TechBreakfast: Four startups pitch at TechBreakfast, bright and early this Tuesday. Linute is an iPhone app for “last-minute” activities; Wizio is an apartment-hunting comparison tool; GemShelf is knowledge management; Stack.ai is personal CRM. Break out.

Techstars Boston Demo Day is Tuesday night. The public event is separate this year from the day in which investors actually invest money in Techstars startups, which is today. Shifting the money to private takes some of the drama out of the thing, but Ty Danco says it was necessary. Go public.

Boston Data Mining has a sold-out Scikit workshop with Lukas Biewald, founder and CEO of CrowdFlower. Next time.

Social Data and Analytics in Healthcare: DataXu hosts a meet-up that mashes up healthtech and adtech. Boston Children’s Hospital research associate Jared Hawkins, Epidemico CTO Clark Freifeld (also Children’s) and MIT researcher Morgan Frank will speak. Well-liked.
