The B2B buyer’s journey has fundamentally changed. Decision-makers now conduct the vast majority of their research independently, turning to digital channels and AI-powered tools to find answers long before they ever speak to a sales representative. In this new landscape of self-education, the old marketing playbooks are failing. To win, businesses must partner with an agency that doesn’t just generate leads, but builds undeniable authority.
