Lightbits develops a datacenter software with “hardware acceleration” that helps connect storage servers with applications, according to Kirzner. The technology is already deployed at the datacenter of some industry heavyweights, he said. Kirzner declined to name these companies.

The company got its start when Israeli serial entrepreneur Avigdor Willenz approached Kirzner with the vision of redesigning databases and data storage. Willenz previously founded Galileo Technologies Ltd., sold to Marvell Technology Group Ltd. in 2001 for $2.7 billion, and Annapurna Labs, sold in 2015 to Amazon. He is also a prolific investor, sitting on the boards of companies including artificial intelligence chip developer Habana Labs Ltd. and real estate data startup Localize.city.

Willenz now serves as a “hyper-active chairman” at Lightbits, and is deeply involved in the company’s operation and vision, Kirzner said in a Monday interview with Calcalist.

Kirzner was one of the founders of network processors provider Wintegra Inc., sold in 2010 to PMC-Sierra Inc. Willenz was Wintegra’s first investor. Lightbits co-founders Ofir Efrati and Muli Ben-Yehuda serve as vice president of engineering and chief technology officer, respectively

From the start, Kirzner said, Lightbits was in contact with hyperscalers–giant tech companies such as Amazon, Facebook, and Google–to better understand their needs. The uptake from these conversations, according to Kirzner—the few existing datacenter technologies are not suited for cloud-native applications, and limit scaling.

The result is a software layer that can be installed on existing servers that connects flash storage to applications at a high speed. There’s also an option for an additional acceleration card.

“To get a standard accepted often takes years, but we did it in a year, and it’s not just because industry giants helped push it,” Kirzner said.
