How FounderGrowthOS compares
GTM engineering and outbound agencies differ mostly in who owns the system afterward. Some run outbound for you as a managed service, others build the data, signal, and routing layer inside your own CRM and tools and hand it over. Ask which model you are buying, what you keep if you stop paying, and how results are measured.
FounderGrowthOS uses fixed-price builds that live in the client's own tools, which suits founders who want to own the system.
