StepQuests
Self-guided city walks with stories, quizzes and checkpoints. Web for discovery and booking. The app is the route on the street.

Websites, apps and custom software. We build. You grow.
Yonts builds for ambitious companies across the Netherlands and beyond. Our own apps are live in the store. For your project we work just as hard and just as fast.
What we build
Usually a site, an app, or internal tools, often all three. The rest is on the services pages.
Studio still, generated.
AI automation for the work that comes back every week
Six proven patterns for inbox, quotes, tickets, checks, listings, and the weekly round. We build the run in TypeScript, against an API where we can, with a log line when a step fails. Weekboodschappen and StepQuests already run on it.
Intake desk
Inbound mail or a form: missing pieces listed, a first reply ready to send.
Quote line
From a messy request to a price estimate and a proposal for sprint one, still signed by a person.
Support desk
Tag tickets, stage the standard reply, leave the ugly exception with a person.
Lead checks
A teaser on the page, then email for the report. The same gate as the checks on this site.
Listing scan
App Store and Play copy against the same bar as the listing check. Title, description, screenshots.
Week run
The round that comes back every week: list, status, order. Live example: Weekboodschappen to Picnic.
Talk is cheap. This is live.
Products we built, launched, and still run ourselves. No borrowed logos, no fluff.
Weekboodschappen
Weekly menus and shopping lists for busy households across the Netherlands. The product promise: a first plan in about 3 minutes.
Studio still, generated. This is not a screenshot of the live site.

Red Flags
Friends build ridiculous date profiles and vote on the loudest red flags. Product goal: an active round inside two minutes.

Dirty Seconds
A 30 Seconds-style explain-and-guess game. Starting a round in under a minute is the success bar.

Bar Boef
Public site for a borrelcafé in Haarlem, plus a CMS so the venue can update copy, events and images.

Read the projectHow we work
Something you can tap first
No weeks spent waiting on a concept that stays stuck on a slide. The first sprint ships something you can click, even while the rest is still rough.
Direct line, no queue
You mail the person who also builds, not an account manager passing it along. Our headquarters sits in Haarlem. Our clients sit across the country.
Straight talk on price
Before a sprint starts you get a price estimate. Scope changes get named the moment they appear, with the effect on time or fee.
The tools behind the work
Next.js, TypeScript, React Native, Postgres, Netlify, native iOS and Android. The product picks the stack, not our habits.

Questions we hear a lot
- What does a project cost?
- It depends on size. A marketing site is a different fee than an app with accounts. Sketch what you need in the quote form. We come back with a price estimate.
- Does this work for a small team?
- Yes. Most jobs come from small companies and small product teams. If it fits on one page, that is enough to start.
- How long does it take?
- A focused site can land in weeks. An app or SaaS takes longer, often in two-week sprints. You get the first estimate before we build.
- Do I need developers on my side?
- No. We design, build and ship. If you do have someone in-house, we work with that person.
