Today’s funding announcements include new ways to invest in stocks, buy cheap event tickets and build sustainable companies:

Kapitall gets $7.3M for easy investing app: Stereo Scope, parent company of app developer Kapitall, has raised $7.3M in new cash and has converted more than $5.5M of previously issued promissory notes in a first round of funding.

Online ticketing site ScoreBig brings in additional funding: The Los Angeles-based startup has now raised a total of $8.5M in a round led by Bain Capital Ventures for its members-only online ticketing service.

The site launched in beta this week, and in contrast to other popular ticketing sites, buyers don’t know the exact location of their seats until after the tickets are purchased.
