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 destinations (communities, forums, groups, syndication spots) to post your content to, each row with a destination name, a well-formed link, an accepted content format, and a posting cadence, spread across at least your minimum of distinct 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 every test names one of the 19 canonical traction channels and carries a metric, a small budget, a duration, and a numeric pass threshold, so I can run several cheap experiments at once and read every result 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, split at the term sheet signing and ending at funds received, with every stage named, owner-assigned, and closed by a gating artifact, and a duration roll-up checked against the cap set at intake.
Financing-round closing checklist
A structured closing checklist that echoes your frozen round stage, close date, and raise amounts, covers every closing step you require (a canonical six-step sequence by default), and enforces the minimum-commitment and wire-sequencing gates arithmetically.
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.
