Prospecting data tools answer two questions for a rep: which companies should I go after, and who inside them should I contact? They hold databases of companies with details such as industry, headcount, location and the technology they use, and of people with titles, departments, work emails and phone numbers. A rep filters the database to match an ideal customer profile, saves a list and sends it to a CRM or a sequencing tool.
Most tools here also do enrichment. Instead of starting with a search, you start with records you already have, such as inbound leads with only a name and email, and the tool fills in the missing fields. RevOps teams use enrichment to keep the CRM tidy, to route leads by company size or region and to score inbound leads before a rep sees them. Some tools run enrichment on a schedule, so job changes and company updates flow into the CRM without anyone asking.
The biggest difference between providers is coverage and accuracy in your market. A database can be strong for North American software companies and thin for European manufacturers, or good on emails and weak on mobile numbers. Vendors publish broad accuracy claims, but the only number that matters is how their data performs on your target list. Before you sign, send a sample of accounts you know well and check the contacts, titles and phone numbers you get back. Then send a small batch of emails and look at the bounce rate.
Data sourcing and privacy rules matter more here than in most sales categories. Contact data is collected in different ways: from public web pages, from user-contributed address books, from partners and from direct verification calls. Laws such as GDPR in Europe and various state privacy laws in the US put rules on how personal data can be collected and used for outreach. Ask each provider how its data is gathered, how people can opt out, and what it does when someone asks to be removed. Your own legal team should decide what outreach is allowed for your regions.

AI features in this category are newer. Some tools let you describe a target in plain language and turn it into filters, some score accounts on how closely they match your best customers, and some research an account and write a short brief or an opening line. Workflow tools such as Clay go further, chaining several data providers and AI steps so you can build lists a single database cannot, such as companies that recently posted a certain job or launched a product.
Pricing usually depends on seats and on credits for exports, emails revealed or phone numbers revealed. Credits run out faster than people expect, especially for mobile numbers, so look at how many records your team actually works each month. Also check whether data you export can be kept after the contract ends, since some agreements limit that.
A good setup for many teams is one primary data source for broad coverage, LinkedIn Sales Navigator for research and current job details, and a second source or verification step to fill gaps. Avoid buying three overlapping databases without a plan for which one wins when records disagree.
It varies by provider, region, industry and seniority, and it decays as people change jobs. The practical test is a sample from your own target list: check titles and phone numbers by hand and send a small batch of emails to see the bounce rate before you commit.
Rules differ by country. Some regions allow B2B cold email with a clear opt-out, while others are stricter about consent and how personal data is collected. Ask each provider how its data is sourced and talk to your own counsel about what outreach is allowed where you sell.
Enrichment fills in missing details on records you already have, such as company size, industry, title or phone number for an inbound lead. RevOps teams use it to route and score leads and to keep CRM records current when people change jobs.
LinkedIn profiles are often the most current record of a person's role, and Sales Navigator adds detailed search, saved lists and job change alerts. It does not provide emails or phone numbers, so most teams use it alongside a data provider.
Most charge per seat plus credits for exporting records or revealing emails and phone numbers. Mobile numbers often cost more credits. Estimate how many records your team works each month and ask how unused credits are handled.
