If you build an innovation hub, the investors will come.

That seems to be the idea that Mayor Thomas Menino had in mind when he began to build out Boston’s Innovation District, which has added 4,000 jobs over the past four years. Now that startups have taken up residence in the Seaport, the area’s investors are migrating back to Boston proper, too.

Venture firm Polaris Partners finalized a deal today to officially make the move from Waltham, Mass.’s office park to Boston’s budding Innovation District, reports the Boston Globe.

Polaris will plant roots in the Fan Pier development and take up 16,000 square-feet of space at One Marina Park Drive–the former home of local accelerator MassChallenge–according to The Fallon Company, the building’s landlord. The venture firm will most likely move into its new digs near year, but won’t officially open its new global headquarters in Fan Pier until 2016. 

“Polaris will have front row access to the entrepreneurs who are working, thriving, and developing new ventures in the Innovation District,” said Menino in a press release.

Yet another Waltham-based venture firm, Battery Ventures, which has invested in Groupon, Angie’s List, and Akamai, also announced its plans to move to One Marina Park Drive  in December 2012.

In addition to its Waltham space, Polaris also holds offices in San Francisco and Dublin, Ireland. Polaris is best known for its investments in technology and life sciences. In the past, the VC firm has backed companies Logentries, which just raised $10 million in Series A, LogMeIn and Localytics, among others.
