10 Best LeadFuze Alternatives & Competitors [2026]

Even though LeadFuze has not disappeared completely, the platform has transitioned from direct software access to selling its data license.

The company now lets you focus on its data, which they refresh monthly, including hundreds of millions of profiles and 150m+ phone numbers.

Despite this, some users of the platform have not been happy with the tool’s customer service, contract negotiation practices, international data coverage, and upload limits.

In this article, I’ll go over the 10 best alternatives to LeadFuze in 2026, going over their core features, use cases, pros & cons, and pricing models.

TL;DR

Warmly offers the best alternative to LeadFuze with its signal-based revenue orchestration, person-level website de-anonymization & enrichment, and AI-SDR automated outreach capabilities.
Data-first tools like Cognism and ZoomInfo are ideal for global coverage, enterprise-grade compliance, and high-volume enrichment and scale.
On the other hand, there are tools like Apollo and MadKudu that can help you run affordable all-in-one prospecting and outbound automation and predictive lead scoring and smarter inbound routing.

Why have some sales teams been looking to make the switch from LeadFuze?

The main reasons some sales teams are looking to switch from LeadFuze are its poor customer support, contract negotiation practices with no option to cancel, limited international data coverage, and upload limits.

But don’t get me wrong here, I’m not trying to claim that LeadFuze is a terrible solution that you need to run from.

In fact, dozens of satisfied users are more than happy with its lead data in the US, affordable pricing model, and monthly data refreshes.

Despite this, there are a few reasons why some users have been looking for an alternative: ⤵️

#1: Poor customer service and contract negotiation practices with no option to cancel

Some users of LeadFuze have reported negative experiences regarding data quality and customer service, particularly with long-term contracts.

‘’The company specifically will try to tie you into a one-year contract. Do not sign the one-year contract because the leads are awful, and if they provided a month-to-month, then you would leave after the first month. The team will do nothing to make the situation right and will use contracts/terms of conditions instead of doing the right thing and refunding you. We asked to cancel our account after 5 months, and they first cancelled our account and then randomly sent the account to collections after 3 years.’’

At first, I thought that this was a standalone negative experience, but it turned out that multiple users have experienced LeadFuze’s poor customer support and contract negotiation & enforcement practices.

‘’Leadfuze uses deceptive tactics to lock you into a contract, then refuses to let you cancel and sends you to collections if you don't pay. What an awful way to deal with customers.’’ – G2 Review.

#2: Limited international data coverage

Next up, some users of the platform are not happy with LeadFuze’s international data coverage outside of the US.

This could mean that sellers focused on the EU or APAC markets are going to have a harder time building lead lists.

‘’Searching is easy, but results in other countries (except the US) are very limited.’’ – G2 Review.

#3: Upload limits

One major drawback of LeadFuze is that it only allows you to upload a small number of leads at a time, which can quickly become frustrating if you’re building larger prospect lists.

➡️ This limitation slows down workflows and makes the platform feel inefficient compared to competitors that support bulk uploads or seamless list management.

‘’They only allow you to upload a small number of people to your list at a time.’’ – G2 Review.

#1: Warmly

Warmly (that’s us) offers the best LeadFuze alternative with our signal-based revenue orchestration platform that helps you identify who your website visitors are at the person and account level and then automatically reach out to them.

Our sales intelligence solution uses person-level intent signals to identify and prioritize your best customers in real-time, so you can build your best list of prospects from intent data.

Disclosure: Despite the fact that Warmly is our AI sales software, I’ll look to provide an objective perspective on why Warmly is the best alternative to LeadFuze on the market.

Warmly offers a signal-based revenue orchestration solution that lets you:

Identify website visitors (~60% of companies and ~15% of contacts).
Reveal which website visitors are most likely to convert.
Gain unique insights into prospects so that your SDRs can tailor their strategies accordingly.

Let’s look at some of the capabilities that make Warmly the go-to option for GTM teams looking to switch from LeadFuze:

Feature #1: Identify your website visitors at the company and person level

Warmly lets you maximize your website’s lead generation potential by identifying both the companies and individuals visiting it.

All you have to do would be to add a snippet of Warmly’s code to your website, and the sales intelligence software will start revealing your visitors in minutes.

In addition to company and person-level identification, Warmly will also enrich your visitors’:

Contact data (e.g., email address, phone number, social media profiles, etc.).
Firmographics (e.g., company location, size, funding, etc.).
Demographics (e.g., individual names, job positions, etc.).
Technographics (e.g., tools a prospect uses).

But our visitor identification solution doesn’t stop there.

Warmly also tracks real-time 1st, 2nd, and 3rd-party intent signals to surface the visitors that matter most, so you can instantly prioritize outreach based on actual buying behavior.

That includes:

1st-party signals, such as pricing page views, repeated visits, product usage, or form fills.
2nd-party signals like relevant LinkedIn activity (e.g., industry-relevant discussions, posts, comments, likes, etc.).
3rd-party signals like competitor research or intent keywords being searched.

Warmly optimizes its data through a waterfall approach.

Our tool uses multiple data providers (20+), including 2 other leading website de-anonymization providers to validate the accuracy, quality & overall match rate of our signal & contact data.

We’ve seen that this leads to:

Higher data quantity: Multiple sources expand match rates.
Higher data quality: Proprietary cleansing and confidence scoring validate accuracy.

💡 To maintain data quality and quantity, we continuously monitor vendor performance and validate our proprietary matching algorithms.

➡️ These systems allow us to track quality and quantity metrics in real-time to make sure that both contact-level and company-level data meet the high standards our customers expect.

Warmly’s transparent data commitment means you can test our data quality with our free tier before committing to us as a data provider.

Since our platform aggregates data from 25+ providers and cross-checks it using our proprietary waterfall technique, the software can validate and verify data on your behalf, ensuring it’s of the highest quality.

Feature #2: Find prospects that look just like your best customers

Most sales intelligence tools on the market give you firmographic filters, such as industry, headcount, location, and job title, and call it a day.

However, our platform goes much deeper.

With our AI-powered ICP identification capabilities, Warmly analyzes your actual customer data to uncover what really makes a good fit.

And it’s not just surface-level attributes: it’s patterns across the company tech stack, growth signals, org structure, seniority distribution, and even past engagement behavior.

Once Warmly understands who your best customers truly are, it’ll automatically scan its database of 200M+ contacts to find lookalike prospects, that is, the people and companies that closely resemble your top performers.

The result is a list of not just any prospects, but the right prospects, so your team spends less time guessing and more time engaging the people most likely to convert.

Feature #3: Turn static lead lists into automated outreach with AI SDRs

Once you have built the list of prospects, Warmly doesn’t just let it sit there. It gets to work for you.

With AI Orchestrator and built-in AI SDR agents, Warmly turns every high-fit lead into a warm opportunity by triggering automated, personalized outbound across email and LinkedIn, based on real-time behavior and intent signals.

Here’s how it works:

Prospects who match your ICP and show strong signals (like visiting the pricing page or researching competitors) are instantly added to outbound sequences.
Messages are personalized automatically using contact data, context, and intent.

3. Warmly checks to avoid duplicate outreach and ensures contacts aren’t already being worked.

4. You can even set rules for account multithreading, so your AI SDR reaches all the key decision-makers, not just one person.

And this isn’t just task automation. It’s real prospecting, at scale, without increasing SDR headcount.

Feature #4: Marketing Ops Agent

The best GTM strategy is meaningless if you don’t have the right target list of companies and people.

This is why we launched the Marketing Ops Agent to help you build your best lead list.

It’s an easy-to-use platform that automatically builds and maintains real-time, up-to-date lists of your best-fit accounts and contacts, so your GTM team can focus on strategy and creativity instead of spreadsheets.

Here's how it works:

‎

The Marketing Ops Agent connects directly to your CRM, ad platforms, outbound tools, and intent sources to automate key targeting workflows:

AI-powered lead scoring and enrichment to create dynamic lists ranked by fit and buying intent.
Buying committee identification using insights from past closed-won deals.

Instant audience syncing with HubSpot, Marketo, LinkedIn, Meta, Outreach, and more. No more manual CSV uploads.
Automatic list updates as new intent signals or engagement changes occur.
Unified buying intent scores that stay synced across every sales and marketing channel.

Feature #5: Build targeted lead lists from a 200M+ contact database (Coldly)

Warmly offers a built-in prospecting platform, Coldly, which gives your team access to a constantly refreshed database of over 200 million contacts and accounts, so you can build high-quality prospect lists in seconds.

The database combines powerful filters with real-time enrichment to help you find exactly who you’re looking for across every channel.

You will be able to filter by:

Job title, function, or department.
Seniority level and decision-making role.
Company size, revenue, industry, or location.
Tech stack and hiring signals.
And dozens more customizable filters.

➡️ Each prospect comes pre-enriched with verified email addresses, phone numbers, and LinkedIn profiles, so your lists are not only accurate but also immediately actionable.

Bonus: There’s also a Chrome extension that lets your reps pull contact data directly from LinkedIn or any website, making manual prospecting a whole lot faster.

Warmly’s Integrations

Warmly integrates with a wide range of CRMs and sales platforms, including:

HubSpot CRM.
OpenAI.
Slack.
Apollo.
Outreach.
Demandbase.
RB2B.
Clearbit.
People Data Labs.
And more.

💡 For example, it’s possible to combine Warmly’s visitor identification software with HubSpot to alert your sales team the moment a known prospect arrives on the site.

With the HubSpot browser cookie, you can prioritize conversations with the leads who have shown the most engagement with your HubSpot campaigns.

In addition to deep integrations with several lead intelligence platforms, Warmly provides a Warm Bundle: partner discounts for over 25 sales, marketing, and GTM tools.

This way, your team can access many relevant tools and combine them with Warmly at a fraction of their usual price.

Pricing

Warmly’s pricing is modular and component-based and comes with a free plan that lets you identify up to 500 website visitors per month.

You can choose the components that best match the needs of your business, as components are priced by output and not just by a monthly fee.

There are 4 paid product plans that you can choose from:

AI Data Agent (Starts at $10,000/yr), which includes 10,000 credits, person-level web visitor de-anonymization (RB2B + Vector data), CRM integration, and access to our Coldly Contact Database.

Monthly credits on Warmly are used to track and engage with potential leads.

For example, each interaction or engagement with a lead will use up one credit, such as when you engage with a lead through email or LinkedIn.

➡️ Warmly’s pricing is ideal for larger SMB and MM companies with a growing or mature GTM motion with SDR, sales, and marketing functions.

How do Warmly’s credits work?

💡 Warmly provides you with a certain amount of credits every month, depending on your monthly web visits and the amount you want to de-anonymize.

Once someone visits your website, the tool captures their first and last name, job title and company they work at, LinkedIn profile and business or personal email. This information takes 1 credit.

For example, each interaction or engagement with a lead will use up one credit, such as when you engage with a lead through email or LinkedIn.

How is Warmly different from LeadFuze?

LeadFuze is built around a large, purpose-built B2B contact and company database plus list-building automation that helps teams find verified emails, build targeted prospect lists, and run outbound campaigns at scale.

Warmly, on the other hand, is a person-level website de-anonymization and intent platform focused on identifying the actual people and companies visiting your site.

The platform surfaces who’s in-market, and enables real-time engagement (routing, notifications, on-site chat, and automated SDR workflows) so reps can act while intent is highest.

➡️ Warmly is better than LeadFuze for GTM teams that need to instantly identify and engage in-market visitors on their website with real-time routing and sales orchestration.

Here’s a breakdown of the two solutions’ functionality:

Category	Warmly	LeadFuze
Core Functionality	Person-level website de-anonymization and intent detection that reveals contacts and companies visiting your site, ties them to accounts in your CRM, and prioritizes in-market prospects for immediate engagement and routing to reps.	Custom B2B data platform and enrichment engine that combines AI automation with human verification to produce high-precision contact and account data, custom extractors, APIs, and lookalike audiences for ABM and outbound.
Data Enrichment and Intent Signals	Combines first-party website behavior with enrichment to reveal which people and accounts are on your site and layers external signals to prioritize visitors by intent.

Best For	GTM teams that want to detect person-level intent on their website and immediately engage high-intent visitors with automated, real-time interactions and routing.	Sales and marketing teams that need high-quality, tailored B2B data, custom enrichment, lead list building, and behavioral or contact signal models to power ABM, outbound, and CRM enrichment at scale.

#2: Cognism

Best for: Global enterprises doing cross-border outbound looking for best-in-class lead enrichment.

Similar to: Apollo.

Cognism stood out to me with its combination of global B2B data with strong privacy, compliance controls and intent signals.

It’s a good enough LeadFuze alternative for international teams that need global data coverage plus enterprise-grade consent and compliance capabilities.
