1. Apollo: best for data plus outreach
Best for: Teams that want contact data and outreach in one platform
Apollo gives small and mid-size teams most of what an expensive data contract offers, at a price a startup can manage. It pairs a large contact database with sequences, a dialer and a Chrome extension.
- Starting price

- Paid tiers from
- $65 a seat

- 240M+ contacts, 30M+ companies

Overview
Apollo's site lists more than 240 million contacts and 30 million companies, with waterfall enrichment, an AI assistant and a parallel dialer. On monthly billing the free plan includes 75 credits per seat, Basic costs $65 per seat for 2,500 credits, and Professional costs $99 per seat for 4,000 credits. The Organization plan is $149 per seat, annual only, with a three-seat minimum. Credits are pooled across the team and don't roll over.
How Apollo works
You filter the database by company size, industry, location, job title and technology, then reveal emails and phone numbers with credits. From there you can enrol contacts in cold email sequences, call them from the dialer or sync them to your CRM, so prospecting and outreach happen in one place.

What does a B2B data provider do?
A B2B data provider maintains a database of companies and the people who work at them, and sells access to it. Typical fields include company size, industry, revenue band, technology used, job titles, emails and phone numbers.
The better providers keep that data fresh by verifying it continuously and add signals on top: which companies are hiring, raising money, researching a topic or visiting your website. Those signals help you contact the right accounts at the right time.
Data providers overlap with email finders but go wider. If you only need emails for people you've already found on LinkedIn, our list of LinkedIn email finders covers lighter, cheaper tools.
Contact data, company data and intent signals
Not every provider is strong at everything. It helps to think in three layers, and to pick the provider that covers the layer your team relies on most.
| Provider | Strongest layer | Extras |
|---|---|---|
| Apollo | Contacts plus outreach | Sequences, dialer, Chrome extension |
| ZoomInfo | Company depth and intent | Hierarchy data, buyer intent |
| UpLead | Verified contacts | 95% accuracy guarantee |
| Dealfront | Website visitors | Company scoring, ad audiences |
| Lusha | Quick contact lookups | Signals, lookalikes, API |
Intent data is the newest layer and the most expensive. It's most useful for teams selling to large accounts with long sales cycles, where knowing who is researching your category makes outreach far more relevant.
How B2B data providers charge
Most providers sell credits: you spend one to reveal a contact's email or phone number. Some include a monthly allowance per seat, others share credits across the team, and a few, like Dealfront, price by the volume of companies identified.
| Provider | Free option | Paid plans from |
|---|---|---|
| Apollo | Free plan, 75 credits a month | $65 a seat |
| ZoomInfo | Free trial | Not published |
| UpLead | 7-day trial | $99 a month |
| Dealfront | Free Lite plan | €113 a month |
| Lusha | Free plan, 40 credits a month | $49.90 a month |
Enterprise providers often require annual contracts and don't publish prices. If you're a small team, start with a provider that offers a free plan or trial and test the data on your own target accounts before committing.
Data protection and responsible use
Buying B2B data doesn't remove your responsibilities. In the EU, personal data used for sales outreach falls under data protection law, and the European Commission's guidance sets out what businesses must do when they process it.
In practice that means having a lawful reason to contact people, telling them where you got their details if they ask, and honouring opt-outs quickly. For a plain-language overview, see what GDPR covers.
Ask any provider how it sources its data and how it handles removal requests. Clear answers are a good sign.
Using B2B data alongside LinkedIn
Data providers work best when they feed a multi-channel approach: email and phone from the provider, and personal outreach on LinkedIn. Prospects who see your name in more than one place are more likely to reply.
For the LinkedIn side, we compare outreach tools in our LinkedIn automation hub, where every review explains how safely a tool works within LinkedIn's limits.
Aimfox is the LinkedIn outreach tool we rate highest. Our Aimfox review explains how it can build campaigns from post engagers and event attendees, a useful complement to a database-led list.
How to choose a B2B data provider
Match the data to your sales motion
Outbound teams need contact details and filters. Inbound-heavy teams often get more from website visitor data like Dealfront's. Enterprise teams selling to large accounts benefit most from intent signals.
Separate company data from contact data
Some providers are strongest on firmographics such as size, revenue and technology, others on direct emails and mobile numbers. Check which one you'll use most before comparing prices.
Watch the credit rules
Apollo's credits expire each billing cycle, while other providers reveal contacts one credit at a time. Estimate how many contacts you'll really use each month and price that, not the headline plan.
Plan for your CRM
Data is only useful once it reaches the tools your reps use. Check the integrations, and whether syncing is two-way or one-way, before you sign up.
Ask about compliance
If you sell into Europe, ask each provider how it collects data and handles opt-outs. A reputable provider will answer clearly and give you tools to stay compliant.

FAQ
What is the best B2B data provider?
For most teams we'd start with Apollo, since it combines a database of 240M+ contacts with outreach tools and a free plan. ZoomInfo is stronger for enterprise teams that need intent data and can budget for an annual contract.
Is there a free B2B data provider?
Apollo, Dealfront and Lusha all have free plans. Apollo includes 75 credits a month, Dealfront's Lite plan identifies 100 companies a month, and Lusha gives 40 credits a month.
How much does ZoomInfo cost?
ZoomInfo doesn't publish prices on its website. Plans are quoted by its sales team, and a free trial is available.
What's the difference between a data provider and an email finder?
Email finders focus on getting a contact's email, often from LinkedIn. Data providers go wider, with company profiles, technology data, intent signals and sometimes website visitor identification.
Is buying B2B data legal?
Generally yes, but how you use the data is regulated. In Europe, GDPR applies to outreach, so you need a lawful basis to contact people and must respect opt-outs.
Do I still need LinkedIn if I have a data provider?
Usually yes. Data gives you emails and numbers, but LinkedIn is where prospects check who you are. Combining both channels tends to get more replies than either alone.
