Competitor marketplace cross-posting hijack
Build functionality that lets your users automatically repost their listings to a larger incumbent platform, funneling that platform's traffic back to you.
Why this can grow a startup
Airbnb reverse-engineered a way for hosts to replicate their listings onto Craigslist, which had 42 million monthly users at the time. Craigslist users who clicked on these listings were redirected to Airbnb, converting them into new users. Guest arrivals grew from 20,000 to 3 million per year between 2009 and 2012. The hack worked because Airbnb offered a superior user experience once visitors arrived.

When to use it
Use this when Communities, Partnerships is relevant to 0-100, 100-1K and you can run a bounded test with a free budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
Founder checklist
- Read targetinternet.com and identify what is directly supported.
- Choose one channel context: Communities, Partnerships.
