If you’re still marketing and selling to the buyer you knew 10 years ago, you’re aiming at someone who’s already gone. Today’s decision-maker researches independently and makes most of the call before your firm ever hears from them, so by the time you’re invited to pursue, the shortlist is already set. Around 80% of the buying journey is complete before a buyer ever reaches out to a vendor (Gartner 2024).

This piece walks through who that buyer actually is now, when and how they decide, what they weigh, and why some of the business development moves you’ve always trusted have quietly stopped working.

• Around 80% of the buying decision is made before a firm is contacted (Gartner 2024).
• Millennials now make up 73% of B2B buyers and 44% of final decision-makers (LinkedIn 2025).
• Buyers weigh values, thinking, and peer proof before they weigh credentials and cost.
• Cold outreach, gated content, and credentials-first proposals are losing effectiveness.
• Firms win by being present and trusted during the anonymous research phase, before the pursuit begins.

Earlier than most firms think. 80% of the B2B buying journey is complete before a buyer reaches out to any vendor (Gartner 2024), and 61 % is complete before first contact (6sense 2025).

Forrester puts it plainly:

B2B buying today is a process of confirmation, not selection. The buyer already knows who they want to work with. The pursuit, the proposal, and the interview are the final stretch of a decision largely made without the firm’s participation.

That decision is made during the anonymous research phase: peer conversations, private communities, web research, podcasts, and now AI tools. This is where AEC shortlists are built. Firms not visible during the research phase aren’t losing pursuits; they never make the list!

The shift is mechanical as well as behavioral, since AI-assisted tools now handle early filtering and proposal scoring, and firms leaning on recycled, boilerplate content get screened out before anyone reviews the submission.

The criteria that carry the weight of the decision have changed, and they are formed during the research phase, before any pursuit begins. Drawing on the Value-Based Decision Criteria developed by Sarah Kinard and confirmed by the SMPS Foundation Emerging Trends 2026 research, the criteria that now lead are:

Technical competence, past performance, and cost still matter, but later, as confirmation of a decision already driven by criteria most firms never explicitly addressed. As the Triune Brain model makes clear, roughly 90% of the decision is made by the emotional and instinctive brain. The part where credentials and logic live rationalizes it afterward.

They were designed for a different buyer and a different buying process. They are not dead, but their effectiveness has dropped, and firms blaming lost pursuits on bad luck may be missing a structural mismatch. The moves losing power include:

• Cold outreach and relationship-first prospecting. 73 percent of buyers avoid suppliers who send irrelevant outreach, and 61 percent prefer a rep-free experience (Gartner 2024). The harder a firm pushes, the more resistance it creates.
• Credentials-first proposals. These appeal to the part of the brain that makes the final decision. The buyer reads the proposal to confirm a verdict already formed, not to decide whether to trust the firm.
• The trusted advisor approach as the primary strategy. Deep personal relationships no longer guarantee shortlist inclusion, and the approach is negatively correlated with performance in AEC (Hinge Research Institute).
• Gated content as the main way to capture leads. Buyers expect value upfront and refuse the form, so the content never reaches them when it matters most.
• Static, recycled collateral. Algorithms detect boilerplate and compare standardized language across submittals.
• Event attendance as relationship maintenance. Buyers attend to hear experts speak as part of evaluation, not to build new vendor relationships over casual conversation.
