Glacier builds AI-powered robots that sort recyclables inside Material Recovery Facilities (MRFs). Their compact, conveyor-mounted robots use computer vision trained on billions of recycling images to identify and pick more than 70 material categories, while also generating real-time data on what flows through the waste stream - data that brands and recyclers use to prove and improve circularity.
Rebecca Hu-Thrams is the co-founder and CEO of Glacier, a San Francisco-based company building AI-powered robotic arms that sort recyclables in material recovery facilities. Raised by Chinese immigrant parents who instilled a 'reduce, reuse, recycle' ethos, she channeled her Bain consulting background and Thumbtack operating experience into tackling what she calls 'the most demented form of manufacturing on the planet.' Glacier's robots, trained on 3.8 billion images of waste, sort 70+ material categories at 60 picks per minute - preventing roughly 10 million items per robot from reaching landfill annually. Named Fast Company's #1 Most Innovative Company in Robotics & Engineering for 2026, Glacier has raised $33.2 million including a $16M Series A extension in April 2025 backed by Amazon's Climate Pledge Fund and New Enterprise Associates.
Dimension is a San Francisco-based B2B waste management platform (formerly Trash Warrior) that uses software and an AI price quoter, Mirror Mirror, to coordinate hauling, recycling, and hazardous waste removal for enterprise customers like Amazon, Instacart, Home Depot, and the DEA - with the long-term aim of pulling the U.S. recycling rate from 35% to 75%.
Lily Shen is the Founder and CEO of Dimension, a San Francisco-based technology platform transforming waste management with data-driven, full-service solutions. A Princeton and Harvard Kennedy School graduate, she previously held roles at Niantic (Pokemon Go), Opendoor, Deloitte, and the Federal Reserve. Dimension, formerly Trash Warrior, has raised $19.5M in funding and operates in ~300 US cities with a mission to raise the national recycling rate from 35% to 75%.
