Listen
We ask about your goal and budget first. What to build comes after.
- 02
Show
We align on direction with a working prototype, not a planning deck.
- 03
Build
We share builds on a fixed cadence, so you never have to ask where things stand.
- 04
Keep
We keep operating and improving it after launch.
FAQ
How much does it cost?
It depends on scope. Tell us your goal, timeline and budget range, and we'll send a scope and quote within 3 business days. Quotes are free.
How are payments split?
Three stages — upfront, interim and final — with ratios fixed in the contract. Dedicated monthly teams are billed monthly on hours worked.
Do you offer maintenance after launch?
Yes. After the free warranty period set in the contract (1 month by default), you can continue with a monthly operation contract.
