For years, many growth professionals relied on the T-shaped marketer model. It seemed logical: develop deep expertise in a primary channel (the vertical line) while staying informed about other marketing areas (the horizontal line). Thought leaders like Brian Balfour and teams at Buffer championed this approach. Stefan at CXL also explained how it blends specialist and generalist skills.

Why The T-Shaped Model Is Evolving
Lately, three key changes are redefining the T-shaped role:
-
AI And Automation. Tools now create copy, design assets and prototypes. Jobs once held by specialists can be done by almost anyone with the right software.
-
Unpredictable Shifts. Rapid changes in the market ask for marketers who are ready to pivot. A single area of expertise is no longer enough.
-
Speed And Autonomy. Growth teams need to launch experiments fast. Great marketers today often juggle multiple channels instead of relying on one specialist.
Some, like Josh Lachkovic (read more here), argue that the T-shaped profile is ceding ground to the ‘growth artisan’—a marketer who builds entire growth systems, thinks like a founder and adapts to new data constantly. Daphne Tideman makes a similar case, advising startups to hire generalists who understand acquisition, conversion, and retention before investing in specialists. For a deeper dive into the emerging alternative, see Full Stack Marketers – The Antidote to Stagnation and why AI-powered generalists are replacing marketing specialists.
AI Search Is Collapsing The Channel Silos The T Was Built For
The T-shaped model assumed channels produced separable results. Your SEO traffic was your SEO traffic. Your social engagement was your social engagement. You could trace which lever moved which number. AI search breaks that assumption.
When a buyer asks ChatGPT, Claude, Perplexity or Gemini about your category, the answer is assembled from many places at once: your reviews, your LinkedIn posts, your community presence, your PR coverage, your blog, and the training data underneath it all. As Alex Birkett of Omniscient Digital puts it: “One output. Many inputs.”
That changes what the role is. Birkett argues AI search visibility “is, in many ways, an emergent property of everything your organization does and also everything your competitors and customers do.” No single channel delivers the full signal. The channels now feed a single mouth, which means deep expertise in any one of them is necessary but no longer sufficient.
From Channel Expertise To Portfolio Management
The marketer this era rewards isn’t deeper in one channel. They’re wider across all of them, with the judgement to know where investment compounds and where it dissipates. Birkett frames the core skill as allocation rather than optimisation:
“The hard question isn’t ‘how do we optimize our blog for AI search.’ It’s ‘given limited budget, how do we allocate across SEO, LinkedIn content, community management, creator partnerships, digital PR, review generation, and original research to maximize our composite AI visibility?’ This is portfolio management, not channel management.”
Three traits define the marketer who owns this:
-
Customer-obsessed, not channel-obsessed. They start with how buyers discover, evaluate and choose, then work backward to which channels and content types influence that journey in AI-mediated environments.
-
Oriented toward perception and visibility metrics. Not just traffic, conversions or even citation share, but the ability to read patterns across many inputs (brand mention frequency, sentiment, accuracy of outputs) and prioritise the biggest levers against the business goal.
-
Cross-functional allocation as a core competency. Deciding how to spread finite budget across SEO, social, community, PR, creators and original research. This is the same logic behind a channel portfolio strategy, now applied to composite AI visibility rather than acquisition channels in isolation.
If that sounds like a return to an older archetype, it is. The role looks less like a channel specialist and more like an integrated marketer (or, plainly, a brand marketer) equipped to orchestrate across functions. For the AI-native version of this generalist, see the essential role of marketing generalists in modern teams.
Shifting To A New Growth Mindset
The most effective marketers focus on first principles. They form hypotheses, set clear metrics, and align each experiment to a wider growth strategy. Rather than fixating on specific tools or channels, they track how every outcome impacts the bigger picture. This blend of data-savvy thinking and creative problem-solving is the new hallmark of an impactful marketer.
