Street Art Hunt — One-Pager

Inspiration

Date-Night Spark

  • Text-only scavenger dropped three restaurant coupons to my phone.
  • Zero app installs; me and the missus wandered parts of London we’d normally skip.

Graffiti Pivot

  • I’m a street-art nerd.
  • Swapped food clues for mural clues but kept the discount loop.
  • Quick history blurbs keep the architecture fans happy.

What It Does

SMS-Only Scavenger Hunt

  1. Pay via Stripe → instant deep-link: sms:+44...?&body=START-HUNT.
  2. Entire game plays out via plain SMS—no WhatsApp, no apps.
  3. Each correct answer unlocks a micro-perk at an indie spot a minute away.
  4. Backend logs every answer + timestamp so we can spot friction and tweak clues fast.

Blog & UGC Flywheel

  • Players upload mural photos, tag the spot; backend spins a mini-blog post.
  • Best pic each week wins a free tour.
  • Fresh posts boost SEO → more eyeballs → new players.

How We Built It

Lean Stack

  • Supabase – routes, answers, partner offers, auto-blog CMS
  • Twilio SMS – two-way clue messaging
  • Stripe – one-click checkout
  • Started in Nuxt; UI was rough → GPT generated React components in a weekend.

Data Edge

  • Open03 scraped every indie business within a two-minute walk of each mural.
  • Dedicated landing pages for every partner now rank for “<Partner Name> discount.”

Challenges We Ran Into

Challenge Fix
Nuxt UI looked stuck in 2009 Swapped to GPT-built React
LLM token burn Tight modular prompts + caching
Van blocking a key mural Added backup clue + alt route
Owners unsure about offers Showed live Google clicks + QR redemption plan

Accomplishments We’re Proud Of

  • MVP shipped in 48 hours—fully wired checkout and SMS flow.
  • Partner pages are already on page 4 of Google after just three days (zero backlinks).
  • First Brick Lane owners interested; offer discussions underway.
  • UGC pipeline live—first test uploads tagged and blogged.

(No paying customers yet, and that’s fine—ranking this fast is win #1.)

What We Learned

  • Ideas are free; finishing them takes sweat.
  • SMS beats apps for friction-free experiences.
  • AI’s the sous-chef; human taste still matters.
  • Tracking every answer lets us iterate routes in real time.
  • Hidden history + fresh art = repeat-worthy combo.
