Tether
Tether is a Barcelona-based climate-tech startup whose AI platform predicts and coordinates the charging behaviour of millions of private electric vehicles, aggregating that flexibility into a virtual power plant that bids into grid balancing markets and enables smart charging and V2G. It sells via a SaaS/revenue-share model to EV OEMs and charge point operators (partners cited include Audi and Zeekr), sharing income earned from the energy markets. Founded in 2023 at Norrsken Barcelona (originally named Luma) and a Techstars '23 company, it raised a ~€1.3-1.5M pre-seed in June 2025.
