Hi John,

Just following up on the proposal I sent over. The Q2 projections are looking strong across all three segments — I’d recommend we greenlight Phase 2 and loop in the design team this week.

Happy to walk through the numbers in more detail if helpful.

Best, Noah

With Ditto

Write a product brief for our onboarding flow redesign. We’re a B2B SaaS platform with 12k users — current activation rate is 34%, and we’re targeting 50%. The project is sponsored by our VP of Product and ships in Q3.

Cover the problem statement, proposed solution, user stories for three personas (new user, team admin, enterprise buyer), success metrics, and a phased rollout plan. Keep it under 2 pages, use our existing OKR framework, and prioritize self-serve users over enterprise in Phase 1.
