OneLayer knows what your SIM card is hiding
A private cellular network can recognize a SIM and still miss the machinery behind it. OneLayer turns that awkward gap into a business in device visibility, automated onboarding and security.
SHIELD
SHIELD is a device-first fraud intelligence platform that helps online businesses stop fraud, build trust, and drive growth.

Johan Brissmyr
Johan Brissmyr is the CEO and co-founder of Castle, a security company that helps online businesses detect fraud, bots, and account takeover in real time. A computer scientist from Lund University, he started building web products in Malmo, Sweden before moving to Silicon Valley through Y Combinator and relocating the company to New York. Castle grew out of a password-storage side project that revealed a bigger opportunity in behavioral risk scoring, and today combines device fingerprinting, behavioral signals, and analytics into APIs used by companies of many sizes.
CUJO AI
CUJO AI is a network intelligence and cybersecurity company that turns raw broadband network data into actionable insights for internet and mobile operators. Founded in 2015, its cloud-native platform uses machine learning to identify and classify connected devices, block malware and phishing in real time, and deliver digital life protection, parental controls and network analytics. Delivered as software to carriers rather than as consumer hardware, CUJO AI reaches more than 60 million homes and monitors billions of connected devices for operators including Comcast, Charter, TELUS, Sky and Rogers.
Incognia
Incognia is a location identity and fraud prevention company that uses device intelligence, location behavioral analytics, and AI to help platform businesses — from food delivery to financial services — detect fraud without compromising the user experience. By processing signals from GPS, Wi-Fi, and Bluetooth without capturing PII, Incognia identifies legitimate users from fraudsters across multiple devices with 99.999999% accuracy, a 0.0001% false-positive rate, and no friction for genuine users. Deployed on over 200 million smartphones and protecting nearly 1 billion devices, Incognia has become the go-to fraud layer for platforms like Grubhub, Delivery Hero, and Upwork.
Andre Ferraz
Andre Ferraz is the co-founder and CEO of Incognia, a Palo Alto-based privacy-first location identity company that uses passive behavioral signals - where your phone goes, how it moves, what Wi-Fi networks it trusts - to verify users without passwords or biometric friction. Before Incognia, Ferraz co-founded In Loco Media in 2011 at the Federal University of Pernambuco in Brazil, building it into a company that mapped 6 million indoor venues and captured 250 billion location data points monthly, before selling it to Brazilian retail giant Magazine Luiza in 2020. With Incognia, he pivoted that location intelligence from advertising into fraud prevention, raising $46.5M total (including a $31M Series B led by Bessemer Venture Partners in 2024), deploying technology on over 200 million smartphones, and pioneering what he calls zero-factor authentication - security that works without the user doing anything at all.
