Six years ago, Eos Energy CEO Joe Mastrangelo made a straightforward business decision about Pittsburgh.

"We came here just because it was cheap," he admitted at the recent AI Horizons 2025 conference.

Then came the pivot…

Pittsburgh: The Steel City. The Sports City. And now—the AI Deployed City.

$13 billion in venture-backed valuations in six months tells a remarkable story. But the real story goes deeper than capital—it's about deployment.

The question becomes how quickly will this deployed ecosystem reshape American industry and this new economy and who will want in?

The AI Horizons Summit captured this transformation in real time, bringing together the builders and deployers and many others who are making it happen. 

From sellout crowds to unicorn valuations, from factory floors to government offices, these metrics reveal a city that's moved beyond potential to proven results.

It all begins with an idea.
