What our research says

Attio

Attio is the CRM to look at when your sales motion does not fit HubSpot's shape — the object model bends, and the AI features read from that model rather than being bolted on. Call Intelligence and unlimited seats only arrive at the Pro tier, which is where the price starts to bite. The MCP server is the genuinely differentiating piece if your team already works through Claude or ChatGPT.

Pros

  • Free tier covers three seats with contact syncing and enrichment
  • Call Intelligence records, transcribes and logs calls natively on Pro
  • Workflows can be described in natural language instead of hand-built
  • Official MCP integration exposes CRM data to Claude and ChatGPT

Cons

  • Call Intelligence, sequences and permission controls are Pro-only
  • Plus caps at 10 seats, forcing a jump to Pro as the team grows
  • Per-seat pricing at the Pro tier is expensive for wide rollouts
  • Enterprise is annual-billed and custom-quoted

Twenty

The most active open-source CRM on GitHub by a wide margin, and the rare one that does not feel like a 2010 admin panel. You get schema control and a real migration path off Salesforce, but the cloud tiers are young and the enterprise floor is steep once you need SSO-grade support.

Pros

  • Full source on GitHub with commits landing daily
  • Custom objects, fields and views without a paid tier gate
  • Native MCP server plus an API, so agents and scripts work against the same data
  • Migration tooling built for tens of thousands of records
  • Self-hosting is genuinely free, not a crippled community edition

Cons

  • Enterprise pricing jumps to $50k a year with nothing in between $19 a seat and that
  • Ecosystem of integrations is thin next to HubSpot or Salesforce
  • Self-hosting means you own upgrades, backups and uptime
