Hessian

YCombinator

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.

HEVN, inc

Global bank account for exporters

HEVN is a platform where companies can open business accounts with sponsor banks across the US, Europe, the UAE, Latin America, and Puerto Rico, and then move money between those accounts using stablecoin rails in minutes. It's a faster and more efficient alternative to SWIFT for international businesses that care a lot about speed of transaction and speed of complience checks. We're using AI to automate routine payments, paperwork and RFIs and minimise the losses that companies incur on stuck international wires.
