The 5 habits of highly effective marketing teams

What do you believe is the biggest hurdle to marketing growth today? 

I believe it’s speed, specifically, speed of iteration. Slow marketing cycles kill momentum.

In my years as a tech operator and investor, I’ve seen this play out time and again. It’s tough to create meaningful business growth when launching a new campaign takes weeks. And even tougher when it takes just as long to measure how a campaign change impacts results. 

I’ve developed my own theories about what makes a marketing team nimble. But theories aside, data is more compelling — and now we have it.

Recently, GrowthLoop partnered with Ascend2 to produce the 2026 AI and Marketing  Performance Index, a comprehensive report based on a survey of 300+ marketers. The goal: to understand what truly drives marketing effectiveness and how AI is reshaping the playbook.

The results benchmark against the 2025 findings and echo what I’ve long believed: high-growth companies move fast. The teams achieving the strongest revenue growth are significantly more likely to prioritize speeding up execution and can use real-time context for stronger results. 

In the survey, just 5% of teams can launch a campaign in under a week. A larger group can launch in 7-15 days (20%) and the majority require 16-30 days (34%). Optimizing campaigns is an entirely different challenge, as over one-third of teams (35%) need one to two months to see the impact of a campaign change. 

Accelerate marketing cycles to drive growth

So, how can your team build momentum to drive significant, lasting growth? The report surfaced five key habits of highly effective marketing teams.

1. Unify strategy and systems

Throughout my career, I’ve seen how slow, manual processes quietly kill momentum. The culprit usually isn’t one big roadblock; it’s a thousand small delays. 

The flipside is also true: by speeding up every little part of the process, efficiencies compound in a virtuous cycle — what we at GrowthLoop call compound marketing. 

In the survey, marketers were asked about the biggest barriers preventing their teams from moving faster. The top responses were telling:

• Delayed approvals and decision-making (36%)

• Limited resources and budget (31%)

• Manual processes and limited automation (31%)

• Dependence on other teams (28%)

• Siloed data (27%)

These challenges share a common theme: inefficient workflows caused by fragmented systems. 

Marketing teams today must work closely alongside their data counterparts. CIOs and CMOs should be best friends. That means aligning on a strategy and system that provides marketers with self-serve access to data without compromising the key infrastructure maintained by the data teams.

Without this alignment, marketers will continue to sink time into endless back-and-forth. They’ll battle inaccurate customer data that’s spread across systems, slowing their ability to launch campaigns, leverage AI effectively, and ultimately drive growth. So break down those siloes — and get everyone on the same page.

2. Unlock real-time customer data for marketers and AI

Effective marketing isn’t just about moving fast, it’s about staying nimble, testing, and iterating. And you can’t do that without accurate, real-time customer data. 

Nearly half of marketers surveyed cited data analysis and insights (46%), campaign development (45%), and personalization at scale (44%) as their biggest bottlenecks. And those numbers don’t surprise me at all. Many organizations I talk to face similar issues — marketers struggle to get their hands on usable data, and when they do, it takes time to analyze.

Just 46% of marketers said they have a fully centralized and actively used single source of customer truth. Nearly half of those teams (44%) reported seeing significant revenue increases in the last year. Of the 54% of teams with partial or no centralization, just 8% achieved significant revenue increases. 

Whether it’s a marketer or an AI agent, the data they access must be centralized and accurate — a single source of truth in the enterprise cloud. This allows for real-time access, keeps sensitive data in place, and enables marketers to move more quickly from insight to execution.

3. Layer in AI to supercharge campaigns and compound growth

There’s no denying the hype around AI. And the hype is deserved. But I’ve also seen companies get distracted trying to apply AI everywhere at once, rather than starting where it delivers the most value. 

The biggest productivity gains from AI happen when it turns data into real-time insights and accelerates campaign testing and iteration. Marketers still need to bring the strategy, the creative direction, and the instincts that resonate with customers. But a well-trained AI agent can test 100 different customer segments faster and more thoroughly than a person ever could. 

In our survey, marketers reported using autonomous AI for the following use cases, empowering them with analytical insights to accelerate execution: 

• Generating insights and recommendations (26%)

• Predicting customer behavior (19%)

• Optimizing campaign journeys (19%)

The takeaway: don’t chase shiny AI demos. Use it where it drives real acceleration and compounds growth.

4. Always keep a human in the loop and invest in AI talent

AI can do a lot, but I don’t believe it can fully replace the job of a marketer. Great marketing still relies on human intuition, judgment, and creativity. AI is most powerful when it augments marketers, not when it tries to replace them. 

Our survey backed this up: 81% of marketers agreed that human input improves AI performance. 37% believed AI should only provide insights and recommendations while humans make all final decisions. Only 15% felt comfortable giving AI meaningful autonomy. 

To get the most out of AI, teams need marketers who know how to wield it. That means hiring for AI fluency and investing in training. In the survey, 27% of marketers said hiring AI-savvy talent was a priority, and 62% reported they were actively upskilling current teams in AI proficiency. 

Bottom line: AI is only as good as the people using it. Treat it as a capability to build, not a black box to plug in.

5. Get execs on the same page

Every time a new technology raises productivity, it also raises expectations. 

As marketing teams navigate pressure to move faster and prove results, they need more than new tools; they need support. Integrating AI, speeding up cycles, and launching more personalized campaigns often require changes to budget, workflows, and even culture. These changes won’t stick without executive buy-in.

It also means executives need to dig in themselves; learn how to use AI in your day-to-day and get familiar with the tech. Walk the walk and talk the talk. 

But here’s the challenge: our data suggest that executives are significantly more likely to cite manual processes and limited automation as success barriers. They’re also twice as likely to report low confidence in test results. That disconnect creates risk. What’s needed is more honest dialogue between leadership and the folks in the trenches. Only then can companies adopt new tools, adjust strategies, and ultimately move — and grow — faster.

The new compound marketing playbook

Faster marketing cycles mean faster growth. The question is how to build speed — and how to sustain it. As our survey suggests, real-time access to data is foundational. Marketing and data teams need to work in sync, enabling marketers to self-serve from a single, centralized source of truth in the cloud.

But access is just the beginning. The real gains come from what you do with the data. This is where AI changes the game. With the right tools in the hands of AI-savvy marketers, teams can generate sharper insights, smarter predictions, and highly personalized campaigns at scale. To get there, companies need to invest in talent and secure executive buy-in to align priorities.

Put it all together, and you're not just speeding up the marketing cycle — you’re building a flywheel for lasting growth.
