About Us

What makes Uncle unique ?

What sets Uncle Sustainability apart is our deep-rooted commitment to environmental stewardship, driven by the belief that integrating sustainability into business strategies reduces climate & transition risks, and ensures long-term success.

Inspired by founder Aude Grasset, we offer a holistic approach combining personalised consulting and comprehensive training.

Our services are further enhanced by Nick Horswell's business consultancy, covering pre-start-up planning, startup survival, growth, and support for selling, merging, diversifying, succession management, liquidating or exiting.
