Heuristic Capital
Heuristic Capital is an early-stage, hardware-focused venture capital firm in Santa Clara, California. It backs founders building frontier technology, novel materials, and medical and consumer devices, not water specifically. (don't) Waste Water tracks two water-relevant hardware bets, Larq and WaterBit, and rates its water commitment Occasional as of 2026.

The take
Heuristic Capital is a hardware investor first, and that one fact is the whole key to reading its water record. Founding Partner Michael Liao has spent more than twenty years backing companies that make physical things, from novel materials to frontier devices, and the firm writes its early cheques where atoms matter more than software. So water shows up here only when water is a hardware problem.
Heuristic Capital's two water-relevant bets both fit that mould exactly. Larq makes a stainless-steel drinking bottle whose cap cleans the water inside it with a built-in UV-C LED, which is really a consumer-electronics take on clean water, and WaterBit builds solar-powered soil-moisture sensors that let a grower irrigate by the square foot instead of flooding a whole field. Neither is a water-treatment company; both are devices that happen to touch water, which is precisely what you would expect from a fund that thinks in sensors, batteries, and materials.
Heuristic Capital started up in 2016 in Santa Clara, right in the middle of Silicon Valley's hardware belt, and closed a roughly 34 million dollar debut fund in 2018 to back early-stage frontier-tech founders. Its three managing directors read as a hardware-and-healthcare shop rather than a water one: Liao the long-time hardware investor, Shu Cao the engineer who co-founded one startup acquired by Yahoo and another that listed on the NYSE, and Ren Du, a physician turned investor. For a water founder, Heuristic is a long shot with a very specific shape, because it will look at water sitting inside a device, but never water as infrastructure.
Heuristic Capital has not added a new water-relevant company since 2020, and that is why (don't) Waste Water rates its water commitment Occasional rather than core. The open question is whether the next wave of water hardware, cheap sensors and point-of-use purification and edge devices, pulls a hardware-native fund like this one back to the category more often than the once-in-a-while cadence its record shows today.
