King Street Economics helps established businesses turn data into smarter decisions. Founded by a PhD economist with deep expertise in causal inference, forecasting, and economic analysis, we specialize in helping brick-and-mortar chains, medspas, and other growing firms make confident, data-driven choices. We focus on three key areas:

• Experimental design: want to test a new pricing model, promotion, or marketing strategy? We design structured experiments that show what works—before you roll changes out across your business.
• Observational studies: already have a wealth of business data? We dig into your historical records to find patterns and uncover what’s been driving performance, so you can double down on what’s effective.
• Forecasting & analysis: whether you’re navigating uncertain market conditions or planning your next big move, we provide clear, tailored analysis and forecasts to help you prepare for what’s ahead.
• Applied math and statistics consulting: whether you want to optimize the routes of your technicians, conduct quantitative research, or use machine learning to move your bottom line, we provide an advanced quantitative toolkit to help you optimize your firm’s decisions and processes.

Based in Alexandria, Virginia and named after its historic King Street, our firm brings academic rigor and practical insight to the real-world challenges that business owners face. If you’re looking for clear answers, not just more dashboards, reach out to us at [email protected].
