Since blogging about my TAM Onion framework in 2019, I’ve had requests to provide examples of the TAM Onion approach by successful companies such as AirBNB, Google, or LinkedIn, even if done retrospectively.  Following is a table of some potential examples.  These are imagined retrospectively, so cannot be assumed to be the actual strategy in these companies’ early days.  However, hopefully, they help illustrate the application of the TAM Onion.
