Season 4: Episode 4 - Sarah Fliessbach - CEO and Founder @ Shareclub

September 04, 2025 • Richa Pathak • Season 4 • Episode 4

Continuing our series of amazing women founders of cleantech companies in Ireland, we are proud to present a brand new episode featuring the story of Sarah Fliessbach from Shareclub.

Having moved across to Ireland from her home country Germany, Sarah saw how Ireland is one of the largest consuming countries of single-use plastic.. And she immediately went about fixing the problem by setting up her own venture - Shareclub!

Shareclub is an App-enabled ecosystem of reusable containers, starting with tackling the omni-present take-away coffee cup. They are scaling through enterprise customers and large events alike - they recently helped the Dublin Coffee Festival completely avoid the use of single use cups!

Tune in to hear her story and ambition and don't forget to leave your feedback.
