The Estonian delivery startup Starship uses tiny self-driving robots. I wonder if those can be made cost-efficient.
They launched around me last month at around 50 cents per delivery and I used it quite a bit. Now that the introductory period is over and the fee is 1.50, I just get off my ass and walk.
The funny thing is if they launched with $2.50 delivery and cut the price to $1.50, I think many people would feel differently about the current price.
Also one of the plays is they collect data on your purchase habits and can stock better /suggest higher margin alternatives.
