Constant Contact and its parent company, Endurance International Group Holdings Inc., are shuttering their two-year-old startup accelerator SMB InnoLoft, according to Andy Miller, the Constant Contact executive in charge of the program.

But don’t expect the SMB InnoLoft, short for Small Business Innovation Loft, to disappear completely.

Rather, the accelerator will be “spun out’’ into a new, independent operation called, simply, InnoLoft, to be run by Miller.

Miller will serve as InnoLoft’s chief executive, while Laura Northridge, director of the four-month accelerator program, will become InnoLoft’s chief operating officer.

Both will eventually leave their jobs at Constant Contact to focus on the new accelerator full time, Miller said.

Their operation will vacate the 30,000-square-foot space inside Constant Contact’s Waltham headquarters after July 1, when its current batch of startups completes their residency, Miller said.

Miller said InnoLab’s new location has yet to be determined. He said plans are in the “very early stages’’ and that he’s focusing his energy on the five startups whose residency ends in July.

“We will start to figure out what the next chapter looks like,’’ Miller said.

The online marketing company Constant Contact opened the SMB InnoLoft in 2014. Startups got four months of rent-free office space, as well as mentors and the ability to tap the company’s network.

In February, Burlington-based Endurance International closed a deal to buy the publicly-held company for $1.1 billion. Two hundred Constant Contact jobs were cut days later to get rid of what Endurance’s chief operating officer Ron LaSalvia called employee “overlap.’’

In its next iteration, Miller said, InnoLoft will provide its resident startups with resources similar to what they’re getting now. He said they’ll look for corporate sponsors to fill the mentorship and funding gap left by Constant Contact and Endurance International.

In an e-mailed statement, Constant Contact general manager Harpreet Grewal harkened back to the company’s early days — long before its IPO in 2007 — when the then-small startup worked out of a Brookline attic. Despite its growth, Grewal wrote, the company “never lost that startup drive and commitment to innovation.’’

Endurance International, which provides cloud-based tools for small businesses, reported its highest-ever quarterly revenues Tuesday, $253 million, up from $178.7 million for the same period last year.
