There has never been a better time for Marketing and Sales to collaborate more effectively

Matthew Park, Managing Director, South Korea

If you work in Sales or Marketing you’ve probably heard something like this at least once. Perhaps you have experienced it yourself:

• “The leads we get from marketing aren’t very good.”

• “Even when leads are passed on, the sales team doesn’t move quickly.”

To be blunt: if this is happening, it’s because in 2026 teams are using a 10-year-old playbook. Having myself worked in both marketing and sales, I understand and resonate with both perspectives.

Speaking a different language

This issue is often seen as KPI misalignment. If you look deeper, it’s not just about goal setting. At its core, the problem is that sales and marketing teams are speaking different languages. Marketing designs messaging based on personas, while sales drives conversations around customer pain points.

On top of that, the definition of a ‘lead’ may be different for each team. The clue is there in the names. Sales wants SQLs that convert, while marketing needs to generate MQLs to sustain the pipeline. Sale professionals focus on customers who may convert immediately, whereas marketing teams are seeking to engage future potential customers.

Left unchecked this gap will only continue to widen. The good news is that there has never been a better time for marketing and sales to collaborate more effectively. There’s one reason: AI.

Data discipline and AI as a solution

With the emergence of MarTech tools such as Gong, Jeeva, Clari, and HubSpot AI, it’s now possible to unify these gaps and differences through a common language: data.

In the past, both sales and marketing teams knew that they should share discovery calls, campaign results, and customer insights. Due to workload, priorities, and organizational structures, this rarely happened effectively.

Sales had Excel files on personal computers. Marketing used CRM systems. Pipelines were tracked in another tool. Meetings and communication happened on yet another platform. Data was fragmented everywhere.

There’s no longer any excuse for that situation to exist. When data is centralized, AI can analyse call data, interpret customer signals, and automatically generate insights based on behavioural data.

It’s no longer a question of ‘should we share this or not?’ We’re in an era where data is already structured and provided as a shared language.

Now, we can evaluate the following using the same standards:

• Buying signals

• Customer intent

• Content consumption patterns

• Pipeline health

• Competitive analysis metrics

Especially when based on first-party data, all of this can be monitored in real time. And this data is no longer just opinion – it’s the foundation for decision-making.

Intercepting the changing buyer journey

The customer buying journey has also changed significantly. Search is increasingly moving toward zero-click. Sales infrastructure is being reorganized around AI. Customer experience now demands hyper-personalization and automation at scale by default.

In the past, doing both hyper-personalization and large-scale nurturing at the same time sounded like an oxymoron. Now, we can and must do both.

At its core, hyper-personalization means reaching the right customer, at the right time, through the right channel, with the right message. And this experience must remain consistent across every touchpoint the customer has.

What makes all this possible comes down to one thing: data integration.

Right data in the right place

If data remains fragmented, then AI, collaboration, and hyper-personalization simply won’t work effectively.

Only when data is unified can the following truly happen:

• Data integration

• AI-driven analysis and structuring

• Insight generation

• Action planning

• Hyper-personalized journey design

• Continuous optimisation

Finally, I’d like to leave you with one question: are we still trying to persuade each other, or are we discussing based on the same data? This difference will likely determine the future performance of both marketing and sales.
