Jeremy McCann is a CSCS-credentialed strength coach who has spent nearly two decades in the highest-pressure performance environments in professional sports and special operations. He is also, as of five weeks ago, a SaaS founder.
Jeremy McCann holds a Certified Strength and Conditioning Specialist (CSCS) credential from the NSCA — the standard of practice for elite-level performance coaching. He has spent 18+ years working with athletes and operators at the highest levels of their fields.
That career has taken him to Major League Baseball with the Los Angeles Dodgers and Miami Marlins, onto the PGA Tour, and into the weight rooms and training programs supporting U.S. Army Special Operations units — organizations where the performance margin between good and great is measured in fractions and the cost of failure is real.
Today he runs JM Health & Performance — a premium remote coaching practice with 26 active clients. One-on-one. High standards. No filler.
Worked inside Major League Baseball organizations where performance data is obsessive and programming precision is non-negotiable. Load management, in-season maintenance, and off-season development at the professional level.
Performance coaching for tour-level golfers. Rotational power, injury resilience, and the unique physical demands of a sport where athletes compete 30+ weeks per year. Programs built around tour schedules, not around convenience.
Strength and conditioning support for Army Special Operations units. Programming for operators where physical readiness isn't a fitness goal — it's a job requirement. High stakes, zero margin for error.
Built a focused, high-touch remote coaching practice. 26 active clients. Individualized programming, deterministic progressions, and the kind of attention that generic apps and group coaching can't replicate.
Jeremy didn't become a software developer. He became something more useful: a domain expert who learned to wield AI as a development tool.
Five weeks ago, he had never written a line of production code. He had a clear vision for what his coaching software needed to do — a vision built from 18 years of working with athletes generic platforms couldn't serve. Auto-progression engines. RPE-free load calculations. Deterministic periodization algorithms. A knowledge base built from real coaching, not fitness influencer content.
Using multi-AI workflows and a structured development approach — the same framework now available through DomainForge — he shipped Strength Foundry: a production SaaS that does exactly what no generic platform could ever do.
That experience is the proof of concept for DomainForge. Not that AI replaces developers — but that a domain expert with the right framework can build software that no developer, without that domain knowledge, ever could.
DomainForge exists because the tools didn't. Jeremy spent years routing around bad software — platforms that didn't understand progressive overload, CRMs that treated athlete check-ins like customer service tickets, apps built for the average user when his clients were anything but average.
Generic SaaS was built for the middle of the market. That's not where domain experts live.
DomainForge is the framework, the methodology, and the hands-on guidance that turns your expertise into custom software. Not a template. Not a white-label. Your domain knowledge, encoded into your product, shipped to production.
It worked for Jeremy. The same process works for coaches, therapists, contractors, and any solo operator who knows their field well enough to know that no off-the-shelf tool will ever do it justice.
