Aceii is launching Aceii One, an intelligent tennis ball machine that feels like hitting with a live partner. Unlike traditional machines, Aceii One combines dual-camera vision to track every shot in real time, rapid baseline movement to reposition instantly, and a dual-stage serving system that delivers lifelike spin, speed, and placement at intervals as fast as 0.5 seconds. The result: unpredictable, human-like rallies that turn solo practice into real match play—while also keeping training engaging with global app challenges, personalized coach feedback, and a portable design that folds into the size of a 20-inch carry-on.
“Until now, tennis players had to choose between predictable ball machines and the challenge of live practice. Aceii One changes that balance by bringing AI-powered intelligence onto the court,” said Ricky Liu, Founder and CEO of Aceii. “Our vision is to empower players at all levels with professional-grade training that is realistic, accessible, and portable.”
What Makes Aceii One Different
Aceii One is built on the idea that real progress in tennis requires more than repetition. True growth comes from a balance of drills for consistency, match play for adaptability, and coaching for guided improvement. By uniting these three pillars into one system, Aceii One delivers a full-circle training experience that mirrors how athletes train with human partners. This structure ensures players build reliable fundamentals, sharpen competitive instincts, and receive personalized feedback — all in one portable carry-on device.

Solving the Pain Points of Traditional Machines
Predictable feeds and broken rhythm
Traditional machines act like feeders. Aceii One varies pace, placement, spin, and depth—down to 0.5 s intervals—to create lifelike rallies instead of repetitive shots.
Limited patterns, no real progress
Where others deliver the same ball each time, Aceii One offers one-click drill modes and fully customizable settings (speed, spin, placement, tempo), scaling from beginner to advanced play.
Slow and complicated setup
Instead of long adjustments, the Aceii App provides ready-made templates and saved routines. Start practicing in seconds, not minutes.
Bulky and hard to move
Aceii One folds into a 20-inch carry-on with wheels and a handle. Its ball bag doubles as a backpack, making transport effortless.
Poor adaptability and long downtime
Compatible with hard, clay, and grass courts, it deploys quickly with minimal setup.
Battery anxiety
Delivers up to 8 hours of stationary feeding or around 2 hours of intense rally play—enough for any practice session.
Robotic feel, no real pressure
A dual-stage serving system and fast repositioning create unpredictable rallies that demand real footwork and timing.
Solving the Pain Points of Players
No partner, no match-level training
Aceii One plays back like a live opponent. Smart Rally uses dual cameras and AI to read your position and return shots across the court.
No feedback, unclear improvement path
Every stroke and movement is tracked. With AI guidance plus real coach video lessons, players see progress and next steps clearly.
Private lessons are costly, limiting frequency
High-frequency, low-cost training frees coach time for tactics and details while Aceii One handles repetition.
Boring, repetitive sessions reduce motivation
Built-in challenges, ranking, and community sharing make practice engaging and goal-driven, sustaining consistency over time.
