We fix that first — and then build the system on top of My work is not about improving sales activity alone — it’s about fixing the core value drivers and mechanisms that sales performance depends Who this is for• B2B SaaS and tech companies, typically post-Seed to Series A• Founder-led sales still driving key deals• A sales team is in place — but results don’t replicate• Pipeline exists, but doesn’t convert predictably• The product is strong — but positioning and value narrative are not clearly definedGTM System Design & Conversion Architecture---In ~10 weeks, I design the GTM system your company actually needs to sell consistently. First clarity typically emerges within the first 2–3 What we do — and what you get:• Revenue diagnostics — identify what actually drives revenue, where your pipeline breaks, and where deals get stuck• Core business model — clearly defined ICP, positioning, and MVP scope• Sales packaging — structured value proposition, value ladder, and pricing logic• Sales engine design — pipeline architecture, channels, and prospecting system• Sales narrative — clear discovery, demo structure, and key messaging• Sales playbook — a practical system your team can execute, plus a clear 90-day roadmapMost importantly:A GTM system that runs beyond founder intuition — clear, teachable, and executable by your GTM Execution & Fractional Chief Sales Officer / Head of Sales---Once the system is defined, I stay involved to ensure it is implemented correctly, performs in practice, and evolves as the company In this phase, I work hands-on with the team to make the system deliver results:• Quality control & coaching — improving discovery, demos, and deal progression through real deal sparring• Processes & tools — implementation, setup, and stress-testing of the sales system• Pipeline generation — designing and running outreach and market tests that convert into real opportunities and first deals• Hiring — supporting role definition, candidate qualification, and onboarding of sales hires• Monitoring & steering — sales planning, pipeline visibility, and forecasting frameworks
