How do the terms work?

They're flexible and agreed case by case, usually built around a revenue split. We talk it through on the first call, once we both know the idea is worth building.

What do I need to bring?

Real experience in your industry, a problem people there will pay to solve, and a way to reach the first users: a network, an audience or relationships. We bring everything technical.

Web apps, iOS and Android apps, internal tools and AI features like voice practice, assistants that answer only from trusted sources, and automatic analysis. We pick what the product needs, not what's fashionable.

How fast can a first version ship?

Weeks, not months. We get a working version in front of your first users early, then improve it with them.

Who runs the product after launch?

We do the technical side: hosting, payments, analytics, fixes and new features. You lead the market and stay close to the users.

Ownership is agreed upfront as part of the partnership, in writing, before we build.

What happens after I apply?

We read every application. If it looks like a fit, we book a call to go deeper into the problem and the market. If it isn't, we tell you why.

App partnerships

You know the industry. We build its software.

We partner with genuine experts who see a problem in their field that software should solve. You bring the insight and the access. Our engineers and designers bring the product, and we launch it together.

“Every fault code is a 20-minute treasure hunt. Multiply that by 12 techs.”

What he knows

Techs lose 20 minutes a call hunting for one fault code
Every brand hides its codes in a different PDF manual

The problem

Insiders see the problems first. They rarely get to build the fix.

You know what your industry needs because you've lived it. Turning that into software usually means an agency invoice or a year of hiring.

01
Agencies build what you spec, then leave
You pay upfront, carry all the risk and end up owning code nobody maintains, without the product thinking it needed.
02
Hiring a tech team is a company in itself
A technical co-founder search, salaries and months of runway before anyone uses the first version.
03
The tools in your field miss what you know
Most software in a niche is built by people who never did the job. You can see exactly where it falls short.

How a partnership works

Your insight. Our tech team. One product.

We don't take a brief and walk away. We build, launch and run the product with you, and we share in what it earns.

You bring

Years inside an industry, and a problem in it worth solving
Access: a network, an audience or a seat at the table
The credibility to sell it to people like you
Time to test early versions with real users

We bring

Product strategy and UX
Design and brand
Engineering: web, iOS, Android and AI
Launch: website, launch film and content
Running it: hosting, payments, analytics and updates

Flexible partnership terms, usually built around a revenue split, agreed on the call.

A daily radio-training app for pilots

A practice app that teaches pilots EASA radio phraseology and aviation English in a few minutes a day: a route of lessons laid out on a chart, readback drills, a live 3D circuit where the tower answers what you actually say, and a mascot that keeps the streak alive.

An AI briefing desk for EU public affairs

Built with a Brussels policy analyst: each development on a client's EU files arrives as a tailored, newspaper-style briefing with a short video, cited sources and a human review, plus an assistant that answers only from that briefing's sources.

Who we partner with

A few partnerships at a time. Chosen carefully.

We only take on products we believe in, because we're putting our own team behind them. If it's a fit, we'll tell you on the first call. If it isn't, we'll tell you that too.

A fit

You've done the job, not just studied it
You can name a problem people in your field pay to make go away
You can put it in front of the first users yourself
You're in it for years, not a quick launch

Not what we do

An app built to spec for a fixed fee
An idea with no way to reach its first users
A clone of something that already works

How it works

From insight to a product people use, together

Questions about partnering

Every partnership is different. We talk through yours on a call.

Apply to partner

No. We don't build apps to spec for a fixed fee. We partner with a few experts at a time, put our own team behind the product and share in what it earns.
