Company profile
researched Sep 2026TENX Pro, operating as TENXPro Pty Ltd in Australia and as TENX Sports in its US storefront, designs and produces tennis equipment including racquets, strings, grips, bags, accessories and stringing machines. Its racquet line centres on two families: XCALIBRE, positioned for power, control, feel and comfort, and XSTRIKE, an all-round frame offered in junior 26-inch and 270g, 285g, 300g and 315g weights. String products include Atomic Strike, Fusion Blast and Hex Touch; grips are sold under the ProTac and ProSoft names. The company also sells promotion packs and coach packs.
The products are built around uniflex, a racquet flex technology the company says applies 17 layers of carbon laminates to produce uniform frame flex and a target RA stiffness, with the stated aims of reducing frame vibration and improving power, control and precision. The company publishes customer survey and third-party review material, including a 2020 XCALIBRE customer survey conducted with Tennis Australia, a Tennis Australia string comparison report referencing Atomic Strike against Luxilon, Yonex and Babolat strings, and video reviews from Tennis Spin, Tennis Nerd and former Australian No. 1 Richard Fromberg.
An external company listing describes TENX Pro as an e-commerce and sporting goods business founded in 2017 with 1-10 employees at the pre-seed stage, with locations in Sydney and North Sydney, New South Wales, and Greenwich, Connecticut.
Business model
TENX Pro manufactures and sells its own branded tennis equipment directly to end users through regional online stores, positioning the direct channel as a way to avoid third-party costs. Alongside direct retail it runs a coach reseller program with a "Coach Direct Service" that offers coaches margins, special client pricing and direct parcel delivery to their clients, plus a member program and a player sponsorship program.
Revenue comes from online product sales of racquets, strings, grips, bags, accessories and stringing machines, priced per item (for example, XCALIBRE and XSTRIKE frames at $219.50 in the US store, XSTRIKE junior at $125.00 and the 270g at $205.00), supplemented by reseller sales through affiliated coaches. A TENX Membership and account registration grant a 10% discount on all products and access to package offers.
Traction
The US storefront displays customer review counts on individual racquet models, including 43 reviews each for the XCALIBRE 315G and 300G and 31 and 24 reviews for the XSTRIKE 315G and 300G. A 2020 XCALIBRE customer survey reported that 98% of surveyed players had recommended or intended to recommend the racquet. The company reports 1-10 employees and a pre-seed stage on an external company listing.
Latest developments
For the period 14-18 January 2026, TENXPRO products were included in a "Gamified Rebate" promotion sponsored by Baotris, Inc. dba PlayAbly and offered to US residents aged 18 or older, under which qualifying purchases of $100 or more made through playably.ai would be fully refunded if an American woman reached the Australian Open singles final; the promotion was explicitly not sponsored by or affiliated with the Australian Open or Tennis Australia. The US site also lists a demo section and shows items such as stencils marked coming soon.

Market position
TENX Pro positions itself as offering professional-grade racquet quality to all players rather than only high-profile professionals, competing in a category where its own published string comparison references Luxilon, Yonex and Babolat. External third-party validation cited by the company includes the 2021 Tennis Nerd "Spin Racquet of the Year" award for XSTRIKE and Tennis Australia-linked survey and lab analysis.
The company differentiates on its proprietary uniflex uniform-flex frame construction with 17 carbon laminate layers, and on a direct-to-consumer and coach-reseller distribution model that it says removes third-party costs and passes savings to members and coach customers.
Technology
The core product technology is uniflex, an in-house racquet flex construction applied across the racquet range. The company describes it as an advanced uniform flex frame construction using 17 layers of carbon laminates with a calibrated RA stiffness, intended to deliver a plush feel, reduced frame vibration, control and precision, with individual frame design elements optimised in relation to one another. Strings are marketed on blends of power, spin and comfort, including a 1.25mm Atomic Strike polyester monofilament.
Go-to-market
Sales run through localised Shopify-style storefronts with currency options in AUD, EUR, GBP, USD and CAD, free domestic shipping above set thresholds (AUD 150 in Australia, USD 99 in the US) and flat-rate international shipping. Customer acquisition channels include a membership discount program, coach reseller and affiliate applications, player sponsorships for aspiring competition players, social media accounts on Facebook and Instagram, third-party racquet reviews, and promotional campaigns such as the January 2026 PlayAbly gamified rebate tied to the Australian Open.
Recreational and competitive tennis players, including junior players served by a 26-inch frame, aspiring competition players eligible for sponsorship, and tennis coaches who resell equipment to their clients.
Geography
Headquartered in Sydney, New South Wales, with listed locations in North Sydney and Greenwich, NSW, Australia and Greenwich, Connecticut, USA. It operates an Australian store and a separate US store (usa.tenxpro.com) with US and Canadian currency options, and ships internationally with dedicated flat-rate international shipping from both regions.
History
An external company profile gives a founding year of 2017. Product and endorsement milestones referenced on the company's site include the XCALIBRE customer survey conducted with Tennis Australia in 2020 and the 2021 Tennis Nerd Spin Racquet of the Year award for XSTRIKE. The company has since expanded into a separate US-facing storefront operating as TENX Sports and ran a US consumer rebate promotion with PlayAbly around the January 2026 Australian Open.
