A sustainable investor’s guide: Top 8 GreenTech pearls from Estonia

Invest Estonia picked up eight Estonian GreenTech pearls to keep an eye on as a sustainable investor from last week’s GreenTech Week in Tallinn.

Last week’s GreenTech Week Tallinn served as a platform for showcasing the most innovative ideas in sustainable technology from Europe to America, highlighting Estonia’s commitment to a greener future. The event’s program featured a plethora of groundbreaking green concepts and events, captivating the attention of technology enthusiasts, sustainability-focused investors, and tech companies on a global scale.

From NEXPO Tallinn to the Cleantech Forum, participants seized every opportunity in the event schedule to delve into GreenTech, expand their knowledge, and establish connections with prospective partners in terms of investment, trade, and collaboration.

“The CleanTech Forum Europe united a notable assembly of investors and innovators, all deeply impressed by the diverse array of Estonian green technology firms and their exceptional ideas,” noted Joonas Vänto, Director of Invest Estonia and host of the CleanTech dinner.

Keeping sustainable investors in mind, we have selected the shiniest GreenTech pearls from Estonia’s jewellery box to keep an eye on in the coming years.
