Apollo.io

Apollo.io is a sales intelligence and outreach platform built around a 210M+ contact database, letting freelancers, agency owners and consultants find and email decision-makers directly instead of waiting for inbound leads. For anyone selling services online — freelance consulting, agency retainers, coaching, B2B SaaS — Apollo replaces cobbled-together lead lists with searchable, verified contact data plus built-in sequencing to run outbound campaigns. The Free plan is genuinely usable: full database access, 5 mobile credits and 10 export credits/month, unlimited email credits under fair use (~250/day), and up to 2 active sequences, enough for a solo freelancer to run real outreach at $0. Paid tiers are Basic (~$49/user/mo annual), Professional (~$79/user/mo annual) and Organization (~$119/user/mo annual), all priced per seat and cheaper billed yearly. The catch is the credit system: phone/mobile credits cost far more than email credits, they expire each cycle, and CRM integrations require a paid tier — a real 5-person team on Professional often runs $1,500-2,500/mo once credits and add-ons are counted. The standard comparison is Apollo vs Hunter.io: Apollo bundles a full contact database and sequencing, Hunter focuses narrowly on email finding/verification at a lower price. Best for freelancers, agencies and consultants who need to actively prospect for paying clients rather than rely on referrals.
