The best alternatives to ZoomInfo and Apollo.io include BookYourData, Lusha, and Seamless.AI, three B2B contact data providers built around real-time verification, browser-based enrichment, and Chrome extension prospecting.

ZoomInfo centers on enterprise automation and intent data, while Apollo.io centers on outreach sequences and sales engagement.

Three providers most often replace ZoomInfo or Apollo.io in a B2B sales stack: BookYourData, Lusha, and Seamless.AI.

BookYourData filters against 100+ criteria, including industry, job title, seniority, company size, geography, technology stack, and buyer intent. BookYourData is a B2B-only database.

Every exported list carries a 97% deliverability guarantee, and BookYourData refunds credits for any record that falls outside that guarantee.

The database sources contacts through licensed data partnerships and public records, then refreshes each record on a 30 to 90 day cycle.

Access runs on pay-as-you-go credits with no subscription required, and exported lists sync into 1,000+ CRM platforms, including HubSpot, Salesforce, and Zoho, as CSV or Excel files.

BeSpoke is BookYourData's private, human-researched list-building service, built to a buyer's exact specification instead of pulled from the prebuilt database.

A research team assembles each BeSpoke list beyond the standard pool under the same 97% deliverability guarantee, useful for niche verticals, uncommon job titles, or account lists that a filter-based search alone leaves incomplete.
