The Israeli Public Service Venture Fund is a non-profit organization, established by leading Israeli venture capital funds to involve the high-tech sector in supporting charitable activities.

The model is simple: early-stage companies offer Tmura a warrant, convertible (at exit) into a small portion of their equity. If the company succeeds, Tmura sells its shares and donates the proceeds to charities in Israel; the focus is on education and youth-related activities, and the companies can indicate which organizations they want to support.

Carmel, as well as several other leading venture capital funds, support Tmura's activities and encourage portfolio companies to make an equity donation to Tmura.
