What Colyon does
Colyon is a London-headquartered AI research and product studio founded in 2025 that builds collaborative multi-agent AI systems, with its commercial focus on Web3 security via the Monchain platform. The company's core architecture connects specialized AI agents — behavioral, graph, semantic, and sanctions — through a shared intelligence layer, enabling them to collaborate in parallel and produce explainable, reproducible risk decisions. This architecture underpins two products: Monchain Check, an enterprise API/SDK platform delivering real-time crypto fraud detection (96% accuracy, sub-420ms P95 latency) to exchanges, wallets, fintechs, and compliance teams; and Monchain Wallet, a non-custodial consumer wallet with proactive fraud blocking and AI-driven trading signals distributed via waitlist.
Colyon's go-to-market combines enterprise field sales (direct outreach, API-first distribution, embedded SDK widgets for React, React Native, Flutter, Swift) with a product-led growth motion through the consumer wallet waitlist. Distribution is anchored by direct connectors into institutional custody providers (Fireblocks, Copper, BitGo) and SOC tooling (Slack, PagerDuty, ServiceNow, Jira, SIEM), positioning the product for regulated enterprise procurement. Differentiators include a closed-loop learning data flywheel (500K+ addresses screened, 27 chains, 180K smart contracts, 95 exchanges monitored, 1.8B telemetry signals per minute), regulatory readiness (SOC 2 Type II, GDPR, Travel Rule, AMLD6, MAS PSN02, NYDFS 504), and proprietary research IP in GraphSwarm and game-theoretic multi-agent reinforcement learning. The company operates remote-first with optional hubs in London and San Francisco, has fewer than 10 disclosed employees, and has not yet publicly disclosed funding or revenue.
