What StringKing does

StringKing is a privately held multi-sport equipment and custom-fit apparel manufacturer founded in 2011 by Jake McCampbell and Luke Aronson in Medfield, Massachusetts, and currently headquartered in Gardena, California, with production and warehouse operations in Los Angeles. The company began with high-performance lacrosse mesh and has expanded its product portfolio to include men's and women's lacrosse heads, shafts, sticks, mesh, strings, accessories, and protective gear; BBCOR, USSSA, and USABat-certified baseball bats; fastpitch and slowpitch softball bats; and senior and intermediate hockey sticks. In 2020, during the COVID-19 pandemic, the company pivoted manufacturing capacity to produce 150,000+ masks per day, securing high-volume contracts with the Defense Logistics Agency to supply masks and hospital gowns to the U.S. Army, U.S. Marine Corps, and U.S. Navy, and establishing itself as a domestic apparel manufacturer for military branches and the U.S. Postal Service.

The company's strategic differentiator is the Perfect Fit Algorithm, a proprietary custom-fit apparel platform that applies machine learning trained on more than 25,000 three-dimensional body scans representative of the North American population. Customers complete a six-question questionnaire; the algorithm predicts body dimensions with 97%+ accuracy, an automated design system generates the corresponding garment measurements, and the design is laid out on fabric and cut by laser cutter for made-to-order production in Los Angeles, shipping within 2-3 days. Custom apparel is offered in premium fabrics including Peruvian Pima Cotton, Tencel-polyester blends, and performance synthetics, priced between $49.99 and $69.99 per garment, while sports equipment is priced between $49.99 and $179.99 per unit and gift cards are issued in $25, $50, $100, and $250 denominations.

StringKing's revenue model is multi-stream: direct-to-consumer e-commerce via stringking.com with order management and account tools, a team sales and onboarding program for sports organizations, a retail partner network with store locator, international shipping to Canada, Mexico, and worldwide, custom-fit apparel made to order, and government apparel contracts. The company is the Official Partner of the National Lacrosse League (NLL), is supported by professional athlete endorsements (including Matt Gibson), and markets through organic social media, email, YouTube video content, SEO, and paid remarketing via Google Ads and Meta Pixel. The company is founder-owned, structured as String King Lacrosse LLC, with no disclosed institutional investment, parent entity, or acquisition activity.
