San Mateo is located in San Mateo County, California, with a population of approximately 105,000. San Mateo is a prosperous city on the Peninsula between San Francisco and Silicon Valley. Home to numerous tech companies and venture capital firms, the city has one of the highest concentrations of crypto-aware professionals in California.
