Like many who have been active in the New York startup ecosystem over the past decade, I am optimistic about its future. The last 10 years have seen an increasing number of startup successes in New York. Shutterstock, Tumblr, AppNexus, Gilt Groupe, MongoDB, Etsy, Buddy Media, Warby Parker, Kickstarter, Gerson Lehrman, and OnDeck Capital are among them, and there are many others on the rise. Venture and angel funding are increasing, large Internet companies including Google and Facebook are growing their New York offices, and Cornell and Technion are collaborating to build a large engineering campus on Roosevelt Island.
