USE CASE:
Finding more companies like your best customers
Everything below is about finding more companies like your best customers, and about which lookalikes method holds up on a list rather than one record. Mamba Labs writes Apify actors for this kind of work, and Lookalike Company Finder is the one aimed at lookalikes.

What is actually going wrong
Your ten best customers share something that industry and headcount filters miss. Maybe they sell to the same buyers, use the same tools or get compared with the same rivals. Finding more like them is the fastest way to a list that converts. The hard part is turning a feeling about why they fit into a search you can repeat.
Traditional Search Tools
- Ocean.io. A lookalike search built for this job, with filters and exports. Priced as an annual subscription.
- Apollo or ZoomInfo similar companies. A quick start from firmographics. The matches lean on industry and size, so the shared trait you cared about can get lost.
- Look at who they compete with. Read each best customer's comparison pages and review site neighbors, then collect the names. It produces a sharp list. It also takes days.
