Dynatrace (NYSE: DT) has signed a definitive agreement to acquire Arize. The deal is valued at $915 million and, according to the company’s announcement, consists of roughly $815 million in cash plus replacement equity awards for Arize employees joining Dynatrace. The transaction is to be funded from cash on hand and/or the existing credit facility.
For Dynatrace — founded in Linz in 2005 by Bernd Greifeneder, today headquartered in the greater Boston area and listed on the New York Stock Exchange — this is the biggest purchase the company has ever made. Previous acquisitions such as Bindplane (April 2026), Metis, Runecast or Rookout (2023) were in far smaller territory; in most cases the price was never disclosed at all.
What Arize does
Arize was founded in 2020, is based in the San Francisco Bay Area and offers a platform that lets engineering teams test, evaluate and monitor the behaviour of machine learning models, large language models and AI agents in production — for instance to detect hallucinations, measure drops in output quality or spot data drift. The company is also known for its open-source tool Phoenix and the developer community around it.
In total, Arize had raised around $131 million in venture capital, according to Tracxn data. Its largest round to date was a $70 million Series C in February 2025 led by Adams Street Partners, with participation from Microsoft’s venture arm M12, OMERS Ventures, Sinewave Ventures as well as industry neighbours Datadog and PagerDuty. Existing investors include Foundation Capital, Battery Ventures and TCV.
The logic behind the deal
Dynatrace argues that AI software delivery currently happens in two separate worlds: AI teams evaluate model and agent behaviour with one set of tools, while the teams running applications and infrastructure work with another. When output quality slips or a customer transaction fails, the cause can sit anywhere between the prompt and the infrastructure. With Arize, Dynatrace wants to close that gap and connect pre-release evaluation with production monitoring — including GPU utilisation and infrastructure health.
“AI is now moving into production at incredible speed, and the resulting AI Observability market opportunity is enormous,” Dynatrace CEO Rick McConnell is quoted as saying in the announcement. The acquisition, he says, accelerates the roadmap and extends the company’s reach into the developer community. Arize CEO Jason Lopatecki points to teams getting AI evaluation and software observability as one end-to-end system.
Dynatrace puts the AI observability market at more than $10 billion by 2030 — a projection that comes from the buyer itself and should be read accordingly.
Timeline and financial impact
The transaction is expected to close later this quarter or early in Dynatrace’s third fiscal quarter, subject to regulatory review. Arize’s two founders, Jason Lopatecki and Aparna Dhinakaran, will join Dynatrace at closing; Lopatecki will continue to lead the Arize team and report directly to McConnell.
On the numbers, Dynatrace expects the deal to add roughly 200 basis points to ARR growth in fiscal 2027 while diluting the non-GAAP operating margin by about 175 basis points. Second-quarter guidance and the ongoing share buyback programme remain unaffected, according to the company. J.P. Morgan Securities and Goodwin Procter advised Dynatrace; Qatalyst Partners and DLA Piper advised Arize.
The Austrian angle
In fiscal 2026, Dynatrace passed the $2 billion mark in annual recurring revenue for the first time ($2.054 billion, up 18 percent) and employs around 5,600 people worldwide. Linz remains the engineering headquarters: the campus there is being expanded to roughly 23,000 square metres for up to 1,500 developers and specialists. Whether and how the Arize acquisition will affect the site, the company has so far left open.
The stock rose sharply after first-quarter fiscal 2027 results in early August, but still trades below its highs on a year-over-year basis.
