    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.

    Verdict

    What we'd pick for an ANZ healthcare network

    Pick Sierra when
    • Voice is the primary patient channel and SMS/web are secondary.
    • Network wants a single agent across voice + outbound recall + SMS.
    Pick Decagon when
    • 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.
    Net-net

    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.
