Key Takeaways
-
Generative AI is directly shaping B2B supplier evaluation: 20% of decision-makers already use it to research vendors, with more following.
-
Buyer journeys are increasingly AI-mediated and remote: High-value B2B transactions over $500K are now common through digital channels.
-
AI systems influence perception and brand trust: How AI tools represent your brand materially affects the buyer’s judgment.
-
Content must be optimized for AI as well as human relevance: Structured, clear, and differentiating content increases the chance of discoverability.

Brand strategy must now include AI as a communication layer: Search, discovery, and evaluation are increasingly conducted through AI.
A quiet revolution is underway in how business buyers behave. The rise of generative AI is enhancing operational efficiency for businesses and is also transforming how buyers discover, evaluate, and engage with them. Across industries and geographies, decision-makers are incorporating AI into their buying processes in ways that directly alter the role of marketing and sales.
AI Tools Are Reshaping the Early Buyer Journey
A recent McKinsey B2B Pulse report underscores this shift: 20% of decision-makers, categorized as “Innovators,” are already using tools like generative AI to research suppliers and inform shortlisting decisions. Another 23% are in the process of exploring such applications.
These buyers are relying on AI at one of the most critical steps in the procurement process — vendor qualification. This has two implications. First, B2B marketers are no longer speaking directly to buyers alone; they are speaking to the AI systems buyers consult. Second, much of the first-level evaluation now occurs before any contact is made with the sales team.
If positioning is unclear, differentiation is vague, or content lacks depth and structure, it risks being summarized incorrectly or ignored entirely by AI systems. Vendors that cannot make their case in ways that align with both machine parsing and human reasoning are at a strategic disadvantage.
Digital Maturity is Enabling High-Value, Low-Touch Transactions
The McKinsey research indicates that the rise of AI is coinciding with a broader normalization of remote and digital-first transactions. Buyers now engage across an average of 10 interaction channels, up from five in 2016. Among the “Seeker” archetype, 69% are comfortable transacting deals worth over $500,000 through remote or self-service channels. Even among “Adapters,” a more traditional group, nearly 20% express the same comfort.
E-commerce, long seen as a consumer domain, is now central to B2B revenue. For companies that have invested in online sales infrastructure, 34% of revenue now comes through e-commerce, making it the top revenue-generating channel for those firms. Furthermore, one-third of B2B organizations have increased their e-commerce investments by over 11% in the past year.
Marketing must now function as the lead engine for digital revenue generation. Sales, too, must be restructured to support asynchronous conversations, accelerated decision-making, and high-value transactions conducted with limited or no physical interaction.
AI is Changing Buyer Perception
Research from the MIT Media Lab reveals a deeper insight into how users interact with AI: the way an AI system is introduced affects how people perceive its trustworthiness, empathy, and performance. In experiments, users who were primed to believe that an AI had helpful motives rated it as more competent and reliable than those who received no such framing.
This is not simply a technical or UX concern. It is a branding issue. Whether through AI-powered search, chatbots, or third-party LLMs, companies are increasingly represented not by humans, but by the responses machines generate on their behalf. If an AI assistant misrepresents a brand’s value proposition, or if it appears unhelpful or mechanical, trust in the brand erodes before any human contact occurs.
Brands that invest in structuring their content for clarity, accuracy, and discoverability—especially in AI contexts—stand a better chance of being understood and trusted. Those that fail to do so will be marginalized in AI-driven discovery.
Rising Expectations and the Personalization Gap
Forbes’ research in 2024 points to an emerging contradiction in consumer and buyer behavior. On one hand, 67% of consumers expect companies to personalize their interactions. On the other, only 26% believe AI delivers effective personalization, and fewer still believe it improves their overall experience.
This misalignment creates brand risk. If AI-driven personalization fails to meet expectations, or feels misaligned with user needs, it may be perceived as irrelevant or intrusive. Worse, it can create friction where customers expect convenience.
For enterprise marketing teams, the answer is not to withdraw from personalization efforts but to apply greater discipline. That means grounding personalization in consented, first-party data; designing journeys that allow for intelligent handoffs between AI and human touchpoints; and clearly articulating the value of AI-driven engagement to the buyer.
The AI Layer in B2B Brand Strategy
As AI continues to act as an interpretive layer between the buyer and the brand, companies must assume that discovery, evaluation, and even preference formation are now mediated. Buyers are influenced not only by what companies say but by what AI systems reflect back to them.,
For B2B leaders, this presents an inflection point. The traditional marketing funnel has already been disrupted by content saturation and channel proliferation. AI now adds a layer of interpretation and prioritization that marketing and sales strategies must be designed around.
With consumer and B2B buyer behavior evolving in response to the increased adoption of AI, brand owners must keep pace to ensure they remain relevant and enjoy buyer trust in this changed world.
