2025 marked a pivotal shift for customer-facing conversational AI (CAI).
Last October, I published an industry landscape featuring 650 players and highlighted how difficult it was to break through. For years, the market was defined by the three hyperscalers, AWS, Google, and Microsoft, alongside a small cohort of challengers struggling to break through the $100M ceiling and a long tail of sub-$20M players. CRM and CCaaS providers either built solutions using hyperscaler building blocks or partnered with specialists, yet made limited inroads.
In 2025, the lay of the land was redrawn.
A handful of pure-play providers have now crossed the $100M threshold. Kore.ai was the first, based on my research, to break that ceiling, followed by three others:
Uniphore, which indicated last October alongside its Series F that it was well past $200M, with scale accelerated by acquisitions.
SoundHound AI, benefiting from the acquisitions of Amelia and Interactions, ended last year at $170M in revenue.
Sierra reported reaching $150M in ARR last December.
2 players emerged from the customer support automation corner: Zendesk, which reached $100M in AI ARR last year, and Fin by Intercom, whose CEO Eoghan McCabe disclosed earlier this month that it was about to pass $100M ARR.
Closely behind, a solid cohort of followers above $50M is well-positioned to cross the $100M ARR mark soon, including Ada, Cresta, LivePerson, Observe.AI, Parloa, and Yellow.ai.
ElevenLabs, coming from the Voice AI space, entered the market. While it is difficult to isolate the CAI portion of its $330M ARR last year, it is likely material, and I would not be surprised to see it in this group.
CCaaS providers that relied on partners or hyperscalers are now building or acquiring their way into proprietary CAI offerings. They are likely the largest contributors to NICE AI and Self-Service ARR ($328M in 2025), Genesys Cloud AI ARR (estimated at around $300M in 2025), and Five9 AI ARR ($100M last year).
CRM players have also been aggressively putting together their own CAI offerings, positioning Oracle (Digital Assistant), Salesforce (Agentforce), SAP (CAI/Joule), and ServiceNow (Now Assist) as significant players. We should also include IBM (Watson Assistant) in this group.
Three engines are driving this growth.
First, the incredible pace of progress across three key technologies—GenAI, Agentic AI, and Voice AI.
Second, CAI is enabling new use cases that go beyond what was previously possible and are setting a new benchmark for customer experiences. Three are now mature solutions consistently delivering tangible results: customer support automation, concierge agents unifying sales and service into a continuous assisted experience, and autonomous agents qualifying and processing contact or demo requests, with others gaining traction in proactive service, nurturing and re-engagement, and back-office customer service fulfillment.
Third, businesses are ready to modernize their digital front door. Self-service has consistently topped the priority list for customer service organizations for over a year. A similar trend is emerging in sales to manage incoming appointment and demo requests.
Adoption is accelerating as technology redefines the art of the possible in customer experience. Large CAI players are beginning to establish themselves, coming from the various corners of this vibrant market.
