According to Crunchbase, Massdrop raised ~92 MM through their series C, and then another ~40 MM in debt over the last couple years.
There is no way that MassDrop was ever going to justify that kind of capital investment. VC is such an inefficient and frankly delusional form of capital deployment at this point -- they have no idea what they're doing. It ironically looks a lot like central planning, where the VCs themselves invest with the intention of picking the winners and losers themselves.
This company should've bootstrapped and remained small-and-manageable. Not every business, not even most businesses, should raise money with the intention of becoming a "unicorn," it is nonsensical and this model has a lot of deleterious effects for our society, namely and most obviously enshittification when the outcome doesn't justify the investment.
