About
Social platforms are the critical communication infrastructure in our lives, communities, and democracies.
From how we communicate with our loved ones and connect with our neighbourhoods to exchanging ideas and sharing our thoughts.
More than 20 years ago, Europe was buzzing. People were coming together from across the continent to build our social digital future — to make the internet social rather than transactional through innovation. A new type of platform emerged, pioneered by entrepreneurs also in European countries: social platforms. Creating new design patterns, new behaviours, new cultures, new concepts — the world we live in today.
Today, social platforms are how we connect with new people, how we keep our families updated, how we socialise, how we organise, how we share, how we build relationships, how we find love, and how we exchange goods. Digital social groups are the fabric of our relationships, our neighbourhoods, our cities, our sports clubs, our communities of interest — our societies.
They are critical infrastructure and an important industry that should employ hundreds of thousands of people in Europe. But in the 2000s, Europe lost the battle to a few centralised foreign platforms. We lost our social platform industry and our capacity to innovate.
Luckily, new seeds of social platforms are popping up all over Europe. It's time to support and grow this new generation of builders.
We've talked and reflected a lot in Europe; now it's time to rebuild. To regain our sovereignty. To rebuild an industry. To lead by innovating social platforms. To create a diversity of platforms. To build on every type of model — from start-up to NGO and open source. To create solutions instead of pointing fingers at the old, broken ones. To bring all forces in Europe together — the generations that pioneered, the new builders, the thinkers, the investors, the experienced entrepreneurs — to make it happen.
On 15 December 2026, Rebuild will host the last gathering in Paris, open-sourcing all frameworks, tools and resources back to the industry.
Rebuild is an NGO, registered in Denmark, supported and funded by European entrepreneurs and the Danish Industry Foundation.
Founded by Thomas Madsen-Mygdal, patroned by Margrethe Vestager.
