Poor data quality undermines AI sales tools before they start, ZoomInfo says

AI Isn't Enough: What Companies Need to Fix Before Their Sales Results Will Change

Many companies are deploying AI-powered sales tools across their go-to-market teams, yet revenue projections remain flat, conversion rates stagnate, and frontline sellers grow frustrated. The problem isn't the technology. It's the data underneath it.

Poor data quality is the fundamental issue most businesses are struggling with, according to ZoomInfo research. AI tools analyze and act on information that already exists in CRM records, prospect lists, contact databases, and account histories. If that underlying information is inaccurate, incomplete, or outdated, AI simply accelerates bad outcomes.

Why AI Investments Fail

Some companies are seeing results. Many others have invested heavily in AI-powered tools, deployed them across GTM teams, and still aren't seeing the results they expected.

Survey data from ZoomInfo shows that 84% of GTM leaders experienced negative performance stemming from poor data quality in 2025. One in four GTM leaders aren't confident their GTM data is updated in real time to reflect key changes. Two in five enterprise GTM leaders share similar concerns about the reliability of real-time data at their disposal.

Only half of GTM leaders are satisfied with their customer and prospect data. Critical gaps include integration across systems, intent and buyer signals, data completeness, and the ability to deduplicate redundant records.

The Confidence Problem

Bad contact information stops frontline sellers from trusting the system. They start manually verifying everything, defeating much of the efficiency AI was supposed to create. Worse, they stop using the tools altogether and revert to workflows they were comfortable with before.

Managers who have watched AI-generated forecasts miss the mark a few times in a row lose confidence in the models. They start overriding recommendations based on gut feeling, which reintroduces the kind of inconsistency AI was meant to eliminate.

This erosion of trust is slow but toxic to technology investments. It almost always traces back to AI promising results it cannot deliver because the data powering it isn't reliable enough to deliver them.

What Actually Needs to Change

Most companies understand that their data quality isn't perfect, but very few take the time to quantify it. How many CRM contacts have verified, current email addresses? What percentage of accounts have accurate employee counts and revenue figures? How often is contact data refreshed? These are vital diagnostic questions. The answers will reveal more about sales performance than almost any other metric.

One of the most common mistakes organizations make is treating data quality as a one-time initiative owned primarily by IT. Data decays continuously, so the solution has to be continuous too. That means building processes or partnering with providers that keep your information current on an ongoing basis, not just when someone notices a problem.

Data quality is a cultural challenge as much as an operational one. Organizations that take this seriously treat accurate, current data as a business priority. They assign visible champions at the leadership level and hold stakeholders across every major department of the business accountable.

The Real Competitive Advantage

AI is a genuine force multiplier in sales. Companies that learn to use it well will have real advantages over those that don't. That multiplier only works, though, if the underlying foundation - the data, the processes, the systems of record - is reliable.

The companies seeing their sales results change are the ones doing the less exciting, less headline-worthy work of making sure that AI tools have a reliable foundation to build upon. They understand that data quality is a problem of discipline, not technology.

Solving it is entirely within reach, but only for the organizations willing to look at it honestly.
