Top 10 Data Enrichment Tools [October 2025]
Reliable data enrichment tools are the one thing you can’t go without if you’re in B2B sales or marketing, as they enable:
- Highly targeted prospecting.
- More successful lead generation.
- Better conversion rates across channels.
In this article, we’ll offer a curated list of the 9 best data enrichment tools, analyzing each platform’s strengths, drawbacks, and pricing policies to help you make an informed decision.
But first, let’s quickly explain what factors you need to consider when choosing a data enrichment tool.
Key Things to Look for in a Data Enrichment Platform
1. Data Accuracy
Suppose a data enrichment platform keeps giving you inaccurate or stale data or struggles to find information on a lead. Your campaign’s response rate will be low, bounce rate high, and you’ll waste money buying crappy leads.
It’s the most common drawback flagged in public reviews for tools like ZoomInfo and Demandbase.

2. Data granularity
Some platforms provide only basic contact information, which is not enough to create efficient marketing and sales campaigns.
Without granular buyer intent data, you can’t qualify leads, recognize the hottest ones, and engage them when they’re ready to convert.
That’s why tools like Warmly, Koala, Clay, and Keyplay are being widely adopted by modern GTM teams.

3. Suitability for your target audience
Different lead enrichment software provides different data types, which can be relevant if you’re focused on a highly specific vertical.
Make sure that the platform you choose is specialized for the exact industry your target market is in or that it is versatile enough to cover different verticals, data types, and use cases.
For example, Dealfront is recognized as a reliable data enrichment tool for the EU, but struggles with US-based records.
4. Range of features and integration capabilities
Chances are you’ll need separate tools for sales engagement, website traffic identification, buying intent signal detection, sales engagement, etc.
Your lead enrichment solution needs to fit in that mix. Try finding a solution that provides broader core functionalities and can easily be integrated into your existing GTM stack.
And now, let’s see which data enrichment platforms made it to our top 9 list ⤵️

1. Warmly

Warmly is a revenue orchestration platform built for users looking to make the most of their website’s hidden potential.
It identifies website visitors, enriches them with granular intent data, and provides options for converting them on the spot.
Feature #1: Website traffic deanonymization
Knowing who’s visiting your website can significantly improve lead generation and boost your sales efforts by pointing your sales reps toward potentially hot leads.
Warmly reveals website visitors in real time, letting you drive more revenue from your existing web traffic.
However, the platform comes with a nifty trick up its sleeve.
Unlike most website traffic tracking software, it identifies both company and individual-level visitors with high accuracy rates, often allowing you to capture the exact person surfing your website right now.

The whole process is very easy, too, meaning you don’t have to be a tech genius to start identifying anonymous website visitors.
All it takes is pasting a snippet of Warmly’s code into your website, and you’ll start revealing companies and people surfing your website right now.
Tip: The snippet can also be added to your email campaigns. That way, you’ll know which leads came through a specific campaign, allowing for easier attribution and creating a tailored lead nurturing strategy.
But it doesn’t end there.
Warmly enriches each identified visitor with in-depth intelligence, as we’ll explain below.
Feature #2: Record enrichment
Once Warmly reveals the individuals and companies surfing your website, it creates new records in your CRM or enriches existing ones with the data it uncovered, such as:
- Firmographic data (job titles, email addresses, company names and addresses, phone numbers, and other company details.).
- Technographic data (software tools and technology a business uses).
- CRM data (ongoing and closed deals, account owners, previous interactions with your reps, etc.).
- SEP data (engagement with email campaigns, chatbot interactions, etc.).
- And more.

As a result, your CRM data will always be fresh, clean, and accurate, eliminating the need for manual record entries and corrections.
Feature #3: Intent enrichment
In addition to identifying website visitors, Warmly provides options for tracking their website sessions.
This gives you access to first-party intent data on each revealed lead, as their interactions with your website can clearly indicate whether they’re interested in your solution and how much.
This data includes:
- Pages visited on your website.
- Time spent on each.
- Downloaded content, etc.

It’s important to note that, unlike most other data enrichment platforms that provide only one type of intent data, Warmly also offers third-party intent data.
Thanks to its deep integrations with comprehensive data solutions such as Bombora, 6Sense, Clearbit, etc., the platform lets you reveal:
- Topics your leads recently searched for on the web.
- Whether they visited competitors’ websites.
- Job posts that can provide insights into what projects are a priority at a certain company, which operational challenges they face, etc.
- Job change data, allowing you to automate the following processes (e.g., update the CRM with new data, add them to new advertising sequences, etc.) and ensure you won’t lose a high-performing client or warm lead.
Why should you care about intent data?
Intent data is important for several reasons.
It allows you to:
- Immediately recognize website visitors who fit into your Ideal Customer Profile and focus on them from the start.
- Identify the hottest leads on the brink of conversion and have your sales reps engage them while their interest is at its peak.
- Create hyper-personalized, highly-targeted prospecting and sales outreach strategies based on the intel Warmly delivered.
- Provide optimal customer experiences by creating a tailored approach for each lead.
- Qualify and score leads with precision and accuracy.

Using a combination of first- and third-party intent data lets you create a 360-degree view of every lead’s readiness to buy.
This means sales professionals won’t have to wander in the dark anymore, struggling to single out high-value leads and find the best approach.
Instead, they can concentrate on what matters most—engaging and converting hot leads.
