Occuspace
Occuspace is a smart-building company that measures how physical spaces are actually used. Its plug-in sensors passively read ambient Bluetooth and WiFi signals - never cameras or personal data - to estimate real-time occupancy, foot traffic and dwell time, then feed the numbers into a dashboard and the free Waitz app. Founded in 2017 by three UC San Diego roommates, it now serves 100+ university campuses plus corporate and federal customers, helping them cut wasted space, save energy and plan facilities from data instead of guesswork.
Density
Density is a San Francisco-based people-analytics company that builds privacy-first sensors and software to measure how offices, buildings, and other spaces are actually used in real time. Founded in 2014 by Andrew Farah, it pairs radar and depth-sensing hardware with its Atlas analytics platform to help enterprises cut real estate costs, plan hybrid workplaces, and understand utilization without cameras or personally identifiable data. Backed by more than $225 million in funding and a $1.05 billion valuation, Density serves Fortune 500 customers across dozens of countries.
Ariadne
Ariadne is a Munich-based, privacy-first physical-world analytics company that measures how people move through real spaces - shops, malls, train stations and airports - without cameras or facial recognition. Its patented Hybrid Fusion technology pairs anonymous phone-signal sensing with Time-of-Flight depth sensing to deliver up to 99% accurate people counting and sub-meter flow analytics, all GDPR-native and EU AI Act ready. Founded by two Greek engineers who met at the Technical University of Munich, Ariadne has installed more than 1,000 sensors across 800+ locations in 32+ countries, serving customers like San Diego International Airport, IKEA, MediaMarkt and Deutsche Bahn.
Georgios Pipelidis
Georgios Pipelidis is the co-founder and CEO of Ariadne, a Munich-born company that turns the anonymous radio signals leaking from smartphones into privacy-first analytics about how people move through airports, stores and stations - no cameras, no apps, no network connection required. A computer scientist with a PhD in artificial intelligence from the Technical University of Munich, he turned an academic project on indoor positioning - one that beat Google, IBM, Samsung, Cisco and Sony at a 2018 global competition - into a company operating sensors in hundreds of locations worldwide, backed by a $7M Series A.
Andrew Farah
Andrew Farah is the CEO and co-founder of Density, a San Francisco-based company that builds anonymous, privacy-first sensors to measure how physical spaces are actually used. What started in 2014 as a fix for a coffee shop line problem in upstate New York has grown into a $1B+ enterprise used by Fortune 500 companies across 1.25 billion square feet globally. Farah has raised over $217 million from investors including Kleiner Perkins, Founders Fund, and Altimeter Capital, and has built Density into what he calls 'Google Analytics for the built world.'
