From the partners
What we prioritize
We prioritize AI-native founders building on the Industry 4.0 toolbox for our target sectors — both the data producers (sensors, satellites, monitoring) and the data consumers (AI, digital twins, decision software) — focused on displacing legacy incumbents and advancing a future where scalable technology, not consulting studies, enables industry and society to manage hydroclimatic risk more effectively.

What we are bullish on
We are bullish on founders who demonstrate conviction about the future direction of their market and build for where demand is going, not where it is today — anticipating shifts in customer needs, regulation, and technology, and positioning their companies ahead of those changes.
