Connecting startups, capital and opportunities

Upstream is where early-stage startups find capital and opportunities. Founders and investors are invited to join us to spark growth through funding opportunities, strategic partnerships and peer-learning. Upstream brings in some special focus on three industry tracks being, Port & Maritime, Health & Wellbeing, and Climate & Energy, while continuing to welcome innovations from all sectors. Whether you’re raising, investing, or looking to connect with peers, this community-driven festival is your gateway to meaningful connections.

Climate & Energy, Health & Wellbeing, Port & Maritime

While the opportunity to connect with peers remains relevant for founders across all industries, Upstream puts a special focus on innovation happening in the the fields of Climate & Energy, Health & Wellbeing and Port & Maritime. These three tracks are not just themes – they are the core of the festival. Together with our partners, these tracks will be shaped into relevant content, bringing in specialized investors who truly understand these domains, and support the most innovative founders who are building solutions that move the needle.
