How a 15-Year-Old Builds a Real Business in 90 Days (Sebastian's Plan)

⚡ Las Vegas · May 2026

A 15-year-old, a trampoline gym, and a 90-day plan to start a real business.

This week at Ninja Kids in Las Vegas, I played trampoline basketball with Sebastian — 15 years old, a football player, and an aspiring entrepreneur. Between dunks, we sat down with Claude and built him a plan. Here’s the whole thing.

Step 1 — His unfair advantage

The Venn diagram has almost nobody in it.

Most football creators are 35-year-old dads who can barely make a thumbnail. Most AI-native teens don’t know a Cover 2 from a Tampa 2. Sebastian is in the overlap. That’s the entire business.

Football players (millions) AI-native teens (millions) YOU are here The overlap is small. That’s why it’s worth money.
Two huge audiences. Very few people sit in both. That’s leverage.
🏈

He actually plays

He spots what’s fake. He knows which drills work. Authenticity is the #1 thing the algorithm rewards.

He moves 10x faster

A 35-year-old “football guy” takes 3 hours to script a video. Sebastian takes 20 minutes with ChatGPT. That math compounds.

⏱️

3–5 hours is a feature

Short-form rewards consistency over polish. Limited time forces him to ship instead of overthink.

💻

Laptop is enough

Every tool he needs is free. He’s not waiting on money, gear, or permission. Start tonight.

Step 2 — The business model

Four phases. Each builds on the last.

Don’t try to monetize on day one. Build the audience first, then stack income streams on top of it. Here’s the realistic money curve.

$0 $100 $1K $5K $10K+ M 1–3 M 4–6 M 7–12 Year 2 Year 3 build first $ $100-1.5K real money upside zone
Money is flat for 3 months. Then it climbs. Most people quit before the climb. Don’t.
1

Months 1–3 — Build the channel

No money yet. The product is him learning to ship. Get to 50 videos posted. Find his voice.

💰 Realistic: $0
2

Months 4–6 — Turn on small monetization

Amazon Associates for football gear (parent signs up, Sebastian runs it). Start the newsletter. First brand DMs.

💰 Realistic: $20–$200/month
3

Months 7–12 — Stack income streams

Newsletter → digital products (drill PDFs, recruiting guides) → first paid brand deals.

💰 Realistic: $100–$1,500/month
4

Year 2+ — Real upside

Sponsorships, his own training app or community, long-form YouTube. This is where it gets serious.

💰 Realistic ceiling: $1K–$10K/month if he stays consistent
Step 3 — Pick his lane

One niche. Pick tonight.

Pick the one that makes him most excited to make 5 videos this weekend. Don’t overthink — he can pivot in 60 days. Indecision is the killer.

A

Football IQ

30-sec videos explaining one play, concept, or moment per day. “Why Mahomes throws sidearm.” “What a Cover 3 actually does.” Easy to script with AI.

B

Train Like a Recruit

Drills + recruiting tips for middle/HS players. Smaller audience but way more monetizable (gear, training apps, programs).

C

AI Predicts Football

Use AI to predict matchups, breakout players, the next 5-star recruit. The hook is the AI itself. Football + tech crossover.

Step 4 — The 90-day plan

What he does, month by month.

Each month is ~12–16 hours total. Batch the work on Sunday. Post throughout the week.

Month 1

Foundation

  • Week 1 (3 hrs): Pick niche, name the channel (ChatGPT can brainstorm 20 names), make accounts on TikTok/YouTube/IG.
  • Week 2 (3 hrs): Use ChatGPT/Claude to generate 20 video ideas → script 7 of them in 30-sec voiceover format.
  • Week 3 (4 hrs): Download CapCut. Watch one tutorial. Record voiceover (his voice or ElevenLabs). Pull b-roll from Pexels. Auto-caption. Post video #1 + #2.
  • Week 4 (3–5 hrs): Post daily. End of week, check the top video’s 3-sec hold rate. Make more like it.
End-of-month milestone: 15+ videos shipped. Probably under 500 followers. The real win: he’s figured out his shooting routine.
Month 2

Consistency

  • Daily or 5x/week posting. Don’t break the streak.
  • Save 2 hrs every Sunday to script + shoot the week’s 5 videos.
  • Apply for Amazon Associates (parent signs up). Drop one affiliate link in bio.
  • Start free ConvertKit account. Add “Get my weekly breakdown” to bio. Just collect emails — don’t send yet.
End-of-month milestone: 30+ videos total. 1,000+ followers on one platform. 20+ emails. Maybe $5 affiliate. Not the point yet.
Month 3

Compound

  • 50+ videos total by month-end.
  • Send the first newsletter. Then commit to weekly.
  • Make a free PDF (“10 Drills Every HS Football Player Should Do”) with ChatGPT + Canva. Use as a lead magnet.
  • DM 2 small football brands: “I have X followers, can I post your product for free product?”
End-of-month milestone: 50+ videos. 2K–10K followers. 50+ subscribers. First gear partnership or $50–$100 affiliate month.
Step 5 — The AI toolkit

Every tool is free. Every one runs on his laptop.

Total monthly cost to start: $0.

Step 6 — Reality check

The stuff nobody tells 15-year-olds.

Read this carefully. It’ll save him a year of frustration.

💳 Money + the law

He can’t legally open Stripe/PayPal under 18. Parent signs up, he runs it. Be 100% transparent with them — this is his advantage, not a workaround.

📊 Track everything

Every dollar. Every view. Every hour. Google Sheet from day one. When tax stuff matters in 2 years, he’ll be glad.

⏰ Consistency beats intensity

3 hrs every week > 10 hrs one week and 0 the next. Batch on Sunday, post throughout the week.

🎓 Don’t quit school

He’s not escaping — he’s building options. The kid with 50K followers by senior year has more college and job options, not fewer.

🚪 The quit zone

90% of creators quit between day 30 and 60. The algorithm rewards almost nobody early. Around video 40–80, something clicks for those who stayed.

🛡️ Stay safe

No last name. No school. No address. No school logo in any gear. Faceless = identity-less. Parents back you harder when you handle this proactively.

Step 7 — Start tonight

His first 7 days, exact actions.

If he does nothing else this week, do this. The hardest part is video #1. Once he ships it, everything after is reps.

✅ The Week 1 Checklist

DAY 1
Tonight: Pick Option A, B, or C.

Write it on a sticky note. Stick it on the laptop.

DAY 2
Brainstorm 30 video ideas with ChatGPT.

Use this prompt: “I’m a 15yo who plays football. I want to make 30-second faceless videos about [your niche]. Give me 30 video ideas with strong 3-second hooks.”

DAY 3
Script your first 5.

Pick the 5 favorite ideas. Have AI write 30-second scripts. Read each out loud. Cut anything that sounds robotic.

DAY 4
Make accounts.

TikTok + YouTube + Instagram. Same handle on all three. Use Canva to make a simple logo.

DAY 5
Learn CapCut.

Watch one 20-minute tutorial on YouTube. That’s enough. Start editing video #1.

DAY 6
Post video #1.

Don’t wait until it’s “perfect.” Post it. Immediately start editing video #2.

DAY 7
Post video #2. Tell one trusted adult what you’re building.

Accountability is fuel. Pick someone who’ll ask you next week.

Bonus — How to use AI on this plan

Make this plan work harder for him.

Open ChatGPT, Claude, or any AI he likes, paste this plan, and use prompts like these to make it his own.

🎯

“Help me pick the niche”

“Here’s my plan. I’m torn between Option A and B. Ask me 5 questions to help me decide, then recommend one.”

💡

“Generate this week’s content”

“Using the niche I picked, give me 7 video ideas + 30-second scripts in my voice (15yo who plays football, casual but smart).”

📈

“Score my progress”

“I posted 8 videos. Top one got X views, bottom got Y. What patterns do you see? What should I make more of?”

🚀

“Tune the plan”

“I’m 30 days in. Here’s what’s working: ___. Here’s what’s not: ___. Rewrite Month 2 of this plan for me.”

For A-players — The AI Builder Program

If Sebastian wants to skip the solo grind.

The plan above works. I’ve watched it work for hundreds of young adults. But doing it alone — staring at video #15 with 11 views — is the hardest version of this game. So Dylan Haugen and I built the AI Builder Program at Local Service Spotlight — a one-year apprenticeship for US-based young adults who want to run real marketing for real businesses.

What the program actually is

📅

Weekly live coaching

Every Thursday at 2 PM Pacific with me, Dylan, Jack Wendt, and rotating coaches.

📚

140+ courses

Google Ads, Facebook Ads, GBP, Maps Visibility, Content Factory, AI agents — updated as tools change.

👥

400+ AI Builders

Active Facebook group running 24/7. Someone’s always awake to help.

💼

A real client from day one

If you don’t have one, we give you one. Plumbing, roofing, HVAC, dental, landscaping.

The proof: A-players who came through

MARKO SIPILÄ

CoatingLaunch + HVAC Quote

Zero to 100+ clients and a seven-figure run rate in under 5 months. Then launched HVAC Quote — 300 paying customers in under a year. From $50K in debt to $45K/month profit.

GEORGE PALADICHUK

NaiL — AI Call Center

Still a college student. Built an AI call center to $70K/month — a million dollars of ARR. Recovered $400K in booked jobs in a single month for one fencing company.

ETHAN VAN DE HEY

Roofing Launch

Added $30M in revenue to a single roofing company in one year. Grew Infinity Exteriors from $45M to $65M. The Mr. Beast of roofing. 26 years old.

BRENNAN AGRANOFF

HoopSwagg

Made his first million by age 16 making custom socks in his parents’ garage. Featured on CNN. Today runs a seven-figure sock company, a logistics company, and a software company.

None of these people are unusually smart. They’re committed. They show up. They submit the report on Friday. They run the playbook.

⚡ Apply to the AI Builder Program

⚡ One thing to do tonight

Pick Option A, B, or C.
Then ship video #1 this week.

Sebastian said he likes football, hard work, and money. This plan is built around all three. Football is the niche. Hard work is the engine. Money is the scoreboard — it shows up later than he wants.

The kids who win this game are the ones who post video #87 when video #1 through #86 each got 12 views.
That can be Sebastian. That can be your kid.

For parents reading this

If you have a teen who’s hungry like Sebastian: don’t fund the dream. Don’t buy the course. Don’t pay for the camera. Make them prove they’ll show up for 90 days with what they already have. The kid who’ll do that with a $0 stack is the same kid who’d do it with a $5K stack. The kid who needs the $5K stack to start is the kid who won’t finish.

Your job is the legal scaffolding (Amazon Associates account, PayPal, eventually an LLC) and the safety guardrails. The hustle, the reps, the showing up at video #87 — that’s their job, and they have to want it. If they do, you’ll know within 30 days. And when they prove it — that’s when the AI Builder Program becomes the right next step. We don’t take kids who haven’t already shown they’ll show up. But the ones who do? We make them dangerous.

Sebastian — your first video is due Sunday. I want a link in my inbox by Monday morning. We’ll review video #15 together in 30 days. Go ship.
