In this episode, José, founder of Segura and Blue Earth B100 winner, shares how his team is transforming water quality testing, from slow, expensive lab processes to real-time, on-site results.

Drawing on years of experience in water chemistry and global consulting, José breaks down the scale of the problem utilities face, why existing systems no longer work in a changing climate, and how Segura is repurposing medical-grade technology to deliver faster, cheaper, and more scalable testing.

We dive into early pilots with major global organisations, the path to certification, and what it takes to build a deep tech company at the intersection of infrastructure, climate, and data.
