Last week, I was at Atlanta Tech Village delivering short opening remarks for a large AgeTech Connect conference. AgeTech, as the name suggests, is a fast-growing sector focused on aging and the realities of our rapidly aging population.

As both a conference theme and an industry, AgeTech is one of those ideas that feels obvious now but has actually been building quietly for years. It’s a perfect example of what I love most about startup communities: there’s always something new, there’s always a hot trend emerging, and there are always passionate people working to invent the future.

After the conference, I had the chance to sit down with an economic development professional to discuss tech, startups, and startup ecosystems. As we spoke, with the AgeTech conference happening just down the hall, it prompted me to reflect on many other trends and communities we’ve seen come through these walls over the years.

When we first opened Atlanta Tech Village more than a decade ago, Bitcoin was just starting to gain traction among early-adopter tech circles, far from mainstream acceptance. For years afterward, we hosted numerous Bitcoin and blockchain companies, along with their events and conferences. That industry has since matured dramatically, riding multiple boom-and-bust cycles of its own.

The point isn’t to single out one or two trends like AgeTech or blockchain. Rather, it’s that startup communities, by their very nature, sit at the front edge of new technologies and nascent trends.

So if you’re an entrepreneur or aspiring founder looking for ideas, co-founders, or the next big opportunity, my recommendation is simple: spend time at your local startup hubs. Sign up for their events, subscribe to their newsletters, and follow them on social media. You’ll get a constant stream of both emerging and established ideas.

It’s one of the best ways to stay current on new trends and discover the next great market before it becomes obvious to everyone else.
