Common questions

Custom App Build, answered.

What do I get with a prototype build?
A scoped, full-stack product taken from discovery through a working, deployable release you can put in front of users or investors — core features implemented end to end, plus testing, deployment, handoff, and documentation.
How is it priced?
Prototypes are fixed-price, typically $3,000–$7,500, with 50% due up front and 50% on delivery. We define the scope and price before writing any code, so you know exactly what you are getting.
Who is this for?
Entrepreneurs and platform founders who need something real — for a first launch, early users, or investor conversations — rather than an open-ended, hourly development engagement.
