Built by someone who got tired of guessing.
Mallet exists because health data is everywhere and answers are nowhere. Your labs sit in a PDF, your training in one app, your food in another, your recovery on your wrist. Nothing talks to anything, and no one tells you what to actually do. Mallet connects all of it and turns it into a clear next step.
Hi, I'm Matthew.
I'm the founder of Mallet. I played Division I lacrosse on scholarship, and ever since then, performance and health have never really left my head. These days I'm a husband and a father first, which only sharpened the question that started this whole thing: how do I actually stay strong, healthy, and around for a long time, and how do I prove it with data instead of vibes?
As an athlete I had coaches, trainers, and a system. The day that structure goes away, you are handed a pile of disconnected tools and left to be your own coach with no playbook. I had bloodwork I half understood, a wearable that gave me a score with no instructions, and a notes app trying to hold it all together. I was tracking everything and learning almost nothing.
I'm obsessed with sports, fitness, health, and tech, so I did the obvious thing for someone like me. I built the system I wished I had. Mallet is the coach for the part of life where no one hands you one.
What Mallet actually does
Mallet brings your whole health picture into one place and reads it as one system, not as a dozen separate apps:
- Bloodwork mapped to longevity-optimal ranges, not just clinical “normal,” plus a biological age from your panel.
- Training, nutrition, and recovery tracked together, so a change in one is read against the others.
- Supplements and peptides with interaction checks, so your stack is not quietly working against itself.
- An AI assistant that reads all of it and tells you the one thing worth doing next, instead of leaving you to guess.
Where I'm coming from
I'm not a doctor, and Mallet is not medical advice or a substitute for your physician. What I bring is the lived experience of being an athlete who had to become his own health manager, and a builder's obsession with making the data clear and honest. Everything I write on this blog is meant to help you understand your own numbers and ask better questions, then take what matters to the people who care for you.
