A sample of what this play produces. Your result is generated for your inputs.
| Id | Fit Stage | Evidence Type | Description |
|---|---|---|---|
| PS-1 | problem-solution | interview | Founder-user interviews with solo and early-stage founders during the soft launch: the recurring pain named is re-explaining the business in every AI session and carrying outputs somewhere by hand before they go stale, matching the problem STUD targets. |
| PS-2 | problem-solution | observation | Dogfood observation: STUD runs its own strategy, pricing, and legal work through its plays. A fact stated once in the workspace flows into every later run, removing the restate-the-business step the blank prompt box forces. |
| PS-3 | problem-solution | experiment | Catalog experiment: replacing the blank prompt with a ready-made play plus a short intake that fills itself from workspace facts; deliverables land structured and pass an acceptance check before they count, versus untracked chat output. |
| PM-1 | product-market | analytics | Catalog usage during the pre-revenue soft launch: 265 plays across 14 playbooks live and settling, with plays priced 250 to 1,000 credits ($10 to $40) per run; most plays cost 500 credits ($20). |
| PM-2 | product-market | survey | Waitlist intent survey (illustrative launch scenario): 200 launch signups, 40 activated buyers in month 1 (bought a first pack and ran a play), 25 retained at month 3, about 1.25 plays per active buyer per month at the typical 500-credit price. |
| BM-1 | business-model | sales-data | Published pack structure at launch (credits v3): prepaid credit packs at $20 (500 credits), $40 (1,000 plus 50 bonus), $100 (2,500 plus 250 bonus), $200 (5,000 plus 750 bonus), with annual prepay packs at $240 and $720; purchased credits never expire and are spent only on an accepted run; illustrative first-pack mix 60:25:10:5, average first pack $42. |
| BM-2 | business-model | analytics | Unit-economics model (estimated): gross margin modeled at 85 to 90 percent at launch pack prices with a $0.04 credit peg; illustrative content-led CAC about $40 against about $300 average annual revenue per account (about $25 a month in packs). |
