Last year was quite the year for new business startups in Central Massachusetts. Through November, 2,567 businesses in the region incorporated for the first time in 2021, according to Massachusetts Secretary of the Commonwealth data compiled by WBJ. That’s more than the 12-month totals of 2017, 2018, 2019, and 2020. Even if December’s numbers come in flat, the Central Massachusetts business community is looking at least a 10% year-over-year increase in new company starts in the last year.
