I have
an idea.
Now what?
Klein & Laut is a founder studio. You bring the idea. We take it from there — from business and brand to a working venture.
A fraction of an agency's resources.Less than hiring your own team.

Two ways this starts.
Independent founders
Your idea. A partner to build it.
- Work out who pays and why.
- Shape the brand and product.
- Build and get it live.
Inside a company
An opportunity. A working first product.
- Test a new business opportunity.
- Work with your business and IT teams.
- Launch before hiring a permanent team.
Either way, we take it from here. One part, or all the way to a live venture.

Who you work with
Klein & Laut is Anna Schwengle.
Hi, I’m Anna. I’ve always been the person who hears “someone should build that” and immediately starts wondering how.
For more than 20 years, I’ve moved between brand, business, product and building. I spent 13 of those years running my own company — which meant everything from products and suppliers to shops, websites, customers, emails and all the decidedly unglamorous bits in between.
That’s probably why Klein & Laut exists. I love taking an early, slightly messy idea, finding the business inside it and turning it into something real people can actually use.
And because I’ve sat on the founder side of the table myself, I care about the whole thing. Not just whether it looks good on a screen — but whether it makes sense, works in real life and is something you can actually run once it’s built.
From idea to working venture.
