$49/mo Free tier Free trial MCP API
Why it comes up: Apollo publishes a $49/mo data-plus-sequencer plan with a free tier, while Rox meters AI agent actions from $100/mo.
Stands out: A large people database plus email sequences in one login, with MCP and a Chrome extension.
Watch out: Data quality varies by segment, and it does not match enterprise tools for intent data and org charts.
Best for
- Outbound recruiting and sales on one database
- Teams that want free-tier access to start
- Desks that need sequences next to the data

Why it comes up: Clay is a waterfall enrichment worksheet with Claygent on every row, not an always-on revenue agent swarm.
Stands out: 150+ provider waterfall plus Claygent on every row, with MCP and API.
Watch out: Not a sender. Paid plans start at about $167/mo, with Launch from $185/mo, and credit burn adds up.
Best for
- Sourcers building enriched spreadsheets
- Teams chaining many data vendors
- Desks that want Claygent research columns

Why it comes up: 11x sells named digital workers (Alice, Julian) on a high quote, while Rox publishes Individual at $100/mo.
Stands out: Alice Growth prints $3750/mo billed annually and includes domain setup, warmup, inbox rotation, monitoring, and bi-directional CRM sync for up to 5 end users.
Watch out: Annual is the default. Pro and Enterprise are custom. Julian (inbound voice/chat) is a separate SKU. There is no public trial.
Best for
- B2B teams replacing a first SDR pod with an outbound digital worker
- RevOps that want mailboxes, warmup, and CRM sync bundled instead of five vendors
- Companies that can commit annually and feed Alice 2,000 new prospects a month

Why it comes up: AiSDR is a signal-based AI SDR from a published $250 starting point, not a 10,000-action monthly pool.
Stands out: A public $250 Solo plan (200 AI-researched contacts) with HubSpot, Salesforce, Close, Clay and Calendly named, and cancel-anytime terms.
Watch out: Explore is $900/mo and Scale $2,500. There is no free trial; the vendor says warmup makes a 30-day window pointless. Per-campaign managed service is extra.
Best for
- Founder-led sales that want an AI SDR with a public price
- HubSpot or Salesforce shops
- Teams comparing Ava and Ami
