About Net Interest

Net Interest is a weekly newsletter of insight and analysis from the world of finance. Enjoyed by senior executives and smart investors around the world, it casts light on this important sector in an easy-to-read style.

Written by a former analyst and hedge fund manager, Net Interest distils 25 years of experience in the financial sector into a weekly email. Each post explores a theme currently trending in the sector. And because there’s a financial company lurking inside almost every company, there’s always something to talk about.

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.
