Tyos installs the GTM operating system founders use to scale revenue — and funds use to bring more structure and visibility across the portfolio.
Segmentation. Narrative. Focus. Execution.
Built as a system. Run with discipline.
Etienne Viellard has spent 27 years helping B2B technology companies build and scale their go-to-market engines — from leading global campaigns at Oracle, to senior marketing roles at Salesforce and Hyperion, to supporting Neolane’s international growth ahead of its acquisition by Adobe.
For the past 12 years, he has worked with more than 100 B2B scale-ups across Europe, the U.S., and APAC — helping founders sharpen their positioning, define their category, support major fundraises, and structure U.S. expansion.
Tyos brings that experience together in a practical GTM operating system for founders and funds seeking stronger commercial foundations, clearer execution, and more predictable growth.
We install the system, enforce focus, and drive execution.
Clarity in strategy. Discipline in motion. Predictable growth.
