What our participants say
Patrick Nathen
Co-founder, Lilium
The kind of momentum, the ideas and the inspiration that you get here is very unique compared to any other founder summits that I have experienced so far.
Kami Krista
Co-founder, Elio
If I could only go to one conference every year, Sigma Squared Society’s global summit would be the one - hands down and by many miles. It’s indescribable magic where you build really deep professional and personal connections.
Sian Sutherland
Co-founder, A Plastic Planet
The Sigma Squared Summit brings together driven founders who are fearless and fully realise the imperative to reimagine and reinvent the world of business where positive impact is a more important metric than only profit.
Vaitea Cowan
Co-founder, Enapter
The variety of participants in the summit creates an open book of knowledge for fruitful conversations. It is a unique occasion to challenge our beliefs and co-create the roadmap for a better future.
