Dynatrace to buy Arize for $915 million in AI observability push

Dynatrace agreed to buy AI observability company Arize for $915 million, about $815 million in cash, betting on a market the software maker expects to exceed $10 billion by 2030.

"This is not a point solution," Rick McConnell, chief executive officer of Dynatrace, said. "It is a portfolio expansion that positions Dynatrace to better capture a greater share of AI spending in this rapidly emerging category."

The transaction, expected to close by the end of September or early October, includes replacement equity awards for Arize employees who join Dynatrace. Dynatrace said it has sufficient cash on hand and access to its existing credit facility to fund the deal, and its share repurchase plans are unchanged. Arize brings roughly 200 customers, with 20 percent to 30 percent overlapping Dynatrace's base, and its open-source Phoenix platform records millions of monthly downloads.

Dynatrace expects the acquisition to add about 200 basis points to its annual recurring revenue growth in fiscal 2027, or roughly $40 million, while diluting non-GAAP operating margin by about 175 basis points. The company previously guided for fiscal 2027 ARR growth of 15.5 percent to 16.5 percent.

Why AI Observability Matters

McConnell said enterprises need to assess whether AI systems are functioning, whether their outputs are accurate and trustworthy, and whether agentic systems deliver their intended outcomes. AI systems can fail differently than traditional software, he said, including through plausible but incorrect, biased or factually wrong outputs that may not generate conventional infrastructure alerts.

Arize adds capabilities in AI and agent evaluation, experimentation and agentic workflow optimization across development and production. Those capabilities complement Dynatrace's existing offerings in application and infrastructure observability, model performance, AI usage and cost, and business impact. Dynatrace had been investing internally in AI observability for roughly 18 months, and McConnell said the acquisition would accelerate its roadmap by adding deeper capabilities in LLM experimentation, evaluations and observability for issues such as model drift and hallucinations.

The deal shows how quickly AI monitoring has become a battleground in enterprise software. Datadog, Dynatrace's closest rival in observability, has pushed deeper into AI monitoring, while Fortinet this week acquired AI security company Virtue AI. The scramble reflects a broader shift as enterprises move observability earlier in the software development cycle, with developers increasingly influential in buying decisions.

Developer Reach and Financial Impact

A central element of the deal is Arize's reach among AI developers through its open-source Phoenix platform, which McConnell said has millions of monthly downloads and is used for LLM evaluations. Arize also maintains an open-source standard called OpenInference. Dynatrace expects the acquisition to extend its reach into developer-led buying motions and AI-native workloads.

Chief Financial Officer Jim Benson said Arize is a small but rapidly growing business. Dynatrace intends initially to let Arize operate with substantial independence rather than immediately fully integrating its technology, with Arize co-founder Jason expected to join Dynatrace's leadership team and lead Arize as a business unit. The company expects to eventually integrate Arize into its Dynatrace Platform Subscription offering.

Benson said Arize's revenue-recognition model is similar to Dynatrace's, with annual contracts, ratable revenue recognition and advance billing. The company does not expect a material impact on its second-quarter guidance because of the anticipated close timing, and plans to provide additional information on Arize's growth profile during its second-quarter earnings call in early November.

Dynatrace executives said the acquisition is designed to create cross-sell and upsell opportunities in both customer bases while adding access to AI-native companies and the broader developer community. The companies already share customers across automotive, communications, e-commerce and financial services.
