Very little has been written about Travis Kalanick’s (Uber’s ex CEO) new company: CloudKitchens. I considered joining his new company when he left Uber, but I wasn’t ready for another startup. It is however an interesting company, likely already valued at $15B-$30B 🧵

Aldi introduced an Amazon-like store in The Netherlands. You can grab your groceries and walk out. Cameras register what you take & auto-charge your creditcard. Zero friction. Except in a country where ppl don’t have creditcards & your app sucks 🤦🏻‍♂️
