He spent more than three decades learning what happens beneath the software. Now Hitachi Vantara's CEO is betting that the most important promise in artificial intelligence is not magic, but machinery people can trust.

The storage veteran built a career in the unglamorous space between an idea and its arrival. At VAST Data, that instinct turned hardware logistics into someone else's specialty - and made room for a much larger software ambition.

The former infantry officer and networking inventor now runs a data company by one compact rule: prepare hard, decide before certainty arrives, and own what happens next.

Before AI needed data lakes, Jon Toor was already translating hard drives, virtualized I/O and object storage into reasons to care. His career is a lesson in staying with one difficult industry long enough to watch its quiet machinery become the main event.

For four decades, Mo Tahmasebi has worked in the least glamorous corner of technology: keeping important data available, recoverable and out of trouble. His playbook is equal parts engineering, thrift and the confidence to close a deal before the coffee gets cold.

After two decades spent deep in storage, product and transformation work, Panzura's CEO is betting that the least glamorous layer of enterprise technology may become AI's most important one.

ATTO does not make the computer or the storage. Tim Klein built a durable business in the vital space between them - one careful connection at a time.
Gal Naor is the co-founder and CEO of StorONE, a New York based enterprise storage company built on the idea that software, not more hardware, is the real bottleneck in data storage. He first made his mark in 2004 as co-founder of Storwize, which pioneered real-time enterprise storage compression and was acquired by IBM in 2010 for $140 million. Naor spent roughly six years and dozens of patents building StorONE's unified S1 storage engine, which provisions block, file and object storage from the same commodity drives at a fraction of legacy cost. He is known for a contrarian, efficiency-first philosophy and for steering StorONE to cash-flow positivity with an eye toward an eventual IPO.
Thomas Isakovich is the founder and CEO of Nimbus Data, the flash-storage company behind the ExaDrive DC100 - the 100-terabyte solid state drive that, years after its 2018 debut, still has no equal in capacity. He built and sold his first storage system as a teenager, launched TrueSAN Networks from his Stanford dorm room, watched it collapse in the dot-com bust at age 26, then started over with Nimbus Data and self-funded more than 90% of its growth into a profitable global business spanning 200 customers in 12 countries. He is a rare bird in Silicon Valley: a hardware founder who turned down the venture-capital playbook, kept the company his own, and went back to finish his Stanford degree purely because he missed thinking.

Hao Zhong is the CEO and Co-Founder of ScaleFlux, a San Jose-based fabless semiconductor company that builds computational storage drives and CXL memory solutions for cloud, AI, and data center workloads. With 20+ years in flash storage and LDPC technology — including stints at LSI, SandForce, and Fusion-io — Zhong co-founded ScaleFlux in 2014 to rethink what a storage device can do: compress data in hardware, cut write amplification, and deliver 4x effective capacity at roughly half the price of standard NVMe SSDs. ScaleFlux has raised $288M in funding and posted record-breaking growth in 2024.

Leander Yu is the founder and CEO of Graid Technology Inc., a Sunnyvale-based startup that invented the world's first GPU-accelerated RAID solution for NVMe SSDs - SupremeRAID. With over 25 years in the storage industry and a prior successful exit (Bigtera to Silicon Motion in 2017), Yu built Graid in 2019 to solve a fundamental bottleneck: traditional RAID controllers can't keep up with modern NVMe speeds. By offloading RAID computation to a GPU, SupremeRAID delivers up to 28 million IOPS and 260GB/s throughput from a single card. The company raised a $30M Series B in March 2025 led by Foxconn and CTBC joint venture, and signed a landmark licensing deal with Intel for VROC technology in late 2025.
