Short description
Look for parts of the domain which have not changed in a long time.
Sometimes dependencies are so generic that you don't want to invest time in it and you want to buy them of the shelf: see [outsourced-generic-subdomains](Outsource generic subdomains)
But if the market is potentially disruptive, then the bought system or SaaS solution might slow you down because of lack of innovation.
Examples
The company that created slack
