Azul appoints Matt Camassa as Chief Revenue Officer.

Azul appoints Matt Camassa as Chief Revenue Officer. SINGAPORE, October 8, 2026: Enterprise Java company Azul has appointed Matt Camassa as Chief Revenue Officer, putting him in charge of the company's global revenue organisation as it looks to expand adoption of its AI-first Java platform across enterprise customers. Camassa will oversee sales, solution engineering, partners, customer success and operations worldwide, with a mandate to accelerate enterprise growth and broaden Azul's routes to market across North America, EMEA, APAC and Latin America. The appointment comes as enterprises face increasing pressure to improve performance, security and cost efficiency across Java environments, particularly as AI workloads place additional demands on existing technology estates. Camassa brings more than 20 years of experience building and scaling global enterprise software sales organisations. He previously served as CRO at TeleSign, where he helped scale the business through a period of rapid growth before its acquisition by BICS in 2017. He later led worldwide sales at fraud-prevention company Sift, where Azul said he oversaw a multi-year growth phase with strong net revenue retention. Most recently, Camassa was an operating partner at Diversis Capital, having earlier served as an executive in residence at K1 Investment Management. In those roles, he worked on go-to-market strategy, advised portfolio companies and held several interim CRO positions. As CRO, Camassa will lead the teams responsible for commercialising Azul's portfolio, which includes Azul Prime, Azul Core, Azul Intelligence Cloud, Azul Payara Micro and Azul Payara Server. Camassa said enterprises are increasingly looking for platforms that can address pressing operational challenges as AI places greater pressure on underlying systems. "Azul is in a unique position, providing a complete platform that makes Java faster, more secure and less expensive to run," he said. Azul Co-Founder and CEO Scott Sellers said Camassa's experience in building global revenue organisations and selling mission-critical software to large enterprises made him well suited to the role. "Azul has grown from a Java runtime leader into a full AI-first Java platform, and Matt brings an exceptionally strong track record of success to our executive team," Sellers said. Camassa's appointment adds a senior commercial leader to Azul's executive team at a time when enterprise infrastructure vendors are repositioning around the operational demands created by AI adoption.

Azul launches AI assistant for Java security checks.

Azul launches AI assistant for Java security checks. Thu, 24th Sep 2026 (Today) Azul has launched an AI Assistant for its Intelligence Cloud platform, aimed at IT, DevOps and security teams managing Java environments. The tool lets users ask natural-language questions about live runtime data to identify licensing and security risks across production Java estates. It is designed to show where Oracle Java is still running, which Java versions remain unpatched, and what code is unused and could be removed. Built into Azul's existing cloud service, it maintains a current record of running Java Virtual Machines and code use in production. The launch comes as the time between disclosure of software flaws and their exploitation continues to shrink. Azul cited research and public disclosures suggesting artificial intelligence is accelerating vulnerability discovery and exploit development, increasing pressure on organisations to know exactly what is active in their systems. Azul said many organisations still rely on static asset management reports and code-scanning tools to track Java use. But those records can quickly become outdated as Java Virtual Machines are deployed, patched, changed or retired across on-premises systems, cloud infrastructure and containers. That can create several areas of exposure, including unlicensed or unsupported Java distributions, systems running vulnerable versions, and old code that teams continue to maintain because they cannot tell whether it is still used in production. The new assistant sits on top of Azul's JVM Inventory and Code Inventory services. These maintain a live catalogue of Java Virtual Machines and a runtime record of which code is actually executed, rather than simply provisioned. Users can query the system in plain language instead of building reports or writing technical queries. That allows teams to investigate issues as they arise and immediately follow up with further questions based on current production data. Broader users Azul is also positioning the assistant for non-technical users who need information from Java estates for compliance, finance or governance decisions. It said the tool could help a compliance officer preparing for an audit, a Chief Financial Officer assessing Oracle licensing exposure, or a Chief Information Security Officer reporting current risk to a board. Managed service providers and systems integrators could also use the assistant as part of ongoing Java management work for clients, rather than treating such reviews as one-off consulting projects. Azul said the assistant does not take action in customer environments. It answers questions using runtime data already collected from live production systems, with no added performance overhead. Industry view William Fellows, Research Director at 451 Research by S&P Global Energy, said the launch addresses a longstanding visibility problem for organisations with large and ageing Java estates. "Azul is extending its Intelligence Cloud platform with a new AI Assistant that gives enterprises a natural language interface into their Java runtime environments, to help identify unused code, redundant JVMs and untracked deployments. For organisations with decades of Java debt, the tool addresses a gap that has not yet been targeted at this level," said Fellows. Azul said the assistant can work across Java environments regardless of vendor, age or application size. It also retains historical component and code-use records, allowing users to ask not only what is running now, but what ran previously. That means teams can identify when an Oracle JVM was last active, what code has executed over time, and which code paths may no longer be needed. Azul argues this provides a more current picture than scheduled scans and summary reports that may already be outdated by the time they are reviewed. Scott Sellers, Co-Founder and Chief Executive Officer of Azul, said the pace of risk in Java environments had changed. "For years, enterprises have built dashboards and reports to understand what's actually running in their Java estate, but by the time a report gets properly summarized and reviewed, the risk it describes has often already changed," said Sellers. "That used to be a productivity problem. Now that AI can find and weaponise a vulnerability in hours instead of weeks, it's a business risk - for security, for compliance and for the licensing exposure that shows up in an audit. The Azul Intelligence Cloud AI Assistant lets IT and security teams ask a direct question, in plain language, and get an answer grounded in what's actually running in production right now, as well as query historical information for further analysis," said Sellers.

Azul appoints Kenny Johnston as CPO to lead AI-first Java platform strategy

Azul, an enterprise Java platform provider, has appointed Kenny Johnston as chief product officer. Johnston previously served as chief product and technology officer at Luciq, an AI observability platform, where he led product, design, customer success, and engineering functions. Earlier in his career, Johnston held senior product management roles at GitLab, where he led operations and infrastructure products, and at Rackspace, where he more than tripled annual revenue for Rackspace Private Cloud. At Azul, Johnston will lead product strategy across the company's AI-first Java platform, including Azul Prime, Azul Core, Azul Intelligence Cloud, and Azul Payara products. His focus will be addressing the demands AI places on enterprise Java systems, including cost, performance, security, modernisation, and productivity. Azul serves 37% of the Fortune 100 companies.

Azul appoints Kenny Johnston as Chief Product Officer.

Azul appoints Kenny Johnston as Chief Product Officer. August 11, 2026 Azul has announced the appointment of Kenny Johnston as Chief Product Officer. The appointment comes following the retirement of Martin Van Ryswyk, after five years in the role. Johnston joins from Luciq, where he was Chief Product and Technology Officer. He has over two decades of experience in technology. His recent roles have seen him gain deep experience of building agentic, AI-powered enterprise DevOps and observability tools and platforms. At Azul, he will be responsible for leading the product strategy and execution of Azul's AI-first Java Platform. Moreover, the platform supports, secures, and maintains Java ecosystems that organisations have invested in. It consists of Azul Prime, Azul Core, Azul Intelligence Cloud, Azul Payara Micro and Azul Payara Server. Azul Payara Micro and Azul Payara Server were added to the Azul platform through Azul's December 2025 acquisition of Payara. Johnston will advance the roadmap to meet AI demands on Java estates. He will tackle cost, performance, security, modernization, and productivity head-on. AI pressures now drive every initiative in the enterprise Java landscape. Scott Sellers, Co-Founder and CEO, said, "Kenny's track record of scaling enterprise product organisations to build products that address business-critical use cases makes him exactly the right product leader as AI reshapes the performance, security and cost demands of every enterprise Java estate. "Under his leadership, we're focused on continuing to build out our AI-first Java platform and helping drive Azul into its next phase of growth." Who is Kenny Johnston. Johnston spent four years at Luciq, first as VP of Product and then as Chief Product and Technology Officer. He led global teams across Customer Success, Support, Product, Design and Engineering functions. He was responsible for delivering agentic observability built for enterprise mobile developers to help their apps meet the increasingly high bar that mobile users expect. Johnston helped the development function transform using Agentic SDLC with AI tools like Claude Code, FigmaMake, CodeRabbit & HumanLayer. Before Luciq, he was the Senior Director of Product Management at GitLab for nearly four years, leading a globally distributed Product Management function. He also held product leadership positions at both Rackspace and Hewlett-Packard. At Rackspace, he served as director of product management for Rackspace Private Cloud. More than tripling annual revenue and earning recognition as HPE's Global Service Provider Partner of the Year. At HP, he managed strategy development and feature prioritization for HP Helion - OpenStack Distribution. Johnston said, "Java is the backbone of the world's most critical enterprise systems, and AI is amplifying the pressure on all of it. The opportunity is to bring an AI-first, DevOps-centric vision to how Java is developed, deployed, secured and monitored in the enterprise. "I've spent my career helping world-class teams accelerate through transformative moments like this, and I'm excited to build on the strong foundation Azul has already established." Enterprise times: what does this mean. Johnston's arrival gives Azul a product leader with relevant experience at the point where Java, AI and enterprise modernisation are converging. Azul is arguing that Java will remain central to production AI, not just legacy systems. With Johnston's background in DevOps, observability and agentic AI, this should help connect that message to practical product execution. The key test will be whether Azul can turn its AI-first Java platform into measurable benefits around performance, security and cloud cost. If Johnston succeeds, Azul could strengthen its position as enterprises reassess Java estates for the AI era. Looking forward, Azul's product roadmap will focus on alleviating the pressures AI places on enterprise Java: absorbing AI workload demand and optimising cloud cost (Azul Prime), narrowing the AI-era security and patch-velocity gap (Azul Core), enabling AI-driven modernisation (Azul Intelligence Cloud, Azul Payara), and giving AI-modernised workloads the scalability, security and automation they need (all Azul products).
