Get to know ZB Stack.
What is ZB Stack?
The platform that builds your software and keeps improving it. You own all of it.
What is CORA?
Continuous Observation, Recursive Advancement — the RSI Agent inside ZB Stack. It watches how your product is used, builds the fix, and learns from what happens. Ask it for something, or let it come to you.
What is an RSI Agent?
An AI agent that doesn’t just do the work — it gets better at it. An RSI Agent learns from real outcomes, improves how it works, and starts every version from what the last one learned. CORA is the RSI Agent for software.
Who is behind ZB Stack?
A small team out of Ide8 Co-Foundry, which builds companies rather than investing in them. More about us →
Does CORA learn from other people’s software?
Patterns, never data. Your customers, numbers and records stay in your system and go nowhere else.
Does CORA change my software without me?
Only what you’ve said it can ship alone. Pricing, policy, permissions and customer data always wait for a person.
What does “improves itself” actually mean?
A change goes live to some of your customers and stays only if it did better than what was there. Until then it’s a candidate, not an improvement.
How is CORA different from a coding agent?
A coding agent waits to be told what to build. CORA finds what’s worth fixing, builds it, ships it with your approval, and measures what happened.
Can ZB Stack upgrade what I already have?
Yes — a prototype, a store, or a system you’ve run for years. What works stays; the improving starts from there.
Why do you take only a few customers at a time?
Every system CORA works on teaches it something the next one starts out knowing. We keep the circle small so the lessons are true.
Do we need an engineering or DevOps team?
No — building and running are provided. Engineers you already have can direct it, review it, or own parts of the codebase.
Where does it run?
On ZB Cloud — a major cloud, a GPU data center, or your own servers. You choose the country your data lives in.
Who owns the product, code, and data?
You do. Always.
How is ZB Stack packaged?
A subscription, priced on the size of your system, how much CORA does on its own, and the uptime you need. You’ll have the number before you commit to anything. Apply →
Can I see it working?
Yes. Watch CORA work →
