Sierra

Pros

• Outcome-based billing means customers usually pay only for resolved conversations or other agreed results, not for each seat.
• Three build options cover both CX teams and engineers: the no-code Agent Studio, the code-first Agent SDK, and Ghostwriter for building agents from SOPs.
• One agent runs across chat, voice, SMS, WhatsApp, email and ChatGPT, keeping context between channels.
• Its list of compliance attestations is broad, covering SOC 2, ISO 27001, ISO 42001, HIPAA, PCI DSS and FedRAMP.
• It has a strong roster of enterprise customers, including SiriusXM, ADT, Rocket Mortgage and SoFi.

Cons

• There is no public pricing, and competitor estimates put annual contracts at about $150,000 or more.
• There is no self-serve or trial tier, so small teams cannot try it on their own.
• Implementation is largely vendor-led, which can make customers depend on Sierra's team for changes.
• There are few public reviews (7 on Gartner Peer Insights) to verify claims against.
• Some reviewers say voice quality still falls short of human level, and that complex telephony setups depend on how far the integration goes.

Workativ

Pros

• Session-based pricing with unlimited end users avoids the per-employee fees common in this category.
• Agents carry out real actions, such as Okta, Azure AD and Active Directory password resets and ServiceNow or Jira tickets, rather than only answering questions.
• Works inside Slack and Microsoft Teams, where employees already ask for help.
• The security page lists ISO 27001, ISO 27701, GDPR and HIPAA compliance, plus SOC 2 audits.

Cons

• When a plan's sessions run out, the agent stops responding for the rest of the billing period, and no overage option is published.
• The Business plan is capped at 2 agents and 5 actions, which pushes larger teams toward custom Enterprise pricing.
• There are few independent reviews: only a handful each on G2 and Capterra.
• There is no free trial or self-serve signup, so buyers must book a demo.
• A competitor's review reports that SSO, MFA and role-based access are Enterprise-only and that no public API was found.
