Say you have 500 target accounts in your CRM. You have company names and websites, and that is about it. To run outbound you need the people at those companies, working emails that won't bounce, and enough context to write something relevant. You can buy one big database license, stitch together three or four tools, or first work out what B2B data actually is and which parts of it you need.
This guide covers the main types of B2B data, where each type comes from, how to test quality before you pay for it, and how to set up an enrichment workflow that keeps the data usable after the first month.
The short version
B2B data falls into six rough categories: contact, company, technographic, intent, funding and financial, and social. Most sales teams live on the first three.
Quality beats volume. A list of 500 verified contacts will get more replies than 5,000 unverified ones, and it won't damage your sending domain.
No single provider has good coverage everywhere. Querying several sources in sequence fills gaps that any one database leaves.
Contact data goes stale because people change jobs. Plan a refresh cycle from day one.
The six types of B2B data
1. Contact data
Information about individual people. Every outbound motion starts here, and it is also the category that decays fastest. The US Bureau of Labor Statistics put median tenure with a current employer at 3.9 years in January 2024, and 2.7 years for workers aged 25 to 34. A contact record that was right last year has a real chance of being wrong today.
The fields that matter:
Work email. The main field for outbound. Verify it before you send.
Direct dial or mobile. Needed for cold calling and multi-channel sequences. Harder to find and more expensive than email.
Job title and seniority. Tells you whether this is the buyer, an influencer, or someone who will forward your email to nobody.
LinkedIn URL. The most reliable unique identifier for a person, and a good input for further enrichment.
Department. Useful for routing to the right rep or campaign.
2. Company data (firmographics)
Information about the organization. This is what you filter your ICP on and what most account scoring models use. Employee count is usually the most dependable sizing field because it can be cross-checked against LinkedIn. Revenue is useful for budget signals but is an estimate for almost every private company, so treat ranges loosely. Add industry and sub-industry, HQ location (for territories and compliance), and founding year, which is a decent proxy for growth stage.
3. Technographic data
The software and infrastructure a company runs. For many B2B sellers this is the most useful signal after headcount, because it shows competitive context (they use a rival product), integration fit (they use the CRM you plug into), and sophistication (a 30-person company running Snowflake and dbt is not a typical 30-person company).
Common categories people enrich for:
Category | Examples |
|---|---|
CRM | Salesforce, HubSpot, Attio, Close |
Marketing automation | Marketo, Pardot, Mailchimp |
Sales engagement | Outreach, Salesloft, Apollo |
Cloud | AWS, Google Cloud, Azure |
Product analytics | GA4, Mixpanel, Amplitude |
One caveat: technographic tools detect what is visible from the outside, mostly scripts and tags on public web pages. Back-office software often doesn't show up. We go deeper on this in our guide to checking what tech stack a company uses.
4. Intent data
Signals that a company is researching a problem or a product category right now. Intent answers when to reach out, which contact and company data can't. Sources include identified visits to your own website, review-site activity on G2 or Capterra, topic consumption across publisher networks, and engagement with category ads. Intent is noisy, so it works best as a prioritization layer on top of an ICP-qualified list, not as a list source on its own. Our post on using intent data in B2B sales covers how to act on it.
5. Funding and financial data
Funding rounds (stage, amount, date, investors), revenue estimates, M&A activity, and public filings. A fresh round usually means new budget and new hires, which is why funding events are one of the most common outbound triggers. For public companies, SEC filings are authoritative. For private ones, you are relying on announcements and aggregators like Crunchbase.
6. Social and behavioral data
Public activity that shows what someone cares about: LinkedIn posts and comments, job changes, podcast and conference appearances, and participation in communities. This data rarely drives targeting by itself. It is most useful for the first line of an email and for spotting job changes among your existing customers' champions.
Where B2B data comes from
Every provider gets its data from some mix of the sources below. Knowing which one a vendor relies on tells you where it will be strong and where it will be thin.
Source type | Examples | Strengths | Limitations |
|---|---|---|---|
Contact databases | Apollo, ZoomInfo, Cognism | Large pre-built databases, search filters | Coverage varies by region and segment; often annual contracts |
Web crawling | BuiltWith, Wappalyzer | Current tech stack detection | Only sees technology exposed on the web |
Public filings and registries | SEC EDGAR, Companies House, Crunchbase | Authoritative for what they cover | Mostly public companies and funded startups |
User-contributed profiles | LinkedIn, G2, Glassdoor | Rich role and review detail | Self-reported, updated whenever the person bothers |
Aggregators | Databar (160+ providers) | Several sources behind one workflow, waterfall enrichment | Quality still depends on the underlying providers you pick |
How to evaluate data quality
Vendor demos always look good because the vendor picks the examples. Judge a provider on five things instead.
Accuracy: is the value correct today?
Coverage: what share of your own target list comes back with a result?
Freshness: when was the record last confirmed?
Completeness: does a record have all the fields you need, or an email with no title?
Verification: is an email confirmed deliverable, or merely "found" by pattern guessing?
A test you can run in an afternoon
Pull 500 records from your CRM, ideally ones where you already know the right answer (recent customers, closed-won contacts). Run them through each provider you are considering, then count:
How many records returned anything (coverage).
How many returned emails pass a verification check (accuracy).
How many have every field you need filled in (completeness).
How many titles match the person's current LinkedIn profile (freshness).
Use your real ICP, not a random sample. A provider that is excellent on US tech companies can be weak on German manufacturers, and the only way to find out is to test on the accounts you actually sell to.
Building a B2B data workflow in Databar
Databar puts 160+ data providers behind a spreadsheet-like table, so each step below is a column rather than a separate tool and export. A typical setup looks like this.
List building
Start from your CRM export, a CSV, or a company search from one of the provider sources. Add firmographic and technographic columns and filter down to the accounts that fit your ICP before you spend anything on contacts. Our step-by-step guide to building B2B lead lists walks through the filtering logic.
Contact enrichment
For each qualified account, find the people in the roles you target, then add a work email column as a waterfall. A waterfall tries providers in the order you choose and stops at the first valid result, so a contact that one database misses gets a second and third chance. If you want the mechanics, see how waterfall enrichment works.
Verification
Run found emails through a verification provider before anything goes into a sequence. Pricing is credits-based and you are charged for results, not for lookups that come back empty.
CRM sync and refresh
Push enriched fields to HubSpot or Salesforce, then put the table on a scheduled run so titles and emails get re-checked on a cadence instead of once. For active outbound lists, monthly is reasonable. For the full CRM, quarterly is usually enough. The CRM enrichment guide covers field mapping and overwrite rules.
Multi-step pipelines
When the process has several stages (find company, qualify, find contacts, verify, research, push), Flows lets you chain them on a visual canvas. Add an AI Researcher step if you want a line of per-account context from the web, such as a recent product launch, to use in your opener. Developers can run the same enrichments through the REST API, Python SDK, or the MCP server.
Common questions
What B2B data do most sales teams actually need?
A verified work email, current job title, company size, and industry cover most outbound campaigns. Add a direct dial if you call, technographics if your product integrates with or replaces something, and funding data if timing matters for your sale.
What is the difference between contact data and company data?
Contact data describes a person (email, phone, title, LinkedIn). Company data describes the organization (size, revenue, industry, tech stack). Company data decides whether an account is worth pursuing and what to say. Contact data decides who hears it.
How often should B2B data be refreshed?
Re-verify emails right before any campaign, refresh active prospect lists monthly, and re-enrich the wider CRM quarterly. Job changes are the main reason records go bad, and they happen continuously, not once a year.
Why use several providers instead of one?
Each database is built from different sources, so each has different blind spots. Running a waterfall across several gives you higher match rates than any one of them alone, and if you only pay for results, the extra providers cost nothing on the records they miss.
If you want to run the 500-record test on your own list, Databar has a 14-day trial of the full product, and paid plans start at $99/month.
