NetApp to acquire AI storage startup PEAK:AIO in undisclosed deal

The deal targets a chronic AI bottleneck: storage systems that can't keep pace with sprawling GPU clusters.

• NetApp (NASDAQ: NTAP) announced on September 25, 2026 its intent to acquire PEAK:AIO, a Manchester, UK-based AI storage software startup, on undisclosed financial terms.
• Founded in 2021 by Mark Klarzynski and Eyal Lemberger, PEAK:AIO builds software-defined all-flash storage with a parallel NFS file system and metadata architecture, developed with input from Los Alamos National Laboratory and Carnegie Mellon University.
• NetApp plans to pair PEAK:AIO's technology with ONTAP by disaggregating metadata from data, letting metadata services scale independently to support trillions of files and exabyte-scale AI environments.
• PEAK:AIO had raised roughly $6.8-7 million in seed funding around October 2025, and the muted 0.36% move in NetApp's stock reflects a deal size analysts call immaterial against NetApp's $300.7 million in quarterly free cash flow.
• PEAK:AIO's parallel-NFS approach is pitched as an alternative to Lustre-style parallel file systems that have long dominated high-performance AI storage.
• The transaction remains subject to customary closing conditions and regulatory approvals; public filings around the announcement show only routine insider Form 4s, not an 8-K confirming a signed, definitive agreement.
• As GPU clusters scale faster than traditional storage architectures can follow, storage vendors are increasingly using small tuck-in acquisitions like this one to buy AI-ready capability rather than build it from scratch.
