A letter from our CEO, to you

Georgina Campbell FlatterChief Executive Officer

The opportunity of a lifetime

Here’s what we believe. We are living through the most significant redesign of industrial systems since the Industrial Revolution—how we generate energy, build cities, make materials, move goods, and grow food. All of it, all at once.

Look at energy. Demand is climbing fast, with electrification, manufacturing, and the explosion of data centers and AI all pulling on the grid. At the same moment, we have a once-in-a-century opening to meet that demand with clean power. The capital is already moving: global investment in clean energy is at record highs, trillions of dollars a year. More energy AND fewer emissions.

Look at how we make things. The world is building and manufacturing more than ever, and that expansion is our chance to design out emissions, toxicity, and microplastics from the start, rather than cleaning them up later. Build more AND build cleaner.

And look at work itself. The jobs landscape is being redrawn in real time, and here’s what most people miss: new jobs come overwhelmingly from new companies. Decade after decade, it’s young firms that create most of the net new jobs. If you care about jobs, you care about new businesses. Build more AND build cleaner AND put more people to work.

Some see all this change as a crisis to manage. We see the opportunity of a lifetime, because we refuse the old trade-off: prosperity AND a thriving planet, neither at the expense of the other. We call it the Power of AND.

Built by entrepreneurs

That future gets built by entrepreneurs—bold, gritty, willing to challenge the status quo. They’re how a breakthrough becomes something the world can buy, whether cheaper energy storage, cleaner steel, carbon pulled back out of the air, or any number of other innovations.

But 15 years have taught us this: strong companies rarely fail because the science was wrong. They fail in the hardest stretch, from first prototype to first customer, because they run out of time, money, or believers. That stretch isn’t a test of the founder alone; it’s a test of the community around them. Where a company builds matters as much as what it builds.

That’s why Greentown exists. In Boston, in the middle of the world’s densest innovation ecosystem, and in Houston, where the world’s energy industry is reinventing itself, founders find the labs, the talent, the capital, and the first customers to move faster. Industry partners find their front door to what’s next. And everyone finds a community that leans in.

Come build with us

Our vision is simple to say and worth a lifetime of work: more energy, fewer emissions, and good jobs—built by entrepreneurs, backed by all of us.

So come find us. If you’re a founder, come build here—this community was made for you. And if you’re ready to get behind the builders: tour the labs, pilot a technology, mentor, invest, donate. This is a decisive decade, and it will go faster, and be more fun, with you in it.
