Seattle's Neat lands a $400,000 Shark Tank deal with Lori Greiner
The sweat-hiding T-shirt brand took Greiner's offer of $400,000 for 15 percent plus 75 cents per order until she earns her money back.

Jim Huffman and Tyler Stelter of Seattle apparel maker Neat secured a deal with Lori Greiner on Wednesday night's episode of ABC's Shark Tank, GeekWire reported Thursday. Greiner agreed to invest $400,000 for a 15 percent stake, plus 75 cents per order until she earns back her investment. Huffman told GeekWire the paperwork is still being finalized. The founders had asked for $400,000 for 5 percent.
Neat's shirts use a patented Sweat Maze lining that pulls moisture inward so it dries before it shows through. The technology came out of National Science Foundation research originally aimed at military and first-responder gear. Net sales grew more than 300 percent in 2025 to about $700,000, and Huffman said the company is on track for $1.5 million to $2 million this year. Neat has four employees, two in Seattle and two in Portland, makes shirts in Vietnam and sells direct to consumers. Site traffic jumped about 20-fold as the East Coast and Central segments aired, Huffman said.
