Lino Leiden, an 18-year-old with zero coding experience, built AbMax — an app that generates personalized abs workout plans — and scaled it to ~$60K/month in 5 months through a combination of niche positioning, equity-based creator partnerships, and paid ads on Meta and TikTok.
The app and its traction
AbMax asks users for basic fitness info, then delivers a custom abs plan plus pre-made programs (e.g., “Summer Ab Shredder,” a 30-day plan).
Current metrics: ~$55K monthly revenue, 16K downloads in the last 28 days, 3,000+ active paying subscribers.
The app includes an “abs scan” feature that estimates lower-ab score, body-fat percentage, and identifies whether the limiting factor is body fat or muscle mass.
Finding the idea
In February, Lino went to the gym with friends; everyone kept comparing abs.
He researched and found no dedicated app in 2026 for people who specifically want visible abs — only general workout trackers.
He decided to build a niche solution targeting that exact desire, effectively remaking the old “5-minute abs / Bowflex” infomercial concept for the social-media era.
Building process: from zero code to shipped product
Started in Lovable (no-code AI builder) in February; spent 2 months prompting but felt the result was unreleasable.
Discovered the app-founder community on X (Twitter), learned “vibe coding,” onboarding tactics, and marketing fundamentals from successful founders.
Rebuilt the entire app in Vork in 1 month; launched V2 and did $7K+ in the first month.
Age 18, dropped out after first semester of college; no prior technical background.
Tech stack (kept intentionally simple)
Supabase — authentication and backend
VorkMax — development environment
Sensor Tower — competitor and niche research
sign.com — creator contracts and equity agreements
PostHog — internal product analytics
Marketing: zero to $10K/month
Early mistake: paid big fitness influencers for UGC without a proven creative format; margins were 5–10%.
Parallel effort: manually posted faceless TikTok slideshows; combined with UGC, got to $3–4K/month.
Breakthrough: partnered with one large fitness influencer for equity instead of cash.
Gave the creator skin in the game; content became “free” and higher-effort.
This equity partner provided the initial distribution engine to reach ~$10K/month.
Scaling: $10K to $60K/month
Cut all other UGC/influencer deals; doubled down on Meta ads running at 2–2.5x ROAS.
Kept only the equity creator producing content; ran paid ads strictly behind his creatives on Meta.
Tested the same creatives on TikTok ads — performed 4–5x ROAS (5–6x better than Meta).
Paid ads + one committed creator became the scalable, profitable loop.
Lino’s 5-step app playbook (if starting over)
Step 1: Join the X app community. Follow top founders; they share detailed, actionable advice for free.
Step 2: Validate with Sensor Tower. Search niche keywords; if multiple apps consistently do >$10K/month, the niche is proven.
Step 3: Post before building (organic validation).
Create a faceless TikTok page; post 3–4 slideshows/day for 7 days.
Slides deliver value (e.g., “5 ways to improve your life”); final slide says “Comment ‘app’ and I’ll send it” instead of a link.
If comments pile up, demand is real — then build.
Step 4: Ship in 7 days. Build in Vork (or preferred tool); launch fast. Obsessing over features pre-launch is the #1 mistake (Lino lost 2 months on V1).
Step 5: Find micro-influencers for creative testing.
Search niche keywords on IG/TikTok; target creators with 500–1K followers who post consistently.
Pay ~$100 for 10 videos each; test hooks, formats, CTAs to find a winning style before spending big.
Step 6: Scale marketing.
Hire a VA (Fiverr) to cold-DM hundreds of creators (criteria: 5–50K followers, shows face, active comments, consistent posting).
Get 10–15 creators posting consistently → build creative library → run paid ads behind winners (UGC campaigns via platforms like SideShift Tribe or manual management).
Step 7: Revamp product after marketing is stable. Once at $5–10K/month with profitable ads, hire a developer/engineer to rebuild properly. Product obsession belongs post-traction.
Library of pre-made programs (e.g., Summer Ab Shredder, 30 days).
Lino claims first-mover advantage: “zero competitors in this niche.”
Final advice
Don’t compare your Level 2–3 to someone else’s Level 10. Focus only on your next step.
You will hit moments that feel like “life is over”; in retrospect they’re small.
Persistence compounds: if you never quit, show up daily, and get 1% better each day, “it’s physically impossible for you to lose.”
Pat & Gus reflections
The idea seems “almost unbelievable” (abs app in 2026?), yet it works — proves there are countless monetizable niches hiding in plain sight.
No secret marketing genius required: Lino took action, learned publicly on X, failed fast, iterated, and wasn’t afraid to look foolish.
The core problem (people want abs for summer) is timeless; the delivery mechanism (VHS → app) changes. Same pattern applies to many other evergreen desires.
