The honest brief

DevRev

Unifies customer support and product development on one knowledge graph, so resolved issues flow straight to engineering — most rivals automate support alone.

One system for support and engineering
Free Mini tier to start
Built on a knowledge graph
AI agents for tickets and search
Built-in analytics and agent studio

Pro and Max are quote-only
Consumption-credit pricing can be opaque
Broad scope means a learning curve

Sierra

Outcome-based pricing — you pay per successful resolution, not per seat or per conversation.

Pay per resolved outcome, not flat seats
Omnichannel: chat, voice, email, SMS, WhatsApp
Founder pedigree (Bret Taylor, Clay Bavor)
Heavy Fortune 500 adoption

Enterprise-only; contracts start six figures
Plus setup fees in the tens of thousands
Outcome definitions are negotiated and can drift
No self-serve or transparent pricing
