November 2024'S Top 10 European Tech Deals You Need To Know About

According to the Tech.eu database, European tech companies raised €5.2 billion over the course of November 2024. This figure is 30 per cent higher than the previous month when European tech companies raised €4 billion. Compared to November 2023, however, the amount has decreased by around 8 per cent, as European tech companies raised €5.6 billion that month. RJ Schuurs, Partner at Antler, commented on the November numbers within the European tech investment landscape in our November Tech.eu Pulse, a compact version of the monthly report:We have seen countless examples of startups that focus on capital efficiency and start with relatively small Pre-Seed and Seed rounds go on to raise significant amounts of funding further down the line. This long tail of early-stage startups may not attract the same kind of headlines, but they are the engine room of the European tech ecosystem and represent a critical mass of venture-backed, fast-growth startups whose success will define the next ten years
