How we can work together

  • Circle of Friends: The Stoop Series

    In the Stoop Series, I sit down on my actual stoop and chat with some of the coolest industry leaders, founders, advocates, and changemakers about how to contribute to a more circular world.

    Are you one of the above or a brand looking to sponsor? Let’s chat on the stoop!

    Partner with Circle of Friends to co-host an event that aligns with your brand’s mission. Whether it’s a panel discussion, dinner, investor gathering, or collaborative experience, we’ll create a thoughtful event that brings the right people into the room—curious, values-aligned, and ready to connect, while amplifying your brand’s role in sustainability and circularity.

  • Moderating & Thought Leadership
