8.6

Apollo compressed what used to be three subscriptions - a contact database, an email sequencer and a sales dialer - into one tool at a price that made the incumbents sweat. The database is the star: veriable emails and direct dials filtered by role, industry, tech stack and funding stage, deep enough that most SMB prospecting lists build themselves in an afternoon. Sequences and the dialer are competent rather than best-in-class, data accuracy dips outside the US, and the credit math on higher tiers needs reading twice. But dollar-for-dollar, nothing in outbound touches it - which is exactly why it is the default first stack for lean sales teams.
