Five9 has landed a major Fortune 100 financial services CCaaS deal worth approximately $100 million in total contract value.
The five-year agreement will see Five9 serve as a core customer experience platform within the organization’s broader cloud migration.
It is expected to ramp to approximately $25 million in annual recurring subscription revenue once fully deployed.
More importantly, the deal was transacted through Google Cloud Marketplace, providing an early test of whether Five9’s Google partnership can help it win bigger enterprise contact center migrations.
Five9 first confirmed global availability through the Google Cloud Marketplace in February 2025, pitching the route as a way to simplify procurement, billing, and AI-driven CX deployments. This latest agreement suggests that strategy is starting to translate into larger enterprise CCaaS opportunities.
In discussing the news on the company’s Q2 2026 earnings call, Five9 CEO, Amit Mathradas said:
“This was a competitive process against a select group of enterprise-grade CX providers, and we earned it on the strength of our proof of concept and our delivery and execution capabilities.”
Mathradas later clarified during the call that “the award has been for the CCaaS portion of the business.”
A $100M Fortune 100 CCaaS Win, With Google in the Middle
Five9 described the customer as a Fortune 100 financial services organization undertaking a broader cloud migration. It will use Five9 as a core CX platform, with Google and a leading global systems integrator supporting the project.
The deal is notable for several reasons. First, it is one of the first large transactions through Google Cloud Marketplace. Second, it is a sizeable enterprise CCaaS win in a highly regulated sector where vendors must demonstrate more than a convincing AI demo.
Financial services organizations need reliable voice infrastructure, governance, integrations, compliance controls, and workable escalation routes to human agents. Five9 believes these requirements play to its strengths.
Mathradas said the company is focused on “complex, high-value integrations where reliability, governance, AI, digital workflows, data integrations, and human agents all need to work together in production.”
The point around working together in production is interesting. Indeed, many enterprises have spent the past two years experimenting with generative AI and AI agents. Moving those tools into live customer interactions, especially voice interactions, is another matter entirely.
While the call made it clear that this was a CCaaS deal, Mathradas also implied that it could evolve to include further Five9 features, such as the company’s voice AI agents.
If this were to materialize, the cloud element could be crucial. Mathradas suggested that businesses looking to run agentic voice AI at scale may find their on-premises contact center infrastructure wanting:
“When customers come to us and they deploy AI, particularly voice AI, on-prem, the architecture of on-prem is not specifically built to go run agentic voice at its best output.”
“In some cases, that actually forces customers to start taking a look at it migrating to cloud.”
AI Deployments Are Moving Faster
Five9 also reported that AI revenue grew 78% year-over-year in Q2, reaching approximately $39 million. That equates to an annual run rate of more than $150 million.
The vendor raised its full-year AI growth outlook to at least 60% year-over-year. But the more relevant detail for CX practitioners was why that growth accelerated.
According to Bryan Lee, CFO of Five9, several customers already in its backlog moved their deployments forward.
“This was one of those situations where the customer aligned really quickly internally on their end, and they came to us and said, ‘Let’s go. We can move much faster. We want to get this up and running,’” Lee said.
Five9 even expanded professional services capacity temporarily to meet earlier-than-expected customer demand for AI deployments. That suggests some organizations are moving beyond proof-of-concept purgatory, although it does not yet reveal how broad or deep those production deployments are.
Mathradas claimed that every million-dollar deal Five9 now closes has “100% attach of AI.” The company’s wider bet is that enterprises will buy AI as part of a platform combining voice, routing, data, automation, governance, and human agents.
The Real Challenge Is Repeatability
The Google partnership gives Five9 access to Google’s AI infrastructure and a potentially valuable route into cloud transformations. It also offers a chance to change how the vendor competes for enterprise deals.
Rebecca Wettemann, CEO and Principal Analyst at Valoir, believes the partnership will be “critical for Five9’s growth, and its AI strategy.
“The partnership lets Five9 leverage Google’s LLMs and compute without the R&D overhead of building from scratch, but it also gives it a distribution advantage it hasn’t fully leveraged yet.”
The Fortune 100 win suggests Five9 is starting to leverage that advantage. Whether it can repeat the approach is the more difficult question.
There is also another complication. AI can reduce the number of human agents enterprises require, placing pressure on traditional seat-based CCaaS revenue.
Five9 said it has not yet seen seat compression among its customers and is offering customers flexibility to shift their commitment between human agent seats and AI agents over three to five years.
Wettemann sees the issue as a central strategic test:
“Five9 needs to balance the seat counts and AI adoption carefully.”
For now, Five9 has a high-profile win, faster AI deployments, and a stronger Google Cloud story. The next step is showing that it can turn those ingredients into repeatable customer outcomes, not simply an impressive quarter.
