Founder (CEO) - Elemental Sensing for AI Data Center Cooling

Who We Are

ATUM is a Singapore deep-tech venture builder and investor. We build companies from breakthrough, IP-backed research, bringing capital, operational muscle, and partners from industry, VC, and government into every build. We've built and backed 15 ventures, and we invest in fast-scaling deep-tech with real fundamentals, not hype.

The Venture

Liquid cooling is fast becoming the backbone of the AI data center, and the coolant running through it is now mission-critical. Yet the fluid is still watched the way it was decades ago: a sample sent to a lab, once a quarter, or after something has already failed. Corrosion doesn't creep evenly either. It jumps when a loop gets topped up with the wrong fluid or an inhibitor runs down, and quarterly sampling finds the damage months later with no way to trace the cause.

We're building the company to change that.

The core is an inline coolant-monitoring platform, developed at NTU, that uses laser-induced breakdown spectroscopy to read the coolant in real time, identifying and quantifying the dissolved metals that signal corrosion, down to which component is degrading and how fast. The optical monitors entering the market today read the fluid indirectly; this one measures the metals directly, which they cannot.

The first market is coolant monitoring for data center operators, where a reliability gap is opening fast as the industry shifts to direct liquid cooli
