Building now · One company at a time
Cube builds AI-native startups.
A self-funded venture studio. We build AI-native companies — ours, and yours.
Not a fund.
Not an agency.
The person who builds is the person who decides.
What we launch, we own. What we build with you, you own.
Every company is AI-native by design, not retrofitted.
Every company gets full attention — one at a time.
Where this goes
A portfolio of AI-native companies. Built one at a time, each standing on its own before the next begins.
Not a bigger studio. A longer list.
