Most people think making money online requires coding a SaaS, starting an agency, or chasing the latest AI trend. But there’s a quieter, more evergreen opportunity: turning forgotten tech knowledge into premium digital bundles — and selling them for $100 each.

This is exactly what creators are doing with “Lost Tech Vaults,” “Forbidden Programming Archives,” and “Dead Startup Museums” — and they’re selling them to developers, tech founders, educators, and enthusiasts who are hungry for curated, hard-to-find content.

Here’s exactly how you can do it.


1️⃣ Pick a Theme That Has Cult Appeal

The key is to choose topics that are:

  • Nostalgic (developers love “lost” programming languages, old OSs, retro web tools)
  • Forbidden or hidden (secret protocols, banned techniques, obscure features)
  • Alternative histories (“What if OS/2 beat Windows?” type content)
  • Rise & Fall stories (failed startups, collapsed giants, tech scandals)

💡 Example premium products you could create:

  • The Black Book of Programming (Forbidden Code Edition) – $100
  • The Ultimate Dead Tech Archive (100+ lost OSs, languages, protocols) – $100
  • The Dead Startups Museum (100 post-mortems) – $100

2️⃣ Build Your $100 Product the Smart Way

You don’t need to create brand-new material from scratch — you just need to curate, structure, and present it better than anyone else.

Sources you can use (legally):

  • Wikipedia (historical OSs, failed tech, old protocols)
  • Archive.org (manuals, screenshots, brochures)
  • Patents and press archives (for unreleased tech)
  • Developer mailing lists (old languages, techniques)

Packaging ideas:

  • A Master PDF (100–300 pages of curated material)
  • Markdown + JSON archive (for developers to navigate easily)
  • Notion dashboard or mini website (premium experience for $100 price)

3️⃣ Sell to the Right Audience

These products aren’t for everyone — but that’s the point. Your audience is willing to pay for niche depth.

Where to sell:

  • Gumroad (great for indie creators)
  • LemonSqueezy (if you want better VAT handling)
  • Itch.io (retro/gaming crowd for old tech archives)

Where to promote:

  • Reddit (r/programming, r/obscuretech, r/compsci, r/techhistory)
  • Hacker News & Lobsters (dev-heavy discussion)
  • Indie Hackers & Product Hunt (founders, startup people)
  • Dev.to or Hashnode articles (case studies, sneak peeks)

4️⃣ Scale with Bundles & Vault Editions

Instead of selling one $100 product, combine 5–10 products into a Vault Edition for $199.

💡 Example:

  • The Lost, The Forbidden, and The Forgotten – Vault Edition ($199)
    Includes:

    • Dead Tech Archive
    • Black Book of Programming
    • Alternate Tech Timeline
    • Dead Startups Museum
    • Hacker’s Underground Study Vault

This works because once someone buys one bundle, they want the complete collection.


5️⃣ Turn It into a Long-Term Asset

You can release a new $100 bundle every 2–3 weeks and stack your catalog. Over a year:

  • 12 products × $100 = $1,200 “Vault Collection” upsell
  • 50 sales/month @ $100 = $5,000/month
  • All from curated content + digital delivery

⚡ Final Thoughts

You’re not selling PDFs — you’re selling curation, exclusivity, and depth. Developers, startup founders, and tech enthusiasts will pay $100+ for a well-organized deep dive into topics they can’t easily Google.

Start with one bundle, package it like a collector’s edition, price it at $100, and scale into a Vault Collection for $199–$299.

Your catalog can grow into an asset that makes money every month — no SaaS, no clients, just high-value digital products.
