Idea #11: Build a Directory in One Evening, Sell for $15K in 3 Months

In partnership with

Hey buddy,

Today's WiFi Moolah idea is perfect if you can spot trending topics early and you're willing to build fast and ship imperfect products.

Niche Directory Websites

The Idea: Build a curated directory of businesses/tools in a trending niche, go viral on Reddit/Twitter/HN, monetize through premium listings and ads

Example: John Rush built AllGPTs in one evening for $10, got 2 million visitors in first month, made $10K revenue, sold for $15K three months later

Why it works:

• Pieter Levels makes $5.3M/year from Nomad List (started as simple spreadsheet in 2014, now 29K+ paying members at $75/year)

• John Rush has "multiple directories making around $5,000/mo" each

• AllGPTs got 2M visitors, 5K Discord members, 10K newsletter subscribers in first 3 months

• NextJS boilerplate directory: 73,000 monthly visitors organically

• Rodrigo Rocco's job board directory: $4,887 in November 2024

• People desperately need curated lists when new tools/categories explode (AI tools, SaaS boilerplates, remote jobs)

• Once traffic flows, mostly passive - John Rush: "requires near-zero maintenance and profitability"

• Speed wins - AllGPTs built in one evening, went viral next day

• Can be sold quickly - John posted he wanted to sell AllGPTs, got 3 DMs in 5 minutes

• First-mover advantage in trending niches is enormous (custom GPTs, AI tools, NextJS boilerplates all exploded)

Time investment: 1-3 days to build (if you move fast), then 2-5 hours/week for updates/content

Potential income: $2,000-15,000/month once established, OR quick exit for $15K-50K

Difficulty: Beginner-Intermediate (can use no-code tools, main skill is spotting trends early)

Startup cost: $10-100 (domain + no-code directory builder)

Where I found it: John Rush's AllGPTs case study showing $10K revenue and $15K exit in 3 months, Pieter Levels Nomad List at $5.3M annual revenue with 29K customers, multiple John Rush directories at $5K/month each, Rodrigo Rocco job board at $4,887/month

Tools you'd need:

• No-code directory builder (Unicorn Platform $8-49/mo - what John Rush uses, Directbase $19-79/mo, SpreadSimple $29-99/mo)

• Domain name ($10-15/year)

• AI for content generation (ChatGPT $20/mo or Claude for writing descriptions)

• Twitter/Reddit accounts (free - main traffic sources)

• Payment processor (Stripe 2.9% + $0.30 for premium listings)

• Optional: AI scraping tool to auto-populate listings

The catch:

• Timing is EVERYTHING - if you're 3 months late to a trend, you missed it

• Requires obsessive trend-watching on Twitter, Reddit, Hacker News

• Many directories get zero traffic (John Rush: "20 failed, 10 survived")

• Going viral is unpredictable - John Rush was "shocked" when AllGPTs exploded

• Most trending topics die quickly (GPT hype cooled off, traffic dropped)

• You need to ship in 1-3 days max or someone else will beat you

• Generic directories fail - must be hyper-specific trending niche

• Traffic comes from social media virality, not SEO (SEO takes months)

• Can feel like gambling - you don't know what will work until you try

• Revenue often starts at $0 for months (AllGPTs had "zero revenue" initially despite massive traffic)

My take:

This is fascinating because the winners win HUGE and the losers lose almost nothing (just time). John Rush built AllGPTs in one evening for $10, got 2 million visitors, and sold it for $15K three months later. That's a 1,500x return.

But the real insight is his portfolio approach: he launches 30+ directories, expects 20 to fail, and the 10 that survive each make $5K/month. That's $50K/month across the portfolio.

The key is being FIRST to a trending topic. When custom GPTs launched, John built AllGPTs the same night. When NextJS boilerplates exploded, he built nextjsstarter.com. He's not building better directories - he's just faster.

How to spot trending topics (John Rush's method):

• Search "what's best..." on Twitter, Reddit, Hacker News daily

• Watch Product Hunt - what types of products are launching 10x this month?

• Monitor Google Keyword Planner for search volume spikes

• Follow tech influencers who spot trends early

• Join startup/tech Discord/Slack communities

• Watch OpenAI, Google, Meta for product launches (custom GPTs, Gemini tools, etc.)

Profitable trending niches (as of Feb 2025):

• AI agents/autonomous agents (exploding right now)

• Local AI tools (running LLMs locally)

• AI video generators (Sora alternatives)

• Cursor alternatives (AI coding tools)

• Voice AI clones

• AI podcasting tools

• Vertical AI SaaS (AI for dentists, lawyers, accountants)

• Privacy-focused AI tools (after OpenAI controversies)

• AI image generators (post-Midjourney alternatives)

• Open source alternatives to popular SaaS (always evergreen)

My Verdict: Would I try it? Yes, but only if I spotted a trend EARLY. The $15K exit in 3 months is too good to ignore. But I'd launch 5-10 directories, not just one, because most will fail. This is venture capital logic applied to tiny bets.

If you want to explore this:

Week 1: Become a trend detective

1. Set up TweetDeck columns: "AI tools", "SaaS boilerplate", "remote work", "indie hackers"

2. Check Product Hunt daily - note which categories have 5+ launches this week

3. Join 3-5 relevant Discord/Slack communities (Indie Hackers, r/SideProject, etc.)

4. Google Keyword Planner - search for spikes in "[niche] tools" searches

5. Follow John Rush, Pieter Levels, other indie makers on Twitter

6. Goal: Build a list of 10 potential directory ideas

Week 2-3: Launch 3 directories fast

1. Pick your 3 strongest ideas (trending + low competition + you understand the niche)

2. Buy domains with exact match keywords ($10 each - "allgpts.com", "nextjsboilerplates.com" style)

3. Build on Unicorn Platform or Directbase (use templates, don't code from scratch)

4. Use AI to generate initial 50-100 listings (scrape public data, ChatGPT writes descriptions)

5. Create simple ranking logic (John Rush used backlink count for AllGPTs)

6. Ship all 3 in one week - imperfect is fine

7. Goal: 3 live directories, each with 50+ listings

Week 4: Go viral or die trying

1. Post on Twitter with catchy hook: "I spent 6 hours building [X], here's what I learned"

2. Submit to Product Hunt (time for 12:01am PST launch)

3. Post to relevant subreddits (r/SideProject, niche-specific subs)

4. Post to Hacker News as "Show HN: [Directory Name]"

5. DM relevant influencers: "Hey, I made this free directory of [niche], thought you'd find it useful"

6. Post to Indie Hackers, Dev.to, LinkedIn

7. John Rush viral tip: Don't link directly - mention the name, let people Google it (tells Google to rank you higher)

8. Goal: 10K+ visitors to at least one directory

Month 2-3: Monetize the winner

1. Whichever directory got traction, double down on that one

2. Add premium listing option ($99-299 for featured placement)

3. Add sponsor banner ads ($199-499/month)

4. Add affiliate links where relevant

5. Build email list (offer newsletter, tips, updates)

6. Keep adding listings (use AI to scale to 500-1,000 listings)

7. Goal: $1,000-5,000/month revenue OR get acquisition offers

The actual path successful directory owners take:

• John Rush (AllGPTs): Built in one evening when GPT store launched → Posted on Twitter → 100K views next morning → 2M visitors first month → Made $10K from sponsors → Sold for $15K after 3 months

• John Rush (OSS Software): Spent 1 hour finding keyword "open source alternatives" → Built directory in 1 hour → Posted to Dev.to and Hacker News with catchy title → 500K visitors → Ongoing passive income

• John Rush (NextJS Starter): Noticed 20+ NextJS boilerplates on Product Hunt → Built directory → 73,000 monthly organic visitors → $5K/month from affiliate links and sponsors

• Pieter Levels (Nomad List): Started as crowdsourced spreadsheet → Turned into simple website → Charged $5 to reduce spam → Kept raising price ($5→$25→$50→$65→$75/year) → Now $5.3M/year with 29K paying members

Pro tip: John Rush's secret viral hack - when posting on social media, DON'T link directly to your directory. Just mention the name. People will Google it, scroll down, find you, and click. This tells Google that people are searching for your brand specifically, which immediately boosts your ranking.

Pricing strategies:

Freemium model (recommended):

• Free basic listing (name, description, link)

• $99-299/month premium (featured at top, custom badge, highlighted)

• $199-499/month sponsor banner (homepage placement)

One-time boost model:

• Submit listing: Free

• Boost to top for 30 days: $49-99

• Works well for trending directories with high churn

Affiliate model (easiest, lowest friction):

• All listings free

• Add affiliate links where tools have programs

• Make 20-50% commission on sales

Money math:

Conservative scenario (3 directories, 1 succeeds):

• 10,000 monthly visitors to winning directory

• 3 businesses paying $99/mo premium = $297/mo

• 2 sponsor banners at $299/mo = $598/mo

• Affiliate income = $200/mo

• Total revenue = $1,095/month

• Less tools = -$50/month

• Net profit: $1,045/month ($12,540/year)

• Time invested: 5 hours/week maintaining

• Effective hourly rate: $52/hour

• OR sell directory for $15K-25K (18-24 months revenue)

Moderate scenario (Launch 10, 3 succeed at $5K/month each):

• Directory 1: AI tools directory, 50K monthly visitors

  • 15 premium listings × $149/mo = $2,235

  • 4 sponsor banners × $499/mo = $1,996

  • Affiliate income = $800/mo

  • Total: $5,031/month

• Directory 2: Remote job board

  • Job posts: 25 × $199/month = $4,975/mo

• Directory 3: SaaS boilerplate directory

  • Affiliate commissions on sales = $5,200/mo

• Total across 3 directories: $15,206/month ($182,472/year)

• Time invested: 15 hours/week across all 3

• Effective hourly rate: $253/hour

Aggressive scenario (John Rush / Pieter Levels model):

• Launch 30 directories over 2 years

• 20 fail completely (lose $200 in domains/time each = -$4,000 total)

• 10 succeed at $5,000/month each = $50,000/month

• Annual revenue: $600,000

• Less tools/domains: -$10,000/year

• Net profit: $590,000/year

• Time invested: 30 hours/week maintaining portfolio

• Effective hourly rate: $378/hour

• Plus exit potential: Sell 2-3 directories per year at $15K-50K each = +$30K-150K

Real revenue breakdowns:

AllGPTs (John Rush):

• Built: One evening ($10 domain)

• Month 1: 2M visitors, $0 revenue (building traffic first)

• Month 2-3: Added sponsors at $199-499 = $2,000-3,000/mo

• Added GPT boosts: $50-99 each = $1,000/mo

• Total made: $10,000 in 3 months

• Sold for: $15,000 (5-figure exit)

• ROI: 1,500x ($10 → $15K)

Nomad List (Pieter Levels):

• Year 1 (2014): Launched as spreadsheet, $5 one-time to reduce spam

• Year 2: Raised to $25, then $50, then $65 one-time

• Year 3-4: Made it $75/year recurring membership

• Current: $5.3M annual revenue

• 29,000 paying members

• Average member value: $183/year

• Costs: Minimal (solo founder, automated)

• Net margin: 90%+

John Rush portfolio (multiple directories):

• OSS Software: 500K visitors, passive income, minimal maintenance

• NextJS Starter: 73K monthly visitors, $5K/mo from affiliates

• AllGPTs: Sold for $15K

• Minibusinessideas.com: Keyword-based SEO play

• 6+ other directories each making $2K-5K/mo

• Total estimated: $30K-50K/month across portfolio

Common beginner mistakes:

• Launching in saturated niche (don't build another Product Hunt clone)

• Taking 2 weeks to build (by then trend has moved on - John Rush builds in one evening)

• Building perfect design instead of shipping (ugly directories win if they're first)

• Waiting for traffic before monetizing (add premium listings from day 1)

• Not posting aggressively everywhere (Twitter, Reddit, HN, PH all same day)

• Giving up after one directory flops (John Rush: "20 failed, 10 survived")

• Missing the trend window (custom GPTs were hot for 2 months, then cooled)

• Building for SEO instead of viral social (SEO takes 6 months, social is instant)

• Manually adding listings (use AI scraping to get to 100+ listings fast)

• Overthinking the idea (just ship it - you'll know if it works within 1 week)

Red flags this isn't for you:

• You need guaranteed income this month (this is high-risk, high-reward)

• You hate social media (Twitter/Reddit are primary distribution)

• You want to build one perfect thing (this is quantity over quality - portfolio approach)

• You're slow to execute (need to build in 1-3 days max)

• You can't handle public failure (most directories will flop publicly)

• You don't follow tech trends (can't spot opportunities early)

• You need validation before shipping (no time for user research - just launch)

• You hate selling (need to pitch influencers, sponsors, premium listings)

• You want passive income from day 1 (first directory is always hardest)

Next idea requires zero technical skills and you can earn your first dollar in 48 hours.
