€” Pierre Betouin, JB Aviat, Vlad de Turckheim and Arnaud Breton β€” previously built Sqreen, an early runtime application security company that reached 800 customers in production and was acquired by Datadog in 2021. They then spent years building Datadog's security business and working with engineering and security teams across thousands of companies. According to the founders, observing how runtime observability transformed engineering work, and the widening gap between development velocity and security tooling as AI generates code, led them to start Tolmo as the tool they wanted but could not find.

Business model

Tolmo sells a SaaS security platform to organizations, offering self-serve sign-up and sales-led demos, with a waitlist at launch and design-partner engagements preceding general availability. A 24/7 response team is offered alongside the automated agents.

Traction

At the time of its June 2026 launch, Tolmo reported more than 40 design partners with the product deployed in production, hundreds of critical security findings surfaced in real production environments, and the first fleet of Pentesting Agents live with customers. Team size was about 12.

Latest developments

Accel published its investment note on June 18, 2026, describing Tolmo's Production Knowledge Graph approach. The company's blog features agent-authored security research, including analyses of AI-generated kernel code and malicious package techniques in npm, PyPI and Crates ecosystems, and Tolmo stated additional agents beyond pentesting were rolling out.

Market position

Tolmo positions itself as an agent-native alternative to traditional application security and cloud posture tooling, arguing that scanner- and ticket-based workflows cannot match the pace of AI-generated code or attackers who weaponize vulnerabilities in about 1.5 days while defenders typically respond in weeks. Third-party analysis places it against traditional AppSec vendors such as Snyk and Veracode, CNAPP/cloud posture products such as Wiz and Prisma, observability-plus-security offerings such as Datadog Security, and manual human-led review, with Tolmo's differentiator framed as contextual autonomous automation across the full production stack.

Tolmo emphasizes that findings are grounded in a live, connected model of the customer's actual production environment with historical state, so agents can prove exploitability, assess blast radius and produce verified fixes instead of emitting standalone alerts. Deployment is read-only and requires no in-environment agents or code changes. The founding team's prior experience building Sqreen's runtime application security product and Datadog's security business is presented as the basis for combining observability, security and AI.

Technology

The core technology is a continuously updated production knowledge graph that stitches together code, infrastructure, deployments, CI, observability and security-vendor data and retains a history of every change, described as a "time machine" that supports temporal queries of past infrastructure state. On top of the graph, a fleet of specialized AI security agents (pentesting, cloud configuration, security monitoring, application security, runtime defense, recon, remediation and others) reason over the full environment, verify exploitability, and load context into coding agents to propose fixes. Integration is via read-only roles with no in-environment agents to deploy and no code changes required. Access is also exposed through a CLI supporting SQL and Cypher queries and credential-proxied calls to connected services.

Go-to-market

Tolmo launched publicly out of stealth in June 2026 with a founder blog post, a Y Combinator launch, investor coverage and a waitlist, and works with more than 40 design partners running the platform in production. It offers self-serve onboarding and demos, publishes security research and agent findings on a company blog and newsletter, and was hiring across security, AI, product engineering and go-to-market roles.

Security, platform and engineering teams at organizations shipping software rapidly, particularly those using AI coding agents, where the volume of code and configuration change outpaces manual review and traditional AppSec processes.

Geography

Headquartered in San Francisco, with some teams remote.

History

Tolmo was founded in 2026 and participated in Y Combinator's Spring 2026 batch, with Nicolas Dessaigne as primary partner. It came out of stealth in mid-June 2026, announcing a $22M seed round led by Accel with participation from Y Combinator and a group of angel investors, alongside its first design-partner cohort and a live Pentesting Agent fleet.
