Our Mission

Our goal is to make the world a better, more sustainable, equal, and equitable place by breaking barriers in traditionally male-dominated spaces and providing financing, mentoring, and advisory support to women to become leaders and decision-makers in their fields. We see the gender financing and gender data gaps as interlinked challenges. Together, we invest, learn, grow, and succeed.

Who We Are

At Investress, our international team of experts has a deep commitment to equality and sustainability. Comprising seasoned professionals from diverse sectors, we bring unparalleled expertise, passion, and insight to our portfolio of investments and initiatives.

Combining academic rigor with practical experience, she has managed diverse teams and projects across different contexts and sectors.
