Choose what to get done
Compute required ownership and present value from a target exit
A function that, from a projected exit value, holding period, and target return, computes the required present ownership fraction and the implied present value of the position.
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 destinations (communities, forums, groups, syndication spots) to post your content to, each row with a destination name, a well-formed link, an accepted content format, and a posting cadence, spread across at least your minimum of distinct 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.
Customer profile
A ranked customer profile for one segment: the jobs your customer is trying to get done, the pains in their way, and the gains they want, every entry carrying a high, medium, or low rank so the profile states priorities instead of listing everything equally.
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.
