Short-chain PFAS capture, Waterloo, Canada
The smallest PFAS, the short and ultra-short-chain ones, slip straight through today's water filters. Sunriser invents the materials that finally catch them, pairing an AI discovery engine with a real materials lab, and concentrates them so a destruction partner can finish the job.
Where we point the engine
01The thesis
PFAS are everywhere, in the blood of nearly everyone and the water of millions, and they do not break down on their own. The big ones are catchable. The small ones, the short and ultra-short-chain PFAS, are not. They have almost nothing for a filter to grab, so they slip through ordinary carbon and travel farther than anything else. Canada and Europe are now regulating exactly these.
Catching them is a materials-design problem. It takes an engineered material with the right charged sites to grab a tiny, slippery molecule while ignoring all the ordinary salts in the water. Nothing on the market does this well. Finding that material the old way is slow: mix something, measure it, try again, for years.
Two things just changed. AI can now predict which nanostructures are worth making, which narrows an enormous search before anything gets built. And a small team can pair that prediction with a real lab to check it, so the gap between an idea and a proven material closes in days instead of years. Sunriser is built on that loop, pointed at the PFAS nothing else can catch.
02Research
We start where a better material is the bottleneck and the buyers are already motivated, and right now that means PFAS in water.
We catch what everything else misses.
Engineered sorbent materials that selectively capture the short and ultra-short-chain PFAS that granular carbon and today's best filters break through on. This is our flagship, an urgent, regulation-driven problem where the smallest, most mobile forever chemicals are the ones no material catches well.
ExploreWe pull value out of brine and waste.
Selective materials that pull lithium and other critical minerals out of brines and waste streams. They turn a disposal cost into a product, on a supply chain the world is racing to bring closer to home.
ExploreWe pull clean water and useful material from hard streams.
Membranes and sorbents for the high-value industrial separations that conventional treatment handles poorly. They recover clean water and useful material from streams that others write off.
ExploreThis is where the engine goes next.
Catalysts for clean energy, advanced sensing, and more sustainable nanomaterials. These are the broader set of materials problems the same discovery loop can take on once it has proven itself on the first ones.
Explore03The engine
Our engine is a closed loop. AI proposes the nanostructures worth making, the lab builds and measures them, and every result trains the next round of predictions. What makes the company durable is the speed and learning we build around this loop. No single material does that on its own.
AI and inverse-design models start from the property we need, such as a PFAS-binding site or a selective channel, and propose the candidate nanostructures most worth making. That narrows a vast search before a single sample exists.
We fabricate and synthesize the top candidates in a real materials lab, with the process discipline to make the same material twice.
Characterization verifies what was actually built and how well it works, and every measurement feeds back to sharpen the model, so each cycle is faster and smarter than the last.

The new PFAS limit
US regulators now cap some forever chemicals at about four parts per trillion in drinking water, a wall utilities must now clear.
>98%
Of people carry PFAS
Forever chemicals are detectable in the blood of nearly everyone tested, and they don't break down on their own.
From years to days
The loop we're building
An AI and lab discovery cycle aims to turn a materials search that once took years into one that runs in days.
04The team
The discovery engine needs both halves, the AI and production software on one side and the hands-on nanomaterials science on the other. Sunriser is founded by two people who cover both, and we are hiring around them.
Co-founder & CEO
Runs the company and builds its software. He spent a decade in B2B sales, growth, and full-stack product, and has since put thousands of hours into building production tools with AI, the same kind of systems that now power Sunriser's discovery engine and its day-to-day operations.
Co-founder & CSO
Leads the science and the lab. He is a nanotechnology engineer, trained at the University of Waterloo with an M.Eng. from Western, with hands-on depth across nanofabrication, electrochemistry, membranes, and the full materials-characterization stack, from design through fabrication to measurement.
Ecosystem & lab
We are building inside the Waterloo deep-tech ecosystem, one of the strongest startup and nanotechnology clusters in the world, with a bench of water, materials, and deep-tech operator advisors forming around the company.
