Classify Burn-Rate Danger Level
A pure function that converts monthly burn and cash on hand into months of runway and a danger classification using runway-month thresholds, per Altman's rule that burn is only scary when runway is short.
Clean-code smell scorecard for a method
A per-method clean-code smell scorecard: which thresholds each method exceeds (long method, too many arguments, deep nesting, and more), a 0-100 score, and a pass/warn/fail verdict.
Compute Amdahl's-Law parallel speedup and efficiency
A pure function that, given a parallelizable fraction and processor count, returns Amdahl's-Law speedup, efficiency, and the asymptotic ceiling, graded on hidden numeric cases.
Compute an add-on price as percent-of-base with floor and cap
I give a base ACV, a percentage, a floor and a cap, and get the add-on price = clamp(pct * baseACV, floor, cap), so the add-on scales with customer size but stays bounded.
Compute Break-Even Point and Margin of Safety
A founder learns the exact unit and revenue break-even point so they can judge whether the required sales volume is achievable before fixed costs are recovered.
Compute Cofounder vs Employee Cash-and-Equity Cost
A side-by-side of cash burned and equity given for filling a role as a cofounder versus an employee over the runway window, plus the company valuation at which the cofounder's extra equity costs more than the cash saved, so the founder can decide which is economically cheaper.
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.
