Products we build and run

Grymman is a product company that also takes client work. These six products are live in production under our own name — mobile apps, AI agents, data APIs and web platforms. Each page below explains what the product does and the engineering behind it.

Why we run our own products

Most development agencies sell hours. We sell hours too, but the reason to hire us is on this page: we carry the cost of running software we built, which is a different discipline from shipping it and walking away.

An app you operate teaches you things a client project never will. You find out what happens when a county data portal changes its response format on a Tuesday morning. You find out which LLM prompt patterns hold up after ten thousand real users and which ones fall apart. You find out what App Store review actually rejects. Every one of those lessons is already paid for by the time a client project starts.

What these products have in common

How a client engagement works

We start with the smallest version of your idea that a real user can react to, get it in front of people, and iterate from there. For mobile that usually means a native build in Swift or a cross-platform build in React Native, published to the store under your own developer account. For AI work it means a narrow, well-scoped agent that does one job reliably before it does five jobs badly.

We respond to enquiries within 24 hours. Tell us what you are trying to ship.
