Challenge
Someone who understands a field better than most wants to sell what they know. A plain subscription does not fit: part of the audience will pay monthly, part will take one item and leave, and the most cautious will pay only when the call worked out.
Three pricing models in one product means three ways of counting money, and all three have to meet on a single balance.
Solution
The platform separated two things: the expert's published call, and the right of access to it.
A single purchase opens one item, a monthly subscription opens everything published within the paid period, and payment for results is calculated after the fact. The last one took the most work: the starting state has to be recorded, the outcome waited for, and the share computed with no way to recalculate it afterwards.
Architecture and implementation
What sits inside:
· an expert profile with a public history of published calls
· publication with the time of publishing recorded
· three pricing models settled on one balance
· a share-of-result calculation over immutable records
· access tied to the payment rather than to the expert's account
Payouts to the expert and reporting by subscriber are handled separately.
Result
The platform launched in 2021 and has not been developed since.
The most portable part of it is the share-of-result calculation. The same mechanics are needed by affiliate programmes, referral networks, and any product where the performer earns a share instead of a fixed fee.
