Apollo.io

Apollo.io is an all-in-one B2B sales intelligence and engagement platform combining a 275M+ contact database with autonomous outreach automation, email sequencing, a built-in dialer, and CRM sync. Founded in 2015, $251M raised, valued at $1.6B. Used by 600,000+ companies from early-stage startups to Fortune 500 enterprises including Ernst and Young, Oracle, and Lyft confirmed on the vendor website. The core agentic capability is autonomous sequence execution. Once a prospect is enrolled in a sequence, Apollo sends emails, waits for replies, follows up based on engagement behavior, and logs all activity to your CRM without requiring human approval at each step. AI-powered Plays are multi-step automated workflows triggered by prospect signals including job changes, funding rounds, hiring activity, website visits, and intent data events. When a trigger fires, Apollo enriches the contact, enrolls them in the configured sequence, and begins outreach automatically. This is genuine outbound automation running continuously in the background, not a manual prospecting database that requires human intervention per record. AI Research generates personalized insights per prospect automatically before outreach begins. AI Lead Scoring prioritizes prospects based on fit signals without manual scoring rules. The AI Assistant is included as introductory free on all paid plans, providing conversational access to Apollo data and workflows. AI Writing is available across all tiers with word limits scaling from 5,000 words per month on Free to 1,000,000 on Organization. Projects (BETA) enable structured campaign organization, available on all plans with unlimited projects on Professional and above. Recommendations (BETA) surface AI-powered next-step suggestions. Integration depth is action-level, not read-only. Apollo writes to Salesforce and HubSpot natively, creating contacts, updating field values, logging email and call activity, and syncing sequence enrollment status bidirectionally rather than just reading records. Outreach and Salesloft connect as sequence platforms for teams that run Apollo for data and a separate SEP for execution. The Salesforce extension and Gmail extension enable Apollo workflows directly within those interfaces. Additional integrations include Marketo, SendGrid, and LinkedIn. API access (Professional tier and above at $79/user/month) enables programmatic enrichment, contact export, and custom workflow automation. Apollo MCP (listed as a standalone product in the platform navigation) connects Claude and other AI assistants directly to Apollo data and workflows for natural language prospecting, list building, and campaign analysis. Pricing uses a per-seat subscription plus credit-based consumption model. Free tier: $0, 900 credits per seat per year granted monthly, AI Assistant (5 chat limit), AI Research, 2 sequences, 2 workflows per team, 250 daily email sends, basic filters, Gmail and Salesforce extensions. Basic: $49/seat/month (annual), 30,000 credits per seat per year granted upfront, AI Assistant (introductory free), AI Research and AI Lead Scoring, unlimited sequences, 5 workflows per team, 250 daily email sends, advanced filters, CRM integrations, waterfall enrichment, 6 intent topics. Professional: $79/seat/month (annual), 48,000 credits per seat per year. This is the minimum tier for API access. Includes automated workflows (50 per team), call recordings with AI insights (4,000 minutes), dialer, unlimited daily email sends, unlimited Gmail and Microsoft mailboxes plus 5 SMTP mailboxes per user, A/Z testing, and analytics with pre-built reports. Organization: $119/seat/month (annual), minimum 3 seats, 72,000 credits per seat per year. Includes advanced security, SSO, customizable reports and dashboards, 8,000 minutes of call recordings, 500 workflows per team, 15 SMTP mailboxes per user, and the ability to supply your own LLM API key. Monthly billing adds approximately 20%. Add-on products are available separately. The Inbound package costs $119/team/month and includes website visitor identification for up to 50,000 companies per month, domain tracking for up to 100 domains, and form enrichment for 5,000 contacts per month. The Advanced Dialer costs $119/team/month and includes parallel dialer, power dialer, international calling, and local presence. Total cost of ownership regularly runs 2 to 3x the advertised per-seat rate for active prospecting teams. Each email access costs 1 credit, each phone number 8 credits, and data enrichment 1 to 8 credits per record. AI Research costs 1 credit per run. US Dialer costs 2 credits per minute. Teams enriching 500+ contacts per month per rep will consistently exceed Basic plan limits. API access at Professional tier combined with programmatic enrichment volume is the most common source of budget overrun. Upgrades take effect immediately; downgrades take effect immediately but no refunds are processed mid-term. Cancellations take effect at the end of the billing cycle. Apollo is not the right fit for teams that need multichannel outreach beyond email and calling. lemlist at $87/user/month (Multichannel annual) adds LinkedIn automation, SMS, and WhatsApp in a single sequence builder that Apollo does not offer natively. Outreach and Salesloft serve enterprise sales teams needing conversation intelligence, deal execution workflows, and deep Salesforce governance that exceeds what Apollo provides at the Professional tier. For teams that need only a prospecting database without sequencing, ZoomInfo and Clay offer data-only access at different price structures and data source depth. Current state Q3 2026: Apollo holds SOC 2 Type II, ISO 27001, GDPR, and CCPA certifications confirmed from the Apollo Trust Center at trust.apollo.io. Apollo MCP is live as a standalone product page in the platform navigation. BETA features include Projects for structured campaign organization, Recommendations for AI-powered next-step suggestions, and People and Company Lookalikes for audience expansion. G2 reviewers rate Apollo.io 4.7 out of 5 across 9,673 reviews in the Sales Intelligence category.
