Good afternoon,
Most parents will pay £50/month to save their kid’s GPA. Most landlords will give you free space to differentiate their building. Most developers will pay £299/month to avoid writing documentation. Today: Three ideas that tap into desperate buyers with real budgets


Homework Tutor: The £50/Month Lifeline
Parents panic when kids are failing. They'll drop £3-10k annually on tutoring centers like Kumon, but hate the commute and rigid scheduling.
Enter the AI tutor: subscription-based homework help for £50/month. Take a photo of the problem, get step-by-step explanations (not just answers), track progress, send weekly reports to parents.
The magic? It guides students through problem-solving like a real tutor would. No cheating, just learning.
The numbers: 71 million K-12 students, £15B tutoring market, 21M already using tutoring services. Parents will pay £30-75/month for unlimited help.
Go-to-market: Start with parenting subreddits and TikTok showing grade improvements. Then leverage the ultimate growth hack—desperate parents at school pickup lines.
Why it works: You're 85% cheaper than tutoring centers, available 24/7, and curriculum-aligned. GPT-4 is finally good enough to teach. Parents are comfortable with AI now.
The exit: Prove it works, get school partnerships, expand to test prep and college essays. Target £600k ARR year one, then sell to Khan Academy or Duolingo.


Micro-Gyms: Free Real Estate, Pure Profit
Here's the arbitrage: apartment residents pay $50-150/month for gyms they barely use. Landlords have 1,500 sq ft of dead amenity space earning $0.
Connect the dots. Install a 24/7 gym in apartment buildings, charge residents $50/month, landlord gives you space for free.
The pitch to landlords: "I'll install a private gym at zero cost to you. You can charge higher rents and reduce vacancy. I handle everything—equipment, insurance, maintenance."
Unit economics per location: $47k upfront (equipment + buildout), $600/month overhead, 50-60 members at $50/month = $2,000-2,400/month profit. Payback in 20 months.
The scale play: Once you prove it in 5-10 buildings, franchise it. Charge $25k franchise fee, take 30% royalty on membership revenue. At 100 locations, you're making $60-90k/month recurring.
Why now: Post-pandemic behavior favors hyper-local convenience. Remote workers are home more. Landlords need differentiation. Used equipment is cheap.
The comp: Anytime Fitness went from 1 gym to 5,000 locations using the same convenience-over-amenities playbook. You have better economics.


Auto-Generated API Docs: Developers Will Pay to Avoid Writing
Every company with an API needs documentation. Every developer hates writing it. Current options suck: manual Markdown files that go stale, ugly Swagger output, or $500+/month enterprise tools.
The solution: Connect your GitHub repo, get beautiful interactive docs in 5 minutes. Auto-updates when code changes. No manual work.
Pricing: Freemium for public repos. $29/month for basic, $99/month for pro features, $299/month for teams. Enterprise at custom pricing.
The market: 27 million developers, 5 million companies with APIs, $2.5B market potential. Current leaders like ReadMe are at $15M ARR but expensive and complex.
Go-to-market: Launch on Hacker News with "I built the tool I wish existed" angle. Open-source the free tier for marketing. Let individual developers adopt, then they convince their teams.
Why you win: Simplest onboarding (one-click GitHub connect), automatic sync (no maintenance), beautiful output (Stripe-quality docs), 10x cheaper than alternatives.
The defensibility: Integration depth with popular frameworks, switching costs once docs are live, become synonymous with "automatic API docs."
