About the show
Identical twins Marc and Lucas Leisner love building startups, but their curiosity doesn't stop at business. On The Twin Project they chase whatever is scratching their itch right now — AI, e-commerce, health, mental health, physical health, productivity, self-improvement, biology and beyond. They talk to experts, operators and founders to find out what they actually know. If you go to a restaurant and start counting tables to see how much money it makes, you'll feel right at home.

What we cover
We follow whatever is scratching our itch. That means one episode might dive into a new AI model, the next into sleep, nutrition or longevity, and the one after that into the economics of a restaurant down the street.
- AI, agents and the future of work.
- Startups, e-commerce and the real work of selling.
- Mental health, physical health and human performance.
- Productivity, habits and self-improvement.
- Biology, longevity and how the body actually works.
- Founder stories — the wins, lawsuits and parts nobody posts.
