Persana AI vs Warmly

Persana AI was a web-based go-to-market platform for prospecting and outreach, combining data, AI enrichment and CRM automation. Its site described more than 100 data providers covering contact, company, technology and funding information, alongside more than 75 buying-intent signals such as hiring, job changes, funding, website visits and keyword intent. AI research agents analyzed companies, generated personalization insights, tracked competitive information and scored leads. An integrated AI email sequencer offered scheduling and deliverability features, and listed integrations included HubSpot, Salesforce, Gmail, Instantly, Outreach, Smartlead and Lemlist. The platform also listed webhooks and an HTTP API; Growth included support for a bring-your-own API key. Its status is the key consideration: Persana says billing stopped on April 1, 2026, access ended May 1, and the platform shut down May 2. It said remaining platform data would be permanently deleted and advised customers to export data and move workflows to Rox as the team joins that company. Plans included a free option and paid plans, though the listed prices may no longer be actionable.

Warmly describes itself as an autonomous revenue agent platform for B2B go-to-market teams. Its Inbound Agent identifies website visitors at the person level and offers AI chat with Context Graph context, intent-based popups, and personalized microsites. The platform also lists company and people search, intent signals, phone numbers, and an email finder.

Warmly provides an MCP server with OAuth access and REST endpoints authenticated by API key; its three tools are read-only.

The free API/MCP plan is free and includes 250 credits per month; paid API/MCP plans start at $99 a month. Annual web-deanonymization starts at $10,000 a year, Inbound Chat at $20,000 a year, and AI Inbound Autopilot at $30,000 a year, each from 10K credits per month.
