Cartken Courier

Cartken (founded 2019 by ex-Google 'Bookbot' engineers; CEO Christian Bersch) makes the Cartken Courier (Model C), a six-wheeled sidewalk delivery bot (about 44 pounds and 1.5 cubic feet of payload, 3 to 6 mph), and is the hardware-sale-pivot archetype of the cohort, editorially distinct from Starship and Serve: where they operate their own fleets, Cartken pivoted toward selling vehicles to operator partners. Its partners include Mitsubishi, Uber Eats, and Melco, and its lineup adds a larger industrial Hauler (2025; 660 pounds / 300 kg) and an indoor Runner. It is operator-supervised, not driverless. It has raised about $22.5 million (468 Capital, Magna International, Shell Ventures, Mitsubishi Electric). Cap-flag: the roughly 100 Hauler vehicles cited in the Melco deployment is an aggregator-quoted figure pending direct Cartken or Melco disclosure. As a B2B hardware sale to operator partners, there is no consumer price.
