Mobile app development
We design it, build it and publish it, from a single codebase for both platforms. Payments, push, analytics included. You deal with one point of contact, and the price is fixed before the first line of code.

Wellness · 7 years in production
The ritual app that competes with Calm without their budget: generated meditations, in-app live sessions, integrated payments. It runs on €500 of infrastructure a month.
Productivity · featured by Zapier
A gamified to-do list, listed by Zapier among the best AI productivity tools, alongside Asana.
Social network · 60 days
A complete social network shipped in 60 days: feed, accounts, AI, and a paywall from launch day.
Social · brand
An app to manage your social presence, from design all the way to publishing on the stores.
We built a complete social network in 60 days. Feed, auth, AI, paywall: everything. What blew me away is that the architecture was clean from day 1. No technical debt, ready to scale.
Noé Charmont CEO & co-founder, Strive When we have an idea on Monday, it's live on Friday. In 7 years of working together, he built technical foundations so solid that the app still runs on €500 a month.
Vivien Ducros CEO & co-founder, Evolum How we hold 1 week
A typical agency quotes 4 to 6 months and bills iOS and Android as two projects. Here, one Flutter codebase serves both stores from day 1, and you talk directly to the people building. You get a 30-minute scoping call, then silence until launch.
DAY 1 · MORNING
30 minutes to settle what ships in V1. Store accounts, branding, scope locked. You leave with a fixed price and a date: 7 days.
DAY 1-2
Accounts, navigation, real data, your visual identity. The app installs on your phone by day 1.
DAY 3-5
Payments, content, notifications, back-office. Every feature is testable immediately. We prioritize what pays off fastest.
DAY 6-7
Testing on real devices, store listings optimized, submission to Apple & Google. You get the app live, with its documentation.
If there's no build on your phone by day 1, we stop and you owe nothing.

The packages
MVP makes the product exist, GoToMarket makes it sell, GoToTheMoon brings the demand. The figure is set at kickoff against your scope, and it's written down before the first line of code.
MVP

An app that holds up in production.
GoToMarket

Set at kickoff + monthly
A machine that fills the app.
The same screen costs three times less when your data already exists, and three times more when an ERP has to be wired in. We settle the scope in 30 minutes, then the figure is written down and doesn't move.
The package covers the build. Recurring costs are announced at kickoff and paid directly by you.
What you own
One Flutter codebase for iOS and Android instead of two teams, and nobody between you and the people building. Plus: you have my WhatsApp, so no waiting.
Scope. We cut hard at kickoff: the feature that creates the value goes first, the rest waits for the next version.
Evolum has been running for 7 years with over 100,000 users and 92% crash-free sessions, on €500 of infrastructure a month. An architecture set up properly on day one is what lets you add features fast later.
It's the simplest case. You bring the business and the customers. Every week, we show you the app for 45 minutes and you tell us what rings true.
Yes for the build. The only extras are the recurring costs listed above (store accounts, hosting), paid directly by you, with no margin from us.
Often, yes. We start with a short audit: what can be saved, what must be rewritten, and what each option costs.
Either a clean handover, with documentation and training, so you take over or hire. Or Build Partner: we stay on your product monthly to keep shipping.
A deposit at kickoff, the balance when the app is published on the stores.
The scoping call
30 minutes to decide what ships first. You leave with a firm figure and a launch date, even if we don't work together.
