Higher Ground LLC
Higher Ground LLC is a Palo Alto hardware startup that builds compact, secure satellite communication and navigation devices. Its flagship SatPaq turned a smartphone into a two-way satellite messenger by talking to geostationary Intelsat Galaxy satellites, and the company has since pivoted its expertise toward defense and government work - most notably GEOFix, a non-jammable backup to GPS. Led by founder and CEO Rob Reis, the company holds dozens of patents and counts the U.S. Department of Defense, DHS, NASA and the FAA among its customers.
Mattermost
Mattermost is an open-source, self-hostable collaboration platform built for organizations that cannot put their conversations in someone else's cloud. Started as a game studio's internal chat tool and open-sourced in 2015, it grew into the leading self-hosted alternative to Slack and Microsoft Teams, combining channel messaging, voice and screen sharing, incident-response Playbooks, and integrated AI agents. Its customers skew toward defense, government, financial services, and technology organizations - from the U.S. Air Force to Uber - that need data sovereignty, air-gapped deployment, and government-grade security.
Tellescope
Tellescope is a HIPAA-compliant digital health platform that unifies patient communication, intake, scheduling, and workflow automation into a single, developer-friendly system. Built for digital health startups and modern clinics, it lets care teams reach patients across SMS, email, chat, and video, automate repetitive workflows without code, and plug into EHRs and clinical tools through an API-first architecture - so teams can launch faster and scale personalized care without stitching together generic sales software.
Vocera Communications, now part of Stryker
Vocera Communications builds the hands-free, voice-controlled communication tools that hospitals use to connect care teams in real time. Founded in 2000 and inspired by the Star Trek communicator badge, Vocera's wearable Badge and Smartbadge, plus its Vina app and Engage intelligent-workflow platform, let clinicians reach a colleague by name, role, or group with a single voice command. Used in roughly 2,300 facilities worldwide and integrated with more than 150 clinical and operational systems, Vocera went public in 2012 (NYSE: VCRA) and was acquired by medical-technology giant Stryker in February 2022 for about $3.09 billion, where it now anchors Stryker's digital care coordination portfolio.
