Endurance International Group

Breaking New Ground


Transformed Endurance into a leader in the shared web hosting market through the acquisition and integration of 17 add-on acquisitions.


Headquartered in Burlington, Massachusetts, Endurance International Group began as an ad-supported web hosting service.  In 2003, the company evolved its technology platform to become a full-service, subscription-based web hosting platform for small and medium-sized businesses, with a unique capability to operate multiple brands seamlessly on a single platform.


While Endurance had an established and reliable platform for web hosting across multiple brands, there was a clear opportunity for the company to leverage its robust technology as an acquisition engine to consolidate an extremely fragmented industry. To achieve its goals, the company needed to further invest in its technology and fuel growth.  To do so, management sought a private equity team that shared its vision and would work with them to help formulate and execute the best possible plan.

Audax Private Equity acquired Endurance in May 2003 and partnered with management to leverage the company’s technology to consolidate the shared web hosting industry.  Together, Audax and Endurance sourced and integrated 17 add-on acquisitions and established the company as an industry pioneer and leader.

The Audax Difference

Audax Private Equity was a terrific match for Endurance because of its ability to work collaboratively with management to source and execute strategic add-on acquisitions. The 17 add-ons significantly increased value, further building the foundation for ongoing organic growth of the business.

Endurance is now the largest provider of subscription-based, shared web hosting services in the world. Endurance provides services to in excess of 3 million unique hosting customers and manages over 12 million domains.

Working with Audax Private Equity has been a rewarding experience. The team’s expertise in creating lasting value for middle market companies through add-on acquisitions was an integral part of our success, and we continue to build on the momentum.”
