What's in this set
Water purification is a narrow filter in AngelMatch's pitch deck database right now, with a single company currently tagged to it. Folia Water's pitch deck shows a $150K seed round from 2017, and the deck is tagged across five categories: Advanced Materials, Consumer Goods, Emerging Markets, Paper Manufacturing, and Water Purification. That spread is a clue about how investors are likely to read a water purification pitch today: less as a standalone category and more as a materials-science or emerging-markets story that happens to solve a water problem. Folia's pitch describes chemically functionalized fibers built at the cost and scale of paper mills, which is the kind of manufacturing angle worth studying if your own deck leans on a novel material rather than a device or a service. Read the deck directly rather than relying on a summary here; it is the only real example tagged to this industry so far.
What investors look for in a water purification pitch deck
Manufacturing cost at scale. Folia Water's deck leads with fibers made using paper-mill-level processes rather than lab-only techniques, and that distinction matters because water purification investors weigh unit economics before impact framing. A treatment method that only works in small batches struggles to reach the price points this category usually targets.
Distribution into underserved markets. Folia's deck is tagged to Emerging Markets alongside Water Purification, and that pairing is typical for the category: many water treatment pitches promise safe drinking water where piped infrastructure is limited or absent. Investors expect a distribution and affordability plan sitting next to the technology slide, not standing in for it.
Third-party water-quality validation. A water purification claim is also a safety claim, so investors in this category expect evidence that filtration performance has been independently tested rather than only measured in-house. A seed-stage deck like Folia's needs to show that validation path exists even before it can point to years of field data.

Water purification is still a small slice of AngelMatch's pitch deck database, with one funded example and a combined $150K+ raised so far. There is no dedicated water purification page in AngelMatch's investor database yet, so the strongest next move is the broader investor list.
