Sierra vs Decagon
Both are agentic CX platforms aimed at enterprises, not voice infra. For ANZ healthcare networks above 30 sites, they enter the shortlist alongside the voice-first set.
Sierra and Decagon are the same shape of company: founder-led agentic CX platforms with enterprise security postures and managed-service overlays. Voice is one channel, not the product.
For ANZ healthcare networks running cross-channel (voice + SMS + web), the question becomes whether the per-clinic price holds up versus a voice-first stack plus a separate inbox.

What we'd pick for an ANZ healthcare network
- — Voice is the primary patient channel and SMS/web are secondary.
- — Network wants a single agent across voice + outbound recall + SMS.
- — Patient support volume is heavily inbound text/web, with voice as overflow.
- — Existing enterprise stack already has a strong voice tier (e.g. NICE) you want to keep.
For a 50+ site ANZ healthcare network where voice is the dominant channel, Sierra has the edge. Decagon catches up when text channels dominate.
FAQ
Cheaper than building on Bland/Retell/Vapi + a partner?
No. Sierra/Decagon are typically 2–4× the all-in cost. They earn it by removing partner-build risk for networks that don't want to own an integration team.
Will either deploy in 6 weeks?
No. Plan for 8–12 weeks minimum to first pilot. Voice-first infra plus a partner is faster if speed is the constraint.
