About us

Borski fund was founded based on the conviction that the investment diversity gap is real and much larger than is often thought, however that there are also ways to help close it. There is a wide array of research that indicates female entrepreneurs often deliver better results than their male counterparts, whereas >90% of VC money goes to all-male management start-ups. We believe that improving access to financing for female entrepreneurs that are looking to contribute to a better world is one of the key ways of addressing the investment diversity gap.

The fund is named after Johanna Borski. Johanna Borski was a female investor and role model to many female entrepreneurs. Johanna Borski made a fortune by investing early on in buying almost half the shares issued in “De Nederlandsche Bank” in 1814. With the profits made, she later went on to rescue the “Nederlandsche Handel-Maatschappij” from bankruptcy in 1840. The way Borski used funds to do good for the world in a time when investing was (even far more than today) a male-dominated business, was a source of inspiration when establishing our fund.


An investment from Borski goes beyond just providing money. Our strength lies in combining market knowledge, an expansive network, a strong entrepreneurial track record and investment experience. This means that Borski stays involved actively after providing financing. How do we do all of this? Meet our team below:

“When we look through a gender lens, disparities between men and women’s ability to access capital become quickly apparent. Across all industries—from retailers, to filmmakers, to high-tech entrepreneurs—women have historically had trouble gaining access to investment capital, despite evidence that women-led companies may deliver higher and more consistent returns.”
