๐ŸŽง Knowledge base quality is the real AI support product

PM AI Customer Support
(2026 Edition)

Sixty percent-plus deflection is now the benchmark enterprise buyers expect from AI support tools such as Decagon, Ada, and Fin โ€” a bar only reachable when the underlying knowledge base is genuinely good, since a bot is only as useful as what it can retrieve. PMs in this category watch deflection rate, CSAT on AI-handled tickets, and how cleanly unresolved queries hand off to a human.

FAQ

Is AI customer support a real category in 2026?

Yes, and scaling fast. Decagon, Ada, Fin (Intercom), and Sierra have material ARR. Enterprise buyers now expect 40โ€“60% deflection, not 'can we try a chatbot?'. The shift from rule-based bots to LLM-powered agents is largely complete in 2026.
