Margin-on-efficacy
Margin-on-efficacy is a commercial pattern where the provider's earnings are priced against the improvement users get when they incorporate the offering into something they're trying to do. The user brings the pursuit, the energy, and the destination; the provider supplies something that makes the pursuit go better, whether by getting there faster or by reaching places the user couldn't have reached alone. The capture attaches to that gap, not to the offering itself.
Definition
A commercial pattern where providers earn margin on user route efficacy improvement — the delta between the user's baseline route efficacy (without the offering) and their route efficacy when integrating the offering's affordances into their pursuit.
Margin attaches to the delta
The user shows up with intent and energy already. The pursuit is theirs, in service of their own sought state, and the provider can't capture value on the pursuit itself. The provider supplies route-efficacious affordances — affordances whose fit aligns with the route the user is traversing. When the user integrates those affordances into their traversal, route efficacy improves above what they could achieve without them.
The improvement is where the margin lives. Affordances are the means; the priced object is the delta itself. The user's baseline route efficacy includes whatever else they could do at each step: pen-and-paper, improvisation, substitute tools, asking a friend, not-doing-it-at-all. The provider's capture is priced against the gap between that baseline and the route efficacy the user achieves with the offering's affordances integrated.
This is what makes the capture honest under mutualism. The user keeps the value of the pursuit itself; the provider's margin is on improvement the user wouldn't have gotten without the offering.
Forms of efficacy improvement
Two common readings:
- Faster — the user reaches the same sought state more quickly. They could have gotten there on their own; the offering shortens the path.
- Further — sought states that weren't reachable without the offering become reachable. The user's route efficacy extends to outcome-profiles previously out of reach.
These don't exhaust the category. Affordances can also support categorically different outcome-profiles — a mousetrap and mouse-chasing both resolve a mouse-problem intent through different routes with different resulting state properties. Faster and further are particular readings along common axes (rate, coverage); other axes exist.
Subscription binds this continuously
Subscription billing requires continuous route-efficacy delivery. The user pays recurringly for ongoing improvement, and the offering has to keep providing it over the life of the subscription or the capture stops. In self-serve SaaS, this makes ongoing match-quality the business model's central commitment — the apparatus that detects, qualifies, and serves intent is what runs the business model.
Example
A small business owner wants accurate, on-time taxes (the sought state). Her baseline options for reaching it: spreadsheets, paper receipts and a calculator, hiring a bookkeeper, working from memory. Each delivers some route efficacy toward filing.
QuickBooks provides affordances — bank sync, automatic categorization, tax-ready exports — that the owner integrates into the pursuit. Her route efficacy improves: faster filing with fewer errors, and reach to outcome-profiles like real-time profitability views or audit-ready records that pen-and-paper couldn't reliably produce. QuickBooks captures margin on that delta. As a subscription, the capture is priced against ongoing improvement — every month the owner is still in pursuit, the offering has to keep delivering.
