MongoDB Co-Founder Sells Shares Worth 4 Billion Won, Still Holds Significant Stake

Dwight A. Merriman, co-founder and director of MongoDB, Inc. (NASDAQ: MDB), sold several thousand of his personally held shares and shares held in a trust for his children on April 14 and 16 under a pre-established Rule 10b5-1 trading plan. The transactions generated roughly $3 million in proceeds—approximately KRW 4 billion—while Merriman still retains a substantial stake of several million shares through his personal holdings, trusts, and charitable foundation.

Recently, MongoDB announced it will report its fiscal 2027 first-quarter results after the U.S. market close on May 28, marking its first earnings release for the quarter ended April 30.

Founded in New York in 2007 by Dwight Merriman, Kevin P. Ryan, and Eliot Horowitz, MongoDB is a database software company specializing in unstructured data and is now a global software firm listed on NASDAQ. Merriman—an internet entrepreneur who also co-founded DoubleClick and Business Insider—has played a pivotal role since MongoDB’s inception as both a co-founder and board member.
