Pros & Cons
Kustomer
Pros
- The CRM timeline shows orders and history for each customer in one view, which gives both AI agents and reps full context.
- Channel coverage is broad and includes voice, WhatsApp and TikTok Shop alongside email and chat.
- The developer platform is extensive, with 10 REST APIs, webhooks, mobile chat SDKs and an MCP server.
- Its compliance coverage is strong: SOC 2, ISO 27001, ISO 27701, ISO/IEC 42001 and GDPR.
- G2 reviewers rate it 4.5 out of 5 across more than 500 reviews.
Cons
- No prices are published, so every buyer must go through a sales quote.
- G2 reviewers report pricing model changes announced with short notice.
- Reviews describe a steep learning curve and setup that often needs dedicated admin staff.
- Some end users on Trustpilot criticise the customer-facing AI for rigid flows and difficulty reaching a human.
- AI features are billed on top of the platform, which raises total cost.
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.
