Decision
Which one should you pick?
Choose Decagon if…
- High-volume enterprise support teams. The intended customer. The analytics only pay for themselves at volumes where a percentage point of resolution rate is real money.
- Support leaders who want to own agent behaviour. Operating procedures are editable without engineering, which is genuinely rare in this category.
- Fintech and e-commerce. Strong action integration for order, payment and subscription queries.
Skip it if: Enterprise-only, with no way to self-evaluate is a dealbreaker for you.
Choose Retell AI if…
- Businesses with real phone operations. The best fit — clinics, dealerships, home services, anyone with a queue and missed calls.
- Outbound calling teams. Batch calling, voicemail detection and retry logic are purpose-built for this and rare elsewhere.
- Teams needing human escalation. Warm transfer with context is handled properly rather than as an afterthought.
Skip it if: Voice quality behind the leader is a dealbreaker for you.
