About Katie Fellenz
Katie Fellenz on Scooter

I'm an Entrepreneurial Marketing Executive, Impact Investor & Environmentalist who leads with intention and challenges others to “think differently” in pursuit of their highest potential.

My superpower is identifying potential in individuals and organizations, and crafting organic strategies to help them achieve hyper-growth.

As a synergistic leader, I possess a natural aptitude for inspiring & bringing others together in pursuit of a common goal.

I value authenticity, and use my skills to support mission-led organizations with the overall goal of making a positive and measurable social and environmental impact, alongside financial return.

I strive to “do good” for others - working to enrich and improve the world around me, and do whatever I can to have a positive, intentional impact.

My passion is helping female founders solve big problems with sustainable solutions.
