Our verdict
Premium enterprise agentic platform — outcome-based in principle, but you'll need a procurement team to learn what it costs.
Strengths
- High-end agentic + voice
- Outcome-based (don't pay for failures)
Watch-outs
- No public per-outcome rate
- Year-1 implementation can match licensing
- Enterprise budgets only (estimates ~$150k+/yr)
Who it's for
Large enterprises wanting voice + complex agentic workflows. Typically a fit for enterprise teams.

Sierra alternatives
Pay-as-you-go free start ($5 AI credit); Team $495/mo
Powerful for builders, but treat the plan price as a floor — your real bill depends on AI Spend (tokens × model).
ChatbaseFree; Hobby $40/mo
Great for a quick, embeddable site bot — just remember model choice is the real cost lever, not the headline plan price.
Chatfuel$69/mo single plan
A tidy flat price for Meta-channel commerce — just budget the separate WhatsApp conversation fees Meta charges on top.
CrispFree (2 seats); Mini $45/mo (4 seats)
The cheapest flat entry for a small team — predictable until heavy automation burns through the included AI credits.
