Boston edtech startup accelerator LearnLaunch on Tuesday named six startups to its Winter 2015 session, the third session so far for the program.

Through the four-month program, the startups are granted mentorship, workspace at the LearnLaunch office in Back Bay and $18,000 in seed funding. In turn, LearnLaunch takes a six percent equity stake in each of the companies.

The accelerator culminates with Demo Day pitches on June 3.

LearnLaunch Accelerator has invested in 13 companies previously, and graduated its most recent class last May.
