Validated 3-part-tariff block-pricing schedule
I get a 3-part tariff table where each block's overage price exceeds its inferred per-unit price, blocks tile the volume range without gaps/overlap, and inferred unit rates decline with volume.
Van Westendorp acceptable price range
I enter each respondent's four price answers and get back the deterministic Van Westendorp points (PMC, PME, OPP, IPP) on the observed price grid, so I have a defensible acceptable-price band.
Verified prospect list sized to the meeting target
A validated, deduplicated prospect list that stays inside your ICP (industry / role / location / size), carries a reachable contact per row, and is large enough to hit your meeting target.
Viral coefficient and loop-driven user growth
A founder learns their viral K-factor and the cumulative users a seed cohort generates across viral cycles, so they can judge whether the product can grow on the viral engine alone.
Weekly growth-target schedule
A pure function that, given a starting metric value, a weekly growth rate, and a number of weeks, returns the compounded target for each week and the final value, mirroring the YC forward-looking growth graph practice.
Weighted founder idea-selection matrix
A structured decision matrix that rates each candidate idea against weighted virtue criteria, computes the weighted score (SUMPRODUCT of weights and scores) per idea, and ranks them, so founders pick a direction on stated criteria instead of gut feel.
Work-sample interview question bank
A reusable, competency-mapped question bank where each question has a predetermined acceptable answer and red-flag list.
