Is Your Child on Track?
Science-backed insights to help you and your child’s team make informed, timely decisions about training and development.
A Letter to Our Parents
Hi Parent, and Welcome to MatCalc.
My name’s Bob. I’ve worked in professional sport since 2005 — over 15 years as a strength & conditioning coach, and now several more managing athlete data systems for the England & Wales Cricket Board.
I’m also a parent of three young children, and we’re just beginning our own journey into youth sport. Despite my coaching background, I still find myself with the same questions and doubts many of you may have:
How hard should I push? When do they need protecting? Am I doing what’s best for them — or risking doing too much?
Why We Built MatCalc2.0
MatCalc2.0 is the result of real, lived experience — mine as a coach trying to manage squads of young athletes, all on different timelines, in elite performance environments.
It’s hard. Each child grows and matures differently. And staying on top of it all — knowing who needs what and when — is a mountain of work for any coach. Maturation is just one piece of a very complex puzzle.
But from the parent’s side? It’s no easier. You want clarity. Confidence.
You want to understand what’s happening with your child’s development — and how to work with their coach or team to support them at every stage.
That’s exactly what MatCalc2.0 is here to help with.
Reports Designed for You — and With Your Child in Mind
The reports we create are built for you, the parent — to read with your child. They’re as clear and engaging as they are informative, while being honest about what these predictions can (and can’t) tell you.
Because these are early years. There’s still a lot ahead.
What We’ve Done
I partnered with George — the tech wizard behind the platform — to take the Kamis-Roche model used by top coaches across sport and supercharge its predictive power.
George has transformed our everyday challenges into a smarter, more secure platform that gives coaches real insight — and gives you the tools to stay connected and informed.
It’s a huge step forward in how coaches and teams can support your child through their most important years of development.
But We Also Knew: We Had to Get Privacy Right
We’re proud that MatCalc2.0 is not just a leader in prediction and insight — but in data privacy and ethics, too.
From the very start, we’ve invested in legal guidance on GDPR and gold-standard security practices.
But even more importantly, you are in control:
- Only you, the parent, can create your child’s profile.
- Only you can link it to a school, club, or team.
- If your child changes school or switches teams? You simply remove access.
- That organisation’s view of your child’s history is wiped — but you retain everything.
That’s the right thing to do — for your child, for you, and for everyone involved.
Collaboration, With You at the Centre
Having worked inside elite sports environments, I can tell you: communication between parents and teams is one of the biggest challenges.
MatCalc2.0 is designed to change that — to create transparency and collaboration between you and the teams supporting your child, always keeping you in the loop and focused on what matters most: your child’s wellbeing and development.
We’re always improving our tools, refining our predictions, and supporting the teams that support you.
From George and me, thank you — and we wish you and your child all the very best in their journey.
Warmly,
Bob & George
Co-Directors, MatCalc
