Choose what to get done
Compute the bill under a linear, 2-part, or 3-part tariff
I give a usage volume and a tariff schedule and get the exact amount owed, with the right block selected and overage applied only above included units.
Compute the 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.
Compute 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.
Content distribution checklist
A deduplicated checklist of real destinations (communities, forums, groups, syndication spots) to post to, each with a well-formed link, an accepted format, and a cadence, spread across enough format types.
Decision-rights and single-threaded-owner register
Every critical decision and deliverable has exactly one named accountable owner, with advisers/consulted/informed parties and an escalation path explicitly recorded, eliminating diffused 'chicken' accountability.
Design a cheap parallel channel-test plan with pass/fail thresholds
I get a parallel channel-test plan where each test has a metric, a small budget, a duration, and a clear pass threshold, so I can run cheap experiments and read the results the same way.
Design a conjoint analysis attribute/level/profile set
I get a runnable conjoint design: an attribute/level grid that respects the 6-7 attribute ceiling and >=2 levels per attribute, plus choice tasks of valid, non-duplicate profiles built only from those levels.
Diagnose the Fatal Pinch
A pure function that classifies a startup against Paul Graham's fatal-pinch definition: default-dead AND slow growth AND not enough time, returning the overall verdict and which of the three conditions are true.
Financing Deal-Stage Tracker
The founder has a complete, sequenced map of the financing process with durations and gating artifacts, anchored to the term-sheet handoff.
Financing-round closing checklist
A structured closing checklist covering each step of a priced round, with status and the minimum-commitment gate enforced.
In-House Build-vs-Buy Tendency Scorer
A founder weighing whether to sell an AI capability as a service gets a 0-6 in-house-tendency score and a build/buy verdict per the book's exact criteria, flagging capabilities customers will just build themselves.
Interview panel coverage plan
A structured interview-loop plan mapping interviewers to competencies, sized per the research, with a dissenter assigned.
