GTM Data Intelligence

The Intelligence Layer
Your GTM Team is Missing

You don’t need another tool. You need someone to clean your CRM, fill the gaps, research your prospects and make sure your pipeline is built on truth - month after month.

40% of your CRM data goes bad within a year. Quietly.

Job titles change. Companies fold or pivot. People move on. And yet your reps are still calling numbers that ring to voicemail at old employers, sending sequences to someone who left six months ago, and wondering why conversion rates are soft. According to Gartner research, organisations that invest in data quality see 70% faster revenue growth than those that don’t.

It’s not a tool problem. Tools are everywhere. It’s a data problem - and no one’s job to fix it.

Meanwhile, the pipeline review reveals contacts with no phone, no title, no recent activity. Dozens of duplicates. Records sourced from a list bought three years ago that was already stale when you bought it. Salesforce research estimates that sales reps spend 27% of their time on data entry and record maintenance instead of selling.

What Clients Say

Kayden

Reply rate doubled in one month

We exported 4,200 records before the audit. ClientWise came back with 900 flagged as duplicates, 600 with outdated job titles, and 300 with no contact data at all. After importing the cleaned file, our outbound reply rate went from 2.8% to 6.1% within a month. The health report also made it very easy to explain to the board why our numbers had been soft.

Sarah Chen, Kayden

Head of Revenue Operations

Reachflow

Forecast variance dropped from 35% to under 12%

We’d been putting off a CRM cleanup for two years. The scoping call took 25 minutes, SOW landed that afternoon, and the cleaned export was back in our CRM within a week. Pipeline accuracy improved immediately — our forecast variance dropped from 35% to under 12%. Wish we’d done it sooner.

Frequently Asked Questions

For a CRM Quality Audit, a CSV export of your existing records is enough - whatever fields you have. For an ICP-Verified Prospect Pool, we need your ICP: target industries, company size, geographies, and the job titles you sell to. The free 30-minute scoping call covers all of this, and we will tell you exactly what we need before any work begins.

Read our CRM audit guide

We deliver to HubSpot, Salesforce, Pipedrive, and most other CRMs via CSV import. For HubSpot and Salesforce, we format the export specifically for their native import flows so you can upload without reformatting. There is no integration to configure or API to set up - we handle the formatting and deduplication before delivery.

See our HubSpot audit walkthrough

Most projects deliver within 5-10 business days. A CRM Quality Audit on 2,000 records typically takes 5-7 days. An ICP-Verified Prospect Pool of 500 verified prospects is usually 7-10 days. There is no software to learn, no onboarding process, and no ramp-up period. You brief us on the scoping call and receive verified data back within days.

See what a retainer delivery looks like

Common warning signs: emails bouncing above 3%, SDRs reporting wrong numbers or outdated job titles, duplicate records appearing in reports, missing fields on a large percentage of contacts, or records sourced from a purchased list more than 12 months ago. If any of these sound familiar, your data is costing you pipeline. Our first audit typically flags 34% of records as needing attention.

7 signs your CRM data is killing your pipeline

A one-off audit solves the immediate problem, but B2B data decays at roughly 2-3% per month. After 12 months without maintenance, nearly a third of your records will be outdated again. Most teams start with a CRM Quality Audit to fix the backlog, then move to an Always-Fresh Pipeline Retainer to stop the decay cycle permanently.
