Technological knowledge, i.e. knowledge of computing and informatics, has never been more important for an entrepreneur than it is today. Today, for modern start-up entrepreneurship, business and management skills that enable mastering strategies and the business environment are far from sufficient. An entrepreneur must be innovative and creative, have a knack for dealing with employees, and cannot defend himself even with knowledge of corporate finance. To this must now be added appropriate technical knowledge such as knowledge of a programming language, mastery of website optimization and web programming, knowledge of creating a website skeleton (wireframe),... Which other necessary skills for modern start-up entrepreneurship are still important, but you are faithful in continuation.
