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.
Revenue.io
Pros
- Calls and activities log natively in Salesforce, with recordings attached to the right records, which cuts manual data entry.
- Moments coaching prompts reps during live calls, and managers can listen in or whisper.
- Reviewers often praise support responsiveness and onboarding, and third parties report implementations of about a month.
- Strong review scores, including 4.7 out of 5 on G2 from more than 570 reviews and 4.9 on AppExchange.
Cons
- It only works with Salesforce, so HubSpot, Pipedrive and Zoho users cannot use it.
- Dropped calls, audio problems and freezing are the most common complaints, and one source says they are worst on mobile.
- No pricing is published, and Vendr data shows a median contract of roughly $59,000 to $64,000 a year.
- Users report a learning curve of 2 to 4 weeks and a complex admin setup.
- It includes no prospecting or contact data, so leads must come from another source.
