So if your target market is the brokers, the trick is providing value to them. That means more commissions, or more profit per commission. There might be a market for painkillers and making it less stressful, but that will be a much smaller market than getting a piece of that commission cash flow.
And for pricing, either you charge a LOT for service, or you get paid per commission as a percentage, which puts you in the land of state-by-state regulatory and is hard.
To me, this feels a lot more like the enterprise software market than the consumer app markets that seem to attract so many startups. I keep seeing people talk about a B2C approach, and I just don't see how you make a lot of money at that.
