Independent. Rigorous. Trusted.
An independent consultancy with one of the most experienced economic impact teams in the industry.
Built by Economists, for Impact
Founded in 2024, Zenith was created with a singular focus: the most rigorous, defensible, and professionally designed impact studies in the market. We are fully independent: we have no financial interest in the outcomes of our research, which is why our clients trust us and why our findings hold up to public scrutiny.
Today, our team has contributed to 100+ studies spanning ports, airports, data centers, festivals, pension systems, and state agencies. Our work has been cited in Billboard, NBC, ABC News, and by state comptroller offices, a testament to the credibility and reliability of our research.
California-certified Small Business. Home to two of the roughly three dozen IMPLAN Certified Economists in the world.
