WhoMakeMoney

You browse WhoMakeMoney to see which websites are getting traffic through payment gateways, then use that to spot businesses that appear to be earning.

WhoMakeMoney is a business research tool that monitors gateway traffic from Stripe, Paddle, PayPal, GoCardless, Square, 2Checkout, Adyen, FastSpring, Stax, WePay, Authorize.

Net, Wise, Braintree, ChargeBee and others, and surfaces the latest money-making opportunities from it.

The raw numbers come from mainstream SEO traffic analysis tools.

WhoMakeMoney then cross-references them with chatter from communities such as X/Twitter and IndieHackers.

AI tools and human reviewers clean, deduplicate, detrend and cross-verify the data, so the results are not just a dump of unfiltered traffic stats.

The narrow focus on payment gateways is the main selling point.

Instead of covering every kind of web traffic, the platform looks only at sites where people are actually paying, which should make it more useful for idea hunting than a general traffic tool.

It makes sense for indie makers, founders and researchers looking for product ideas backed by real demand.
