Summary

  • Max, a University of Michigan graduate with finance internships but no coding background, built Maxed AI — an all-in-one lifting and fitness app — in six months using AI coding tools, growing it to roughly $14–15K/month with a $24.99/year upfront price and no subscription reliance.

The app: Maxed AI

  • All-in-one health and fitness coach that tracks sleep, builds personalized workout programs, logs lifts, nutrition, supplements, and peptide protocols.
  • Central feature is the “Max Coach” chatbot wired to every component: adjusts workouts based on context (illness, fatigue), generates recipes from available ingredients, and keeps everything on one screen.
  • Includes social feed, leaderboards, and saved workout templates for accountability and competition.
  • 164 App Store ratings, ~20K iOS downloads all-time, 1,000 active subscribers, 20K+ new customers in the last 28 days.

Business model & metrics

  • Single upfront payment of $24.99/year (~$2/month) — deliberately avoids recurring subscriptions that rely on users forgetting to cancel.
  • MRR appears low because revenue is recognized upfront, not spread monthly.
  • Every cent of revenue is reinvested into growth (paid ads, creator program).

Differentiation in a crowded market

  • Unified platform: running has Strava and Nike Run Club; lifting lacked a single dominant app — Maxed aims to be that.
  • “Max Coach” chatbot integrates all features so users never leave one screen to check sleep, adjust programs, or watch tutorials.
  • Founder-led content creates community and loyalty that competitors cannot replicate.

Founder background

  • Graduated University of Michigan; two summer internships in finance (venture capital, sales & trading) — realized he had no passion for the work.
  • First attempt: a food review app called Dish Rate, abandoned after realizing development would cost tens of thousands.
  • In Dec/Jan, saw non-technical people building apps with AI; bought a $15/month Claude Code membership and started typing.
  • Has not gone a day without working in the terminal with Claude since.

Finding the idea

  • Not naive about 100+ competitors, but chose to build for a personal passion: lifting with friends throughout college.
  • Noticed lifting lacked a unified platform like running has; multiple fragmented apps existed but no clear winner.
  • Embraced naivety as an advantage — didn’t overthink incumbents’ head start.

Tech stack & costs

  • Claude Code ($20/month for 20 apps), Supabase ($20/month), Vercel, Expo (deployment/updates), RevenueCat (payments).
  • Total monthly tooling cost is minimal; barriers to entry are extremely low.
  • Advises anyone to start now — this is the best time ever to build an app.

Growth & marketing strategy

  • Early mentor (met via Instagram) advised: hard paywall from day one (no free tier, no ad monetization).
  • No budget for UGC creators → filmed himself daily (5–10 videos), pushed through cringe/fear of judgment.
  • Analyzed hold rates and skip rates on every video; turned best performers into paid ads.
  • Started with low ad budget; scaled to ~$250/day on Meta as product-market fit became clear.
  • Launching a “side shift” campaign to recruit five more creator-operators who film daily like he does.
  • Avoids hiring UGC creators early — need to know winning angles before spending.
  • Meta outperforms TikTok: higher-intent buyers, better demographic, higher willingness to pay.
  • Clipping (repurposing long-form into short clips) is still early on the wave and drives international organic downloads.

Personal brand & founder-led content

  • Started tweeting 3 months ago; roughly 1/3 of revenue comes from X followers tracking the journey.
  • Rejects “build in stealth” mindset: be public, show what works and what doesn’t, share vulnerabilities.
  • Authenticity and passion attract supporters who buy the app or cheer the journey.
  • Personal brand is the only true moat — features can be copied, founder story cannot.

App demo highlights

  • Home screen: schedule, today’s workout, saved templates, leaderboard rank.
  • Max Coach chatbot: text any request (adjust volume when sick, create protein dessert from pantry ingredients) and it updates the program or saves recipes instantly.
  • Social feed drives accountability and healthy competition.

Final advice for aspiring builders

  • Went “half in, half out” at first — afraid to market, attach name, or film himself.
  • Best advice: go all in, film yourself, annoy everyone with your obsession, document the journey.
  • Looking back at early videos (first paying customer → $15K/month) is one of the most rewarding parts.

Host reflections

  • Max’s energy and vibe stand out; success doesn’t require a crazy unique idea — lifting apps are simple, many exist.
  • The unreplicable edge is personal brand; founders should build publicly despite instinct to stay close to the chest.
