Overview

A JavaScript tracker on a business website identifies visiting companies and shows what they viewed and when. Leadfeeder combines that activity with company and people search, account lists, buying-intent signals, workflows, and AI features. The breadth makes it more than a visitor counter, but company identification is not the same as knowing which individual visited.

Connections include native CRM integrations, Slack, Google Ads, analytics tools, and more than 5,000 apps through Zapier. HubSpot, Salesforce, and Pipedrive support two-way CRM sync, a practical fit for teams that need visitor activity to flow into existing sales records. The Connect browser extension provides company and contact details in Chrome and Microsoft 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. Founded in 2012, the company lists Helsinki among its offices.

Key features

Visitor identification and account research

The tracker connects company visits with pages viewed and timing, helping sales teams prioritize accounts showing interest. Company search and account lists extend that signal into prospect research. This is most useful when a team can follow up at the account level; it is less suited to workflows that depend on identifying every individual visitor.

Signals, enrichment, and workflow

Buying-intent signals, people search, phone numbers, email finding, and AI prospect lists support movement from an identified company toward a contact and a sales action. Activate adds verified emails and phones, intent signals, B2B display campaigns, CRM automations, and AI prospect lists. These are meaningful additions for teams actively running outbound and nurture workflows, rather than necessities for those only measuring which companies visit.

Integrations and support

Two-way sync with HubSpot, Salesforce, and Pipedrive can reduce the gap between website activity and CRM records. Zapier's broad app connections offer flexibility beyond the named native integrations. Paid plans include live chat; Discover and Activate also include a shared customer success team, while Scale assigns a dedicated customer success manager.

Pricing

Leadfeeder is freemium, with paid plans starting at €79/mo (annual) and a 14-day trial. The annual billing condition matters: the displayed monthly starting price is not a month-to-month commitment.

Plan	Price and terms	What it means
Lite	0.00 EUR per free; free forever	Unlimited users, 7 days of visitor history, and up to 100 identified companies/month. It omits page-level visit detail, full company profiles, alerts, filters and saved lists, CSV export, and CRM integrations, so it works as a limited introduction rather than a full sales workflow.
Discover	79.00 EUR per month; billed annually; starting price	Company identification limits are tiered. This is the entry paid option for teams ready to move beyond Lite, though its tiered identification volume should be matched to expected traffic.
Activate	369.00 EUR per month; billed annually; starting price	Adds verified contact details, intent signals, display campaigns, CRM automations, and AI prospect lists. It fits teams that need to operationalize visitor signals, not just research accounts.
Scale	599.00 EUR per month; billed annually only; starting price	Includes unlimited data exports, automatic CRM data updates, and a dedicated customer success manager. The higher commitment is for teams where export volume, CRM upkeep, and dedicated support matter.
Enterprise	Custom pricing	Custom company identification and credit volumes suit needs that do not fit the stated tier structure.

The free plan's seven-day history and 100-company monthly cap make it hard to use for sustained pipeline work, and the missing CRM connection removes a central handoff. Paid plans include live chat support. Leadfeeder also states a 50 credits/mo allowance; teams weighing contact discovery should account for that alongside the plan's company identification limits.

Platforms

Leadfeeder is available as a web product, API, and browser extension. The extension supports Chrome and Edge, while the JavaScript tracker is installed on the website being monitored.

Who it's for

Leadfeeder is a strong fit for B2B revenue teams with meaningful website traffic, an existing CRM, and a process for following up on account-level intent. It is less compelling for teams that only need lightweight visitor counts, require individual-level visitor identification, or want a fully usable CRM-connected workflow without a paid plan.

Pros and cons

Pros: Combines company visits, account and people research, intent, and workflow tools, so a team can connect interest to follow-up without treating each as a separate task.
Pros: Two-way sync with HubSpot, Salesforce, and Pipedrive connects visitor activity to established CRM records.
Pros: Scale's unlimited exports and automatic CRM updates address ongoing data movement for larger teams.
Cons: Lite limits history to seven days and 100 identified companies per month while withholding visit detail, alerts, exports, and CRM integration.
Cons: The paid starting prices are annual-billed, and higher tiers rise substantially, making the richer prospecting workflow a meaningful budget decision.
Cons: Company-level identification alone will not satisfy teams whose process requires knowing which individual visited.

Alternatives

Choose Nalloo if a free plan with 50 monthly identifications, firmographics, and a full dashboard is enough; its free plan has no credit-card requirement, while Leadfeeder's Lite allows up to 100 identified companies but has a shorter history and fewer tools. RB2B is a free alternative for company-level identification with Slack push and 150 monthly resolutions, but its free tier excludes person-level ID, email addresses, and other integrations. Warmly offers a free API/MCP plan with 250 credits per month for teams that prefer that credit-based entry point.

Factors.ai is an alternative to consider if its Basic plan's stated 10,000 monthly tracked users, up to 3,000 identified companies per month, and five seats fit the team's scale. Snitcher suits teams seeking a paid company-ID tier with unlimited team members, starting at 49.00 USD per month for 0–50 unique company IDs. Albacross is worth comparing when verified contact credits and a browser extension are priorities; its Starter plan is 84.00 EUR per month and includes 10 verified email credits and 5 verified phone credits.

Avina is another paid option, with a Starter plan at 259.00 USD per month and up to 800 credits per month for signal-led workflows. Happierleads offers a white-label option priced per lead, which may suit teams evaluating that model.

Verdict

Choose Leadfeeder if your B2B team wants to turn company visits into researched accounts and CRM-linked follow-up, with deeper intent and automation available as it grows. Its strongest case is the connected path from visitor signal to sales workflow; its clearest drawback is that the free plan withholds the details and integrations that make that path useful. Look elsewhere if person-level identification is essential or annual paid pricing is not justified by your traffic and sales process.
