Once upon a time, female entrepreneurs were hard to come by. Women were not all that interested in starting their own businesses, or so the theory went. They were seen as risk averse, lacking access to start-up capital and saddled with biological timelines that made it difficult to start a business and a family.
But in recent years, female entrepreneurs have become a powerful force in the US economy. Today, more than 9m women own businesses there, representing about 40 per cent of all enterprises in the country, according to data from the US Census Bureau.
