WealthTech & HealthTech venture studioBaar, Switzerland
You have the market. We build the product and carry the cost until it earns.
No fee and no equity. Once you reach $25K MRR we take 6% of revenue until we've been paid 2.5× the build value you signed. Then it stops, and the business is yours alone.
What we build
Two sectors. That is the list.
We build in regulated markets where the buyer is cautious and the product has to survive scrutiny. That narrows what we take on, and it is the reason we are quick inside it.
WealthTech
Private banks, family offices, wealth managers, platforms
Client portals, advisor tooling, onboarding and suitability flows, alternatives access. Built for people who will be asked to justify every screen to a compliance officer.
HealthTech
Longevity, wellbeing, care providers, employers
Assessment and programme tooling, patient and member experiences, clinician workflows. Built for products that hold sensitive data and have to earn trust before they earn revenue.
Who this is for
- You have deep domain expertise in wealth or health, and you already know the buyers
- You can sell. The gap is the product, not the pipeline
- You want to keep your equity for the people who fund your growth later
- You want a partner whose upside depends on your revenue, not your budget
Who we turn down
- You have an idea but no route to a buyer yet
- You want passive investment without running the business day to day
- You want a fixed-scope build with no ongoing relationship. That is an agency, and we are happy to recommend one
We fund every build from our own balance sheet, so we take on a small number of operators at a time.
Why it works this way
Our return depends on your revenue
Which means we are wrong about the same things you are wrong about, and at the same time.
We carry the build risk
No fee, no retainer, no invoices. Windmill funds design and engineering through to production. If the product never sells, you owe us nothing.
You keep the company
0% equity by default. You stay CEO, your cap table stays clean, and your code and IP are yours from the first commit.
The share ends
6% of revenue from $25K MRR, until we have been paid 2.5× the build value we signed with you. Then it is over. Not reduced, over.
The whole deal
Four numbers, and nothing behind them
- Upfront
- $0
- No fee, no retainer, no invoices during the build
- Equity
- 0%
- You keep the company and the cap table
- Of revenue
- 6%
- Starting only once you reach $25K MRR
- Then it ends
- 2.5×
- Capped at 2.5× the build value, or 48 months of payments
How it goes
From first conversation to finished
- 01
We qualify each other
A conversation about your market, your buyers and your route to revenue. We say no often, and we say it quickly.
- 02
We scope and price it
Two weeks, funded by us, to agree exactly what gets built and what it is worth. You sign that figure before anything is built.
- 03
We build it
Design through production, paid for entirely by Windmill. You sell into your market while we ship.
- 04
You repay from revenue, then you're done
6% from $25K MRR until we reach 2.5× the build value. Then the share ends and the business is yours alone.
