Apollo

B2B contact data plus AI agents for prospecting and outreach

Visit apollo.io

Apollo is a go-to-market platform that combines a large B2B contact database with AI agents for prospecting, outreach and dialing, plus a workspace to run that work in one place.

The product is built in three layers: data (Apollo's own records, your CRM and product data, and third-party signals), intelligence (agents that research accounts, prioritize leads, write outreach and book meetings), and execution (outreach from Apollo's Workspace or from tools your team already uses). Apollo says more than 600,000 companies use it, and it offers a free plan with no credit card required.

What Apollo does

B2B contact and account database

Apollo Data gives access to 240M+ contacts and 30M+ accounts, with the company stating 98% email accuracy. Records can be refreshed over time rather than staying static.

AI agents for prospecting and outreach

Agents run in the background to research accounts, build lists, write outreach, follow up and book meetings, prompting you at key moments. Agent memory is described as getting sharper over time.

AI Context Center

You train agents on your ideal customer profile and your product so their research and messaging follow your positioning rather than generic templates.

Waterfall enrichment

Multiple data sources are chained to fill in missing fields, aiming at more complete records before a rep or agent acts on them.

Apollo Anywhere and MCP integrations

Apollo connects to tools you already use, including Claude, ChatGPT and Gmail, plus a Chrome extension and an MCP integration. The site lists 200+ integrations overall.

Calling and deliverability tools

The feature set includes a parallel dialer for calling and deliverability tooling for outbound email, alongside sequencing inside the Apollo Workspace.

Apollo pricing

Freemium
  • Apollo uses a freemium model with four plans: Free, Basic, Professional and Custom.
  • Free is for exploring Apollo or very light usage and is aimed at founders and early-stage teams.
  • Basic covers individual sellers doing regular outbound and includes email sequencing and core integrations.
  • Professional is for full-time reps and adds higher credit limits, AI features, call recording and advanced CRM integrations.
  • Custom is for teams; the pricing page text reviewed does not list dollar amounts for any tier, so check the pricing page or request a demo for current rates and billing terms.

Pros

  • A free plan lets you test prospecting without a credit card.
  • One database and workspace cover lists, outreach, sequencing and dialing instead of separate tools.
  • Agents can work inside Claude, ChatGPT and Gmail, so reps do not have to switch to a new interface.
  • Waterfall enrichment and ongoing data refresh help keep records usable for both reps and agents.
  • A Chrome extension brings Apollo data into the browser where prospecting often starts.

Cons

  • AI features, call recording and higher credit limits are reserved for the Professional tier and above, not the Free or Basic plans.
  • The Free plan is described as intended for exploring or very light usage, so regular outbound needs a paid tier.
  • No dollar amounts for any plan were listed on the pricing page text reviewed, so costs require a demo or sign-up step.
  • Access to the underlying dataset is tied to plan tiers, with credit limits differing between Basic and Professional.
