AI features shipped
Apollo advertises an agentic GTM system: agents research accounts, build lists, write outreach, follow up and book meetings, trained via the AI Context Center and agent memory. It also runs inside Claude, ChatGPT, Gmail and the browser (Apollo Anywhere). No source states which model keys customers may supply or whether per-action AI logs can be exported.

Industry verdicts
How Apollo.io speaks to each vertical it serves — same data, sector lens.
Professional ServicesBill hours faster, staff smarter.
Best for in Professional Services
- Consultancies, agencies and B2B services firms running high-volume outbound prospecting
- Outsourced SDR and GTM teams that need contact data plus sequencing in one subscription
- Revenue teams prospecting by role and title across large enterprise accounts
Not for
- B2C businesses with no B2B prospecting motion
- Firms that want to embed or resell contact data inside a client-facing product
Apollo is a horizontal B2B go-to-market platform rather than a vertical product, and professional services is a core fit: named customers include Ernst & Young, Oracle and Lyft, and Apollo reports 600,000+ companies and 40,000 paying customers. The database, sequencing, dialer and AI agents suit consultancies, agencies and outsourced SDR teams that prospect by role and title. Plans are for internal business use only, so data-embedding business models need a separate agreement and custom pricing.

Founded in 2015, Apollo reports 600,000+ companies and 40,000 paying customers, a free-forever Starter plan, and enterprise governance and admin controls.
Frequently asked questions
What does Apollo.io cost and how is it priced?
Apollo uses a freemium model: a free-forever Starter plan, paid plans billed monthly or annually that scale by plan and seat count, and Custom plans for large enterprises. Usage runs on credits, with unlimited plans under a fair-use cap (for example 10,000 credits per account per month for non-paying accounts). Extra credits can be bought at any time, and export or mobile credits are consumed when data leaves Apollo or dialing is used. Current list prices for paid tiers were not published on the pages reviewed, so confirm seat pricing with the vendor.
How quickly can a team get value from Apollo?
Quickly. Signup is free with no credit card, and trial plans include 50 credits, 5 mobile credits and nearly all features of the selected plan. Because onboarding is self-serve and 200+ integrations cover CRM, email and calendar tools, most teams run initial searches and sequences within days rather than months. Enterprises should still budget time for security review, integrations and governance setup before a full rollout.
Which systems does Apollo integrate with?
Apollo lists integrations with Salesforce, HubSpot, Outreach, SalesLoft, Marketo, Sendgrid, LinkedIn and all major email providers, and advertises 200+ integrations overall. Teams can work inside Apollo's workspace or from CRM, Gmail, ChatGPT, Claude and the browser via Apollo Anywhere. API access is offered on Custom plans for more advanced integrations.
Can we use Apollo data to power our own product or share it with customers?
No. The plans published on Apollo's pricing page are licensed for internal business use only; powering external products, sharing data with customers, or reselling Apollo data requires a separate agreement with custom pricing and terms. Buyers with data-embedding use cases should scope that contract early rather than assuming a standard seat plan covers it.
What compliance and security evidence does Apollo provide?
Apollo states it is GDPR compliant and lists SOC 2 Type II, ISO/IEC 27001, CCPA, CPRA, PCI DSS, EU-US DPF and CASA Tier 2 credentials among its enterprise security materials, alongside governance, admin controls and permissions for multi-team organizations. Buyers should request the current trust report, data-processing terms and opt-out handling during procurement, since certifications could not be verified against a dedicated trust page in this review.
How are Apollo's AI agents governed?
Apollo describes agents trained on your ICP and product through the AI Context Center, with memory that sharpens over time, prompted at key moments and able to prospect from goal to booked meeting. Apollo says agents are designed to help keep prospecting compliant, with built-in support for consent and opt-out rules such as GDPR, CAN-SPAM and DNC, and enterprise plans add governance, admin controls and permissions. The vendor does not state which model keys customers may supply or whether per-action AI activity can be logged or exported.
