What is Apollo?

Apollo is an AI GTM system that unifies data, intelligence, and execution into one connected GTM system, built so GTM teams can find, research, engage, and convert prospects without switching between tools. The platform spans a 240M+ person database with 98% email accuracy, multi-channel sequencing, a built-in power and parallel dialer, AI research and personalization, inbound routing, and revenue analytics, all in one workspace.

Apollo meets sellers inside the tools they already use. Apollo MCP, Apollo's Model Context Protocol, lets AI assistants like ChatGPT, Codex, Claude, and Perplexity surface Apollo data and actions directly inside those environments. The Chrome extension surfaces contact data across the web without leaving the browser. For technical and advanced users, Apollo CLI enables terminal-native access for headless GTM workflows and automation pipelines.

Apollo's market momentum backs that positioning. According to Ramp's vendor data, Apollo holds a 38% adoption rate among businesses purchasing in the Sales Data Providers category as of July 2026, up 5 percentage points year-over-year, and 34% of first-time category buyers chose Apollo over all alternatives. Apollo is also recognized as the 2026 MarTech Breakthrough Award Winner for "Best AI-Powered Sales Solution" and holds a 4.7/5 rating on G2.

Apollo offers transparent pricing starting at $49/user/month (annual billing), with a free tier available. Full pricing details are in the Pricing Comparison section below.

What is ContactOut?

ContactOut is a lead intelligence platform focused on providing verified email addresses and phone numbers for professionals. According to ContactOut, its database covers 350 million professionals across 40 million companies, with API access to 200 million emails and 100 million phone numbers. The platform is designed primarily for recruiters, sales representatives, and executive search professionals who need to locate and initiate contact with prospects.

ContactOut's core offering includes a Chrome extension for finding contact data while browsing, a search portal with filters across 20+ data points including job title, company, revenue, and skills, and email campaign automation for multi-stage outreach. The platform also includes an AI Personalizer for generating personalized email copy.

ContactOut states that its data is triple-verified with 99% confidence levels, and the platform is SOC 2 certified.

The Team and API tier expands access to what ContactOut claims is 700 million+ bulk profiles, adds Salesforce and ATS integrations, team management features, and a dedicated account manager. Individual tiers (Free, Email, Email + Phone) are limited to one user per company, which means teams need the Team/API plan for multi-seat access.

ContactOut serves teams that primarily need a reliable source of contact data and a lightweight email outreach layer. It does not include a native dialer, CRM-native sequencing, or the kind of workflow automation that full GTM platforms provide.

Feature Comparison

The table illustrates the core distinction: Apollo covers the full prospecting-to-engagement workflow including dialing, AI research, and multi-channel sequences, while ContactOut is primarily a contact data and email outreach tool. For teams that need to act on data immediately within the same platform, that gap is material.

Pricing Comparison

Apollo's full pricing breakdownon annual billing:

• Free: $0, 900 credits/year, 2 sequences, basic filters
• Basic: $49/user/month, 30,000 credits/year, unlimited sequences, CRM integrations, 6 intent topics
• Professional: $79/user/month, 48,000 credits/year, US dialer, 5 mailboxes, automated workflows, AI research
• Organization: $119/user/month (min 3 users), 72,000 credits/year, international dialer, 15 mailboxes, SSO, advanced security

ContactOut's pricing on annual billing:

• Free: $0, 5 emails/day, 5 phones/day, 5 exports/day (1 user per company; limited time)
• Email: $49/month (annual) or $99/month (monthly), unlimited emails, 300 exports/month, 1 user per company
• Email + Phone: $99/month (annual) or $199/month (monthly), unlimited emails, unlimited phones, 600 exports/month, data enrichment, 1 user per company
• Team / API: Contact sales, team management, API access, Salesforce and ATS integrations, 700M+ bulk profiles

A few structural points worth noting: ContactOut's individual plans are limited to one user per company, so any team needing multi-seat access needs to contact sales for Team/API pricing. Apollo's credit model applies across data enrichment and export actions, with credits scaling by tier.

Both platforms use a credit system for data actions, so reviewing export limits against your monthly prospecting volume is important before committing to either.

How Apollo Differs from ContactOut

The clearest difference is platform depth. Apollo is built to take a rep from ICP definition through booked meeting, with buyer intent signals, AI-researched outreach, multi-channel sequencing, a parallel dialer, and analytics all connected.

ContactOut is built around contact data access and email outreach. Teams that need to dial prospects, run coordinated multi-channel sequences, or route inbound leads need to look beyond what ContactOut's individual plans offer.

On the AI front, Apollo's capabilities extend well beyond email personalization. The AI Research Agent surfaces account-level context before outreach.

The AI Sequence Builder generates full sequences from a natural language prompt. AI call summaries are pushed directly to CRM after every call.

ContactOut's AI Personalizer generates personalized email copy, which is useful but narrower in scope.

Market momentum data reinforces Apollo's trajectory. According to Ramp's Sales Data Providers category data as of July 2026, Apollo is the fastest-growing vendor in the category, averaging +0.75 percentage points of adoption per month, ahead of all other tracked vendors including category-wide peers. That growth reflects teams actively choosing Apollo as their sales intelligence and engagement foundation.

Customer outcomes reflect the platform consolidation benefit Apollo delivers:

"We reduced the complexity of three tools into one." Collin Stewart, CEO at Predictable Revenue

"Apollo enriches everything we have: contacts, leads, accounts...And we don't really have to touch it, it just works." Mark Turner, VP of Revenue Operations at Built In

For teams evaluating the value of sales automation, Apollo's connected data, engagement, and analytics model means fewer handoffs between tools and a cleaner data trail from first touch to closed deal.
