11x vs Apollo
Both get framed as "AI sales," but they do different jobs. 11x sells fully autonomous digital workers that run your outbound; Apollo is a self-serve platform your reps use to prospect and engage.
11x
11x offers AI "digital workers" — Alice (an autonomous outbound SDR) and Julian (an inbound AI phone agent) — that prospect, personalize, and book meetings across email, LinkedIn, phone, and messaging. It has an enterprise posture (SOC-2 Type 2, well funded) and strong AI personalization. Pricing is sales-only (demo required), premium, and typically annual-contract with setup fees — not accessible for small teams or trials.
Best for: mid-market and enterprise teams that want to offload SDR labor and can commit to a contract.
Apollo
Apollo is an all-in-one go-to-market platform: a large B2B contact database (240M+ contacts) plus prospecting, enrichment, email sequencing, a dialer, and AI assists. It has a genuinely usable free plan and low per-seat entry (Basic around $49/seat/mo), with integrations to Salesforce, HubSpot, Outreach, and more. Costs scale with seats and credits, and data accuracy (direct dials) can be inconsistent.
Best for: SMBs, startups, and individual sellers who want affordable self-serve prospecting and outreach.
Which should you choose?
Pick Apollo if you want control, a free/low-cost entry, and to equip a team. Pick 11x if you are mid-market/enterprise and want to offload the outbound motion entirely and can commit to the price.
11x pricing is sales-only; verify both vendors' current terms before committing.
