Your dev team, without the risk.
We build your SaaS, your web and mobile app, or your AI agent, module by module, from a first version (MVP) to finished product. Each module goes live for your users as soon as it ships, and you pay once it’s validated. If we stop tomorrow, you keep a working product.

Example: a sports coaching marketplace. The need: let people find a coach, book a session and pay for it online.

Coach directory & first contact
What’s deliveredCoach sign-in Coach profiles Simple search Direct contact linkWhat it enablesA coach signs up and builds their profile; a visitor browses the directory with no account and reaches the coach they want over WhatsApp. Booking and payment happen off-platform, between coach and client.
What it validatesDo coaches sign up, do visitors actually reach out? Already a complete product on its own, not a building block waiting for the next module.

Built-in booking & payment
What’s deliveredClient account Slots & booking Online payment Auto confirmationWhat it enablesWhat went through WhatsApp in module 1 now happens on the platform: slot booked online, payment collected, automatic confirmation.
Why not soonerOnly worth building once module 1 brings enough users, or things get stuck: coaches overwhelmed by WhatsApp, clients dropping before they reach out. The numbers from module 1 decide, not a guess.

What our clients say
They did an incredible job: responsive, professional, with a strong sense of initiative and unwavering rigor. They stay alert to the slightest risk or flaw in reasoning that could put the project in trouble. With little experience in the field, I was able to move forward with confidence toward the goals we had set together. I would keep working with them without a second thought.
Translated from French
Dr Léo Joly Founder · Hippocrate At Resilience Care, I had the chance to work with them on a new project built from scratch. They were extremely autonomous and proactive throughout, with a real knack for coming up with clever solutions to the problems we ran into. Their responsiveness was a real asset in moving forward efficiently. Beyond technical skills, they bring a good dose of humor and good spirits, and I recommend them without hesitation.

Julien Paput Head of Engineering · Resilience Care 40–60% less than an agency
Same experienced team, none of the overhead. Every module is scoped and priced with you before any code is written. You know the number before you commit, and pay only as each one ships.
Typically includes ~$18–24k margin, $18k in sales and $18k in project management on top of the build.
Every project is priced with you, module by module. Experienced developers only, no hidden fees, payment per validated module.
If it breaks, we fix it. Free.
We fix any defect at no cost. Every module ships with clean, tested code: that’s what keeps our quality above average and our fixes rare.
Questions founders ask
Do I need a technical background?
No. No spec document or tech vocabulary needed: you describe your idea in your own words, we split it into modules with you, and we explain every choice in plain terms before acting on it.
What kind of products do you build?
SaaS platforms (software used online, often by subscription), web apps, custom software and mobile apps, from MVP to finished product. We also join existing products to build a new module, as we did for Resilience Care’s psychiatry product.
Can you add AI to my product?
Yes. AI agents that handle tasks for your team, an assistant that answers from your own documents, automatic sorting of requests or documents: AI is added like any other module, priced and delivered the same way. We suggest it when it helps your users, not to follow a trend.
What if we stop working together?
You keep everything shipped so far: a tested product, already live, with real users. You only ever paid for the modules you validated.
Who owns the product?
You do. The code, the accounts (hosting, domain name, App Store and Google Play) and the data are in your name. We handle going live and store releases, but you stay in control of everything, even if we stop working together.
How is each module priced?
We scope your project together, in a working session with our team, not an automated quote. We agree on the modules, on what’s essential to launch and what can wait, and each module gets a fixed price before any code is written. You pay per module, on delivery.
How much does the product cost once it’s live?
On top of the modules, a live product has running costs: hosting, domain name, payment, email or AI services. They depend on your number of users and are usually low at launch. We estimate them with you before we start, and you pay the providers directly.
What happens to the features we leave out of the MVP?
Nothing gets thrown away. We list them clearly, with the reason they’re not part of this launch: never “not important,” always “not needed to prove your product works, yet.” You decide if and when they come back, based on what real users show us.
Who writes the code?
Experienced developers only. No juniors billed at expert rates, no outsourcing surprises.
