I have developed an MVP for a lead management business. The idea is simple;
1. Advertise online about a service; pet insurance, waste service, synthetic turf etc
2. Get the user to agree to a TOS about letting our service pass on the details to a third party.
3. Business get notifications about the fresh lead in their area and they purchase the lead in 1 simple step (It really is that simple and works wonderfully)
The idea is that we would move into less saturated markets at first to prove this model works then move into more profitable markets.
