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.
Membrain
Pros
- Teams can model their own sales process, qualifiers and milestones in it, which reviewers on Spotsaas and G2 single out.
- Built-in coaching and guidance, including the Elevate coaching product, OMG assessments and in-app advice, support sales methodologies such as Baseline Selling.
- Reviewers repeatedly praise fast, knowledgeable support, and one customer has stayed more than 10 years.
- Broad integration list covering Gmail, Outlook, HubSpot, Salesforce, Business Central, Fortnox, Zendesk, Slack, plus Zapier and webhooks.
- Pricing is public and modular, so teams pay only for the stages (prospecting, pipeline, account growth) they use.
Cons
- Reviewers often say reporting and dashboards are hard to customise and give limited statistics.
- Setting up custom processes and dashboards takes significant upfront time.
- Reviewers report that Outlook email integration is limited and that companies can be duplicated during data entry.
- API+ (499 USD) and Automation+ (299 USD) are costly account-wide add-ons on top of per-user fees.
- The vendor is small, with about 11 to 50 employees, and its compliance is reported as SOC 2 Type 1 only by a third-party listing.
