You have an ambitious idea or prototype, but no clear method for testing if it should become a business.
For ideas, prototypes, and founders before traction
Get support before you have traction
The STARTPLATZ Open Incubator – powered by cozama gives committed founders a structured way to validate, de-risk, and build their idea before the ecosystem knows what to make of it - at their own pace, without giving up equity.
A fair shot
Input matters before outcomes exist.
Bring the idea. We help you find the next useful step.

The gap
Most support starts after you have already proven too much.
Early-stage founders need the most guidance before product-market fit, revenue, or a complete team exists. That is also when many programmes become hard to access.
You get rejected because you are too early, solo, part-time, or still learning what evidence matters.
You are surrounded by advice, but still alone with the question: what should I do next?
The plan
Three moves to make progress visible.
You do not need traction to start. You need a real problem worth testing, honest feedback, and a rhythm that turns effort into evidence.
Start your first cycle
Join any time, define the idea clearly, name the customer problem, and choose what must be learned next.
Get structured support
Use mentoring, office hours, and practical frameworks to avoid expensive early mistakes.
Unlock what you need
Progress earns access to community, experts, perks, visibility, and investor pathways when the timing is right.
What changes
You stop guessing alone and start building from evidence.
Open Incubator is open, but demanding. We take your ambition seriously early, then help you earn more support through visible effort and learning.
Clarity
Know who you are building for, what problem matters, and which assumptions need testing first.
Focus
Work on priorities that move the idea forward instead of chasing every possible feature or opinion.
Foundation
Build systems, habits, and decision quality before growth makes every mistake more expensive.
Community
Stay close to founders, experts, investors, and people who understand the early uncertainty.
Why STARTPLATZ
Experienced founders should open doors earlier.
STARTPLATZ has worked with startups for since 2012. We have seen the patterns that make companies stronger later - and the preventable mistakes that quietly weaken them early.
The Open Incubator exists because a founder can deserve support before an idea is fundable. The point is not to promise success. The point is to help you validate and de-risk with a method.
Simple terms
100 EUR/month, net. No equity. No gatekeeping theatre.
Join when the work becomes serious enough to need structure. Stay as long as the programme helps you make meaningful progress.

Founder outcomes
From insecure curiosity to a sharper next step.
"I learned there is a method to validating an idea - and that signals I read as negative were actually useful evidence."
"The structure helped me keep making progress while turning a personal prototype into something others could want."
"We had no traction yet, but our effort was visible. That gave us a fair shot before anyone else was ready to bet."
Good questions
The honest version.
No. The Open Incubator is designed for the stage before those outcomes exist. You need ambition, commitment, and a willingness to test your idea honestly.
Yes. The programme is flexible by design. You can work at your own pace and unlock support through progress rather than fitting a fixed accelerator profile.
It means we pay attention to the quality of input: learning, execution, focus, and how you deal with roadblocks. Better evidence and effort unlock more relevant support.
Ready when you are
Bring your idea. Leave with a clearer next step.
Join the Open Incubator and start building evidence before the market, investors, or accelerators know what to make of you.
Pick a time for the onboarding conversation. No pitch theatre, just the next useful step.
