Brian David Hall
Growth / Hacking


I help companies test and personalize their sites so they can grow their business while making the Internet a better place.

A/B Testing

As a product manager and engineer I've worked with dozens of clients, run hundreds of tests, and overseen millions of dollars worth of optimizations.


It takes usability training, audience insights and considerable jQuery chops to instrument a site and launch p13n campaigns; I can help.


Full Stack Web Dev

I build elegant, modular apps that Just Work so Shopify merchants can customize their shops and delight their customers.

Data Analysis

Whether it's Google Analytics sessions or chance encounters on reddit, no byte will be left unturned.
