Index Ventures led the deal with participation from Institutional Venture Partners and Atomico. Founded in 2011, SuperCell is currently the highest-grossing iOS game developer with “Clash of Clans” and “Hay Day” now bringing in $2.5 million of revenue daily.

Enlighted raised $20 million in Series C funding led by Rockport Capital for its lighting-controls technology, as it operates in a quickly changing market where the price for lighting emitting diodes is declining. The company makes sensors and software that is installed in commercial spaces and that helps decide when to dim lights. A newer application of the technology would also allow the sensors to measure temperature and occupancy, and control not just lighting but also air conditioning.
