The deal, which closed last Friday, brings together more than 600,000 Web sites. Both companies will continue to operate as separate entities, while collaborating to capitalize on their strengths to deliver quality hosting, Web site services and support, says the company.

“While IPOWER and Endurance have each been successful on their own, it has been clear to both companies that continued success requires more scale and resources than either company could have alone,” says Thomas Gorny, IPOWER CEO. “The ability of the merged companies to grow simultaneously through organic customer adds and acquisitions, along with new product offerings to our combined customer base, will make for an incredible force in the industry.”

The new organization will use IPOWER’s marketing resources, Endurance’s operational expertise and the powerful backend capabilities of the combined organization positions to support its large customer base with exceptional hosting and new products and services, says the company.

“IPOWER and Endurance are both known for innovation,” says Steve Sydness, CEO of Endurance International. “Together, we can lead the industry with best-in-class products and technologies that enable us to respond quickly to our dynamic industry-and address our customers’ growing expectations.”

Financial details of the sale were not disclosed, but the companies say Endurance will maintain the PowWeb brand, as well as its popular online forums.

“We’re very excited to work with an online community as dynamic and engaging as PowWeb’s,” says Steve Sydness, CEO of Endurance. “Listening and responding to customer feedback is a hallmark of Endurance. The PowWeb forums will provide a great vehicle for staying close to our customers.”

PowWeb CEO Andrew Te says the company is about to begin the process of migrating customer Web sites and email to a new hosting platform that employs the company’s proprietary load-balanced hosting technology. He says the new platform will support all its customer sites from a single massively shared hosting pool, which will provide greater redundancy.

“While its ownership has changed, PowWeb’s commitment to providing high-quality, rock-solid hosting solutions is stronger than ever,” says Te.
