I created a public equities investment fund in 2009 that has out performed the market ever single year since 2009, except for one. Its positions have remained quite steady over the years and it has outperformed the S&P 500 by more than 2.5x. You can see the performance and details here.
I also invest in, advise and sit on the board of early stage startups in healthcare, education and greentech companies.
Some of my favorite private investments were/are SelectMinds, Chart.io, PresenceLearning, DoktorSitesi, Humantelligence, Atolye Istanbul and Complete Solar.
