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.
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.
Cold-outreach sequence with timed follow-ups
A ready-to-load multi-step sequence: A/B subject variants per email, one clear call to action, send-day spacing that moves forward, and only declared personalization tokens.
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.
Competitor-informed SEO content brief
A complete content brief: primary + long-tail keywords, an H2/H3 outline, must-cover subtopics, a word-count band, link slots, and an on-page checklist.
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 economic value to the customer (EVE) and the viable price range
You get the total economic value to the customer (EVE) and the viable price range (ceiling and floor) for one product in one customer segment, built up from a next-best-alternative reference price and a set of signed monetary value-driver deltas.
