Build a micro-SaaS
A micro-SaaS is a small online app that does one thing, and that people pay to use. I build yours with you, from the first test to the first payments.
- A first version to test within a few days
- From €6,000 excl. VAT
30-minute call, free and with no commitment.
Why a micro-SaaS
It costs little to build and little to run. You can test it quickly with real customers, then grow it or stop it depending on what you see.
Sigmint creates email signatures, CertSeven prepares the documents for exporting to the United States and Staq organises Valorant teams. I built all three, with their marketing site and online payment.
What I set up
The product
The feature people come for, and nothing more at the start.
Accounts and payments
Sign-up, then a subscription or a one-off payment.
The marketing site
A page that explains the product, written to be found on Google and by AI tools. Most of Sigmint’s visitors arrive through AI tools.
How we go about it
We choose one feature and the person it’s for.
I build the first version, with payment if you want to test selling right away.
You show it to your first users.
We keep what works and move forward in small steps.
The price
- First version of a micro-SaaS
- from €6,000 excl. VAT
That price is about 12 days of work. Tighter budget? Tell me and we’ll make the first version smaller. The exact price is written in the proposal, before we start.
After launch
- Hosting
- from €50 excl. VAT per month
- Maintenance, hosting included
- from €200 excl. VAT per month
- Improvements, hosting and maintenance included
- from €700 excl. VAT per month
I reply within 1 working day. Unused time doesn’t carry over, and outside services, like sending emails or AI, are at your expense. You can stop whenever you want: the code and the accounts stay yours. See the plans in detail

Your questions

What’s the difference between a SaaS and a micro-SaaS?
Size. A micro-SaaS does one thing for a specific audience, and one person can run it.
I’m not technical. Is that a problem?
No. I explain the technical choices in plain words and you test each new version yourself. Your job is to tell me whether it does what you expect.
Who takes care of the server and payments afterwards?
I do if you want, with one of the plans above. You can also take it all over yourself: the code and the accounts are yours.
