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.
Classify Capital Character: Patient/Impatient for Growth vs Profit
A deterministic function mapping a venture's funding terms onto Christensen's two-axis capital-character model and returning whether the capital is good or bad for a new-market disruption, with the quadrant label.
Classify Startup Growth-Engine Fit (Viral / Sticky / Paid)
A founder receives a structured engine-fit assessment that pins each of the three Lean-Startup growth engines to a pass/fail gate on its driving metric and names the recommended primary engine.
Classify whether to publish prices using the market 2x2
I give market size and homogeneity (with thresholds) and get the quadrant plus the publish-on-website recommendation, matching the book's transparency 2x2.
Compare gig-platform fees and net earnings
For each platform entry: netEarnings = round(grossEarnings * (1 - feeRatePct/100), 2); feeAmount = round(grossEarnings * feeRatePct/100, 2); winner flag on the highest-net platform.
Compute a convertible-note / pre-money SAFE conversion price (cap vs discount) and simple round dilution
You get the conversion price per share for a PRE-money convertible note or pre-money SAFE (the lower of the cap-implied and discount-implied price), the shares it converts into, the round's post-money valuation, and the new lead investor's post-money ownership percentage.
Compute a liquidation-preference waterfall (multiple, participating vs non, cap)
You get each preferred investor's exit payout and the common-shareholder (founder and employee) residual for a given exit value, computed from each investor's invested amount, preference multiple, participating-or-not, participation cap, and as-converted ownership; payouts always sum exactly to the exit.
Compute a proportional token allocation from contribution scores
Each contributor's token allocation = round(contributionScore / sumAllScores * totalPool, 2), and the sum of all allocations equals totalPool within tolerance.
Compute a weighted-average anti-dilution conversion price
A function that applies the broad-based weighted-average anti-dilution formula to produce the adjusted conversion price for an earlier preferred series after a dilutive financing.
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.
