Has AI made IT the most important alignment for B2B marketers?.

Sales alignment used to be B2B marketing’s biggest problem. AI has opened up another front.

As artificial intelligence moves from experimentation into core infrastructure, the limiting factor for B2B marketing is no longer ideas, channels or even budgets. It’s whether marketing is aligned with the teams that own data, platforms and governance: IT.

That doesn’t mean sales alignment no longer matters. It does. But from what I’ve seen at the AWS Summit and the B2B Marketing Leaders Forum this month, many marketers are underestimating how decisively AI shifts the balance of execution power and how exposed marketing becomes without deep alignment to IT.

As AWS’ Werner Vogels put it at the recent AWS Summit “we’re starting to solve problems we once thought were unsolvable. The limiting factor isn’t technology, it’s our imagination”. Marketers have the imagination, but do they have the skills to deliver AI transformation.

We’ve been here before. Gartner’s research has consistently shown that MarTech implementations fail to deliver their promised value (Gartner Marketing Technology Survey 2025 - Only 49% of Martech capabilities are being used). Not because the tools don’t work, but because the foundations underneath them don’t.

AI accelerates this reality.

AI doesn’t live in campaign plans or brand frameworks. It lives in:

• Data architecture

• Cloud platforms and system integrations

• Security, governance and access control

• Decisions about which systems talk to each other, and how

In most organisations, this is IT’s domain. If marketing isn’t deeply aligned here, it risks becoming the function with the biggest ambitions and the least ability to execute them.

There’s no shortage of excitement about what AI could do for B2B marketing:

• Faster content production

• More precise personalisation

• Better lead scoring and forecasting

• Continuous experimentation at scale

All of that is real. But AI is also unforgiving. It amplifies what already exists. Fragmented data becomes more visible. Poor integration becomes more painful. Weak governance becomes a hard stop. And the scramble to keep up with the latest model or platform magnifies the procurement headache that has persisted since mid-naughties SAAS.

Marketing is often downstream of these decisions, trying to “use” AI on top of foundations it never helped design.

From IT’s perspective, marketing’s AI enthusiasm can look like another vendor, another integration risk, another governance exception. From marketing’s side, IT can feel slow, conservative or obstructive (something to work around rather than work with).

Both perspectives are understandable. Both miss the point.

Marketing brings the commercial intent, customer insight and growth use cases. IT brings the architecture, scale and risk management that make those use cases real. AI only delivers value when those two worlds are designed together.

This is where B2B marketing leadership needs to evolve.

The next generation of effective marketing leaders won’t be defined only by channel expertise or creative instinct. They’ll be defined by their ability to operate across systems.

That means developing:

• Technical fluency (not coding, but comprehension)

• Architectural thinking

• Credibility with IT peers

• Governance awareness

Marketers don’t need to become technologists, but they do need to evolve into credible partners in how organisational capability is built.

Here’s the uncomfortable truth: AI will not lift all B2B marketing teams equally.

It will widen the gap between:

• Organisations with strong data and platform foundations and those without

• Teams embedded in technology decisions and those bolted on after the fact

• Marketers who can influence infrastructure choices and those who wait for access

In that world, creativity and strategy still matter. But infrastructure increasingly decides what’s possible. Done well, tighter alignment with IT doesn’t constrain marketing ambition. It expands it. But only if marketing is involved upstream, where platforms, operating models and rules are set.

The boundaries between marketing, data and technology are collapsing. Growth is no longer delivered by campaigns alone. It’s delivered by systems that learn.

That demands a different kind of marketing leadership. one willing to engage in harder, less visible conversations about data quality, platforms and operating models.

Because in the next phase of B2B marketing, alignment with IT won’t be optional. It will be a leadership test.
