Beyond Martech: How the signal economy is rewriting marketing performance

The marketing playbook is being quietly rewritten. Not through a new platform or a breakthrough format, but through something far less visible and far more consequential. Data signals. As artificial intelligence begins to compress the application layer of marketing, the tools that once differentiated brands are starting to look increasingly similar. Dashboards, reporting, optimisation, workflows. Much of it can now be replicated with speed and ease.

What is emerging in its place is a deeper and more structural shift. Competitive advantage is moving away from the interface and into the infrastructure beneath it. The real question is no longer what tools a brand uses, but what data those tools run on. This is the rise of the signal economy, where the quality, ownership, and reliability of data signals determine how effectively marketing works and how efficiently businesses grow.

For brands, this marks a significant inflection point. Marketing success is no longer just about budgets, reach, or creative execution. It is about whether the signals feeding automated systems are clean, connected, and tied to real business outcomes. In an AI-led environment, signals are not just inputs. They are decision drivers that shape how money is spent and where growth comes from.

When Automation Amplifies the Wrong Signals

Across industries, marketers are beginning to see how fragile this system can be when signal quality is compromised. Campaigns that appear efficient on dashboards often fail to translate into tangible business outcomes.

“I have seen campaigns look efficient inside a dashboard, but when you go back and check the real business outcome, the lift is not there. That usually means the system was learning from the wrong cue,” says Gaurav Sehgal, VP Marketing, Medusa Beverages.

This disconnect highlights a deeper issue. Marketing systems are often optimising for activity rather than impact, rewarding metrics that look strong on paper but do not move the business.

“The most classic example is automated retargeting running on stale audience data,” says Chirag Taneja, CEO and Co Founder, GoKwik. “The algorithm optimises hard, spends fast, and ends up hammering people who already bought or audiences with zero purchase intent. Automation did not fail. The signal did.”

Because automation operates at scale, the cost of poor signals compounds quickly.

“A bad signal can bleed budget ten times faster than a manual campaign ever would,” Taneja adds.

From Tool Advantage to Signal Advantage

For years, marketing technology promised differentiation through capability. Better targeting, faster optimisation, and smarter reporting were seen as levers of competitive advantage. But AI is rapidly neutralising that edge. What once required specialised platforms can now be generated through prompts and automation, making tools increasingly interchangeable.

The result is a levelling of the tool layer. But instead of democratising performance, it is creating a new divide. The advantage is shifting to brands that have stronger, more reliable data foundations.

“The problem is not access to tools. It is signal quality and data discipline,” says Shagun Walia, Marketing Communications, Avery Dennison - South Asia and SSA. “Salesforce says 84 percent of marketers are already using first party data, but only 31 percent are fully satisfied with data unification. That gap tells you where the real issue sits.”

That gap becomes more critical as automation scales. AI systems do not question the data they receive. They act on it, often at speed and at scale.

“Automation is only as good as the signals it receives. If the inputs are messy, duplicated, incomplete, or disconnected from actual business outcomes, then automation does not correct that. It simply repeats it faster,” Walia adds.

First Party Data Moves to the Core

In response, brands are rethinking where their most valuable signals originate. Increasingly, the answer lies within their own ecosystems. First party data is no longer just a compliance requirement. It is becoming the backbone of marketing decision making.

“The way around this is to build a stronger layer of data we own,” says Walia. “Cleaner first party capture, better CRM mapping, enhanced conversions, offline conversion imports, and regular checks against business outcomes instead of trusting platform numbers blindly.”

This shift is also being driven by the limitations of walled gardens. While platforms remain powerful for reach and activation, they often provide only a partial view of customer behaviour. “The platforms grade their own homework,” says Taneja. “They will show you ROAS within their walls, but validating whether that reflects actual revenue is genuinely hard.”

Brands are responding by building independent signal layers that allow them to cross check performance and connect customer journeys across touchpoints. “At GoKwik, we focus on checkout behaviour, payment patterns, and conversion signals across our network. That becomes our source of truth to pressure test what platforms report,” Taneja explains.

The Rise of the Validated Signal Layer

A key development within this shift is the growing importance of what marketers call the validated signal layer. This is where raw data is cleaned, structured, and tied back to real outcomes such as revenue, retention, or customer value.

“The difference is often less about one dramatic number and more about the quality of the decision you make after the campaign,” says Walia. “Platform reported conversions can look stronger in the short term, but once you validate those signals against CRM or revenue, you see where the noise was hiding.”

Sehgal echoes this perspective, emphasising the need for a more grounded view of performance. “Platform reported conversions are useful for speed, but they can also be self serving. Your own validated signal layer tells you what actually helped the business,” he says.

Over time, this approach leads to more efficient decision making. Budgets naturally shift toward signals that reflect real business movement rather than superficial engagement. “When you stop over rewarding the wrong signal, your budget naturally moves to better places. You waste less, learn faster, and make cleaner decisions,” Sehgal adds.

Signal Strategy Becomes a Business Function

As signals become central to marketing performance, they are also reshaping how organisations operate. Signal strategy is no longer confined to marketing teams. It is becoming a cross functional responsibility that spans product, data, sales, and finance. “If it sits purely in marketing, you have already lost,” says Taneja. “At GoKwik, this lives between product and data. Marketing is a consumer of the output, not the owner of the infrastructure.”

This shift reflects the reality that signals are generated across multiple touchpoints and need to be interpreted in a business context.

“I see signal strategy as a cross functional responsibility,” says Walia. “If marketing owns it alone, it becomes a reporting exercise. If the business owns it together, it becomes a growth system.”

Sehgal reinforces this view from an operational standpoint. “Marketing sees the story. Sales sees what is happening in the market. Trade tells us what outlets are doing. Finance helps us understand whether the momentum is efficient. When you put those together, you get a much better view of the business.”

A Widening Gap in Marketing Performance

What is emerging from this shift is a new competitive divide. Not between brands with larger budgets and those with smaller ones, but between those with strong signals and those without.

“We see this go wrong quite often. If you automate a process using messy data, you are basically scaling your mistakes,” says Shivkumar Borade, Founder and CMD, Borade AI.

Conversely, brands that invest in clean and connected data foundations begin to see compounding advantages over time. “Better signals do not just improve reporting. They improve commercial outcomes,” Walia notes.

This divergence becomes more pronounced as AI systems learn and optimise. Strong signals lead to better decisions, which generate stronger signals. Weak signals, on the other hand, create a cycle of inefficiency.

“Wrong audiences get scaled faster, budgets get optimised toward low quality conversions, and remarketing loops keep chasing the same users,” says Yasin Hamidani, Director, Media Care Brand Solutions. “Volume looks strong on paper, but actual business outcomes are weak.”

The Future Is Built on Signal Architecture

The implications of the signal economy extend beyond marketing into the broader business ecosystem. Brands are beginning to rebuild their data foundations, investing in first party ecosystems and strengthening integration across platforms.

To navigate the limitations of closed ecosystems, companies are focusing more on the data they directly control. “We lean on CRM records, site visits, and app activity to build a clear picture ourselves,” says Borade. “Our AI makes better calls when it is looking at real facts rather than platform snapshots.”

This marks a shift from campaign led thinking to system driven thinking. Marketing is no longer just about execution. It is about building the infrastructure that enables better decisions at scale. In this new reality, competitive advantage will not come from better tools or higher spend. It will come from stronger signal architecture. Brands that invest in clean, connected, and reliable data will be better positioned to navigate an increasingly automated landscape.

As AI continues to take over execution, the question is no longer how marketing is done. It is what it is done on. And that answer will define the winners in the years ahead.
