NeuroTennis Wearable Tech

Summary

Cam Lickle, US Naval Academy graduate (5 years active duty), former tennis entrepreneur, and co-creator of two tennis industry initiatives, joins Lisa Stone to discuss two products: NeuroTennis (a wrist-worn wearable that delivers coach-customized audio reminders triggered by ball strike events during play) and Global Tennis Professionals (GTP), a coach-player association with a deferred payment contract structure designed to address the sport’s endemic free-lesson-and-abandonment cycle. The episode covers the technical architecture of NeuroTennis (240 pre-built instructions, Matt Vilander and Lauren Davis voice packages, coach-customizable commands, Bluetooth-networked dual-mode), the coaching philosophy behind it (anything requiring constant repetition requires constant reminders), and the business logic of GTP (sweat equity deferred payment contracts, five-year payment plans, third-party enforcement, public coach-player relationship records). Together, the two initiatives represent a rare example of a tennis insider attempting structural reform of both the on-court development product and the economic relationship that surrounds it.

Guest Background

Cam Lickle grew up playing tennis in New England (then NELTA), attended the United States Naval Academy, played tennis for four years there, served five years active duty (no tennis during that period), then left the military to pursue tennis professionally. He became a business partner of Matt Vilander — a former world number one wheelchair tennis player — on the WOW (Wheels on Wheels) initiative that traveled the country bringing tennis to communities. He subsequently co-created NeuroTennis (launched August 2020 after six years of development through approximately ten prototypes) and Global Tennis Professionals (GTP), a coaching accountability association. He discovered the need for GTP after personally experiencing a coach-player contract dispute in which he found no institutional body — not the ITF, not the ATP — willing to intervene in civil coach-player matters.

Key Findings

1. NeuroTennis: Wrist-Worn Coaching Reminder Device

The core product: a wrist device worn during practice or play that senses ball strike events and delivers pre-programmed audio coaching instructions through a speaker. Technical architecture: the device does not know whether the player executed correctly — it simply senses the action and delivers a contextually relevant reminder (e.g., after hitting a ball: “back to the middle,” “watch your opponent,” “stay low while moving”). Two operating modes: single mode (one device) and dual mode (two networked devices, where one player’s strike triggers a reminder for the other). 240 pre-built instruction options. Available voice packages: default generic male voice, Matt Vilander voice (“Do It Like Davis” for women with Lauren Davis), and coach-customizable voice recordings for player-specific needs. Launched August 2020, developed over six years through approximately ten prototypes (the racket throat mounting was abandoned due to weight imbalance; final placement is on the wrist). Available at neurotennis.com.

2. The Core Coaching Principle Behind the Device

Lickle’s one-sentence philosophy for the device: “Anything that requires constant repetition requires constant reminders.” His application: a coach cannot be on court with a player every moment, and the gap between sessions is where bad habits re-form or good habits fail to consolidate. NeuroTennis fills that gap — specifically targeting the 80% of practice time when the coach is not physically present. The device is explicitly not a replacement for coaching (“we’re trying to reinforce what the coach is teaching”) but a bridge between sessions. Coaches can record their own voice with specific player-targeted instructions (e.g., “keep your left arm up on the forehand,” “step into the backhand with your front foot”).

3. Non-Judgmental Feedback as a Coaching Innovation

Lickle identifies the device’s non-judgmental quality as a structural advantage over coach-player real-time feedback. When a coach tells a player to move their feet in an escalating, frustrated tone, the player eventually starts fighting the coach rather than working on the movement. When the device delivers the same reminder, “he’s not fighting with the coach — he’s just not doing what he’s supposed to do, and there’s no one to blame except himself.” The emotional charge of corrective feedback is removed from the player-coach relationship and placed on the device, preserving the relationship for higher-order coaching interactions.

4. The Coach-Parent Bridge Function

Lisa Stone surfaces an application Lickle hadn’t foregrounded: NeuroTennis as a transparency mechanism between coaches who exclude parents from practice and parents who feel shut out of their child’s development. If the coach customizes the device with their specific teaching priorities for each player, parents can access the coach’s current curriculum through the device rather than requiring court access. The coach retains control over technical instruction; the parent stays informed about what the child is working on. This application is unbuilt but logically available in the existing product.

5. GTP: Deferred Payment Contract Structure for Coach-Player Relationships

Global Tennis Professionals (GTP) is a coach-player association with a specific structural innovation: deferred payment contracts that allow families to access high-quality coaching at volume without requiring full up-front payment. The model: player and coach negotiate a rate, the coaching is delivered, and payment is deferred over a five-year plan with the first payment not due until one year after the conclusion of services. GTP serves as the third-party that holds both parties accountable — enforcing contracts, maintaining public records of who coached whom (so coaches cannot claim relationships they didn’t have, and cannot be erased from players’ development histories), and creating a “find a coach” database searchable within a 100-mile radius. Available at globaltennisprofessionals.com (also GTP.com).

6. The Structural Problem GTP Is Solving

Lickle describes two failure modes in the current tennis coaching economy. On the parent side: families take coaching for free from coach A, the player improves, they leave for coach B (who is more prestigious or cheaper), and coach A is left with no compensation for the development work they did. Lickle: “Coaches hold players like their possessions because they do everything for free and feel like they own you.” On the coach side: coaches who give free lessons eventually stop coaching honestly — they become “yes men” who won’t push a player for fear of losing the relationship they’ve subsidized. GTP’s deferred payment contract is designed to restore professional accountability to both sides by making the coaching relationship a formal, documented, enforceable economic agreement. He references the Naomi Osaka / coach Christophe lawsuit as the cautionary case: “He deserved $100,000 back for $100,000 of coaching — but not $1 million.”

7. The Tennis Industry Economics Problem

Lickle identifies tennis as structurally unusual among professional services industries: coaches with elite résumés undercharge, undervalue their time, and compete in a race to zero that leaves the most experienced coaches subsidizing player development. His specific provocation: “We are the only industry where someone who coached 10 top-100 players will do it for $50 an hour, and the next coach says he coached 20 top-100 players and will do it for free.” He compares this to attorneys who charge $300/hour even while thinking about a client between sessions. GTP’s public records system is designed to give coaches verifiable credential records — so they no longer have to rely on self-promotion or the charity of players who may or may not credit them publicly.

Actionable Advice for Families

• If your child’s coach is developing specific priorities for each session, ask the coach whether they would consider using NeuroTennis to allow the player to work on those same priorities between sessions — it reduces the parent’s burden to monitor technique and extends the coach’s impact hours
• If you are working with a coach who is giving reduced-rate or heavily discounted lessons in anticipation of future compensation, document that arrangement explicitly — verbal promises in a free-market sport with no enforcement body create the exact situation Lickle describes (the Osaka model: coaches left with claims and no records)
• Before choosing a coach, ask the coach how they document and protect their own coaching relationships — a coach who has thought about this is more likely to treat the relationship as a genuine professional partnership

INTENNSE Relevance

• Mic’d coaches: NeuroTennis is the wearable version of INTENNSE’s mic’d coach concept — a coach’s voice delivering tactical reminders at the moment of action, without requiring physical proximity; the bolt-arc coaching window is the structured version of what NeuroTennis does in open practice
• Technology integration: The NeuroTennis dual-mode (two networked devices, one player’s strike triggers a reminder for the other) is architecturally analogous to what INTENNSE could build into team substitution coaching — real-time positional reminders for players already on court, triggered by match events
• Coach compensation infrastructure: GTP’s deferred payment / public record structure is exactly what INTENNSE’s player-coach contracts should build in — the league’s documented coaching relationships (each coach of record for each bolt arc) create a verifiable public record of who coached whom, preventing the erasure of development contribution
• Player financial sustainability: Lickle’s critique of the free-lessons economy (“coaches become yes men because they’ve subsidized the relationship”) is the exact dynamic INTENNSE’s salaried player model disrupts — players on salary have no leverage to demand free coaching access, and coaches on contract have no incentive to avoid difficult feedback
• Lauren Davis: Named in the episode as a product ambassador (voice package “Do It Like Davis”), Lauren Davis is a US pro with direct NeuroTennis product association — relevant for any INTENNSE broadcast partnership that involves Davis
• Format innovation: The 240-instruction library that NeuroTennis pre-built suggests the coaching vocabulary for in-play reminders is finite and categorizable — INTENNSE could develop a similar taxonomy for between-bolt-arc coaching windows, giving coaches a structured menu of interventions rather than open-ended feedback sessions
