Key people at Slinger Bag.
Slinger Bag is a sports technology company that designs and manufactures portable, affordable ball launchers and practice equipment primarily for racquet sports like tennis and pickleball.[1][2] Its flagship product, the Slinger Launcher, serves tennis and pickleball players by combining a high-capacity ball launcher with a multifunctional tennis bag that holds up to 144 balls, racquets, and gear, solving the problem of expensive, bulky training tools that limit practice accessibility.[3][8] The company has shown strong growth momentum, launching via Kickstarter in 2018, achieving $6.87 million in revenue and 10,069 units sold in its first 12 months (2020), cumulative tennis launcher sales exceeding $30 million by 2023, and expanding into pickleball with high demand.[4][5][6]
Slinger Bag emerged from a simple vision in 2017 (with some sources noting 2015 or 2020 launch): making tennis ball machines affordable and portable for every tennis enthusiast worldwide, driven by founders' passion for racquet sports.[1][2][5] The idea gained traction through Kickstarter and Indiegogo campaigns in May 2018, raising funds to develop the prototype into a production model after iterations in China.[4][6] A pivotal moment came in 2019 when Mike Ballardie, former tennis industry executive (ex-Prince), joined as CEO after testing the prototype and building production infrastructure; the first production units fulfilled 3,500 Kickstarter orders in March 2020, with market sales starting in July 2020.[6] Headquartered in Windsor Mill, Maryland, the company has evolved from a tennis-focused startup to a publicly traded brand (SLBG, later under Connexa Sports Technologies) expanding into pickleball and padel.[4][5]
Slinger Bag rides the wave of racquet sports resurgence, fueled by the COVID-19 pandemic's boost to outdoor activities and tennis/pickleball growth in markets like North America, Europe, Asia (China, Thailand, Vietnam, Korea), and Japan.[1][6] Timing aligns with demand for home-based, tech-enabled training tools amid club access limitations, leveraging e-commerce (Facebook/Google Ads) to dominate US rankings and achieve high ROAS (11.6x).[4] Market forces like pickleball's explosive popularity and lifetime sports trends favor its portable innovations, influencing the ecosystem by lowering barriers to entry—making practice "tennis on-demand" and helping grow participation without daunting club commitments.[6][8]
Slinger Bag is poised for continued expansion with pickleball sales potentially matching tennis, new padel products, and enhanced connected technologies to deliver immersive practice experiences.[1][5] Trends like AI-driven drills, global racquet sports growth, and e-commerce scaling will shape its path, potentially amplifying influence through partnerships (e.g., Dunlop) and international distributors.[3][6] As racquet sports evolve into connected ecosystems, Slinger could redefine accessible training, building on its sales smash to rival established players while keeping innovation portable and player-focused—echoing its founding goal of equipment for every enthusiast.[1][2]
