Hyperbeam
Hyperbeam is a developer API for embedding cloud-hosted virtual computers and multiplayer web browsers directly inside any web, mobile, VR, or desktop app. Built on streamed Chromium instances delivered over WebRTC, it lets many people view and control the same live browser session at once - powering watch parties, co-browsing, remote learning, virtual offices, and increasingly the browser layer for AI agents. Founded by three University of Waterloo engineers, it went through Y Combinator's Winter 2022 batch.
Thomas Cottereau
Thomas Cottereau is the CEO and co-founder of SightCall, a San Francisco-based platform for AR-powered live visual assistance used by enterprises in insurance, manufacturing, healthcare and utilities. A telecom engineer who helped build early internet infrastructure at UUNET and MCI WorldCom, he started SightCall in 2008 in a friend's basement and spent five years turning a video prototype into an enterprise SaaS platform, later moving his family to the Bay Area and winning HP as an early flagship customer. Under his leadership SightCall raised roughly $58 million and grew into a global company serving customers across every continent.
LiveKit
LiveKit is an open-source platform and global edge network for building real-time voice, video, and physical AI applications.

Its technology powers ChatGPT's Advanced Voice Mode and is used by developers at OpenAI, xAI, Salesforce, Tesla, and Spotify, collectively facilitating billions of real-time calls each year.
SightCall
SightCall is a San Francisco- and Paris-based enterprise software company that turns a customer's or technician's smartphone camera into a live support channel. Its cloud platform blends real-time WebRTC video, augmented-reality annotations, and multimodal generative AI so that a remote expert - or increasingly an AI agent - can see what someone in the field sees, guide them through a fix, and automatically document the session. Used by brands like Ford, Allianz, GE HealthCare, Deutsche Telekom and Lavazza, SightCall targets field service, insurance claims, customer service and healthcare, aiming to resolve problems on the first contact and cut unnecessary truck rolls.
ProjectX
ProjectX is a San Francisco-based, Y Combinator-backed startup building Infinity (InfinityOS) - a cloud-native, distributed operating system where every app runs on its own independent compute and GPU inside a single browser tab. Designed for the multi-agent, GPU-native era, it lets humans and AI agents run Blender, Unreal, Isaac Sim, DaVinci, and VS Code side-by-side in one shared workspace.
