• Non-adjacent spawners
• Apex Spawners
Let me explain each of them:

• Cloner spawners
• Non-adjacent spawners
• Apex Spawners

4. Adjacent Spawners
These companies start in a niche market, dominate it, and then leverage this power to expand into neighboring markets.
Starbucks is an example.
It dominated coffee chains, then launched a merchandise business, entered into supermarkets, launched a loyalty card effectively creating a financial business etc..

5. Embryonic Spawners
These are the companies that acquire high-potential startups when they are small and make them into empires.
Meta is the biggest example.
It acquired both Instagram and WhatsApp.
Today, WhatsApp is the dominant messaging app in the market, and Instagram is the dominant social network.

6. Cloner Spawners
These are the companies that successfully clone the winning products.
Microsoft is the largest example.
It's Windows was a Mac OS clone, Xbox was a PlayStation clone.
Windows 95 was a near-perfect look-alike of Mac OS 7.

8. Apex Spawners
These are the spawners that successfully deploy all the strategies above.
Amazon is the prime example.
It started in books, expanded to everything -> adjacent spawner
It bought Zappos -> embryonic spawner
It built AWS -> Non-adjacent spawner
It copied Netflix in Amazon Prime Video -> Cloner spawner

9. How to find spawners?
A very small percentage of IPOs reach a $50 billion market cap.
This means that you can't invest in a company that's larger than $5 billion for a 10-bagger and $500 million for a 100-bagger.
This is the starting point.

10. Characteristics of Spawners
There is no clear formula, but spawners share some common characteristics.

11. Let Them Run!
Once you create a portfolio of potential spawners, don't interrupt the process unless the secular decline is obvious.
Companies don't become 10-baggers overnight.
It's a bumpy road, set it and forget it!
