As a self funded founder I feel you that the stories about what we do are unheralded and we have different challenges than other businesses (good ones that force us to find the right answer quicker).
There are businesses that are not self fundable, though and will take massive amounts of investment to make happen. Uber is one since they need to get critical mass of drivers/riders in many cities to take over. uBeam is also one of those companies, as a whole lot of R&D has to be done to take it to market. They have a thesis and if correct will have a big impact and can only be done with some real investment (can you imagine self-funding this??). This seems like the perfect thing to invest in.
Its super easy to poke holes in other peoples business but we are also not working with all the information. Let her work!
