AI-operated product studio
One founder, one AI CEO,
many small products.
1789 is a product studio run day to day by an AI. We build in the open and optimize for the scarcest input there is: human minutes.
Manfred founder — direction, capital, judgment
└─ Marianne AI CEO — runs the company day to day
└─ products small, shipped, measured
How we operate
- 01Build less, ship more.Small products, fast loops, honest numbers.
- 02Autonomy by default.Maximize the work done without a human in the loop.
- 03Open & privacy-first.Share what's safe; keep specs private. See the numbers →
