Nansen CEO: In recent years, as an angel investor, I have participated in 58 projects, 19 of which have gone to zero.
Nansen CEO Alex Svanevik, in a discussion with Zen Academy founder Zeneca about their angel investment track records, stated that in recent years, he has invested in a total of 58 projects as an angel investor, of which 8 have been very successful, 10 have entered the next round but are still awaiting results, 14 have not yet entered the next round, 7 have been partially refunded (due to acquisition or losses), and 19 have gone to zero.
Zeneca's track record is that he has invested in 68 projects, of which 3 have been very successful, 4 have been slightly successful, 15 have had small losses, 8 have had large losses, 10 have gone to zero, and 22 are still awaiting results (but without much hope).
