Apollo.io
You are not misreading Seamless.AI's pricing link: on 26 October 2026 it opened an inquiry form offering "special pricing", with no figures, while Apollo.io sells a Basic seat at $65 a month that you can cancel month to month, per the Seamless.AI pricing page and the Apollo pricing page.
Seamless.AI vs Apollo.io: A Sales Contract or a Monthly Seat
Clay
For a sales floor that researches contacts all day and calls most of them, Seamless.AI's model fits: one credit researches a contact with its emails and phone numbers, and a Pro license carries 10,000 credits a month, per its credit article, though the price only arrives after an inquiry form on its pricing page.
ZoomInfo
Both put a form where the price would be: Seamless.AI's pricing link opens an inquiry for "special pricing", and ZoomInfo's pricing page lists packages with no figures, per the Seamless.AI and ZoomInfo pricing pages checked on 26 October 2026.
