The build prompt for a PLG product that grows through no-signup trials, self-serve onboarding, referrals and usage-based upgrade flows.
Built for: SaaS teams building a self-serve growth model
PLG products have no sales team; the product sells itself. That's why the onboarding tour, the shortest path to the 'aha' moment, referral credits and the upgrade screen that appears when users hit a usage limit all have to be designed from day one.
In this prompt, the Growth Architect and Product Manager personas define activation metrics, experimentation infrastructure and pricing tiers; the CTO persona wires them into the architecture with event tracking and feature flags.
Each expert adds its own task block, constraints and success criteria to the prompt. Default selection for PLG Product:
PLG growth plan: activation funnel, aha-moment definition, viral loop / referral mechanics, onboarding checklist, and a weekly experiment list for the first 90 days (hypothesis, metric, success threshold).
Write a flawless PRD. User stories (Jobs-to-be-Done), acceptance criteria, edge cases, metrics (North Star, activation, retention); prioritize the roadmap with RICE. Scope an MVP that ships in 7 days.
Design the system architecture. Edge-first, 100ms p95. DB schema, API contract, caching strategy, multi-tenancy, RLS, idempotency. Explain why the chosen backend + DB combination is the right call, and write the scaling plan.
Landing page copy: hero (headline + subheadline + CTA), 3 benefit blocks, social proof, objection handling, pricing page copy, onboarding email sequence (5 emails), UX microcopy (empty states, errors).
Event tracking plan: North Star and supporting metrics, event/property dictionary, funnel and retention definitions, data warehouse schema, dashboard list, data quality tests.
Preloaded in step 2 of the Studio; change any of the 7 layers.
Every feature appears in the prompt as a "Spec + API + UI + Tests" line.
Sample idea: "A task automation tool for teams that starts free and grows with usage". Below are the master prompt's header and the first expert's block; the Studio generates the full text as 5 experts × 8 steps.

Activation rate, time to value (TTV), weekly active teams and expansion MRR; the prompt asks for the event schema and a dashboard for each of them.
The Monetization Strategist gives a reasoned recommendation based on your product type; on the PLG page the default is freemium plus usage-based upgrades.
