A new ranking signals great promise for the growth of Houston’s startup network.

Houston ranks among the world’s top 50 startup cities on a new list from PitchBook, a provider of data and research about capital markets. In fact, Houston comes in at No. 50 in the ranking. But if you dig deeper into the data, Houston comes out on top in one key category.

The city earns a growth score of 63.8 out of 100 — the highest growth score of any U.S. city and the seventh highest growth score in the world. In the growth bucket, Houston sits between between Paris (64.4) and Washington, D.C. (61.7).

The PitchBook growth score reflects short-term, midterm, and long-term growth momentum for activity surrounding venture capital deals, exits, and fundraising for the past six years.

PitchBook’s highest growth score (86.5) goes to Hefei, a Chinese manufacturing hub for electric vehicles, solar panels, liquid crystal displays, home appliances, and Lenovo computers.

The overall ranking is based on a scoring system that relies on proprietary PitchBook data about private companies. The system’s growth and development scores are based on data related to deals, exits, fundraising and other factors.

Houston earns a development score of 34.1 out of 100, which puts it in 50th place globally in that regard. This score measures the size and maturity of a city’s startup network.

Topping the overall list is San Francisco, followed by New York City and Beijing. Elsewhere in Texas, Austin appears at No. 16 and Dallas at No. 36.

The ranking “helps founders, operators, and investors assess locations when deciding where to expand or invest,” says PitchBook.

“Network effects matter in venture capital: Investors get more than half of their deals through referrals, according to research led by Harvard professor Paul Gompers,” PitchBook goes on to say. “So it stands to reason that dealmakers should seek these networks out when deciding where to do business.”
