Sigma Squared Summit

Get a glimpse into the future by meeting those who are building it.

What you need to know

The Sigma Squared Summit is a global invite-only event that unites the most ambitious young founders, serial entrepreneurs, executives and investors to initiate change and push the boundaries of what is possible.
At our summits, you will get a glimpse into the future by meeting those who are building it while forming long-lasting partnerships and friendships.
This year, we will unite at the Nova SBE close to Lisbon, Portugal.




18-19 November

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.

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.

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.

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.
