NEW YORK, NY - October 9, 2018 – Today MongoDB, Inc. (Nasdaq: MDB), the leading modern, general purpose database platform, announced it has entered into a definitive agreement to acquire mLab, a San Francisco-based cloud database service. The acquisition is expected to close in the fourth quarter of MongoDB’s fiscal year ending Jan. 31, 2019, subject to the satisfaction of customary closing conditions. MongoDB’s acquisition of mLab will help deepen its relationships with developer-centric startup communities, a segment with which mLab has been very successful. mLab currently has approximately one million hosted databases on its platform across both free and paid tiers.

“MongoDB represents a dramatic sea change in how application developers work with data,” said Will Shulman, CEO, mLab. “There is a trend towards building software systems via microservices and deploying those systems in the cloud. As this trend continues, we anticipate it will open enormous market opportunities for global cloud databases, and MongoDB will be well positioned to power these types of software systems in ways that other database technologies cannot. We are very excited to come together with MongoDB to modernize the way companies store and manage their most valuable asset -- their data.”

MongoDB Atlas delivers the world’s leading modern, general purpose database as an independent, global cloud service. Proven operational and security practices are built in, automating complex and time-consuming administration tasks such as infrastructure provisioning and database setup while ensuring high availability and performance, global data distribution, and consistent backups. Atlas enables users to deploy, manage, and scale MongoDB on Amazon Web Services, Microsoft Azure, and Google Cloud Platform in a few clicks or API calls.

“Atlas has seen tremendous momentum in its first two years since launch, growing over 400 percent year over year in the second quarter of this year. This reflects the popularity of MongoDB in the public cloud and the desire by many customers to consume MongoDB as a service,” said Dev Ittycheria, President & CEO, MongoDB. “The mLab acquisition will give us the ability to scale Atlas even faster. mLab has been providing a compelling service to their customers for seven years and we are delighted to bring this talented team into the MongoDB family.”
