Questions
Before you book
Do we need AI in our app?
Not always. In the first call we'll tell you if a simpler feature solves the problem better. We only recommend AI where it saves time, earns revenue or does something that wasn't possible before.
Is our data safe?
Your data stays in your accounts. We use providers that don't train on your data, keep access scoped per user, and log what the AI reads and returns.
How do you keep AI answers accurate?
We build a test set of real questions with known answers and run every change against it. Answers cite their sources, and low-confidence cases go to a person.
Who owns the code?
You do. You get the full repository, infrastructure access and documentation at handoff.
Can you work with our existing team?
Yes. We often build the AI layer while your team owns the core product, with shared repos and weekly syncs.
