SumZero is the leading global community for buyside investment professionals. The site has rapidly grown to 3160 elite hedge fund and private equity analysts - almost every brand-name hedge fund and private equity fund is represented in SumZero's user base.

The concept is simple. There are currently 1856 full-length, peer-rated investment write-ups in SumZero's Quick Idea database (covering equities, credit, macro, commodities, and other asset classes). By contributing one idea, a member gains access to the entire database. Furthermore, the member can run proprietary valuation screens where forward projections are buyside numbers, not sell-side. See below for sample ideas from the database.

Additionally, there are thousands of companies in SumZero's database of extensively researched companies, each of which is tied to a specific buyside analyst. An analyst can easily identify a list of other leading buyside analysts who have done work on the company he/she is interested in and contact them to compare notes, deepen each other's understanding, and build one's professional network.

If you would like an invitation to join, please send an email with a few sentences on your background to application@sumzero.com. Though optional, it helps to include an actionable investment write-up and CV in your application.
