Washington, DC. Open to new engagements.
Sam Loiterstein Founder & Operator, Product Lead, RevOps Architect, GTM as a Service, AI Workflows, and Community Builder.
I build AI expertise into real workflows and deliver GTM as a Service for teams that need product, RevOps, and go-to-market motion in one system.
Built at
Build the system before the scale.
Across products, teams, and revenue operations, growth holds when the underlying system is clear. I build the AI-assisted workflows, data structures, governance, and feedback loops that turn promising work into repeatable GTM and operations.
People set judgment and ownership. Workflow turns intent into repeatable execution. Agentic backends handle research, classification, and draft work at speed. Each layer feeds the others so the system stays accountable, understandable, and fast.
