How startup ecosystems reshape cities

A startup changes a city when it hires, and only to the extent of that hiring. The Bureau of Labor Statistics publishes metro payrolls. A funding announcement is not one of those series. No headcount is read out here.

The jobs show up first as households looking for a place to live along the commute. They show up as a commercial lease only when the firm takes space. A software firm can add people without adding much floor area. A laboratory firm cannot, because the bench, the power and the ventilation are the work. An empty office and an empty laboratory are not one vacancy.

In cities where technology employment is already large, the base payroll is often a company that is no longer a startup. A new firm beside it can matter to formation and still be a small share of the jobs. Treating every financed company as tomorrow’s office tenant overstates the commercial market and understates the housing one.

Private capital can be raised under the SEC’s venture-capital rules and spent in a different city from the fund’s office. A United States company is often formed in Delaware. That filing creates a legal person. The workplace and the bedroom can sit somewhere else. The three are allowed to be in different places.
