AI Scales B2B Sales, But Humans Build Trust
The article argues that while AI and automation can scale three of four B2B selling relationship types, only human-to-human selling reliably builds trust and closes complex deals. It defines four selling relationship categories—machine-to-machine, machine-to-human, human-to-machine, and human-to-human—explaining the strengths and limits of each. Automated systems excel at efficient, transactional interactions (renewals, replenishment) and at shaping early impressions, but they cannot capture buyers' hidden motivations, personalities or personal risk. The author, Scott Gillum (Founder & CEO, Carbon Design), urges sales organizations to preserve and invest in human-to-human interactions as a sustainable competitive advantage in the age of AI. The piece is adapted from the upcoming book “The Hidden Buyer Journey.”
Strategic industry insight on how AI affects B2B sales and the role of CRM and human sales interactions; relevant to MarTech/CRM decision-makers but not a platform-level technical release or regulatory change.

AI Scaling the Wrong Part of Go-to-Market
The article argues that marketers and sales teams have focused AI on increasing volume—more emails, more prospecting—rather than on the preparatory work that enables human-led, relationship-driven selling. Citing industry research (Salesforce, 6sense, Gartner, ZoomInfo), the author says buyers often self-initiate and prefer human validation of AI insights; deals are commonly decided by familiarity and prior relationships. The recommended approach is to use AI to automate research, signal synthesis, data enrichment, prioritization and prediction (the “prep”), then allow humans to handle storytelling, judgment, and sending personalized outreach. The author positions 1:1 ABM and “signal-based experiences” as the highest-value GTM motion that benefits from machines doing the heavy prep while humans preserve trust and nuance.
B2B Buyers Trust AI Less Than Marketers Think
Gartner presented survey findings at the Gartner CSO & Sales Leader Conference showing that 69% of B2B buyers turn to sales representatives to validate AI‑generated insights. The survey of 645 B2B buyers (conducted August–September 2025) found buyers used an average of seven information sources during a recent purchase and that 45% used generative AI mainly to gather vendor and product information. While 67% prefer a sales‑rep‑free experience and 70% prefer fully digital self‑service buying, trust remains a concern: 51% said they are more likely to encounter misleading information from GenAI and 49% said the same about sales reps. Gartner analyst Robert Blaisdell (VP Analyst, Chief of Research, Gartner Sales practice) said sellers must shift toward validating AI outputs and supporting decision‑making at key moments. The research signals implications for sales enablement, martech content credibility, and buyer‑journey design.
Make Trust Your AI Competitive Differentiator
An opinion piece arguing that in an AI-driven market, companies—especially SMBs—should use trust as their core competitive differentiator to drive long-term profitability. The article emphasizes customer lifetime value (CLV) as the key metric, provides a simple CLV calculation example, and advises marketers to prioritize human-to-human relationships, empathy, and showing up for customers as AI accelerates pre-engagement parts of the buying process.
