About
I am building Charter because agents break on the messy reality of business software, and nobody can test for it.
I'm Hatem Elsisi. I founded Charter. I graduated from Minerva University in 2026 with a degree in computer science and business, and I live in San Francisco.
What I saw
I author graded browser tasks for an expert-data vendor that sells to AI labs. The work is simple to describe. Write a task a weak agent gets wrong. Write a verifier that checks the end state. Do it inside software that behaves like what a real business runs.
That last part is where it breaks. Agents rarely fail on the happy path. They fail on the duplicate customer, the locked month, the invoice someone half-edited last week. Empty vendor sandboxes and rebuilt copies leave all of that out, so an agent that passes there breaks at its first customer.
Why Charter
Hundreds of startups now build agents for dental practices, property managers, freight brokers, field service and agencies. Each one has to test somewhere, and today that means an empty sandbox, a mock, or a customer's live system.
Charter gives them the real product instead. A vendor licenses a resettable sandbox, Charter seeds it with a realistic synthetic tenant and a graded test suite, and agent teams run it on every change. The vendor gets 30 percent. No customer data ever enters an instance.
Why me
I sit on the side of the table that writes the tests, so I know where agents break and how to grade it. I also ship. I build full products alone in about a day with a fleet of coding agents. The first environment, Kimai, went live on November 2, 2026. Vendor licensing is open now.
I speak Arabic and English natively. My code is at github.com/elsisiem.
