The Future ofTennisIs Here.
Three breakthrough brands. One holding company built to end 150 years of stagnation in tennis technology. MADDAN Corp owns the patents, the science, and the platform that changes the sport forever.
The Problem
150
years of the same design flaw.
The Solution
We engineered
a molecular fix.
Diels-Alder reversible chemistry — furan and maleimide groups that recombine at crack sites when frictional heat is generated on impact, sealing micro-cracks within seconds to minutes. The same platform extends to strings and frames via Patent #3.
Self-healing core — 99.8% pressure retention after 500+ games
Nano-felt cover — 3× durability, 98% less microplastics
3 interlocking patents filed April 2026
90%+ waste reduction at 10% market adoption
The Science
Four Breakthroughs.
One Platform.
Hover each tab to explore the technology stack behind MADDAN's three interlocking patents.
Self-Healing Core
Diels-Alder Chemistry
Furan and maleimide groups embedded in the elastomeric core recombine at crack sites when frictional heat is generated on impact — sealing micro-cracks within seconds to minutes. The ball literally heals itself mid-game.

The MADD Ecosystem
One Platform.
Three Revolutions.
Maximum Adaptive Durable Design. The same self-healing and nano-composite platform — extended across every product a tennis player touches.
The Ball That Outlasts the Game.
MaddBall
The world's first self-healing tennis ball. Diels-Alder reversible chemistry repairs micro-cracks on every impact. One MaddBall replaces 10–20 conventional balls.

The Same Breakthrough. Applied to Your Strings.
MaddStrings
Self-healing coatings and nano-composite reinforcement for 2–3× longer string life and less notching. Patent #3 — the MADD platform extended to racket strings and frames.

Sustainable Performance. Inside and Out.
MaddLife
Sustainable tennis apparel and accessories under the MADD brand. The same first-principles thinking — built for multiple lifecycles, not single use.

Three Patents.
One Ecosystem.
Self-Healing Core
Diels-Alder reversible bonds in the elastomeric core. Furan and maleimide groups recombine at crack sites on impact — sealing micro-cracks within seconds.
Filed April 2026Nano-Felt Cover
Silica nanoparticles and graphene oxide reinforce the felt surface. 3× abrasion resistance. 98% less microplastic shedding. 54+ games of felt life.
Filed April 2026Strings & Frames
The same platform extended to racket strings and frames. Self-healing coatings for 2–3× longer string life. Cross-references Patents #1 and #2.
Filed April 2026Together, the three patents protect a category — not just a product. 17+ years of utility patent protection.

Interlocking Patents
Filed April 2026. Self-healing core, nano-felt cover, strings and frames. 17+ years of utility patent protection.

Sustainability
Built for the
Planet. Not Just the Court.
At 10% market adoption, MaddBall eliminates over 90% of tennis ball waste. Aligned with the ITF Sustainability Roadmap, EU Circular Economy Action Plan, California SB 1383, and ATP/WTA carbon-neutral commitments for 2030. The incumbent dilemma is our permanent advantage — Wilson, Head, and Penn make $1.7B/year on replacement sales. They cannot innovate without destroying themselves.
The Future Is Now
Chemistry

About MADDAN Corp
Built in a Lab.
Proven on the Court.
MADDAN Corp is a Delaware C-Corporation and the parent holding company of the MADD ecosystem. Three provisional patents filed. Dual-track GTM built. Seed round launched. All before raising a dollar.
The category window is open now. The incumbent dilemma is permanent. The IP thicket is filed. The only question is execution velocity.
The Window Is Open Now
$5M to Own
a Category.
MADDAN Corp is raising $5M at a $12M–$15M pre-money valuation. 18+ months runway to first revenue and ITF approval. Every dollar is tied to a milestone. Distribution partners, investors, and pro-tour contacts welcome.
