Mostly known as the co-founder of Twitter, he also co-founded Square. TechCrunch reveals some of the lessons he has learned as an entrepreneur.

Dorsey revealed that both his own and his family’s experiences with entrepreneurship were inspiration for his two current startups — both of which remove friction from human communication and industry, a process Dorsey described as “getting rid of the ‘conceptual debris’.”

Dorsey has long identified with the struggles of entrepreneurs; He brought up the example of his mother, who ran a small coffee shop in St. Louis, “Starbucks came and it didn’t go so well,” he said.

Before quickly relating these stories, Dorsey said that companies need to start quicker and iterate more; “The hardest thing for any entrepreneur to do is to start.”

One of his favorite things about Square, he emphasized, is that it helps companies start, “It is amazing, you are in business right away, in terms of anyone being a retailer. The line between consumer and retailer, the counter blurs. You see this at Apple, people don’t wait in line, don’t wait behind a point of sale system, there is no counter. It takes the friction out.”
