The GTM Slop Problem: Marc Sabatini on the Six Dimensions of GTM. Partner Buying, and Winning the US Market

Most B2B companies don’t fail because the product is bad.They fail because the system around it is broken.In this episode of Signal & Noise, we sit down with Marc Sabatini, Co-Founder and Chief Commercial Officer at HighSignals, to break down what Brett has been calling the GTM Slop Problem—and why so many launches stall before the market even has a chance to decide.Marc has spent 30+ years operating at the intersection of product, sales, marketing, and customer success—the exact place where strategy either turns into revenue… or quietly falls apart. This is not a theory episode.This is how go-to-market actually works—or doesn’t—in the real world.1. Why GTM breaks before the market even decidesThe biggest failure point isn’t competition.It’s internal:Misaligned teamsFuzzy narrativeNo shared systemNo clear ICPAs Marc puts it: “It’s not just slop from inexperience. It’s slop from lack of coordination.” 2. The Six Dimensions of GTM (and where they fall apart)We walk through the six dimensions every company thinks they have dialed in:Narrative (not messaging—commercial logic)ICP & targeting (focus vs. “sell to everyone”)Competitive readinessOffer & proofField enablementActivation & measurementThe takeaway:Most companies don’t have weak pieces.They have weak connections between the pieces.3. Problem Market Fit vs. Product Market Fit vs. Platform Market FitOne of the most important frameworks in the episode:Problem Market Fit → You can sell, but it’s messyProduct Market Fit → You can scalePlatform Market Fit → You can compoundMost companies get stuck in the first phase—generating revenue without ever building a system that scales.4. Why “great products win” is a mythThe uncomfortable truth:The best product rarely wins.The best go-to-market does.Even strong products fail when:Narrative is unclearProof is weakSales is improvisingCustomer success is disconnectedOr simply:Too much activity. Not enough coherence.5. Partner-Based Buying is changing everythingBuyers aren’t buying alone anymore.Agencies, SIs, cloud partners, and ecosystems are now:Influencing decisionsValidating vendorsActing as gatekeepersWhich means:You’re not just selling to the end buyer.You’re selling to the entire buying system.And that changes your proof stack completely.6. Why most companies fail entering the US marketMarc breaks down a common pattern:Too broad ICPWeak local proofMisread buyer expectationsActivity without tractionThe result:Burned time, burned budget, and burned field trust.7. The real job of GTM: building a system, not running campaignsThis is the core idea of the episode:GTM is not marketing.GTM is not sales.GTM is not a launch plan.It’s a connected commercial system.And when that system breaks:Messaging gets blamedSales gets blamedProduct gets blamedBut the real issue is lack of alignment and orchestration.There’s more product being built right now than ever before.AI has lowered the barrier to creation.But it hasn’t solved:PositioningDifferentiationCommercial executionIf anything, it’s made the problem worse.More products.More noise.More GTM slop.Founders trying to turn product into revenueCROs, CMOs, and GTM leaders fixing broken systemsAnyone launching B2B SaaS or AI productsOperators tired of “more activity” being the answerIf there’s one idea to walk away with, it’s this:A launch is not ready just because the product is ready.It’s ready when the system around it is coherent.Most companies never get there.
