Wayve is a British autonomous driving company founded in Cambridge in 2017 that trains end-to-end neural networks to drive rather than assembling hand-written rules around high-definition maps. Its AI Driver learns from camera video and can be deployed on standard vehicle sensor sets, which is what lets the company demonstrate driving in cities it has never mapped. Headquartered in London and backed by a one billion dollar SoftBank-led round plus investment from NVIDIA, Microsoft and Uber, it partners with carmakers to ship assisted driving software and is developing fully driverless deployments.

Addepar is an American financial technology company founded in 2009 by early Palantir employees who found that wealthy families and their advisers had no reliable way to see all their assets in one place. Its platform aggregates holdings across custodians, private funds, property and operating businesses, then reports performance and exposure across the whole picture, which conventional portfolio systems built for listed securities cannot do. Headquartered in Mountain View and privately held, it serves registered investment advisers, family offices and private banks tracking trillions of dollars in assets.
