Top 10 Leadfeeder Alternatives for Marketing Agencies In 2025

The platform helps agencies identify the companies already visiting their clients’ websites and convert them into high-value leads.

However, some users of the platform are not satisfied with the fact that it does not identify exactly who visited your website, its automation and integrations, and its data accuracy and coverage limitations.

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

TL;DR

Warmly offers the best alternative to Leadfeeder for marketing agencies with its real-time contact-level visitor identification, signal-based outreach, and automated ad targeting.
Tools like ZoomInfo and RB2B are ideal for agencies that need deep B2B databases or US-based visitor deanonymization with sales engagement integrations.
On the other hand, there are tools like Factors AI and Visitor Queue that can help you improve attribution tracking and website personalization for higher conversions.

Before we get started, I want us to go over some of the main reasons why some agencies have been looking to switch from Leadfeeder: ⤵️

Why have some marketing agencies been looking to make the switch from Leadfeeder?

Most agencies like Leadfeeder for the visibility it gives into company-level website visits, the easy HubSpot/Salesforce integrations, the clear visitor journey reports, and features like programmatic retargeting.

However, some teams are exploring alternatives because Leadfeeder doesn’t always meet agency-scale needs in a few important areas.

Below are the main reasons agencies are thinking about switching:

#1: It doesn’t identify who visited your website; contact-level signals are limited

Agencies that run outreach for multiple clients often need contact-level identification or easier ways to match a site visit to a decision-maker.

Reviewers repeatedly point out that Leadfeeder can identify the company but not the individual visitor:

➡️ That makes personalized outreach and account-based playbooks harder to execute at scale.

‘’It doesn't tell you exactly WHO visited the site, like the decisionmaker.’’ – G2 Review.

#2: Automation & integration friction for agency workflows

Agencies want automated workflows across multiple clients and CRMs.

Several reviewers said useful automations or tag/ follow-up workflows require higher-tier plans or manual effort, and some CRM integrations (or custom CRMs like Odoo) need extra technical work.

That slows down scale and adds overhead when an agency manages dozens of accounts.

‘’Also, while the HubSpot integration is helpful, some parts of the process—like tagging and tracking follow-ups—require manual effort unless you're on a higher plan with automation.’’ – G2 Review.

#3: Data accuracy & coverage limitations (IP-based limits, mislabels, remote work)

Several verified reviewers flagged limitations in company matching or coverage, such as mislabelled companies, gaps for remote workers (because identification relies heavily on IP), and occasionally outdated prospect details.

For agencies running many campaigns and needing high confidence in the data, these issues add extra manual verification work.

‘’The system sometimes mislabels companies, leading to incorrect results.’’ – G2 Review.

#1: Warmly

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

Behind this definition stands a 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 Leadfeeder, 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).

Next up, 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, our platform 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 annual plans available in Warmly’s pricing model:

Data Agent Plan: Starting at $10,000/year, which includes 10,000 monthly credits, person-level 1st party web visitor de-anonymization (via RB2B, Vector, etc.), all Warmly Signals with warm lead alerts via Slack or Teams, HubSpot & Salesforce integration, and 100+ other sales/marketing tech integrations.
Outbound Agent Plan: Starting at $14,600/year, which includes AI Data Agent (signals & enrichment), native LinkedIn and marketing outbound automation, ability to push leads to sales sequencers (Salesloft, Outreach, etc.) and ad audiences, domain warmup, and lead routing with custom CRM fields.
Inbound Agent Plan: Starting at $20,000/year, which includes AI Data Agent (signals & enrichment), Warm AI Chat with intent-powered chatbot & live video, Warm Offers (pop-ups) and Warm Calling (live video), and lead routing with custom CRM fields.

How does Warmly compare to Leadfeeder for marketing agencies?

Here are some of the key points to keep in mind when comparing Warmly to Leadfeeder as a marketing agency:

#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.
Leadfeeder: Focused on first-party website intent (anonymous IP → company mapping + known form fills). Strong at company-level behavioral signals and integrates with Google Analytics for page-level insights.

#2 Account Scoring & Prioritization

Warmly: Scores leads using signal-based criteria (ICP fit + multi-source intent) and instantly routes them to reps via Slack or CRM.
Leadfeeder: Provides lead scoring, custom filters & feeds to prioritize leads (50+ behavioral & firmographic filters). Automated alerts and feeds surface high-value accounts.

#3 Integrations

Warmly: Native connections to CRMs and common martech tools — CRM sync, Slack alerts, ad platform syncs, sequence automation, and LinkedIn/email actions. Modular setup allows adding orchestration and outreach.
Leadfeeder: Native integrations with Google Analytics, major CRMs, Slack, and marketing tools. Connector APIs built for exporting account lists and pushing leads into external systems.

#4 Personalization & Outreach

Warmly: Provides person-level visitor identification, AI Chat (for qualification, collateral delivery, meeting booking), and Orchestrator for automated email + LinkedIn sequences triggered by signals.
Leadfeeder: Emphasizes surfacing companies/visitors and pushing data to CRM/MA platforms. Limited native multi-channel outbound — mainly serves as an intel feeder into other outreach tools.

#5 Audience Building & Segmentation

Warmly: Builds real-time signal-based audiences from onsite + offsite data. DemandGen AI can refine audiences and sync them directly to ad platforms for in-market targeting.
Leadfeeder: Builds lists, custom feeds, and segments from page behavior and firmographics. Well-suited for ABM lists and monitoring target accounts.

#6 Campaign Automation & Orchestration

Warmly: Orchestrator + DemandGen AI triggers full-funnel plays (emails, LinkedIn DMs, chatbot engagement, Slack alerts). Automates lead routing and ad audience inclusion in a continuous signal → action loop.
Leadfeeder: Provides alerts, custom feeds, and data exports to trigger campaigns in external MA/CRM platforms. Less native orchestration, more of a “feed + integrate” model.

#7 Ad Targeting & Activation

Warmly: Signal-based ad audience builder — syncs companies to LinkedIn, Google, and Facebook. DemandGen AI automatically refreshes in-market audiences.
Leadfeeder: Exports account lists and audiences to ad platforms via integrations. Core strength lies in building lists from site behavior; activation handled externally.

#8 Pricing & Plans

Warmly: Starts at $10,000/year (AI Data Agent). Higher tiers: Outbound Agent $14,600/year; Inbound Agent $20,000/year. Modular add-ons available.

‍

➡️ 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.

💡 Marketing agencies typically choose us over tools like Leadfeeder 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).

➡️ Leadfeeder, on the other hand, provides a fast, affordable, and reliable website-to-account feeder. It’s ideal when a client wants lightweight account lists from web traffic, quick GA integration, and a low monthly entry price.
