Top Tech Startups in Santa Clara, CA in 2026

Today, there's more data and users outside the enterprise than inside, causing the network perimeter as we know it to dissolve. We realized a new perimeter was needed, one that is built in the cloud and follows and protects data wherever it goes, so we started Netskope to redefine Cloud, Network and Data Security. Since 2012, we have built the market-leading cloud security company and an award-winning culture powered by hundreds of employees spread across offices in Santa Clara, St. Louis, Bangalore, London, Melbourne, and Tokyo. Our core values are openness, honesty, and transparency, and we purposely developed our open desk layouts and large meeting spaces to support and promote partnerships, collaboration, and teamwork. From catered lunches and office celebrations to employee recognition events (pre and hopefully post-Covid) and social professional groups such as the Awesome Women of Netskope (AWON), we strive to keep work fun, supportive and interactive. Visit us at Netskope Careers. Follow us on LinkedIn and Twitter @Netskope for more updates.

The software used to manage networks hasn’t kept up with the dramatic expansion of networks themselves. The Forward Networks solution is designed to help network teams eliminate network outages and reduce time to remediate errors. Its platform enables engineers and operators to visualize and search complex networks, debug configuration problems, verify network-wide policy implementations, and predict network behavior prior to deploying changes. Forward Networks builds a software replica of an entire network to analyze its behavior. Using the network copy, the software traces, indexes, and stores the collected data, monitoring things like end-to-end behavior, verification of the network’s forwarding behavior and security posture, and close monitoring of configuration changes.

Atomic Machines is doing something truly epic: inventing the future of how things are made. And a glorious future it will be. We envision an era of atomically precise manufacturing (APM), in which everything is made by assembling matter at the molecular level, making anything from its digital description, blurring the line between bits and atoms. Our first move on the long journey to this APM future is in the realm of microfabrication, making mechanical devices with features sized in the single-digit microns scale. Our fabrication technology will be full-stack, 100% automated and data-driven, and we’re expanding the engineering team now to take it to commercial reality. We have engineering offices in Berkeley and Santa Clara, CA. We are well funded, and our leadership has a long track record of success. We have successfully developed multiple prototype generations of our first MEMS device and are benefitting directly from the direct-write nature of our fabrication technology, going from bits to atoms in hours, not months or years.
