With each new employee these startups bring into the fold, the NYC tech scene becomes an increasingly dense social fabric. We hang out together, drink together, go to NYC tech events together, follow each other on Twitter and on each other's blogs. The net result is that when a new (often times consumer internet) startup is launched in the city, it's not unusual for the startup to get some great NYC grassroots "press".
For example, I remember not too long ago, Venmo caught fire on Twitter. Many of us in the NYC community know the company's co-founder, Kortina and thus were both curious and supportive of his newest venture. As Kortina's inner circle started to experiment with Venmo, suddenly announcements of people Venmo-ing money ricocheted through my twitter feed and inbox from one New Yorker to another (and therefore beyond the NYC community). At least for me, for a couple days, NYC and Twitter felt like a Venmo echo chamber. Soon thereafter, Venmo closed a seed round from NYC-based RRE Ventures, Betaworks and Lerer Media Ventures.
As far as I'm concerned, this is fantastic. SF-based companies have benefited from this effect for some time (even in pre-twitter times given the focus of more traditional media on SF-based companies). But it's taken some time for NYC to reach the critical mass to belarge enough (and tight enough) to be able to serve as a great catalyst for many up and coming NYC-based startups. All in all, this is one echo chamber I'm honored to be a part of, and hope it continues to get louder.
