THE PROBLEM WE SOLVE
Most SaaS products spend their first months rebuilding the same plumbing: sign-up, teams, permissions, billing and an admin area.
Our foundations already solve those parts, so your budget goes into the features that make your product different, including AI that works with your customers’ own data.
BUILT FOR
PLATFORMS & TOOLS
KEY FEATURES
01
Each customer’s data is isolated, with role-based access control for every user.

04
Plans, trials and usage limits are wired to automated billing.
05
A documented API and keys let customers connect your product to their tools.

FAQ
Yes. The foundation becomes part of your codebase, and you own all of it, including the parts we started from.
OpenAI, Anthropic and open-source models are all supported. We choose based on cost, accuracy and where your data must stay.
Yes. We review the codebase first, then either extend it or move parts onto the foundation step by step.
It depends on the systems and data involved. After a short discovery you get a fixed-price estimate for the build and a clear monthly figure for hosting and support.
We monitor the integration, fix issues fast and update it when the connected systems change versions. You own the code, data and accounts from day one.
