Pros & Cons
Attio
Pros
- The custom objects and attributes let teams model non-standard processes such as fundraising or partnerships.
- Email and calendar sync builds and enriches contact and company records automatically.
- A Free plan for up to 3 seats and transparent per-seat pricing make it easy to start.
- Pro call intelligence records Zoom, Meet and Teams calls and fills fields from transcripts.
- Developers get API access on every plan, plus webhooks, an App SDK and an MCP server.
Cons
- The native integration catalog is smaller than HubSpot's or Salesforce's.
- Mailbox sending caps make it unsuitable for high-volume outbound SDR teams.
- Plus stops at 10 seats, so the 11th seat forces an upgrade to Pro.
- AI features and workflows draw on credit pools that can run out.
- Reviews say the mobile app has fewer features than the web version, and some report inconsistent support.
Twenty
Pros
- Teams can create custom objects, fields and views without code, which makes the CRM flexible to model.
- The open-source core can be self-hosted at no licence cost, which avoids vendor lock-in.
- REST and GraphQL APIs, webhooks and an MCP server are included on every plan.
- At 9 USD per user per month, the Pro cloud plan costs far less than Salesforce or HubSpot.
- Google and Microsoft email and calendar sync is built in.
Cons
- There is no native mobile app, and users say the responsive web interface is hard to use on a phone.
- Reporting and forecasting are basic compared with Salesforce, according to reviewers.
- The integration ecosystem is small, so some connections need custom API work or Zapier.
- Self-hosting puts updates, security patches and backups on your own team, and the AGPL licence carries obligations if you modify the code.
- SSO, audit logs and fine-grained roles require the 39 USD Organization plan.
