GRAYBOOK TECHNOLOGIES

About

We’ve spent careers keeping trading floors online.

Graybook Technologies was founded by infrastructure engineers who spent more than 25 years building networks and systems for global banks and hedge funds. We started the company to give smaller firms the same engineering, the same proximity to the exchange and the same discipline, without the bank-sized bill.

Principles we picked up on real trading desks.

Boring in production

The best trading infrastructure is the kind nobody talks about. We optimize for nothing happening at the open.

Measure everything

If we can’t timestamp it, we can’t improve it. Every system we run ships with the numbers to prove it works.

You own your stack

Open-source engines, documented builds and no lock-in. If you ever outgrow us, you leave with everything.

Built by people who ran the desks’ infrastructure.

Bank-grade engineering, sized for firms that trade fast and run lean. The numbers behind the team.
