A community for women since 2016

There is always more on the horizon.

Horizon Collective is a community for women who believe there is always more to discover: a place to connect, learn new things, encounter new ideas and explore what might be possible next.

Who we are

When women come together, horizons expand.

Formerly The Sister Sister Network.

We support women to connect, build new skills and explore new horizons. We are driven by a simple idea: show up, impact lives and build community.

Our purpose is to be a guiding light for women at different stages of their lives, so that no one feels alone or believes their ambitions are out of reach. Whether you are just starting out or preparing for your next big step, there is a place for you here.

Leadership Circles

Intimate gatherings where women share experience and learn from one another. Each circle builds leadership skills and personal growth through practical, honest conversation, in person across the UK and online.
