Seamless gives you data. MarketBetter gives you data + direction + execution.

Pricing Breakdown​

The credit burn problem: Users report running out of credits within weeks. One Reddit user shared spending $177/month after top-ups when the plan was supposed to be $79. Another calculated they were paying $0.18 per verified contact.
