Jon Miller’s 2026 B2B Forecast: AI Will Force a Complete Go-to-Market Overhaul

Each year, B2B marketing leaders analyze predictions from Jon Miller, co-founder of Marketo and a key architect of modern marketing automation. His 2026 forecast provides a clear-eyed assessment of where the industry is heading. The core message is that artificial intelligence is fundamentally rewiring the go-to-market engine.

In a detailed post on Chiefmartec, Miller explains how AI is becoming a member of the buying committee, forcing a long-overdue overhaul of tech stacks, and making human judgment more valuable than ever. This is a realistic view of the changes already underway.

Marketing to AI Agents Is Now a Requirement

Marketers must now create content for AI agents, not just humans. When buyers use tools like ChatGPT or Perplexity for initial vendor research, they deploy AI agents to gather information. A bot scraping for data does not care about your website’s user experience.

This reality requires a two-track content architecture. One path is for humans and focuses on brand story, emotional connection, and usability. The other is for AI agents and is designed for clean data extraction. This includes headless content management systems, pricing APIs, and structured knowledge bases that can answer specific questions without friction. Product marketing teams will soon measure success based on how an AI describes their company versus the competition.

While some marketers focus on “Answer Engine Optimization” (AEO) with special markup and structured FAQs, Miller suggests these are temporary tactics. He expects AI will eventually become smart enough to parse human-centric content, making technical workarounds unnecessary. The permanent change will be the infrastructure that serves clean data on demand.

AI agents are now the primary researchers on the buying committee. They handle objective criteria like capabilities and compliance, which compresses the research phase. Humans still sign the contracts, so the marketer’s job is to feed machines structured information while building the relationships that close deals.

AI Replaces Brittle Rules in Your Tech Stack

For years, marketing automation has operated on rigid, rules-based logic. For example, if a prospect’s title contains “VP,” add 10 points. If they open an email, wait two days and send another. These systems are fragile and cannot adapt to the complexity of a non-linear B2B purchase.

Miller predicts that reasoning AI will replace this rules-based logic. Marketers will provide strategic guardrails, goals, and context. The AI will then determine the best path for each buyer. This will help deliver on the promise of one-to-one personalization through intelligent sequencing rather than dynamic content.

He calls this approach “AI Playlists.” Instead of selecting a single “next-best-action,” the AI curates a sequence of actions and dynamically adjusts based on real-time engagement signals. The system learns and adapts, combining offers, channels, content, and timing from a pre-approved library to create billions of unique journeys without requiring millions of custom assets.

This shift will be gradual. Existing platforms like Marketo or HubSpot will integrate AI-assisted features. New, AI-native platforms will build the bridge to a more agent-driven future, offering familiar user interfaces built on an architecture for autonomous operations. The role of marketing operations will also change. It will become a more strategic function Miller calls “context engineering,” which involves teaching the AI operational knowledge like campaign naming conventions, segmentation logic, and lead routing rules. This makes your AI useful and captures institutional knowledge that often disappears when an employee leaves.

Human Judgment Becomes Your Competitive Edge

With AI making content creation nearly free, digital channels are filling with low-quality, AI-generated material. This content is grammatically correct and well-formatted but has no original thought. As the volume of this content increases, buyers will rely on filters to manage the information.

Miller argues this will force a change in communication strategy. When every sales development representative can generate thousands of personalized emails a day, email marketing shifts from an owned to an earned channel. Inbox attention must be earned through relevance and value. AI inbox gatekeepers will summarize, bundle, and filter messages before a human sees them. Sending a generic weekly newsletter is actively training the recipient’s AI to ignore you.

The solution to AI-generated content is human-generated value. Miller points to three attributes that will define meaningful communication.

• Taste is the editorial sensibility and storytelling instinct to know what is worthwhile.
• Trust is the relationship you build over time through founder brands and subject matter experts.
• Accountability is the willingness to stake your professional reputation on the information you share.

This dynamic also changes the value of intent data. Public signals from job changes or G2 activity are becoming commodities. The advantage shifts to proprietary signals from your first-party data. How prospects engage with your content, product tours, and sales team provides an informational edge no competitor can buy. The new advantage in B2B marketing comes from combining these proprietary signals to pinpoint who to contact and precisely when.

The Mandate for B2B Leaders: Adapt or Be Displaced

Miller notes the massive uncertainty facing the global economy, amplified by the disruptive force of AI. The risk of job displacement for entry-level roles is significant. Companies are maintaining productivity without backfilling junior positions, which removes the entry point for the next generation of talent.

The path forward is to build resilience through efficiency, enable people to work alongside AI, and rethink team structures to favor adaptability over hyper-specialization. The objective is to automate complex tactical work, which frees people to focus on strategy, creativity, and building genuine connections.

Success in 2026 will come from navigating a landscape that is constantly shifting. For B2B leaders, the work is clear. Build a solid data foundation, invest in your people’s judgment, and prepare for a future where the scarcest resource is no longer content, but trust.
