Software for product teams that already have a sketch

You have a flow, a store listing, or an API contract in your head. You want a studio that ships with you, not an agency that spends six weeks discovering and then sends a deck.

StepQuests is web plus mobile, five languages, own tours and Haarlem Uitjes. Weekboodschappen is a SaaS-shaped loop: accounts, plan, list, come back next week. Red Flags is multiplayer, lobby to a round in under two minutes as a product goal. That is the kind of work.

We work with someone in-house when they exist. We work alone when they do not. The stack follows the product: Next.js, Expo, Postgres, Netlify, native where it has to. The SaaS service page says what a product with accounts includes. The software-fit quiz helps when web, app, or something else is still open.

Send the flow, not the pitch deck

A link, a sketch, what sprint one should put on a phone or in the browser. Mail hello@yonts.com or use the form.

Product teams

Can you work in our repo?
Yes, if access is in place. We can also start a separate repo and hand it over later. We agree that before the first sprint.
Do you only do greenfield?
No. Existing Next.js or Expo apps are fine if the code is followable. If the base is rotten, we say so in week one, with the effect on time.
Who handles store reviews and crashes?
On a retainer: us, until we hand over. A one-off build without upkeep is also possible. Then the quote says where responsibility stops.
