Apollo.io

Apollo.io is an AI-powered B2B sales platform for sales teams, SDRs, revenue operations, and marketers who need to find, engage, and close leads at scale. It combines one of the largest business contact databases with outbound sequencing, inbound lead routing, data enrichment, and deal execution tools in a single platform. Pricing details are not listed publicly, but a free tier is available with no credit card required.

Sales teams typically stitch together separate tools for prospecting, enrichment, sequencing, and conversation intelligence — driving up costs and creating data gaps. Apollo.io consolidates all of these into one platform: reps can identify prospects from a continuously refreshed contact database, automate outbound sequences, instantly qualify and route inbound leads, and capture deal conversations, all without switching tools. Customers report a 70% increase in sales leads and 4x SDR efficiency.
