Test your product with real people — before you scale.
One of our most established formats.
UX-Testing is one of the most established formats at Startup Incubator Berlin. Startups present their product, prototype or service to a real audience — and learn within a few hours what works, what confuses people and where users drop off. For visitors, it’s the chance to try exciting products before anyone else, meet the founders in person and help shape real products with honest feedback — in a relaxed Venture Café atmosphere, free of charge and with drinks.

Stop guessing. Start knowing.
With UX-Testing you put your product to the test: interested guests try it on site, work through typical tasks and share their impressions. Instead of building on assumptions, you get solid user feedback — the basis for better products, higher conversion and shorter development cycles.
Whether it’s an early idea or a near-finished product: you watch where people hesitate, what they overlook and what excites them — and take away concrete improvements, instead of debating assumptions in your team. It’s exactly this unvarnished outside view, in an open and relaxed setting, that makes the format so valuable.
Better to learn something small early than watch something big fail late.
The most expensive way to build a startup is to spend months on something that, in the end, nobody really needs.
If you build a product purely on assumptions — „people will surely want this“ — you often only find out months later whether the idea holds up. By then a lot of time, money and energy has gone into features that may miss the real need. This is exactly where the Lean Startup principle by Eric Ries comes in: let reality test your assumptions as early as possible, instead of taking them for granted. It’s not gut feeling that decides, but validated learning — real knowledge about what works and what doesn’t.
The mechanism behind it is a loop you run through as quickly and as often as possible: you build a small, testable version, measure how real people use it, and learn from their behaviour — then carry what you learned into the next round. Every loop makes your next decision a little safer.

UX-Testing is your fastest way through Measure & Learn
You don’t need to set up your own user study to run this loop. UX-Testing is the lowest-threshold way through Measure and Learn: in a single evening you see real user behaviour and get honest feedback on exactly the state you’re in right now — no overhead, no study prep.
In around three hours you go from an open question to solid insights you can actually base your next build on — instead of guessing.
Upcoming dates.
Still have questions?
Who is UX-Testing for?
For academic teams and startups with a product, prototype or service that needs real user validation. You register your startup via the registration form.
How do I register for UX-Testing?
Through the form on the UX-Testing page — that’s where you choose your preferred date. Your registration is only valid once you’ve received a confirmation email from us; the details for the date arrive around two days beforehand.
How finished does my product need to be?
A product, prototype or service is enough — it needs to be testable so real users can work through typical tasks with it. Early stages benefit too: that’s exactly when it shows what confuses people and where they drop off.
I’m not in an SIB programme — can I still have my product tested?
Yes. UX-Testing is open not only to participants of the SIB programmes and the Lean Startup Sprint, but explicitly to external teams as well. Just register via the form with your preferred date.
Does UX-Testing cost anything?
No, the session is completely free for you. We provide the rooms and infrastructure as well as interested guests as testers — you just bring your product.
When do the sessions take place and how long do they last?
The next dates are Thursday, 23 July and Thursday, 27 August 2026, each from 5–8 PM at SIB in CIC Berlin. All details on setup and schedule arrive around two days beforehand.
