Hi, I’m Matt — founder of DEEP
I grew up in a house where dinner conversations were about glycemic index and magnesium absorption. My family owned a health food store, and from the time I could read labels, I was reading them. Whole foods, supplementation, what your body actually needs versus what a marketing department says it needs — that was the air I breathed. Decades later it became something more deliberate: biohacking, recovery science, sleep optimization, nutrition tracking. The thread has always been the same. What does the data actually say, and what should I do with it?
I built DEEP because the answer to that question shouldn’t be locked behind $400 wearables, paid coaches, and twelve different apps that don’t talk to each other.
What I bring to this
Lifelong biohacker. Wearables, supplementation protocols, sleep tracking, HRV trending, continuous glucose monitoring — I’ve tested most of it on myself before any of it goes near the app. If a feature is in DEEP, I’ve used it on my own data. The Sleep Bank, the multi-signal illness detector, the personal-baseline math — those aren’t whiteboard ideas. They came out of nights I was sick, weeks I was overtrained, mornings I needed an honest answer instead of a green ring.
Endurance athlete. I’ve completed Iron-distance triathlons — a 2.4-mile swim, 112-mile bike, and 26.2-mile run, all in one day. You don’t finish one of those without obsessing over recovery, hydration, fueling, and sleep. Every variable matters because every variable can break you at mile 90 of the bike. That’s where my respect for the data was forged: not in theory, but in the back half of long races where the numbers either add up or they don’t.
Coach for 20+ years. I’ve volunteered as a high school football coach for over two decades. Coaching teenagers means meeting kids where they are — the kid who’s never trained, the kid grinding for a college scholarship, the kid showing up exhausted because home is hard. That work shaped a conviction that runs through every screen of DEEP: a great training program is one the athlete can actually follow, with feedback loops they can actually understand. If you can’t see what changed and why, you can’t adjust.
Builder. DEEP — the iOS app, the backend, the publishing pipeline, the AI coach, the analytics — is built end-to-end by a small team I lead. Owning the stack means I can move fast on the things that matter: a new readiness signal, a smarter sleep score, a feature that turns a confusing chart into a single sentence you can act on.
Why DEEP exists
Pro athletes have teams of nutritionists, sleep coaches, recovery specialists, and sports scientists. The rest of us have a Fitbit and Google.
That gap is what I want to close. The ability to track and adjust your health metrics — sleep, training, nutrition, recovery — should not be a luxury good. It should be the default. The science exists. The sensors exist. The data exists. What’s been missing is a tool that ties it all together for the person who doesn’t have a coach on call.
DEEP is for the kid I coach who can’t afford a Whoop. For the parent who’s trying to fix sleep on top of two jobs. For the lifter who’s pushing hard but doesn’t know if they’re overtraining. For me at mile 90. One app. One readiness score. One honest picture of how you’re actually doing today, and what to do about it tomorrow.
That’s the whole pitch. I’m glad you’re here.

How I write
Articles are grounded in peer-reviewed research. I cite primary sources where possible — meta-analyses, randomized controlled trials, and systematic reviews from journals like Sleep, Sleep Medicine Reviews, the Journal of Strength and Conditioning Research, and the European Journal of Applied Physiology. When evidence is contested or thin, I say so.
How I do not write
I do not give medical advice. Nothing on this site is a substitute for a clinician who can examine you, run labs, and make individualized decisions. If you have a medical condition or are training around an injury, talk to a professional.
Corrections & feedback
If I got something wrong — a number, a citation, a claim — email support@deep-app.co. I’ll update the post and add a “Corrected on” note in the byline.
Editorial independence
I do not run sponsored content. The only product I promote is DEEP itself, which I build. App Store links use attribution parameters so I know which articles drive installs, but recommendations are not bought.
