Boston ad technology firm ChoiceStream has raised $7.5 million in new funding, its second round since a major pivot in 2011.

Since then the company has focused on offering technology that lets advertisers bid automatically on having digital ads targeted to customers, in what is known as “programmatic” advertising. (ChoiceStream’s initial focus was on product recommendation software.)

ChoiceStream customers include Zappos, Dunkin’ Donuts, and AAA.

The new funding was led by Fred Alger Management of New York. ChoiceStream had raised $8.7 million in 2011 from investors including Sage Hill Partners and Sutter Hill Ventures.

Thermalin raises $5.9 million

Thermalin Diabetes, a developer of new forms of insulin with an office in Newton, has raised $5.9 million in new funding for its development work.

The Series B round comes from private investors, who were not named.

Thermalin, which also has an office in Cleveland, is developing Fluorolog, which aims to be the first meal-time insulin that works for diabetes patients who need high doses of insulin to control their blood sugar. The insulin is highly concentrated and rapid acting (with an onset of about 30 minutes).
