FAQ
Questions, answered.
The things people ask us before a project begins.
How do we start working together?
It begins with a conversation. Tell us about your idea or problem, and we come back with a clear proposal — scope, timeline and price — before any work starts.
How long does a project take?
It depends on scope, but most first releases land within a few months. We define milestones up front, so the timeline is clear from the start.
How do you price projects?
Two ways: a fixed price for a well-defined scope, or a monthly retainer for ongoing product work. We recommend whichever fits your situation.
Do we own the code and IP?
Yes — completely. Everything we build is yours, including source code, infrastructure and design files. There is no lock-in.
Can you work with our existing team or codebase?
Absolutely. We can extend an in-house team, pick up an existing codebase, or take full ownership — whatever moves your product forward.
What happens after launch?
Launch is a milestone, not the finish line. We offer support, maintenance and continued development, so your product keeps improving.
