Zoeller Company
Zoeller built an 87-year business around a machine most people notice only when it stops. Its edge is not novelty for novelty's sake, but obsessive testing, contractor trust and a family portfolio that follows water almost everywhere it needs to go.
Aprisium
Aprisium is a Singapore deeptech startup that builds on-site, real-time contaminant detection systems for water and other fluids. Using patented electrochemical sensors paired with AI analytics, it lets water utilities, industrial manufacturers, data-center operators and shipping firms detect pollutants - including heavy metals and PFAS - at the source in minutes rather than shipping samples to a lab and waiting days. The company raised an oversubscribed US$7M Series A in 2024 and deploys across Singapore, the Philippines and Australia.
