The sales orchestration solution helps teams identify high-intent prospects, personalize outreach, and automate workflows.

However, some enterprise-grade customers of the tool are not happy with its outdated contact information, limited CRM integrations, and how complicated the platform can be to manage daily.

In other words, industry challengers are tired of paying top dollar for a platform that comes with redundant prospect data and can not even natively integrate with their CRM.

In this guide, I’ll cover the 10 best ZoomInfo alternatives in 2025 for enterprises that will help you identify accounts and then automatically reach out to them via email, AI chat, or even right there on your website with a video call.

TL;DR

Warmly offers the best alternative to ZoomInfo for enterprises with its real-time contact-level visitor identification, signal-based outreach, and live engagement capabilities like AI chatbot and video calls.
Intent-driven tools like RB2B and Bombora are ideal for identifying high-value accounts and acting on buying signals early.
On the other hand, there are tools like Koala and 6sense that can help you pair website intent with automated sales workflows to prioritize and convert leads.

Before we begin, I’d like to go over some of the main reasons why some enterprises have been looking to switch from ZoomInfo: ⤵️

Why are enterprise users looking to switch from ZoomInfo?

The main reasons why enterprises have been looking to switch from ZoomInfo include its outdated database of prospect info, limited native CRM integrations, and how complex the platform can be to manage, as if it’s a job by itself.

But don’t get us wrong here, we’re not trying to claim that ZoomInfo is a bad platform that enterprises need to avoid at all costs.

In fact, dozens of enterprise users are happy with the platform’s combination of a massive B2B database with a comprehensive range of sales management features.

Despite this, some users have been dissatisfied with the visitor identification software for several reasons:

#1: Contact information can overlap or be redundant

The #1 issue of ZoomInfo for enterprises has been its contact database, which can come with overlapping or inaccurate information.

A verified enterprise user of the platform mentions that leads can show up with different titles or outdated details.

‘’Overlap and redundancy in contact information is something which could be improved. Sometimes the same lead shows up with slightly different titles or outdated details.’’ – G2 Review.

#2: Limited CRM integrations

Next up, users of ZoomInfo are not happy with its limited CRM integrations, as some users claim that the platform needs to add more CRM apps to its library of integrations for companies using more niche platforms.

‘’CRM Integration is still weak and needs to add more CRM Apps, as many companies use different CRMs.’’ – G2 Review.

#3: The platform can be complicated to manage

Last but not least, users of the platform are not happy with how complicated the platform is to manage on a daily basis, with its sea of features ranging from Workflows to Websights.

Even though users appreciate having everything in one place, the platform can seem crowded and using certain features can be a nightmare at times.

‘’The tool itself can be a bit difficult to manage with multiple features from Workflows, Websights, formcomplete, etc. Nice to have everything in one place, but things can often seem crowded. Also, Advanced searches can be a nightmare at times.’’ – G2 Review.

#1: Warmly

Warmly offers the best ZoomInfo alternative for enterprises on the market with our signal-based revenue orchestration solution.

Behind this definition stands a simple yet powerful lead generation and conversion machine, as Warmly:

Picks up the buyer intent signals your prospects drop off on your channels and across the Internet.
Translates them into actionable insights to help you understand who your hottest leads are right now.
Leverages those signals and insights to orchestrate comprehensive outreach workflows.

Let’s get a closer look at some of the features that make Warmly an attractive solution for industry challengers:

Feature #1: Identifies your website visitors to the contact level

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

You add a snippet of Warmly’s code to your website, and the platform will start revealing leads in minutes.

In addition to essential company and individual-level identification, Warmly will also enrich each visitor’s:

Contact data (email address, phone number, social media profiles, etc.).
Firmographics (company location, size, funding, etc.).
Demographics (individual names, job positions, etc.).
Technographics (tools and software a company utilizes).

Warmly optimizes our data through a waterfall approach, which means we use multiple data providers (20+), including 2 other leading website de-anonymization providers (Vector and RB2B) to validate the accuracy, quality & overall match rate of our signal & contact data.

This leads to:

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

💡 To maintain the robust 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, ensuring that both contact-level and company-level data meet the high standards our customers expect.

Feature #2: Reveals your warmest leads based on intent data

I understand that knowing who your leads are is only one part of successful outreach and conversion.

This is why our software collects intent data for each lead, allowing you to understand who your hottest leads are right now.

The platform captures three types of intent signals:

First-party intent, which includes intent signals, leads left in your channels (website, app, etc.), such as website visits, the specific pages they visited, time spent on high-intent pages, recurring visits, etc.
Second-party signals, which come from monitoring LinkedIn for things like job change intent, new funding rounds, etc.
Third-party intent, including web searches that include keywords relevant to your product, visits to competitors’ websites or interactions with their ads, etc.

As a result, your sales reps will get:

A complete overview of which of your leads are most likely to convert right now.
Critical insights into each lead, which they can leverage to tailor their outreach strategies accordingly.

💡 What’s more, your organization will be able to deliver personalized pop‑ups that feel helpful, not intrusive, such as a custom piece of content, a relevant case study, or a direct link to book time with your team.

We call these high-converting pop-ups Warm Offers because we knew that both SDRs and users are tired of one-size-fits-all generic CTAs.

Warmly identifies visitors by company, behavior, and intent and then dynamically personalizes the pop-up content based on their buyer journey.

Feature #3: Signal-based sales orchestration

I understand that regardless of how good and alert your sales reps are, some prospects always fall through the cracks.

Warmly handles this by enabling you to automate essential outreach workflows, ensuring you’ll never miss a high-value opportunity again.

Firstly, there’s the Orchestrator, which enables you to set up automated email and LinkedIn outreach sequences by:

Specifying the trigger that sets the sequence in motion (e.g., a visitor matching your ICP lands on your website).
Defining the criteria the visitor needs to meet to be targeted (company size, industry, individual’s job role, etc.).
Specifying the frequency at which you want the workflows to run and the maximum number of people targeted in a single account.
Deciding on the action you want the Orchestrator to take (send contextual email and/or personalized LinkedIn DM or connection request).

Secondly, AI Chat, Warmly’s AI-powered chatbot, automatically engages and qualifies leads, offers collaterals, answers questions, and books meetings while ensuring that every interaction with every lead is contextual and tailored to their prior interactions.

You can try it out: 👇

Finally, Warmly lets you automate lead routing, as your reps will be notified in Slack the second a high-intent lead or visitor matching your ICP lands on your website.

Feature #4: A B2B Prospect Database: Coldly

Warmly comes with Coldly, a database with 200M+ accounts and contacts, which gives your sales team an excellent starting point for prospecting.

Coldly includes all the B2B data your sales reps need to make initial contact, including:

Validated emails.
Phone numbers.
LinkedIn profiles.

Our database also provides 25+ B2B filters and customizable data filters that you can set up, enabling your sales team to build highly targeted prospect lists in a few seconds.

Coldly also has a browser extension that lets you scrape essential B2B contact data from any source on the web, including LinkedIn profiles, company websites, etc.

You will have both accurate contact data and the right tools to pick up buyer intent signals and set up workflows on top of them.

Feature #5: Live video chat

Warmly enables your sales reps to engage leads directly via on-site live video chat.

Your team can do what they do best - engage high-quality leads while they’re still hot and nurture them into conversion.

If you go to the “Warm Call” section of the platform’s dashboard, you’ll see all the companies and individuals visiting your website right now, in addition to intent and B2B data on each visitor.

💡 When sales reps assess the time is right, or receive a Slack notification that a high-value lead has landed on your website, they can initiate a video call or send a contextual message in the text chat, emphasizing that they’re an actual human.

Reps can then leverage the data Warmly revealed to further nurture, warm up, and convert leads.
