Europe’s fastest growing climate tech startups

There’s a lot of talk right now about how resilient the climate tech sector is to macro conditions rocking the broader tech market.

Although we have seen layoffs at some major climate tech companies, such as electric truck maker Arrival, the industry has not seen the collective redundancies other sectors have felt it – and climate companies continue to grow.

Sifted analyzed the 10 fastest growing of all, by headcount, based on data from business room.

To prevent the results from being skewed by extremely small teams that recruit a lot, we only look for companies that have raised more than 50 million euros in total.

Membership growth can give a good indication of the rising stars in the climate tech world and the companies we should be keeping an eye on.
