Hi, I'm Jonas.
I look for opportunities and ideas worth building, and build the startups myself. Clienzo is the first.
what I do
I look for problems worth solving and build startups around them myself — from the first line of code to the pricing page, the support inbox and the platform reviews nobody warns you about.
The first is Clienzo, a social media scheduler for founders, freelancers and small agencies. It will not be the last: I keep a list of opportunities, and I write about the ones I look at — including the ones I decide not to build, and why.
I'm better at building than at selling, so I'm learning product marketing the only way I know: by trying things on a real product and writing down what happened. Some of it works. A lot of it does not. Both end up here.
what I write about
- Building SaaSArchitecture, integrations and the unglamorous parts: billing, email, reviews by platforms.
- Product and growthPositioning, pricing, and getting a small product in front of the right people.
- AI and automationUsing AI to build faster, and building products that AI assistants can use.
- IdeasOpportunities I am looking at, and the ones I passed on, with the reasons.
- LessonsDecisions I made, why, and how they turned out — with dates, in the build log.
how I work here
No invented numbers. If I share revenue, users or results, they will be real and dated; until then, you will not see any. Tools on this site are labelled with how I actually know them, and there are no affiliate links unless a page says so.
