Theorem is a formal verification and AI research company working to make software proofs cheaper to produce. It argues verification covers entire behavior spaces ahead of time and is starting with verified sandboxes that agents cannot escape or game.
Security and platform teams exploring mathematically verified components and agent-safe sandboxes rather than heuristic guardrails alone.
Public site focuses on research posts and careers without self-serve product pricing or signup flows.
Theorem combines formal methods with AI engineering, arguing cheap proof generation is the durable defense as adversaries scale.

cmux is a free, open-source macOS terminal built on Ghostty for multitasking with AI coding agents. It adds vertical tabs, split panes, notification rings, an in-app browser, and optional cloud VMs on paid plans for remote agent sandboxes.
Explore toolAgentMail is an email inbox API built for AI agents, giving each agent its own inbox to create threads, send and receive mail, handle attachments, and integrate via SDKs or MCP. The product targets developers wiring agents into real email workflows with multi-tenant controls and optional custom domains.
Explore toolUsage-based plans start free and scale to Developer and Startup tiers for production agent workloads.
