Prospecting and lead data

About Apollo.io

Contact and company database joined to sequencing, a dialer and enrichment, so reps can find prospects and contact them in one tool.

Apollo.io combines a large B2B contact and company database with the tools to act on it. A rep can filter by title, company size, industry, location and technology used, save a list, and add those people to an email sequence without leaving the product.

It also enriches records already in your CRM, filling in missing emails, phone numbers and company details, and its browser extension shows contact data while you are on LinkedIn or a company website. AI features help write emails and suggest which accounts to work.

Small teams often use Apollo as their whole outbound stack, while larger teams use it for data and enrichment next to a separate engagement tool. Contact data is never perfect, so test a sample from your own target market, check bounce rates on found emails, and read how the data is sourced and how opt-out requests are handled in the regions you sell to.
