Trellix software lets users construct web pages without knowing HTML, making it popular among providers seeking to sell web sites to small business customers. Some private-label customers host Trellix-powered sites on their own server infrastructure, while others outsource the hosting to Interland, according to Klein.

Lycos uses Trellix Web Express on its Tripod hosting service, while other companies using service include Dotster, Tucows, iVillage, PeoplePC and McGraw-Hill.

Trellix founder and Interland CTO Dan Bricklin resigned his position in February, but called Interland’s decision weeks later to shut the Concord office “a sad surprise.” Klein said the cuts represented a streamlining of the Trellix operation, which had grown to include more than 100 staffers company-wide, and noted that several members of the original development team will continue with Interland. “When we bought Trellix, what we wanted was the software and expertise of key people who knew the product,” said Klein, who added support for Trellix is provided through Interland’s Atlanta staff.

Large Trellix customers seem unfazed by the recent confusion. “Interland says they will continue to support the product, so we will continue to use it,” said Earthlink spokesman Dave Blumenthal.
