Verified seller intelligence for buyers who've been burned by bad data before.

TheSellersIndex delivers verified Amazon seller intelligence with data depth no competitor offers.

The Amazon seller data market is broken. On one side: cheap scraped lists at pennies per lead. High volume, high bounce rates, minimal verification. You're paying to clean data, not use it.

On the other side: bespoke research at £3-10+ per lead. Accurate, but slow and expensive. Fine for enterprise, impossible for agencies.

We built TheSellersIndex to fill the gap.

Our verification pipeline checks every record against company registries, validates every email for deliverability, and enriches every seller with context you can actually use in outreach. Four data fields — VAT number, marketplaces, base country, and seller summary — are unique to us. No other provider offers them.

The result: amazon leads that convert because they're accurate, current, and complete. No record older than 30 days. Every email verified before delivery. Intelligence, not just contacts.
