GTM Engineer | I Build AI-Powered Sales, Marketing & Automation System

I help B2B SaaS companies, service & product based businesses build a go-to-market strategy from the ground up, or take an existing one that's stalled and get it working, by identifying the right ICP, making their message crystal clear, identifying the right GTM channel for outreach, and scaling with the right tools when problem/product/platform market fit has been achieved. 📌 Here's a glance at my process: Audit → ICP Alignment → Positioning → Messaging → Validation → AI-Native GTM Systems Every engagement starts with a structured audit: I score your GTM across 8 dimensions, from market focus and positioning to onboarding and leadership cadence, to find which of 5 growth blockers is constraining you: demand, conversion, delivery, retention, or expansion. From there, I align your team around whom you're really selling to, sharpen your position, message, and offer, and validate it in-market through outbound. You leave with a 90-day roadmap sequencing the fix, before I engineer AI-native systems to scale what's working. 📌 Why founders typically hire me: Pre-GTM, to bring clarity: You have a product or service but no real go-to-market system, and don't know whom to target first, how to reach them, or what to say once you do. Post-GTM, to fix what's not working: Your GTM strategy exists but has stalled, teams aren't aligned, or it can't scale with where you're headed next. 📌 Outcomes you get: Typical engagement length: 8-12 weeks, depending on where you're starting from and how much is already in place. By the end of the engagement, you'll have a working GTM system and everything you need to generate and convert the right customers: → An 8-dimension audit naming your GTM stage and biggest growth blocker → A validated ICP, built from real conversations with your best customers, not assumptions → Aligned positioning and messaging across marketing, sales, and customer success, so every team describes the product the same way → A single source of truth for your data, so decisions stop being arguments about the numbers → A working outbound system validated in market, not just planned → A 90-day roadmap with owners, dates, and what you're deliberately not doing this quarter → AI-native workflows running the repetitive work: research, enrichment, qualification, personalization → Clarity on your team's ramp, and what to systemize next as you scale → A clear-eyed view of your next growth lever: more outbound, new markets, or new offers Many clients keep me on for a lighter quarterly re-audit to catch the next blocker early. 📌 My approach to GTM engineering: → Audit before automation: I score your GTM's 8 dimensions to find the constraining growth blocker and where marketing, sales, and CS misalign, before I build anything. → Alignment before scale: Most GTM problems that look like a tooling problem are actually a single source of truth problem. Scaling a misaligned process only scales the confusion. → I build the system, not just design it: I implement it myself in Clay, your CRM, and automation tools, so what gets built gets used. → No automation without validation: Automation gets layered on only after the strategy is proven in the market, not before.
