In 2021, the partners found a home for their idea-building at a 6,000-square-foot blighted industrial facility on Binghamton’s east side, which they upgraded with assistance from the city’s economic development department. The following year, the City gave them their first big break, utilizing their material Pantheon™ in sidewalk upgrade projects, reusing glass placed at the curb by Binghamton residents for new construction on those same streets.
Other state entities factored into their journey, as they refined and strengthened their business. KLAW’s inclusion in the 2021-22 cohort for the NYSERDA-backed Scale for Climate Tech, helping hardtech cleantech startups, is “one of the strongest programs we have been a part of,” Kumpon says. And a NYSTAR-supported FuzeHub manufacturing grant allowed them to purchase KLAW’s signature yellow truck in 2023.
Kumpon describes the truck, a dry bulk pneumatic trailer, as “basically a big soda can” that prevents contamination of the Pantheon™ powder, which it transports from KLAW’s production facility to concrete plants. “This FuzeHub project allowed us to scale our manufacturing to tractor trailer-level volumes and fit into our customers’ regular supply chain,” he says.
The company marked a major milestone in 2024, with the New York State Department of Transportation approval of KLAW’s Pantheon™ product for use in state projects—its strength evidenced in the NYSDOT’s U.S. Route 11 bridge replacement in the Village of Whitney Point. Quoted in the Governor’s announcement of the project, Kumpon said it reflected a “commitment to developing and utilizing the best materials available for our infrastructure. The collaboration between NYSDOT and our local contractors has brought great attention to the work here in Whitney Point and is a hallmark example of performance-based decarbonization in the industry.”
In September 2025, through NYSTAR's Innovation Matching Grants Program, ESD further bolstered federal funds the company had received from the U.S. Environmental Protection Agency’s Small Business Innovation Research (SBIR) program. KLAW was one of 25 New York-based businesses awarded grants in Round 3 IMG program funding, allowing the company to complete a facility expansion, grow their glass supplier network and solidify their mission of bringing sustainable materials into the concrete industry mix.
"This project with ESD was a massive step for us. It allowed us to expand our operation in Binghamton and grow our workforce,” Kumpon says, “and seeing our company transition from a startup to a full-scale operation is extremely rewarding for the team here."
Kumpon also is paying it forward, by giving local students a chance to learn on the job. Bryant Patterson, a Maine-Endwell high school senior (Class of 2027), has honed his welding skills through the Broome-Tioga BOCES Career & Technical Education Welding program. Patterson has worked part-time during his school week and Kumpon describes him as already one of KLAW’s best fabricators.
“What I enjoy most about working at KLAW and learning the trades is how every day is hands-on, and you get to be a part of the outcome you're producing,” Patterson says. “Every day we're learning something new and pushing the boundaries of our skills.”
Seven years after Kumpon’s idea took form, KLAW is now in a growth stage. Today, KLAW supplies Pantheon™ to concrete producers across New York and has expanded into equipment manufacturing, helping concrete producers and recyclers across the U.S. bring glass-processing technology to their markets.
"Throughout our story, there have been many people who have helped us grow to where we are today. One of the unique things about New York is that the people behind these programs genuinely care and are invested in your success. When you're a founder at 19 trying to figure it out, that makes all the difference."
