New research suggests when it comes to startups, past performance does indeed predict future results:
Serial entrepreneurs were far more effective than novices, with 98% higher sales, on average ($54,800 per month versus $24,600 per month). They were also 49% more productive, once capital and labor were considered. This difference in the success of serial and novice entrepreneurs also proved consistent across firm sizes. Among the largest firms in the sample, for instance, those run by novice entrepreneurs averaged $943,000 in sales, while those run by serial entrepreneurs averaged $1.99 million in sales—roughly twice as much.
