Hexa × Antasphere Sauna: Founders & Investors
⚠️ Due to very high demand and very limited capacity, all registrations are subject to approval. We’re reviewing each request individually — request your spot below, and we’ll email you if your attendance is confirmed. Don't apply if you're not 100% sure of being able to attend.
Slush week, the Finnish way.
Hexa and Antasphere are bringing founders, operators and investors together for an afternoon of sauna, cold plunges and good conversations, away from the Messukeskus crowd.
Expect people from the Paris and Brussels ecosystems, and anyone building something worth talking about.
🗓 Wednesday 18 November, 14:00–16:00
📍 Outdoor sauna in central Helsinki (address shared on approval)
🩱 Bring a swimsuit and a towel
Spots are limited: registration is approval-based.
