Top 10 6sense Alternatives for Enterprises In 2025

The ABM platform’s website deanonymization solution helps you identify anonymous website visitors by matching their IP addresses and behavior data with its intent database.

However, some enterprise-grade customers of the platform are not happy with its outdated prospect info, duplicate records, and the fact that they cannot track intent down to the contact level to refine their messaging.

In other words, industry challengers are tired of shooting in the dark while paying top dollar.

In this guide, I’ll cover the 10 best 6sense alternatives in 2025 for enterprises that will help you identify accounts (some of them also offer contact-level data) and then reach out to them.

TL;DR

Warmly offers the best alternative to 6sense for enterprises with its real-time contact-level visitor identification, signal-based outreach, and live engagement capabilities like AI chatbot and video calls.
All-in-one sales tools like ZoomInfo and Lead Forensics are ideal for enterprises seeking large B2B databases paired with visitor identification and sales automation.
On the other hand, there are tools like Bombora and Demandbase that can help you strengthen ABM campaigns through advanced intent tracking, ad targeting, and account-based personalization.

Before we start, I want to go over some of the main reasons why some enterprise teams have been looking to switch from 6sense: ⤵️

Why have some enterprises been considering switching from 6sense in 2025?

The main reasons why enterprises have been looking to switch from 6sense include its outdated database of prospect info, the fact that sales reps have to deal with duplicate records and existing customers, and that 6sense is not capable of tracking contact-level intent.

But don’t get me wrong here, I’m not trying to claim that 6sense is a bad platform that enterprises need to run from.

In fact, there are dozens of enterprise users who are happy with the platform’s depth of features, integrations with sales platforms and CRMs, and how well it lets them align their team with marketing.

However, some customers have been dissatisfied with the sales intelligence platform for several reasons:

#1: Outdated prospect info

The #1 complaint from enterprise customers about 6sense has been about its outdated prospect info.

The thing about outdated prospect information is that it feels like you’re late to a party. The once ‘’in-market’’ accounts have either chosen a solution already, or the prospect has already switched jobs.

What that means for SDRs is that they have to start verifying the information in other platforms, such as LinkedIn and Apollo, spending time they could have otherwise spent selling.

‘’That said, in my segment, the info was outdated more often than not. I frequently hit stale titles, departed contacts, or reassigned direct dials—especially at fast‑growing companies. Even intent signals sometimes lagged, so “in‑market” accounts had cooled by the time I reached out.’’ – G2 Review.

#2: Full of duplicate records and existing customers

Next up, a verified enterprise user of the solution mentions that their team are unhappy with how many duplicate records there are inside 6sense’s platform.

On top of that, they’re not happy with how the platform cannot differentiate between a hot lead and an existing customer due to the platform’s poor integration with their Salesforce instance.

‘’I find that a majority of the accounts listed as hot are existing customers. As someone who only deals with net new accounts, I would love to be able to see an accurate list of only non-customers. It makes sense that a current customer would be looking up info on our company, I just want to be able to see prospects. I think if it were integrated better with our Salesforce instance, I would be far more inclined to recommend it to someone. It's full of duplicate records and existing customers.’’ – G2 Review.

#3: Cannot track intent down to the contact level

Last but not least, enterprise users wish the platform could track intent down to the contact level (i.e., you know that Josh from Oracle is looking for a solution, not Oracle).

➡️ There are platforms on the market (hint: Warmly) that can help you identify buyer intent at the contact level and not only at the account level.

‘’It's also frustrating that we cannot track intent down to the specific contact.’’ – G2 Review.

#1: Warmly

Warmly offers the best 6sense 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 web.
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

Unlike 6sense, 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: Multiple sources expand 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 hottest leads based on intent data

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

This is why our platform 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 team 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.

Warmly’s Integrations

Warmly integrates with a wide range of platforms, including:

OpenAI.

Pricing

Warmly’s pricing is modular and component-based.

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

There are 3 paid product plans that you can choose from:

AI Data Agent (Starts at $10,100/yr), which includes 5,000 credits, person-level web visitor de-anonymization (RB2B + Vector data), CRM integration, and access to our Coldly Contact Database.

How does Warmly compare to 6sense for enterprises?

Here are some of the key points to keep in mind when comparing Warmly to 6sense:

1. Intent Data Granularity

Warmly: Tracks 1st, 2nd, and 3rd-party intent (website visits, LinkedIn job changes, competitor research) to identify real-time buyer signals.
6sense: Provides account-level intent aggregated across multiple channels, indicating which accounts are in-market.

2. Account Scoring & Prioritization

Warmly: The world’s most intelligent TAM list builder that combines real-time signals, AI-powered enrichment, and automated orchestration to replace $1.8M/year in manual GTM operations.
6sense: Uses AI-driven propensity and predictive analytics to prioritize accounts (not contacts) most likely to convert.

3. Integrations

5. Pricing & Plans

Warmly: Starts at $10,100/year (AI Data Agent); higher tiers (Inbound/Outbound Agent) range from $18,000–$24,000/year; modular options available.

➡️ Warmly is better for enterprises looking for individual-level insights, streamlined personalization, and transparent, modular pricing, especially valuable for teams needing direct contact data and automated outreach.

Our platform is also compliant with all data privacy and security needs that an enterprise requires.

➡️ 6sense, on the other hand, shines in AI-powered account scoring, broad intent coverage, and deep ABM-focused analytics, but comes with higher costs, duplicate records, account-level data only, and often outdated prospect info.

✅ Enriches each identified lead with detailed B2B intelligence and reveals intent data.

✅ Best-in-class sales orchestration options.

✅ Live sales engagement capabilities.
