The open beta & founding cohort
August is the open beta. October 1 is launch day.
T2D3 OS opens August 1 in open beta: the full product, feature-complete, hardening with you through September. Sign up with a card, pay no base fee until the official launch on October 1 — during beta the only thing you can pay for is extra AI credits beyond what your plan includes. We remind you before billing starts, and you can cancel anytime.
Go further: what founding members get
- The founding price, locked for good — the launch price never goes up on you, for as long as you stay
- The whole beta free — the complete OS from day one, $0 base fee until October 1, nothing held back
- The founder onboarding session — join a live cohort session with Stijn; attending extends your free run past launch, adds a founding AI-credit bundle, and marks you a Founding Member
- Three invites of your own — bring in the operators you rate
- A direct line — beta feedback goes straight to the team building the product
