Pros & Cons
Sana
Pros
- Sana claims more than one million users, including Merck and Polestar, and the product is now backed by Workday.
- Integrated sources keep their original permissions, which reduces the risk of oversharing in knowledge search.
- Includes SAML SSO, SCIM, AES-256 encryption at rest and a single-tenant deployment option.
- Handles many content types, including meeting recordings, Office files, spreadsheets and video.
- Non-technical staff can build agents with the no-code builder and extend integrations through an MCP client.
Cons
- There is no public pricing. Only a custom Enterprise quote is available.
- The Free and Team plans were removed in 2026, so there is no way for small teams to start.
- Independent reviews are scarce: Gartner Peer Insights showed only one rating.
- Vendor pages contradict each other on SOC 2 status, listing both Type 1 and Type 2.
- The roadmap now depends on Workday's agent strategy, which may matter less to companies that do not use Workday.
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.
