Looking for a UI/UX Designer Co-Founder

Hi everyone, I’m Moritz, a founder from Germany. I’m looking for a UI/UX designer who might be interested in becoming a co-founder.

I started my first company at age 15 and ran it until 2018. It was a bootstrapped B2C business selling digital goods that grew to about €1.2M in annual revenue and 80,000+ customers before I exited. Since then I’ve been building SaaS products and experimenting with new ideas. In 2023 I also received a €12,000 entrepreneurship scholarship from the German state NRW. Right now I’m working on two projects with a developer that already generate some revenue: fastpal.com and hofmannmoritz.com.

I’m currently looking for someone to start with a smaller side/weekend project first. The idea is an AI powered bookkeeping wrapper where founders simply chat with a Telegram bot to submit receipts and notes, instead of dealing with folders and spreadsheets. I already built a rough first version and I would personally pay for something like this. Over time it could expand into a broader finance assistant with budgeting and automation features.

The technical side is mostly covered. What I’m looking for is someone who enjoys thinking about product experience and design from the beginning. Someone who likes questions like how to make finance tools feel simple and calm instead of stressful, and how chat based interfaces with AI agents should actually work in a product.

Equity would be based on the Pie Slicer model by Mike Moyer where everyone logs time and money invested and final equity is fixed once the company can pay founder salaries. It’s a flexible system that tends to feel fair in early stage startups.

I’m mainly looking for someone who likes B2B products, is curious about AI tools, and wants to build something long term together. Personal fit matters to me more than a perfect resume.

If this sounds interesting, feel free to message me or share a portfolio.
