January Ventures is a venture capital firm founded in 2018 by Maren Bannon and Jennifer Keiser Neundorfer, focusing on early-stage B2B technology startups that are digitally transforming traditional industries. The firm is headquartered in Boston and London, and has invested in 60 companies to date. January Ventures is a woman- and Latina-led fund, with 90% of its portfolio companies having a female founder, 32% having a Black or Latina founder, and 42% having an immigrant founder.

The firm aims to back founders based on their differentiated industry expertise, outsized ambition, and demonstrated tenacity, rather than their pedigrees or networks. January Ventures has invested in companies such as Ethena, Kapwing, PlanetFWD, Sonantic, Ntropy, Sorcero, Gable, Oula Health, Kinside, and Elektra Health. In April 2022, the firm announced the close of its $21 million Fund II, with plans to invest in 35 to 40 companies.

Investors in Fund II include Wellington Management, Bank of America, IDEAL Investments, and The Kapor Foundation.
