Led by Jenny Abramson and launched in 2017, Rethink Impact is one of the newer funds to invest solely in women. But with $112 million in its coffers, it also may be the largest. (Intel Capital's Diversity Fund also invests in people of color and other underrepresented groups.) The fund's investors include Sheila Johnson, co-founder of Black Entertainment Television, and Sachiko Kuno, who has co-founded two drug companies. Abramson and her colleagues are looking for women-led tech companies that also intend to have a significant and positive social impact. Rethink typically makes an investment at the Series A stage. Its portfolio companies include Seedling, Neurotrack, and Werk.
