Kleen Hub is a Copenhagen-based circular tech company building Tap & Reuse™ — a frictionless reuse system that makes reusable packaging work at scale. Our platform combines simple hardware with a lightweight software layer to enable fast, reliable reuse without the usual barriers: no app, no user registration, and no deposit handling required. We help venues and operators (cafés, campuses, stadiums, airports, corporate sites and more) replace single-use packaging with reusable cups and containers through an operationally simple setup. Tap & Reuse™ supports multiple return flows (smart return stations, return bins, handheld scanning and washing-site verification), delivers high return rates in closed and semi-closed environments, and provides clear reporting for operations and ESG. Kleen Hub works with leading partners and distributors across Europe and has deployed systems in high-volume environments, proving that reuse can be convenient for users and manageable for staff. Our mission is to remove friction from reuse and accelerate the transition away from single-use packaging — by making reuse as easy as tapping a card.

Perma Padel is on a mission to become a leading global racket sports brand and equipment manufacturer, defined by an unwavering commitment to premium performance, sustainability, and innovation. Perma Padel is the first to apply a novel industrial manufacturing process for padel rackets using 100% recyclable thermoplastic carbon fiber, unlocking a new era of performance, sustainability, and scalability. By moving from manual labor to precision automation, we slash manufacturing time significantly, while delivering a product that is twice as durable as the competition. Our Core Innovations Include: MonoFrame™: A supercar-inspired unibody design that removes the traditional hollow internal frame. This creates a stronger racket with a larger, more forgiving sweet spot. OmniCore™: High-grade foam from edge to edge. This eliminates dead zones, maximizes energy return, and significantly reduces vibration to lower the risk of injury. FutureFiber™: Our proprietary thermoplastic carbon fiber allows for a fully circular model. Unlike toxic epoxy-based rackets, our materials are 100% recyclable and enable zero-waste manufacturing. We have already secured a launch partnership with Denmark's biggest retailer and have an organic waitlist of over 700 players. We are currently finalizing product development for a Summer 2026 launch.
