It looks like quite a few companies snuck in funding rounds before the end of 2023. Boston-area companies announced $873.4 million in funding last month. That's a big increase over the previous month: By our count, Boston-area companies brought in just $280 million in November. That, however, was a low point from the $1.12 billion companies announced in October and the $1.7 billion they raised in September.
