A shared lead costs a fraction of an exclusive one. That single fact drives most purchasing decisions — and it is the wrong number to optimize.
The math that matters is cost-per-close, not cost-per-lead. An exclusive lead runs 2 to 4 times the price of a shared one, but closes 15 to 30% higher, because there is no second buyer racing you to the same contact. A shared lead arrives with a built-in competitor: you and several strangers are calling the same person, at the same time, about the same need.
Worked example
Say a shared lead costs $30 and closes at 8%. An exclusive lead in the same niche costs $90 and closes at 24%.
- Shared: $30 ÷ 0.08 = **$375 per closed deal** - Exclusive: $90 ÷ 0.24 = **$375 per closed deal**
Same cost per close — but the exclusive buyer got there with a quarter of the calls, a fraction of the sales time, and a customer who was not comparing them to three competitors on price. At scale, exclusive wins on every metric except the one on the invoice.
Where shared still makes sense
Blended models are the common industry pattern for a reason. In verticals where exclusivity is not decisive, a capped-shared arrangement — a hard ceiling of two buyers, never five — recovers most of the economics without the shared-marketplace free-for-all.
The marketplaces are cracking
This is live, not theoretical. In home services, Angi's own service-request volume fell over 23% year-over-year while per-lead pricing rose, and 62% of contractors now name lead generation as their single biggest business challenge. The shared model is getting worse for buyers, not better — which is why exclusive, with real follow-up behind it, is where the market is moving.
