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.
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.
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.
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.
