Artificial intelligence services at their heart are massive data plays: You need data — a lot of it — to build the models, and then the models need efficient ways to ingest and output data to work.
A company called Hammerspace has built a system to help AI and other organizations tap into data troves with minimal heavy lifting, and it’s been seeing impressive adoption. Now, with customers including Meta and the Department of Defense, as well as other very recognizable names, Hammerspace is announcing $100 million in funding to expand its business.
The funding is being described as a “strategic venture round,” and it values Hammerspace at over $500 million, sources close to the company told TechCrunch. Its backers include Altimeter Capital and ARK Invest, alongside strategic investors that are not being disclosed. The investors are being described as “highly participatory.”
The funding is notable because it points to the ecosystem developing around the value that the market sees in AI companies, which are raising billions of dollars both to build their capital-intensive businesses and meet massive demand.
But as Jamin Ball, a partner at Altimeter, noted, “You don’t have an AI strategy without a data strategy.” So a company that is building a platform to enable that data strategy can itself become very valuable, too.
Hammerspace said much of its growth so far has been through word of mouth. It will be using a portion of this funding to expand on that more proactively with sales and marketing.
Hammerspace previously raised $56 million from Prosperity7 Ventures (the venture arm of Saudi Aramco), ARK Invest, Pier 88 Hedge Fund, and other unnamed investors. Prior to that, it was self-funded by its CEO and co-founder David Flynn, the pioneer technologist known for his early work on Linux, supercomputers, and flash computing.
There are a vast number of companies that have set out to plug the big gap that exists in the data market today. “Vast” is an operative word here, as it is one of the companies that competes with Hammerspace, along with Dell, Pure Storage, Weka, and many others in the worlds of data orchestration, file management, data pipeline, and data management.
That gap goes something like this: The apps and other digital services we use to work and do everything else in life these days produce a lot of potentially valuable data. But data troves exist in silos — they’re fragmented, stored across multiple (competing) clouds and other environments, and are often unstructured. That makes them a challenge to use.
This gap applies across a wide range of enterprise use cases, but perhaps the biggest of these at the moment is AI.
“AI has been the perfect storm for needing what I have built,” Flynn said in an interview.
Hammerspace, as we’ve noted before, is named after the concept first coined from cartoons and comics, where characters pull objects they need out of thin air.
This is, in effect, what Hammerspace does. The startup provides a way of making large amounts of data, regardless of where it lives or how it is used, accessible and available to an organization just when they need it, and keeping it out of the way when they do not.
As Flynn describes it, typically the way that enterprises would have worked with data would be to port it from wherever it is to where it needs to be processed. “You need to install stuff on every system,” he said. “It’s a mess.”
It’s also slow. “The AI arms race is such a sprint,” he said. With “time to value” now a key priority for these companies, Hammerspace is signing up a lot of customers that are anxious about idle time.
Flynn’s background in flash computing is central to Hammerspace’s breakthrough. Built on Linux, ubiquitous in the database world, he could see that the key to organizing data across disparate locations was to create a file system to do so.
The heart of this is the Linux kernel NFS client, ubiquitous across many of the data systems. Hammerspace’s co-founder and CTO, Trond Myklebust, was the lead developer of the Linux kernel NFS client, and the startup remains its lead maintainer. The “file system” that the company has built for managing, moving, and orchestrating data is based on a particular implementation in Linux that taps this. What it does, Flynn said, “is unique across the industry.”
Longer term, Flynn said last year that Hammerspace may go public as early as this year. That timeline has changed now but the direction has not. “Yes, IPO is absolutely the Hammerspace intended strategy,” Flynn said. “We likely are still approximately two years out (dependent on market conditions).”
Updated to note that Nvidia, Palantir and Tesla are not customers of Hammerspace; they are past investments of Altimeter.
