For startups and founders
Get your first health product in front of real users.
You have an idea and a limited budget. We help you test it quickly with a fixed-price prototype, then build the full app with the same team.
Where to start
Health App Readiness Review
Built your first version with Lovable, Cursor, Replit, or another AI tool? We review it, fix the security gaps, and get it ready for real patients and investor questions.
The problem
A first product is a big bet.
Most founders we talk to run into the same few problems.
- It is hard to know what to build firstThere are a hundred features you could build. Picking the wrong ones uses up time and money before anyone has tried the app.
- Big quotes come before any proofA large quote for a full app, before anything has been tested, puts all the risk on you.
- Health apps need extra carePeople share personal details with health and wellness apps. Privacy has to be planned from the start, not added later.

Questions
Questions founders ask
How much does a prototype cost?
Prototypes are a fixed price, starting at $15,000. You'll know the price before we start, and it only changes if you change what the prototype needs to do.
Do I own the code?
Yes. Once the project is paid for, you own the code, designs, and app store listings we create for you.
Can you take over an app another team built?
Yes. We often pick up projects from other developers. We review the code first and tell you plainly what we would keep, fix, or rebuild.
Do you build for iOS and Android at the same time?
Usually, yes. Many apps work well on one shared codebase for both, which keeps updates simpler. Some need separate native code for specific features. We explain the trade-offs before we start.
What if my app handles health data?
Before we write code, we map what data the app collects, where it lives, and who can see it. Then we build to the rules that apply to you.
