Overview

A JavaScript tracker identifies companies visiting a website and shows what they viewed and when, helping teams judge which accounts merit follow-up. Leadfeeder adds company and people search, account lists, intent signals, workflows, and AI features. The emphasis is on company-level activity, so it is a better fit for account-focused selling than for teams whose primary need is identifying individual visitors.

Native CRM integrations connect with existing sales workflows, and HubSpot, Salesforce, and Pipedrive support two-way sync. Leadfeeder also integrates with Slack, Google Ads, analytics tools, and more than 5,000 apps through Zapier. Its Connect extension surfaces company and contact details in Chrome and Edge.

Leadfeeder says its security and privacy programs are based on ISO 27001 and ISO 27701, encrypts customer data in transit and at rest, and hosts its AWS infrastructure in the EU/EEA. The company was founded in 2012 and lists Helsinki among its offices.

Key features

Visitor identification and research

Company visits, page views, and timing give sales teams a basis for prioritizing outreach rather than treating every account alike. Company search and account lists extend that research, while intent signals can help surface buying interest. The free Lite tier omits page-level visit detail, full company profiles, alerts, filters, and saved lists, limiting how deeply teams can investigate or organize activity without upgrading.

Prospecting and CRM workflow

Activate adds verified email addresses and phone numbers, intent signals, B2B display campaigns, CRM automations, and AI prospect lists. Two-way sync with HubSpot, Salesforce, and Pipedrive can keep prospecting activity connected to sales records. Paid plans include live chat; Discover and Activate include a shared customer success team, while Scale provides a dedicated manager.

Pricing

Leadfeeder uses a freemium model, with a 14-day trial and annual billing for its published paid starting prices. Company identification limits are tiered on paid plans, so the starting price is not a universal volume allowance.

Lite: 0.00 EUR per free, free forever. It allows unlimited users, seven days of visitor history, and up to 100 identified companies per month. That makes it a low-commitment way to check whether company identification is useful, but the missing visit detail, profiles, alerts, filters, saved lists, CSV export, and CRM integrations make it a poor fit for a team relying on ongoing sales workflows.
Discover: 79.00 EUR per month, billed annually, starting price. It is the entry paid option for teams that need more than the capped free tier; identification volume is tiered.
Activate: 369.00 EUR per month, billed annually, starting price. Verified emails and phones, intent signals, campaigns, CRM automations, and AI prospect lists make it the more relevant choice for teams that want to turn visitor activity into active prospecting.
Scale: 599.00 EUR per month, billed annually only, starting price. Unlimited data exports, automatic CRM data updates, and a dedicated customer success manager suit larger or more operationally demanding teams.
Enterprise: Custom pricing, with custom company identification and credit volumes for organizations needing negotiated capacity.

Lite's 100-company monthly cap and seven-day history are the main constraints for evaluating sustained activity. Paid plans include live chat, but the listed starting prices are annual-billing rates rather than month-to-month terms.

Platforms

Leadfeeder is available on the web and through an API and browser extension. The Connect extension supports Google Chrome and Microsoft Edge.

Who it's for

Leadfeeder is strongest for B2B revenue teams that want to spot companies engaging with their website, research accounts, and connect follow-up to a CRM. Lite can suit a small team validating the approach, while Activate or Scale is more compelling when verified contact details, automation, exports, or dedicated customer support matter. It is less suitable for teams that need a generous free tier or whose core use case depends on individual visitor identification.

Pros and cons

Pro: Website activity is paired with company search and intent signals, giving account-focused teams context for prioritizing outreach.
Pro: Two-way sync with HubSpot, Salesforce, and Pipedrive can tie visitor-driven follow-up to established CRM records.
Pro: Activate and Scale add concrete sales operations capabilities, including verified contact details, CRM automation, exports, and customer success support.
Con: Lite's 100-company monthly limit and seven-day history constrain longer-term evaluation, and several useful research and workflow tools are excluded.
Con: Paid starting prices are tied to annual billing, and higher tiers rise substantially from Discover's €79.00 monthly starting price.
Con: Company identification volume is tiered on paid plans, so buyers should match their expected traffic to the appropriate allowance.

Alternatives

Consider these options if their free limits, delivery model, or pricing better match your prospecting needs:

Leadberry is another freemium, web-based B2B lead-generation option with a free plan and trial.

Ploy may suit teams seeking a web-based free plan with 500 credits per day, capped at 2,000.

Verdict

Choose Leadfeeder if your B2B team wants to turn company website engagement into researched, CRM-connected follow-up; its strongest case is the path from visit signals to prospecting workflows. Look elsewhere if you need generous free history and volume, or if individual visitor identification is central to your process.
