Sierra
Bret Taylor's enterprise CX agent platform - outcome pricing, big logos, no self-serve.
What is Sierra?
Sierra is an AI agent platform for customer service founded by Bret Taylor (former Salesforce co-CEO) and Clay Bavor. It builds production-grade agents across chat, SMS, WhatsApp, email, voice, and ChatGPT, with tooling like Ghostwriter that drafts agents from SOPs or transcripts. Customer roster - Rocket Mortgage, SoFi, Wayfair, SiriusXM, Discord - signals it's enterprise-only and the pricing model is outcome-based rather than seat-based.
Customer support chatbots, AI agents, and helpdesk automation tools for website and product support.

Business fit
Right for you if you're an enterprise brand with millions of customer interactions and want to pay per resolution rather than per seat. Skip if you're under 100 employees - there is no self-serve and no public pricing, and you won't get a sales call. The outcome-based model rewards real deflection but means you need clean baseline metrics before signing. Best fit is consumer brands and regulated enterprises with mature support operations.
How to evaluate Sierra
Use this category when support volume is growing faster than the team can handle manually.
Confirm the exact workflow
Map Sierra to one concrete workflow first, such as replacing enterprise ivr and chat with voice + chat ai agents. Avoid buying before the owner, trigger, output, and success metric are clear.
Check category fit
Check knowledge-base ingestion, answer citations, and handoff controls.
Compare practical alternatives
Shortlist Sierra against Chatbase, Intercom Fin, Tidio so the decision is based on fit, effort, and workflow ownership rather than brand recognition alone.
