Some interesting funding news to report. First, we’re close to finding out whether Massachusetts is home to one of the coolest breakthrough companies of the clean-energy era or one of its biggest busts. The BBJ has the latest on Devens-based Commonwealth Fusion system, which just raised another $863 million, bringing its total capital raised to nearly $3 billion … Nvidia and Google obviously have confidence in Commonwealth Fusion’s future. But I still have my nervous too-good-to-be-true doubts, based on having seen (and written about) way too many clean-energy busts over the years. …  I’ve previously posted about Commonwealth Fusion here.

Meanwhile, Andover-based Reframe Systems may not be the coolest startup, but it’s definitely a cool and fascinating housing startup. B&T reports Reframe Systems has raised $20 million to “build a series of ‘microfactories’ to crank out modular buildings like ADUs and three-deckers.”  … Sounds great. But it all depends on how local towns and cities react. They haven’t exactly embraced modular construction in the past, unfortunately.  … One of the firm’s triple-decker products looks pretty damn good to me.
