🐄 Engineer Liam Kampshof turned an early milking-shed prototype into a simple, low-cost sensor now used on 145+ New Zealand farms, catching mastitis early to protect milk quality and payouts!

Liam is a New Zealand tech entrepreneur and founder of Bovonic, makers of QuadSense—a snap-in, battery-powered sensor that measures each teat’s conductivity in real time, compares quarters, and throws a red light in ~30 seconds if mastitis is likely. It retrofits into the short milk tube, has no moving parts, a ~3-year battery life, and costs ~5× less than legacy lab systems—so farmers actually install it. 🐄 Mastitis 101: why manual “stripping” fails at scale and how quarter-level conductivity catches it earlier.

📈 Adoption: ~145 farms (≈2% NZ) in year one; near 5% in early regions; hardware + profitability.

🧭 NZ edge: no subsidies → ruthless ROI; “number-8 wire” practicality meets biomedical chops.

🥛 Macro: NZ = #1 dairy exporter (not producer); EU cell-count standards and antibiotic rules shaping demand.
