We’re obviously grateful to Lerer Ventures for investing in Vook — but we personally love the benefits and support they extend to their portfolio companies. They’re often both useful and cool. This Tuesday, they one-upped themselves by gathering members of their start-ups at Citi Field to hear from New York’s Entrepreneur-in-Chief, Mike Bloomberg.

We expected a polite overview on innovation, finance and the city’s CTO (to cover the tech angle)—but instead the Mayor delivered an impassioned, metrics driven talk focused on the qualitative benefits of New York that make the city irresistible to workers, and thus excellent for business.

Bloombgerg ticked off three key New York advantages: Education, low crime, and a cultured and environmentally forward agenda that attracts innovative young people.

Facts backed him up: New York’s crime is at a historic low—last year, with 8.4 million people, we saw only 500 murders. The city has more people enrolled in college and graduate programs than Boston has people. Finally, life expectancy in New York over the last decade has gone up three years, while remaining unchanged in the rest of America.

My suspicions are confirmed: If you can make it New York you shouldn’t try making it anywhere else, because you basically should never leave.

What really impressed us was what Bloomberg cited as the most powerful New York differentiator: Diversity and immigration. He said, “As a business, you want to be in a big city, a culturally diverse city. 40% of the people you see were born outside of the United States. They come from 48 different countries. We are country that was built by immigrants, immigrants have a work ethic and a willingness to listen to new ideas that you seem to lose as you get into place. Look at the self selection process of who immigrates. You have to give up your language, your culture, your home, your family. New York is not an easy place, New York is a tough town, and it’s competitive, and people who come here are willing to try new things.”

Since Vook moved from San Francisco to New York last year, we’re proud to count ourselves as part of the next wave of immigrants who both make and are made by this city.
