Software for
the second user.
Every product now has two users: the people who use it and the AI working for them.
Before the AI boom, I wrote software for people. Now every product has a second user: AI, working for them. More than once I looked up what a used tractor costs. Curiosity won. I kept what twenty years taught me about shipping software that works, rebuilt the rest for both users, and started all4.
- Founded in New York, 2026
- Made for people and AI
What we build
Software for the new world,
for people and AI.
Exploring the new world
AI changed what software is for. We study that new ground, question by question, and build to find out.
Two users by design
Every product gets clear interfaces for people and structured access for AI: APIs, tool definitions and documentation machines can read.
Prototypes you can try
What we learn becomes small, working things first. The ones that hold up grow into products.
Where we are
Early.
On purpose.
all4 is a new studio. The first products are in the making and will appear here as soon as they are usable.
There is nothing to download yet, and no roadmap promises. When something is real, it will be on this page.
