I turn evidence, structure, and a builder's discipline into products that help people come back stronger — most recently a native iOS app built end-to-end with AI-assisted development.

Featured Project

A product taken from idea to investment-ready.

Lazarus is a native iOS app I scoped, designed, and de-risked end-to-end — strategy, clinical safety logic, evidence base, and a full financial pro forma — using AI-assisted development with Claude and Claude Code. What remains is the build.

Return-to-Training · iOS v1

Lazarus

"Come back stronger, at your own pace."

A native iOS app for people returning to training after injury, surgery, illness, pregnancy, or a long break — rebuilt around a dual-axis adaptive engine that scales every session to both a person's starting point and their daily energy and soreness, inside a small accountability circle.

The Product

Problem — comeback training is generic. It restarts people too hard, or gives them no structure at all.

Solution — a dual-axis adaptive engine plus a one-buddy accountability circle. Core loop: intake → adaptive session → log → streak.

ADAPTIVE ENGINE — evidence-informed, not clinically validated

  • Starting tier from experience × time off
  • Daily readiness — energy + soreness (1–7) + pain override
  • Safety gates — 12-week postpartum block; injury restrict-area

Go-to-Market & Model

  • Practitioner referrals, community, content, ASO, and a built-in buddy loop
  • Free tier + Premium at $9.99/mo or $79.99/yr · 7-day trial
  • ~$35/mo infrastructure · break-even ≈ 54 subscribers
  • $12K self-funded across 4 milestone-gated tranches · no debt
  • Positive NPV in every modeled scenario (worst ≈ $11.7K)

Recommendation: PROCEED — fund $12K, pass the month-one gate before scaling spend, re-run monthly.

Work completed — 11 documents

Strategy, engineering, clinical safety, governance, and finance — documented and de-risked before a line of production code.

About Me

Business sense, behavioral science, and a builder's hands.

I'm Luke McGreevy — a founder and builder based in Pennsylvania. My background is unusually broad on purpose: a degree in Business Administration Management, international business study in the Netherlands, years in applied behavioral science teaching and mentoring others, and front-line healthcare during the height of the pandemic. The throughline is people — understanding how they learn, recover, and change behavior.

Today I channel that into building products. I went deep on AI-assisted development — earning Anthropic's full Academy track and a University of Michigan Python certificate — and used those tools to take Lazarus, a native iOS return-to-training app, from a blank page to an investment-ready plan: product spec, adaptive safety engine, evidence register, governance, and a full financial pro forma.

As an NASM Certified Personal Trainer, I care personally about helping people come back from injury and setbacks — which is exactly the problem Lazarus is built to solve. I work with discipline, document everything, and stay honest about what's evidence-informed versus proven.
