Choose what to get done
Compute self-employment tax and quarterly estimated payments for a supplied tax year
You get your self-employment tax for the supplied net earnings plus the four equal quarterly estimated payments, computed for the tax-year rates and thresholds you provide.
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 break-even sales change for a price change
You get the minimum percent (and unit) sales-volume change at which a proposed price change leaves total profit contribution unchanged.
Compute the dilution impact of a pre-money option pool top-up
A function that computes the effective (pool-adjusted) price per share and the share of dilution borne by existing holders when a new option pool is created on a pre-money basis.
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.
Core-capability gap register
A structured register comparing required capabilities to current capabilities, flagging each gap with a fill strategy.
Customer lifetime value (simple and discounted)
The customer lifetime in years, the simple LTV, and the discount-adjusted LTV you can put against CAC.
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.
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.
