I’ve just wrapped up a visit of three cities — Boston, New York and Washington, D.C. — and saw significant startup action happening in each one of those cities.

In New York, several people told me the NY startup community is in fact now as vibrant as ever. Some 500 people joined us at an after-hours party we co-sponsored in Manhattan after the New York Tech Meetup. Even in smaller cities, such as Boston and Washington, we had about 100 people show up to events we’d arranged just days before.

These were informal meetings, but in Boston and Washington, we invited entrepreneurs several entrepreneurs to give three-minute pitches, which was the funnest part (nice write-up of the Boston companies here in BostInnovation). At one point in Washington, the mic went dead, but folks didn’t mind, and kept getting up and shouting out their pitches over the crowd’s noise and background TVs. Below are videos we taped of a few entrepreneurs after our cocktails in Washington: Kevin Dewalt (who is working on a bioinformatics startup, focused on the cloud), Scott Brown (co-founder of TapMetrics, acquired last month by Millennial), and Frank Gruber (working on a new umbrella of startups).

We’ll be back on the road over the next few months, to continue our search for more entrepreneurs intent on changing the world with their technologies. As announced earlier, we’re bringing them to DEMO on┬áSept. 13-15, when the event will be held in Silicon Valley for the first time ever. It’s going to one of the best shows yet. We’ll be announcing more plans around that shortly. For now, though, you should make sure to lock in on the low price of $975, to assure your spot. That’s about a third of the usual price. DEMO has the highest standards I’ve seen at any event, from the coaching companies get, the networking events they’re invited to, press release help, and much more. The latest and greatest companies and technologies around will be launching there. It will be chock full of networking opportunities, too.
