Top 10 6sense Alternatives for Marketing Agencies In 2025

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

However, some customers of the platform are not satisfied with its data syncs and inaccuracies, inconsistent reporting that’s hard to customize, and lack of explainability on how their models and scoring works.

In this guide, I’ll cover the 10 best 6sense alternatives in 2025 for marketing agencies 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 marketing agencies with its real-time contact-level visitor identification, signal-based outreach, and automated ad targeting.
Salespanel and Dealfront are ideal for agencies that need precise lead qualification or GDPR-compliant B2B data.
On the other hand, tools like ZoomInfo and Factors AI can help you centralize ABM processes and perform advanced multi-touch attribution.

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

Why are some marketing agencies looking to switch from 6sense?

The short version: many agencies love 6sense for its intent signals and ABM workflows, but its often inaccurate data, lack of explainability on buyer scores, and time-consuming reporting are pushing some agencies to consider alternatives.

I’m not saying 6sense is a bad product. Plenty of teams praise its intent data, predictive scoring, ad sync and orchestration, and white-glove onboarding.

But agencies have some specific needs (fast client reporting, multi-brand management, many small campaigns running in parallel) — and the reviews show a handful of consistent frictions.

Below are the main reasons marketing agencies tend to look elsewhere, with real G2 review lines pulled from users working in marketing and paid media.

#1: Data syncs, accuracy and integration quirks

The #1 called out issue from marketing leaders has been data discrepancies between 6sense and CRM/MAP systems, defaults that disrupt geographic targeting, or sync delays that require extra troubleshooting.

As agencies run multi-channel campaigns that depend on precise segmentation and timely syncs, misaligned data can waste ad spend and break client SLAs.

‘’Occasionally, data discrepancies appear between 6sense and our CRM, which can cause confusion.’’ – G2 Review.

#2: Reporting is either inconsistent, hard to customize, or time-consuming

A lot of marketers call out reporting as the weakest operational area, from unreliable marketing-influence outputs to rigid/custom reports that take effort to build.

I understand that agencies need fast, repeatable client reporting and clear attribution to demonstrate value. When reports need heavy customization or frequent troubleshooting, client confidence suffers.

‘’The reporting capabilities, particularly around marketing influence and 6sense-driven impact, are not reliable enough for actionable use. More robust and accurate reporting would greatly improve collaboration with sales teams.’’ – G2 Review.

#3: Lack of explainability on models and scores

Marketing agencies that use 6sense are looking for more transparency around how predictive scores or buyer-stage predictions are calculated, especially for niche verticals.

Clients would often ask “why” a lead or account is prioritized. If scoring looks mysterious, your agency must spend time justifying recommendations.

‘’The buyer stage predictions are extremely valuable, but at times they can be off for niche industries or very small target segments. More transparency into how those stages are calculated would help us fine-tune our targeting.’’ – G2 Review.

#1: Warmly

Warmly offers the best 6sense alternative for marketing agencies on the market with our signal-based revenue orchestration platform.

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

Picks up buyer intent signals your leads 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 marketing leaders:

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

Unlike 6sense, Warmly lets your team maximize your client’s lead generation potential by identifying both the companies and individuals visiting it.

The way it works is that you can add a snippet of Warmly’s code to your clients’ 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).

This will give you a more comprehensive idea of your clients’ leads, where they’re coming from, and how well they match the ICP.

Moreover, Warmly’s code snippet can be added to event pages or email campaigns, allowing you to capture leads across your owned channels.

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 Warmly 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 team 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.

Feature #3: Signal-based sales orchestration

We know that regardless of how good and alert your clients’ sales reps are, some warm leads 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.

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: Signal-based ad targeting

Warmly also lets you leverage onsite and offsite signals (e.g., LinkedIn engagement) to create highly targeted custom ad audiences for your clients.

For example, using Bombora intent data and Warmly’s Orchestrator, you can detect when companies are researching your competitors, integration partners, or relevant keywords.

Warmly then syncs those companies to LinkedIn Ad audiences, triggering campaigns that speak directly to what those prospects are actively exploring.

Warmly’s DemandGen AI agent does the same, but at a higher level.

Our AI agent uses all three types of intent signals to detect high-value opportunities, including them instantly in paid social campaigns across LinkedIn, Google Ads, Facebook, etc.

The result?

A constantly refreshed audience of in-market accounts sees highly relevant ads on all the channels they live in, while your competitors are still guessing.

It’s a scalable, automated way to increase awareness, warm up your ICP, and capture mindshare early in the buying journey.

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.
AI Inbound Agent (Starts at $18,000/yr), which includes all AI Data Agent features, 10,000 credits, Intent-powered pop-ups (Warm Offers), AI chatbot & live video chat, and lead routing.

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

➡️ If your agency’s priority is person-level visitor identification + quick snippet setup + built-in outbound automation (email / LinkedIn) and modular pricing for multiple client profiles — Warmly is positioned as a stronger fit.

💡 Agencies typically choose us over tools like 6sense because our platform offers the best data. Our platform gives marketers smarter, more targeted lists of people and accounts that are most likely to become leads, opportunities, and customers.

This also raises the ROI of their campaigns by giving them the tools to de-anonymize and convert high-intent site visitors with AI chat, and multi-channel automated nurture campaigns (a process our team calls warmbounding).

➡️ However, if your agency needs deep account-level predictive models, large-scale ABM orchestration across an enterprise MarTech stack, and advanced buying-stage modeling, 6sense is widely recognized for those strengths (but it’s typically sold with enterprise pricing and bigger onboarding effort).
