About Samuel Brahem
Samuel Brahem is a fractional GTM engineer who builds predictable B2B pipeline systems for growth-stage companies. With over a decade of experience in go-to-market strategy, outbound sales infrastructure, and revenue operations, Samuel has generated more than $100 million in pipeline across 10 or more B2B companies spanning SaaS, fintech, cybersecurity, and professional services. His approach combines deep technical expertise in CRM architecture, sales automation, and data enrichment with hands-on execution that delivers results in 30 to 60 days rather than months.
As a GTM engineer, Samuel specializes in designing and implementing the complete outbound sales infrastructure stack. This includes building multi-channel prospecting systems with tools like Apollo, Clay, and LinkedIn Sales Navigator, configuring CRM workflows in HubSpot and Salesforce for automated lead routing and pipeline tracking, deploying AI agent stacks powered by Claude and other large language models for personalized outreach at scale, and establishing the analytics dashboards and KPI frameworks that connect marketing spend to closed revenue. Every engagement starts with a diagnostic audit of the existing sales process and ends with a fully operational system the team can run independently.
What Is a GTM Engineer?
A GTM engineer is a technical go-to-market specialist who sits at the intersection of sales, marketing, and engineering. Unlike traditional sales development representatives or business development managers who focus primarily on manual outreach and relationship building, a GTM engineer designs and builds the automated infrastructure that makes outbound sales scalable and repeatable. This includes data pipeline architecture for prospect enrichment, email deliverability optimization across multiple sending domains, AI-powered personalization engines that craft relevant messages for each prospect, and the CRM integrations that ensure every touchpoint is tracked and measured. The role has emerged as B2B companies recognize that modern pipeline generation requires engineering discipline applied to the sales process, not just more headcount making cold calls.
Companies typically engage a fractional GTM engineer when they need to build or rebuild their outbound engine without committing to a full-time hire. Common triggers include transitioning from founder-led sales to a scalable outbound motion, replacing manual prospecting processes with automated multi-channel sequences, integrating AI tools like Claude into existing sales workflows for research, personalization, and follow-up automation, or fixing a broken CRM and sales tech stack that has accumulated technical debt. A fractional engagement provides senior-level expertise and execution at a fraction of the cost of building an internal team, with the added benefit of bringing cross-industry best practices from working with multiple companies simultaneously.
