Why Greene Street
Greene Street Co. was built on a simple premise: most people making big financial decisions — buying a car, analyzing a market, growing a business — are doing it without anyone truly in their corner. We change that. No commission conflicts. No upsells. Just clear-eyed counsel from someone who's worked inside these industries.
About
Greene Street Co. is a Los Angeles-based sole proprietorship offering a focused set of advisory services to individuals and small businesses. The firm was founded by David Greene, whose background spans the automotive industry — including time at Cars.com — along with data analysis and business consulting.
The name comes from a simple idea: a street where things get done. Greene Street Co. is deliberately lean — no overhead, no account managers, no markup for a brand name. What you get is direct access to someone who has worked inside the industries where you need help.
The practice focuses on three areas: helping car buyers navigate dealerships without getting taken advantage of, supplying clean economic data to analysts and researchers who don't want to spend hours cleaning government spreadsheets, and providing practical advisory support to small businesses on strategy and operations.
This is a boutique practice by design. Greene Street Co. works with a small number of clients at a time to ensure every engagement gets real attention.
Services
Three focused service lines. Each one built around a real information gap — where having the right person in your corner changes the outcome.
Buying a car is one of the largest financial decisions most people make — and most dealerships are set up to extract maximum value from buyers who don't know the playbook. I do.
I accompany you through the entire process: vehicle selection, dealer negotiation, financing review, and final paperwork. You stay in control. I handle the pressure.
Government economic data is publicly available — but raw, inconsistently formatted, and time-consuming to clean. I source, standardize, and deliver it as analysis-ready spreadsheets.
Ideal for analysts, researchers, consultants, and small businesses that need reliable economic data without the prep work.
Practical strategy and operations consulting for small businesses. No frameworks for the sake of frameworks — just direct thinking on the problem in front of you.
Well suited for founders and operators who want an outside perspective from someone who can engage with real details, not just high-level advice.
