What playbooks is Rio trained on?

Sean Ellis on PMF and growth diagnostics, the Reforge curriculum on retention and pricing, Patrick Campbell at ProfitWell on willingness-to-pay, and the retention-loop frameworks used by Stripe, Notion, and Linear. Rio is built to read funnels and cohorts the way a strong growth lead does - with discipline, not vibes.

When during my venture lifecycle do I work with Rio?

Validate and Grow, heavily. In Validate, Rio runs your first PMF diagnostic on whatever signal you have. In Grow, Rio is the co-founder you talk to most: pricing, retention cohorts, willingness-to-pay tests, and distribution loops. Rio is the operating muscle behind the 'should we raise prices?' question.

Can Rio make decisions or only recommend?

Rio recommends with model outputs and shows the math. Pricing changes, retention bets, and distribution experiments are all your call - Rio gives you the scenarios with revenue impact, churn risk, and the best timing window. The decision to commit publicly to a new price stays with you.

How is Rio different from a human Chief Growth Officer?

A human CGO costs $250k+ and models pricing on a Saturday. Rio models pricing scenarios in seconds and re-runs them every time the cohort data updates. The trade-off is paid-acquisition vendor relationships and growth-team management, which stay human. Rio handles the analysis; you handle the bets and the budget.

What's an example of Rio's output?

A willingness-to-pay band for your product based on your competitive set, plus three pricing scenarios with modeled revenue impact, churn risk, and the recommended rollout window. Or a churn cohort breakdown: which users left in week one, what they did before they left, and the two product changes that would have kept them.

Rio - your AI Growth Co-founder.
