I geolocated every funded neurotech company I could find (564 of them) and every investor too (107)
I run a neurotech recruitment, market data and media business and finally did something I had been putting off, placing every funded company by headquarters and then doing the same for the investors. 564 companies, 107 investors I could confirm. 330 of the companies are American, and all of Europe combined is 165. The investor side is even more concentrated, 81 of the 107 are US-based. What struck me is that US investors clearly fund a lot of the non-US companies too, so the geographic gap in where the money comes from is even wider than where the companies are. Happy to talk through the method or the gaps in the comments. Full write-up with the charts and the investor list is linked below.
