Dynatrace buys Arize in USD $915m AI observability deal

Dynatrace has agreed to acquire Arize in a USD $915 million cash-and-stock deal, one of the larger moves in the AI observability market.

The acquisition would combine software observability and AI model evaluation in a single offering, spanning development through live production systems. The aim is to bridge a divide between teams that test AI models and agents and those that run the applications and infrastructure beneath them.

AI observability has emerged as a fast-growing area as more companies move generative AI systems into customer-facing and internal operations. The field includes monitoring and assessing model behaviour before release and in production, including how large language models, agents and orchestration layers perform, and how that behaviour connects to application performance, infrastructure health and business processes.

Dynatrace said the category is projected to exceed USD $10 billion by 2030 and has become central to its growth plans. Customers increasingly want tools that can trace problems across the full stack, from prompts and model outputs to application failures and infrastructure bottlenecks.

Rick McConnell, Chief Executive Officer of Dynatrace, said the deal responds to that shift.

"AI is now moving into production at incredible speed, and the resulting AI Observability market opportunity is enormous. Dynatrace anticipates customers' needs at critical inflection points, and this is one of the most significant in our history," said Rick McConnell, Chief Executive Officer of Dynatrace.

He added: "Acquiring Arize advances our AI observability leadership, accelerates our roadmap, enhances our long-term growth profile, expands our reach with the developer community, and adds an incredible AI-first team to Dynatrace."

Arize has built its business around tools for AI observability and large language model evaluation. Dynatrace said Arize is used by both large enterprises and AI-focused developers, and cited its standing in open-source communities as part of the rationale for the acquisition.

The deal also reflects a wider contest among software vendors to secure positions in tooling for AI development and operations. As AI applications move beyond experiments, companies are looking for ways to measure output quality, detect hallucinations, and determine whether failures stem from model behaviour, prompts, orchestration logic or the systems supporting them.

Founders stay

Both of Arize's founders, Jason Lopatecki and Aparna Dhinakaran, are set to join Dynatrace when the deal closes. Lopatecki will continue to lead the Arize team and report directly to McConnell.

Lopatecki said the tie-up would connect AI evaluation with software observability in a single system.

"We founded Arize because AI teams needed a way to know their agents were actually working correctly, not just running," said Jason Lopatecki, Chief Executive Officer of Arize.

He added: "Joining Dynatrace will enable us to take that mission much further. Together, we can bring AI evaluation and software observability into an end-to-end system, enabling teams to build more ambitious AI applications faster. This is the kind of innovation that only happens when two companies with highly complementary solutions and go-to-market models come together, setting a new bar for what AI Observability can deliver for the entire industry."

Deal terms

Under the agreement, Dynatrace will pay USD $915 million, subject to customary adjustments. The consideration will include about USD $815 million in cash, along with replacement equity awards for Arize employees who join the company.

Dynatrace plans to fund the transaction through cash on hand and its existing credit facility. The company expects the acquisition to close later this quarter or early in its third quarter, subject to regulatory review and customary closing conditions.

The transaction is expected to add about 200 basis points to annual recurring revenue growth and reduce non-GAAP operating margin by 175 basis points in fiscal 2027. Dynatrace expects operating margin expansion from fiscal 2027 levels into fiscal 2028 and beyond, and does not expect a material effect on its second-quarter fiscal 2027 guidance or its ongoing share repurchase programme.

For Dynatrace, the acquisition provides a more direct route into the developer market as AI tooling choices increasingly begin with engineers rather than central IT teams. For Arize, the sale places its model evaluation and monitoring tools inside a larger software observability business that already serves enterprise customers at scale.

The combination would give customers a single set of tools spanning experimentation, deployment readiness, runtime evaluation and operational monitoring, alongside data analysis for AI workloads. It would also strengthen Dynatrace's position in a market where demand is growing for systems that can show not only whether an AI application is running, but whether it is producing reliable results.
