Forrester's 'GTM Singularity': B2B's Playbook Faces an AI Reckoning

LONDON, UK – July 01, 2026 – The ground beneath the feet of every B2B marketing, sales, and product leader is shifting. A seismic event, which research and advisory firm Forrester has dubbed the “GTM Singularity,” is not on the horizon—it’s here. And it’s forcing a fundamental rewrite of decades-old go-to-market playbooks. This fall, the firm is gathering senior leaders in London for its B2B Forum EMEA 2026 to address this new reality, where the old rules of customer engagement have not just been bent, but permanently broken.

The catalyst for this disruption is the staggering speed of AI adoption. According to Forrester’s own recent data, approximately nine out of ten business buyers now use generative AI or conversational search during their purchasing process. This statistic, corroborated by multiple industry reports showing adoption rates between 89% and 94%, signals a permanent transfer of power. Buyers are now more autonomous than ever, conducting deep, independent research and forming strong preferences long before a salesperson ever enters the picture. The traditional funnel, with its predictable stages and marketing-qualified leads, is dissolving into what some are calling a “dark funnel”—a vast, untrackable space where discovery, evaluation, and shortlisting happen invisibly.

The GTM Singularity Explained

Forrester’s theme for its September conference, “Hello, GTM Singularity,” is a deliberate and stark announcement. The term “singularity” implies a point of no return, where existing models collapse and new principles emerge. As Forrester VP and Research Director Paul Ferron stated in the official announcement, “The GTM singularity is the point where AI and changing buyer behaviours permanently reshape how companies attract, win, and grow customers. Organisations that continue to use legacy marketing and sales playbooks will lose relevance.”

This isn't just about ChatGPT answering a few questions. Buyers are leveraging AI as powerful “answer engines,” moving away from traditional keyword searches on Google. They are asking complex questions, synthesizing vendor comparisons, and building business cases with AI assistance. Research from other firms confirms this, with one study finding that the pre-contact favorite vendor wins the deal 80% of the time. This self-directed journey, which now constitutes up to 75% of the buying process, makes brand visibility and trust more critical—and more difficult to achieve—than ever before.

The challenge is twofold. First, how do you influence buyers you can’t see? Second, how do you prove your value when an AI has already framed the conversation? This is the core of the “Visibility Vacuum” that Forrester plans to address in a keynote session. Legacy tactics focused on capturing leads and controlling the narrative are becoming ineffective. The new imperative is to build a brand and provide content so clear, consistent, and credible that it becomes the foundational source material for AI-driven discovery.

Rewriting the Playbook: Integration and Accountability

The collapse of the old model demands a new organizational structure. The silos separating marketing, sales, product, and customer success are no longer just inefficient; they are a liability. Forrester’s agenda points to the necessity of a unified, resilient GTM strategy that aligns teams, technologies, and customer engagement into a single, cohesive system.

One of the most critical sessions, “An Accountability Reset Is Past Due,” tackles the measurement problem head-on. In an environment where the buyer's journey is largely invisible, traditional metrics like lead volume or sales activity are misleading indicators of success. The reset calls for new performance frameworks built around shared outcomes, such as pipeline velocity, customer lifetime value, and win rates. This requires a level of cross-functional collaboration that many organizations have strived for but few have achieved. It means marketing is no longer just feeding the funnel, and sales is no longer just closing deals; both are co-owners of the entire revenue engine.

This integrated approach extends to technology and content strategy. The rise of AI search requires a shift from Search Engine Optimization (SEO) to what is becoming known as Generative Engine Optimization (GEO). This involves structuring content to directly answer likely customer questions, ensuring brand messaging is consistent everywhere, and building a library of authoritative content that AI models will favor when synthesizing answers. The convergence of brand and demand, another key conference theme, becomes essential. A strong brand builds the initial trust that gets a company included in an AI-generated shortlist, while sharp demand-focused content helps convert that preference into a sale.

Charting a Course Through the Chaos

While the GTM Singularity presents an existential threat, Forrester is positioning it as an opportunity for reinvention. The B2B Forum EMEA is designed not as a theoretical discussion but as a practical workshop for leaders on the front lines. The firm promises attendees will leave with not only research and frameworks but also peer-tested strategies and clear 90-day action plans to begin their transformation.

Underpinning this guidance are what Forrester calls the “ARC” principles for the modern B2B organization: Augmented, Resilient, and Collaborative. “Augmented” refers to the intelligent blending of human talent with AI capabilities, automating low-value tasks to free up teams for strategic thinking and complex problem-solving. “Resilient” means building flexible GTM models that can adapt continuously to market shifts. And “Collaborative” reinforces the mandate to break down internal silos and operate as one unified commercial team.

The event will also showcase real-world examples of success through its B2B Return On Integration Honours and B2B Programmes Of The Year Awards. By celebrating organizations that have already demonstrated excellence in cross-functional alignment and customer-centric innovation, Forrester aims to provide tangible proof that navigating the singularity is possible.

For B2B leaders, the message is clear: the era of predictable, linear buyer journeys is over. The challenge now is not to find a way back to the old playbook but to build a new one designed for an AI-driven world where buyer autonomy reigns supreme.
