About Hessian
Summary
Hessian builds and operates AI agents that automate business operations for B2B companies. Engineers deploy on-site to map existing workflows, then build and run agents end-to-end on Hessian's own platform, replacing the manual knowledge work that in-house teams cannot scale. The model differs from off-the-shelf automation tools: Hessian owns the software and continues operating it, making it closer to a managed service than a self-serve product.
Business model
A forward-deployed, managed-service engagement where Hessian builds and runs the agents on behalf of each customer.
Go-to-market
Hessian targets B2B companies with operational workflows too complex for generic tools, acquiring customers through a sales-led, demo-first motion where engineers go on-site to scope and then build the solution.

Forward-deployed AI Agents
Hessian is the platform for automating business operations with AI agents. We forward deploy on-site to map the work, and build the agents on our platform to run it end-to-end. Unlike off-the-shelf tools that don't know your business, you get a partner that owns the software and operates it every day. Why now? Coding agents have matured to the point where, combined with our engineering judgment we've built across a decade of shipping production systems, we can scale forward-deployed engagements with minimal headcount. Furthermore, our FDE agents and tooling will accelerate how quickly we automate workflows on our platform. We're already saving our customers hundreds of hours a month. Trillions of dollars a year are spent on knowledge work, and we're building the standard for how every company deploys, operates, and governs the AI agents that do it.
