Cotool

Executive Summary

Cotool is a YC Spring 2025 pre-seed startup building customizable AI agents for security operations teams — automating detection engineering, threat hunting, and alert investigation in a single composable platform. The market thesis is real and well-timed: the agentic AI in cybersecurity segment is growing at 34.4% CAGR, SOC teams are chronically understaffed, and no single competitor has cleanly unified detection engineering automation with proactive threat hunting in an agent-first architecture. The founding team's operator credentials — all three co-founders shipped production security ML at Material Security — give them credible founder-market fit. The single biggest risk is competitive environment: Cotool has raised $500K against a field that includes CrowdStrike, Microsoft, and Palo Alto bundiing AI SecOps natively, Dropzone AI with $53.85M raised and 100+ enterprise customers, and 7AI which just closed a $130M round for a nearly identical pitch — all while Cotool is still in demo-booking, design-partner mode with a 6-12 month capital runway.
