The problem

Cities lose a third of their treated water to leaks underground, and find them only when a street floods.

The solution

Aqualine fits acoustic sensors to existing hydrants and pinpoints a leak to within two metres, while it is still the size of a pinhole.

Who it's for

Municipal water utilities serving 50,000–2 million people.

Market

Bottom-up: about 105,000 customers like this in Chile and nearby, worth roughly $280 million a year at our prices.

Competition and edge

What people use today

Mostly spreadsheets, phone calls and doing nothing. The established suppliers sell to large organisations and are too expensive and too slow to set up for the customers we serve.

Why this team wins

Catalina was a hydraulic engineer at a water utility for eight years, so the team knows the buyers by name. Matías built the core technology, and the first customers came by referral.

Headline metric

14 active users, growing 13% a month

The team

Catalina knows the customer and has sold to them before; Matías has built this kind of system at scale. We have worked side by side since before Aqualine had a name.
