data selling platform

a marketplace where people can sell their personal data directly to companies that want it — instead of having it harvested by platforms without consent or compensation. the framing is flipping the current ad-tech model: right now companies take your data implicitly as the price of using free services. this would make it an explicit, consensual, paid transaction.

the hard problems are: (1) what data is actually valuable enough that companies would pay for it directly — probably behavioral patterns, purchase history, health signals, demographic + psychographic profiles; (2) pricing — how do you set a market price for a person's browsing history; (3) aggregation — individual data is worth little, but if you can aggregate across thousands of consenting users into a dataset, the value goes up dramatically. the platform would need to solve both the individual-facing UX and the buyer-facing data product side.
