How do you evaluate the data accuracy of a sales intelligence tool?

Evaluate data accuracy by running a sample of your ideal customer profiles through the platform and manually verifying the results. Check email bounce rates (aim for under 5%), call connection rates for direct dials, and cross-reference company firmographics with public records. Most vendors offer a trial or a data sample test for this purpose.

What are the key features to look for in a sales intelligence platform?

The key features are a large, accurate contact and company database, buyer intent signals, CRM integration, and data enrichment. Look for advanced filters to build precise lists (e.g., by technology used, company size, hiring trends), real-time data verification, and compliance with regulations like GDPR.

How does intent data actually work?

Intent data works by tracking the online behavior of users from specific companies to see what business topics they are researching. This is often done by monitoring content consumption across a B2B publisher network. When multiple employees from one company research a topic like 'CRM software pricing', the platform flags that account as showing buying intent for CRMs.

How to choose

1. 1Define your primary use case: Are you looking for raw contact data, account-based intent signals, or workflow automation? No single tool is best at everything.
2. 2Assess your geographic focus: If you sell heavily into EMEA, a provider like Cognism with strong GDPR-compliant European data is critical. For North America, ZoomInfo or Apollo.io have deep coverage.
3. 3Audit your tech stack: Ensure the platform has native, well-supported integrations with your specific CRM (e.g., Salesforce, HubSpot) and sales engagement tools (e.g., Outreach, Salesloft) to avoid manual data transfer.

What is a sales intelligence platform?

A sales intelligence platform is a software tool that helps salespeople find, understand, and connect with potential customers. It provides B2B contact and company data, buying signals (like which companies are researching your solution), and tools to streamline the prospecting process.

How is sales intelligence different from a CRM?

A CRM (Customer Relationship Management) system manages your existing relationships with prospects and customers, while a sales intelligence platform helps you find new prospects to put into your CRM. The intelligence tool is for discovery and enrichment; the CRM is for relationship management and tracking deals.

What is the difference between intent data and contact data?

Contact data is information about an individual, such as their name, job title, email address, and phone number. Intent data is information about an account's (company's) online research behavior, indicating they may be in the market for a particular product or service. You use intent data to find the right accounts, then use contact data to find the right people at those accounts.

How much do sales intelligence tools cost?

Sales intelligence tools typically cost between $50 and $500 per user per month. Pricing varies based on the number of users, data credits needed, and access to advanced features like buyer intent data. Enterprise-level platforms like ZoomInfo and 6sense often require custom annual contracts that can exceed $25,000.
