RetailNext counts the customers your till never sees
A receipt tells you who bought. RetailNext measures who walked in, where they went, and what happened before they left - giving store operators a better way to judge performance.
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.
