Dan Norris is a serial entrepreneur, 4X best-selling author and international speaker.
In 2013 he was 2 weeks away from unemployment after 8 straight years of business failure. In the next week, without any funding, he launched a WordPress support service called WP Curve, providing ongoing small fixes for a monthly fee.
Within 2 years, it was a $1m business with over 40 developers in 7 countries and thousands of clients. He sold the business to GoDaddy in 2016.
Instead of messing around trying to validate ideas or debating things with his entrepreneurial friends during this process, he just launched. Then he made decisions based on real information from real customers to build the business. He now helps other entrepreneurs do the same thing via his books and private mastermind.
