21 Boston Companies to Watch in 2021

We’re well into 2021, and Boston tech has proven once again that it’s a magnet for innovation and investment.

After capping off a year that included 10 companies collectively raising close to $3 billion, Boston tech is off to a hot start with five companies raising more than $1.1 billion — in March alone. 

It’s both impressive and indicative of the overall health of our port-side tech hub, a growing community that blends startup graduates from Cambridge and MIT incubators with tech staples like Amazon, Salesforce and Klaviyo.  

As 2021 continues to unfold, Built In Boston rounded up 21 companies positioned for another strong year, some of which have already tallied key wins with product releases, large partnerships and millions in funding.
