Software you can charge for,built to run.
We run our own SaaS, so we build yours the way we would want it built: a data model that will survive year two, auth and billing done properly, and a deployment you can operate without us.

In short

How it works

Clickable prototypes so you see the product before we build it.

Weekly increments, typed and tested, demoed on a staging URL.
- 4

Pricing
From $5,000
An MVP with auth, billing and one core workflow starts at $5,000. Full products are scoped in phases with a fixed quote per phase.
Questions we get asked
- Which stack?
- Next.js, React, TypeScript, Node, Postgres or MongoDB, deployed on Cloudflare, Vercel or your own Kubernetes. Boring, well-supported choices on purpose.
- Do you take equity?
- No. Fixed quotes per phase, paid in milestones.
