Compute Default Alive or Default Dead
A pure function that, given current cash, monthly expenses, monthly revenue, and monthly revenue growth rate, returns whether the company reaches profitability before cash runs out (default alive) or not (default dead), the crossover month, and the lowest cash point.
Compute Founder Personal Runway and Go-Full-Time Verdict
A bootstrapping founder learns how many months of personal runway they have and whether it clears the book's full-time-go thresholds, so they can decide whether to quit their job now or stay part-time.
Compute New-Hire Equity Grant by Hire Number
A pure function that returns the equity-grant percentage for the Nth early hire by interpolating between configurable anchor grants (default 1.5% for hire #1, 0.25% for hire #20), per the YC early-hire equity rule of thumb.
Compute Raise Amount and Implied Valuation from Inflection Point
A single headline raise number, the implied post-money valuation range, the investor ownership range it implies, and a flag for whether the ask sits inside the track-record-appropriate band, so the founder can answer 'how much are you raising?' with one defensible figure.
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.
Demand-gen lead-stage definition register
The buyer gets a register where each required lead stage (e.g. MCL, MEL, MQL, SQL) has a definition, a funnel phase, an owning team, an entry criterion, and a lead-score threshold, with thresholds increasing down the funnel.
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.
