Entrepreneurship networks can create industries. 

If successful entrepreneurs reinvest their success through angel investment, serial entrepreneurship, or mentorship, or because their employees start their own companies, they have a multiplier effect on the economy. 

This social network map tells the story of how the connections between Cape Town and Stellenbosch's tech entrepreneurs made the sector as we know it today.

FOUR CONNECTION TYPES

Previous research by Endeavor Insight has found that entrepreneurs influence a sector's growth in four important ways:

1. By making angel investments in other entrepreneurs;
2. By mentoring other entrepreneurs;
3. By becoming serial entrepreneurs, and
4. Through their former employees, who start their own companies.
