Five9 vs ConnexAI:
Which is right for you?
Two platforms, two trade-offs. Here’s how they actually compare.
Summary
Five9 is battle-tested for large US operations but demands 50+ seats and $300–$600 real TCO once you add AI, WFM, QA, and CRM connectors. ConnexAI undercuts Five9 significantly at ~£85–95/user/month with Athena AI included and UK hosting, but users report bugs and platform instability that undermine the savings. The choice comes down to paying more for reliability or paying less and accepting risk.

Common questions:
What is the main difference between Five9 and ConnexAI?
Five9 is a mature US platform with deep integrations but high costs ($300–$600 real TCO) and a 50-seat minimum. ConnexAI is a UK-based AI-first challenger at ~£85–95/user/month with Athena AI included, but users report platform bugs and stability issues. Five9 trades cost for reliability; ConnexAI trades stability for savings.
Is there a better alternative to both Five9 and ConnexAI?
QContact delivers UK hosting and included AI like ConnexAI, with the reliability of Five9 — at £57/user/month. SOC2 Type II certified, 100% uptime record, and no seat minimums.
Does Five9 offer UK data hosting?
No. Five9 is US-based with no UK data centre option. If UK data sovereignty is a requirement, particularly for financial services, healthcare, or public sector, Five9 won’t meet it. ConnexAI and QContact both offer UK-hosted infrastructure, with QContact running on UK Azure.
How much does Five9 actually cost compared to ConnexAI?
Five9 starts at $119/user/month but real-world costs reach $300-$600/user/month once you add AI, workforce management, quality assurance, and CRM connectors. ConnexAI is simpler at around £85-£95/user/month with AI included, but fewer enterprise features. QContact includes everything — AI, CRM, workforce management, quality assurance, at £57/user/month with no add-ons.
Can I use Five9 or ConnexAI with a small team?
Five9 requires a minimum of 50 seats, so it’s not an option for smaller operations. ConnexAI has no published minimum but pricing is less transparent at lower volumes. QContact starts from 10 seat with the same features and pricing regardless of team size.
