My personal belief is that there aren't huge medtech companies because the people founding medtech companies don't know the market - they are coming at it from the perspective of being in tech, or being successful in other arenas, think something is going to be a great idea, and then the wheels fall off because they misread the actual market for their product (ie it doesn't exist, their product isn't useful) or the product they built is fit for purpose but not fit for function.<p>To cite an example from the article, I can think of almost no reason why it would be a net improvement to the world if people were able to have their own personal breast ultrasound machine to monitor breast health.<p>Of course I have significant biases that influence me here, being both a doctor and having a tech startup, I think I'm solving problems no-one else can.<p>One group I think are going to do outstandingly well is Shift Labs. Great idea, and if they have solved the problem with their iv monitors properly then there should be excellent take up
