What our research says

Affinity

The strongest argument for Affinity is that dealmakers do not update CRMs, and this one does not ask them to — the pipeline is assembled from mail and calendar activity that already exists. Add the private-capital data sources and the MCP endpoint and it is a defensible category leader for firms whose asset is their network. The price is the whole objection: 2,000 dollars per seat per year before anything is customised, with annual commitment and no trial figure in sight.

Pros

  • Contacts, activity and relationship scores captured automatically from email and calendar
  • Warm-path surfacing across the whole firm's network, not just one user's contacts
  • Integrations with 40-plus data sources including Pitchbook and Preqin
  • Open API and an MCP endpoint that exposes the CRM to Claude, ChatGPT and Snowflake
  • Pricing is published rather than hidden behind a demo

Cons

  • Entry tier costs 2,000 dollars per user per year, billed annually
  • No free tier and no monthly billing option
  • Automatic capture means the firm's mailboxes and calendars are ingested, which is a governance conversation
  • Enrichment and the deeper integrations sit on the Advanced tier, not the entry one

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

Which one fits

Choose Affinity if you need

Choose Attio if you need
