Have you heard of European Pitch Network? Well, if not, you better check their website: https://www.euro-pitch.eu/
It´s per se an early stage startup (actually in the proof of concept-stage).
The idea is to build a virtual Silicon Valley for Europe, in fact an appbased social media Plattform for European StartUps and Investors.
As a startup/entrepreneur you will have the opportunity to present/pitch your idea online within the app, get in contact with startups from all over Europe, network, interact, search for advice/cofounder/partners…
On the other hand side investors, corporates and VCs will have the opportunity to scan the European market, contact interesting startups…
From Israel to Iceland and from Portugal to Россия (Russia) but with HQ in Frankfurt.
By the way, if you like the project and got some hints into possible synergies, they are indeed searching for partners and also maybe Co-founders with a tech-background.
