A senior team that does the work.
rTheory brings technology and marketing leadership to companies that are ready to grow, with the specialists to carry the plan through.

From complexity to clarity. From clarity to results.
Sarah Butler founded rTheory to give startups and established businesses senior technology and marketing leadership, with the team to deliver it, under one roof.
Over 30 years she has built businesses in the United States and Australia, launched platforms across North America, Europe and APAC, and led marketing, product and technology work for Fortune 100 accounts, health systems, government and global enterprise. She has worked with many startups and founded her own, so she knows what a budget and a timeline feel like from the owner's chair.
Her approach is the same at a twenty-person company or a global enterprise: find what is really in the way, set the priorities, and see the work through.
“My role is to navigate complexity so leaders can focus on the decisions that drive growth.”
