21 European Cybersecurity startups at Slush 2021
After a year’s hiatus, Slush will host an in-person startup event in Helsinki on December 1–2, 2021. This year, 3,200 startup founders and operators and 1,500 investors are expected to join Slush, with 8,000 attendees in total.
What started as a gathering of 300 local founders in 2008 has become a community of true global magnitude. Yet, the mission of Slush remains the same: to create and help the next generation of groundbreaking entrepreneurs.
Slush is a student-driven, not-for-profit movement originally founded to change attitudes toward entrepreneurship.
Such movement has enabled it to scale to one of Europe’s most significant tech events.

The entire city gets involved, and thousands of university students volunteer for the good of the city and the ecosystem. The collegiate nature of the Slush experience has reflected how Helsinki has grabbed the opportunities of tech with both hands.
Slush has even seen ex-employees go on to found big startups. For example, food delivery startup Wolt, co-founded by Miki Kuusi, an early C.E.O. of Slush, raised €762 million since 2014 and was acquired by DoorDash on Nov 09, 2021 for $8B. Other big startup companies from Helsinki’s ecosystem include Smartly, ZenRobotics and Blok.
Slush’s ability to attract V.C.s to a Northern European country in the middle of winter was impressive. First, the city rolled out the red carpet. That meant inbound V.C. exploded. Crunchbase lists 57 venture funds of various guises in Helsinki.
Helsinki startup ecosystem has showed great resilience during the pandemic. Venture capital flow into Helsinki-based startups keeps growing and the message is clear – there is quality in the ecosystem.
said Marja-Leena Rinkineva, Director of Economic Development, City of Helsinki
Startup Genome marks out Helsinki as one of the top global ecosystems. For 2021, it valued the Helsinki startup ecosystem at $6.6 billion, with total early-stage funding of $549 million, a little bit higher than the global average for emerging ecosystems.
For many reasons, startups want to come to Slush and present their solutions to find investments, hire talents and establish face-to-face connections.
