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.

Salesloft

Pros

• G2 reviewers score its interface well for ease of use (8.8) and ease of setup (8.5), ahead of Outreach on both.
• The Rhythm AI engine turns intent and engagement signals into a single prioritized daily task list for reps.
• Built-in call recording and conversation intelligence can remove the need for a separate tool such as Gong.
• Reviewers describe its Salesforce integration as deep and mature.
• Since the Clari merger, it can combine engagement with Clari Forecast and pipeline inspection in one platform.
• It holds SOC 2 Type 2, ISO 27001 and ISO 27701 certifications.

Cons

• Salesloft publishes no prices, and third-party estimates suggest high per-seat costs on annual contracts with 5 to 8 percent escalators.
• The dialer is click-to-call only with no power dialer, and it is often an extra-cost add-on.
• Users report duplicate records, broken reports and sync delays with the HubSpot integration.
• Reviewers describe slower support and reduced account management after the acquisitions.
• It is not a standalone CRM, so a separate Salesforce or HubSpot license is still required.
• The 2025 Drift OAuth breach and the sunset of Drift have raised concerns about vendor stability.
