About the Author

Net Interest is written by me, Marc Rubinstein. I spent ten years as a partner of an award-winning hedge fund. Before that I was a top-rated analyst at an investment bank. When I’m not writing Net Interest, I consult with corporates and investment firms and I’m also an active angel investor in fintech. You can find out more about me via LinkedIn or Twitter.
