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.

Sound familiar?
It usually starts one of two ways.
A · On your own
You have an idea. And no idea where to start.
You've carried it around for months. Notes, a deck, maybe a first sketch. But the tech feels like another language. And a whole team is out of reach.
See how we'd start →B · Inside a company
There's an opportunity. But no team to build it.
The customer need is real and there's budget. But IT is booked, hiring is slow, and a big agency brings a lot of machinery before anything is proven.
For companies →Either way, we take it from here. One part, or all the way to a live venture.
From idea to working venture
Four questions. One path.
We work out the business, shape the product and brand, build it and get it into the market.

Customer · business model · offer · price
02 · What should it become?
Brand · product · UX · customer journey
03 · How does it actually work?
Frontend · backend · payments · admin · automation
04 · How does it get into the market?
Launch · analytics · search · customer acquisition

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.
