Perplexity Enterprise

Pros

• Answers come with citations to sources, which makes verification easier for research-heavy teams.
• Users can switch between multiple frontier models from OpenAI, Anthropic and Google within one seat.
• Strong security baseline for the price, with SOC 2 Type II, SSO, SCIM, HIPAA support and no training on enterprise data.
• Pro and Max include premium finance and market data sources such as PitchBook, Statista and S&P Capital IQ.
• The entry seat price of about $40 per month is low compared with many enterprise AI suites.

Cons

• Audit logging and data retention controls reportedly need at least 50 seats or an Enterprise Max user.
• Usage caps have changed with little notice, and users have complained about reduced Pro limits in 2026.
• It is an answer engine and cannot take actions such as updating tickets or CRM records.
• API usage is billed separately on top of seat fees.
• Users report slow support responses, and independent sources disagree on the published limits and Enterprise Max pricing.

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.
