Hammerspace provides a file-system approach—built on the Linux kernel NFS client—to manage, move and orchestrate unstructured data across disparate locations so it is available when needed and out of the way when not. Its technology targets AI and other data-intensive use cases, and the company counts customers such as NVIDIA, Meta, Tesla, Palantir and the Department of Defense. Growth to date has been driven largely by word-of-mouth, and the startup positions its product as a faster alternative to traditional data-porting approaches. Hammerspace’s co-founder and CTO is the lead maintainer of the Linux NFS client, and CEO David Flynn’s background in flash computing influenced the product design. The company has signaled ambitions to go public—previously suggesting an IPO timeline of roughly two years out, dependent on market conditions. It will use part of the new funding to expand sales and marketing to accelerate adoption.
