The LeadSynth platform shut down in July 2026. We now hand-build verified lead lists. Ask for a free sample

A note from the founder · July 2026

The platform is closed.
The lead shop is open.

In June, Reddit ended the third-party API access our discovery engine was built on. Every tool in this space lost the same ground overnight. We could have kept charging for software that no longer did its job. We shut it down instead: every subscription cancelled, nobody billed again.

What survived is the part that always did the real work, finding businesses that need what you sell and proving it. We do that by hand now, and we sell the results.

What we sell now

For web, SEO & design agencies

Broken-website lists

Businesses whose websites are failing right now: expired SSL, server errors, layouts that collapse on a phone. Every defect is reproduced by hand before the row ships, so you open the conversation holding proof instead of a guess.

For any B2B team

Custom prospect lists

Your ideal customer, your cities. Business name, verified contact, and the specific reason each row made the list. Delivered as a clean CSV within 48 hours.

For founders with no time

Done-for-you outreach

We find the businesses and start the conversations for you, one at a time, at human pace, from our own machine. You step in when someone replies.
