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.
Aviso
Pros
- Forecasting accuracy is strongly backed: customer stories cite LaunchDarkly at more than 98 percent and New Relic at more than 99 percent.
- Combines forecasting, conversation intelligence, sales engagement and agentic AI in one platform, which can replace several separate tools.
- Can take in data from data warehouses as well as the CRM, which suits consumption-based revenue models.
- Rated well across a large review base, around 4.3 to 4.4 out of 5 on G2 from more than 950 reviews.
- The pricing proposal includes free migration and an offer to buy out an existing vendor contract.
Cons
- No public pricing, and Vendr-reported contracts run roughly 25,000 to 85,000 USD a year.
- G2 reviewers frequently report slow loading and freezes.
- Salesforce sync problems, including missing opportunities, come up repeatedly in reviews.
- Implementation typically takes 6 to 12 weeks and has a learning curve; one Reddit user found its training resources thinner than Clari's.
- It is not a standalone CRM, so it needs an underlying system such as Salesforce.
