MIT Discloses 3 New Managers

MIT has disclosed three new managers for the first time, according to documents recently obtained by OWL. This comes on the heels of two new disclosures that we covered in April. Please reach out if you’re interested in learning more about how to use OWL to find interesting new managers!

Allocator filings are one of several ways to identify promising emerging managers on OWL – users are also able to see new ADV filers, new 13F filers, team change alerts, and our new Recent Launches feed, helping them identify interesting managers before they are discovered by peers.

Based in Louisville, Kentucky, Aristides was founded in 2008 by Claire Brown. Brown did not start her career as an investor, though she did start investing in equities at the age of 11, according to Aristides’ website. She earned a bachelor’s degree in biological sciences from the University of Chicago and her MD from the University of Kentucky College of Medicine before joining the US Air Force medical corps as an active-duty officer.

During medical school she co-founded a commodity trading advisory firm, MarketBeacon, and co-founded the Doctors Without Brokers investment club.

Aristides, named after the first winner of the Kentucky Derby and sharing a name with an ancient Athenian general, runs a book of around 80 long and up to 80 short positions rebalanced on a quarterly basis, according to its website.

According to Brown’s LinkedIn, Aristides runs two “funds-of-one” for a “top university endowment,” which OWL believes to be MIT. As of 6/30/25, MIT disclosed a $47.8 million investment in a vehicle named Louisburg Square, which is a disclosed Aristides fund. Louisburg Square is also name of a Boston-area park with a statue of Aristides the Just, the aforementioned Athenian general.

Aristides also lists a vehicle named Louisburg Square II on its most recent ADV with a value of $41.6 million, which may also be associated with MIT given Brown’s LinkedIn disclosure.

The manager’s AUM has increased steadily since it first disclosed it in 2020:

In Friday’s newsletter, OWL users received profiles on the two other managers new to MIT’s portfolio. Users can also see more details on MIT’s portfolio on OWL, which we have gathered from several obscure public sources.

OWL is an intelligence platform built for allocators, by allocators. Leading endowments, foundations, and family offices use the system to find, monitor, and connect with thousands of fund managers globally. OWL's analytics engine has collected over one billion data points from 65 countries. We make it easy for allocators to find and track information about the managers they care about – not just positions but also performance analytics, people data, business information, and details about the manager investments of other allocators.

Returns represent the return on invested capital of publicly disclosed long positions, as calculated by OWL. Actual returns may vary based on a number of factors, including (but not limited to) undisclosed positions, short exposure, non-equity holdings, cash holdings, and lagged disclosure of positions.
