From idea to a real app in your hand — for free.
Most agencies sell you slides and quotes. We build first, then let you decide with the real thing.
Tell us the idea
A single 30-minute call. No brief, no deck required — just talk us through what you want to build.
We build the MVP
Within a week our team designs and builds a real, tappable version of your core idea — not a mockup.
Try it on your phone
We install it on your own device. You hold it, tap through it, share it — free. Then decide if we build the rest.
Six steps, from idea to a live app.
A complete, in-house process. Same team from the first sketch to long after launch.

Fair prices, because nothing is outsourced.
Design, development, testing — every part of your app is built by our own team, under one roof, in our Paris studio. No subcontractors, no middlemen, no markup. That's how we keep pricing honest and timelines we can actually hold.
Designers, developers and product managers all on the same team. Nothing subcontracted, nothing lost in handoffs.
You control the scope, you see the price. No hidden fees, no surprise invoices — the fairest rate for the work, full stop.
Fewer hands means fewer delays. We commit to dates up front — and because we own the whole chain, we hold them.

Lumen — Sleep & recovery
We started with a free MVP preview. Two years on, we've shipped 18 releases together, grown the team's roadmap, and kept iterating on retention and performance — as one product team, not a vendor.
"Lissio isn't a supplier executing a plan — they think about what the product should be. The free preview sold us in a day."
Founders who held their app first.
"I'd been quoted €40k by three agencies for a spec I couldn't picture. Lissio just handed me the app. That changed everything."
"The preview took six days. Six. My co-founder and I were tapping through our own product before we'd signed anything."
"No slides, no endless scoping. A real thing in my hand, then a clear plan to ship it. It's the only way I'd start again."
Is the MVP preview really free?
Yes. We build a real, interactive version of your core idea and install it on your phone at no cost. If you decide not to continue, you keep it — no strings.
How long until I can try it?
Usually within a week of our first call. You'll have something tappable in your hand in days, not months.
What do you build?
Native and cross-platform mobile apps (iOS & Android), from first sketch to store launch — and the growth work that follows.
Who do you work with?
Founders, startups and teams — whether you're validating a first MVP or growing an existing product over the long term.
See your app on your phone. Free. This week.
More than an agency — a product partner. We build mobile apps you can try before you pay.
