Five9 Q2 2026 Results: AI Revenue Jumps 78% YoY as Total Revenue Grows 10%

On an August 6 earnings call, Five9 announced a total Q2 2026 revenue of $312 million (10% YoY growth), a third consecutive quarter of accelerated subscription revenue growth (14% YoY), and a 78% YoY AI revenue growth. AI now makes up 15% of Five9 subscription revenue, up 6 points from 9% a year ago.

Additional Q2 highlights include a $100 million deal with a Fortune 100 financial services firm, 12% cloud communications revenue growth, and 9% revenue growth from voice solutions. In terms of Q2 innovation, Five9 introduced agentic voice AI and launched AI Agent Studio.

Full Year 2026 guidance adjustments show that Five9 continues to grow top-line revenue growth while ramping up AI adoption faster than expected. While FY 2026 revenue guidance rose slightly to a midpoint of $1.266 billion, FY revenue growth from AI is expected to increase over 40% to at least 60% YoY. The rapid AI deployments required Five9 to temporarily expand professional services capacity, while expenses related to organizational restructuring also rose temporarily. As a result, Five9’s adjusted gross margins fell from 63% to 61% during the second quarter.

Q2 marks our third consecutive quarter of accelerating subscription revenue growth, with AI revenue accelerating even faster, and further evidence that our focused execution is producing results. Closing a 9-figure TCV agreement through the Google Marketplace and launching Five9 Voice AI Agents in the same quarter underscore the breadth of our platform and the strength of our market position.

The next phase of customer experience will require more than maintaining a traditional contact center. It will require bringing voice, digital, AI, data, and human workflows together into one platform.

What The Q2 2026 Results Mean For Five9

2025-2026 has been a time of heavy transformation at Five9, and the second quarter of 2026 was no exception.

These strategic transformations are led by Amit Mathradas, who took over as Five9 CEO in February of 2026. What’s interesting here is that Mathradas comes from the world of business process automation and enterprise GTM, not strictly contact centers. This trajectory matters because Mathradas is positioning the contact center as one of many business processes, not a self-contained, standalone solution with separate metrics, software, and buyers.

Mathradas’ thesis that the contact center should integrate with and optimize all other business processes is a break from point-solution providers that position AI primarily as a cost reduction tool. Instead, Mathradas wants Five9 to create outcomes that positively impact how an entire organization runs by coordinating processes across systems.

Five9’s advantage is that because it owns the coordination layer (routing, telephony, integrations) it’s genuinely capable of enterprise business process orchestration at scale. This reframing also lets Five9 market not only to CCaaS buyers, but to larger-budgeted enterprise transformation and IT buyers.

To help execute this vision, Mathradas made significant leadership changes at Five9 during Q2. He hired Jay Lee as Chief Marketing and Growth Officer, appointed fellow Nintex alum Niranjan Vijayaragavan as CTO, announced Rob Hornish as Chief Sales Officer, and made Workday alum Sven Linsmaier EVP of Transformation and Strategy.

Five9’s January expanded partnership and joint Enterprise CX AI solution with Google Cloud is a key part of the Q2 story, as well. Importantly, this partnership means Five9’s CCaaS/CX platform is now listed on the Google Cloud Marketplace: a move that significantly simplifies and expands enterprise procurement.

This quarter’s Fortune $100 million win is one of Five9’s first major deals to run through the Google Cloud Marketplace, strengthening Mathradas’ argument that enterprises see CCaaS and CX solutions as investments in company-wide transformation, not simply technology.

Whether this kind of high-level deal through Google Cloud Marketplace is repeatable or a one-off remains to be seen.

Five9: From CCaaS Platform To Enterprise IT Partner 

The results from the second quarter of 2026 show that Five9 is well on its way to moving from a standalone CCaaS/CX platform to a transformational IT and automation partner (especially for enterprises in heavily-regulated sectors.)

Five9 also restructured its R&D organization during Q2, consolidating product engineering and management, AI automation, and architecture under one leadership structure (led by new CTO Niranjan Vijayaragavan) to speed up delivery across the product lifecycle.

Underpinning all of this is Five9’s shift to a revenue-commitment model over pure per-seat licensing (almost essential move, given AI’s massive impact on per-seat revenue.) Customers, including Five9’s star Fortune 100 financial services firm, commit to a revenue level over 3-5 years and gain the flexibility to shift their spend between human agent seats and AI agents as needs evolve over time.

The revenue-commitment approach is, ideally, a win-win: enterprises get budget predictability and flexibility, and Five9 secures multi-year revenue.

Later this week, I’ll be on a call with fellow analysts and Five9 leadership discussing the company’s strategy and Mathradas’ “less narrative, more evidence” approach. Stay tuned for further thoughts.
