Leadership Circles
A platform for women to come together, share experiences and learn from each other. Our circles build leadership capability and personal growth, with valuable insight and practical advice.
About us
Our mission is to inspire, support and encourage women at every stage of their personal and professional journeys.

We believe in the power of community and connection. Through leadership and personal development, we help women reach their fullest potential.
Founded in 2016 by Aduke Onafowokan as The Sister Sister Network, we have grown into Horizon Collective: a community that shows up in different places, bringing the same spirit of inspiration, support and encouragement wherever we go.
Whether you are just beginning or ready for your next big step, we are here, making a difference one connection at a time.

A welcome from our founder
In 2016 I started The Sister Sister Network with a simple belief: when women come together, share honestly and back one another, remarkable things happen. Since then, thousands of women have joined us at Leadership Circles, Arise Summits and online gatherings across the UK.
Horizon Collective is the next chapter of that story. Our new name reflects what we have always been about: helping women see that there is always more ahead, and that they never have to get there alone.
Wherever you are in your journey, you are welcome here. I hope to meet you at a gathering soon.
