The honest brief

Decagon

Prices per conversation or resolution, not per seat, and lets ops teach agents via natural-language procedures.

  • Outcome-based pricing
  • Ops author logic, engineers keep guardrails
  • Chat, email, and voice
  • Takes actions, not just answers
  • Enterprise sales-only
  • Setup and tuning required
  • Model choice abstracted away

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
