Company profile
researched Aug 2026Leadfeeder is a B2B lead generation and website visitor identification platform. A tracker script installed on a customer's website matches anonymous traffic to companies using an IP-to-company database, then enriches those companies with firmographic and contact data so marketing and sales teams can see which accounts are engaging with their content and what pages they view. The company positions the product around the premise that only a small share of website visitors convert through forms, and that the remaining anonymous traffic can be surfaced as qualified accounts.
The product is organized around several modules: Web Visitors for identifying companies behind anonymous visits and reading buying intent from on-site behavior; Companies for defining an ideal customer profile and building campaign audiences using firmographic, behavioral and intent filters; Lists for enriching company and contact records and syncing qualified leads into a CRM; and Campaigns for B2B display advertising aimed at ICP-matched accounts. Additional capabilities include automatic lead scoring based on web activity, custom feeds and alerts segmented by industry, geography, employee count, web activity and custom properties, campaign and channel attribution for identified companies, AI-assisted enrichment and qualification, and an API that customers use to pull visit metadata into their own data warehouses. The company states its data set covers 60 million companies and 400 million verified contacts and emphasizes B2B data collected under European data privacy standards.
Leadfeeder was launched in 2014 by CEO Pekka Koskinen together with colleagues from his earlier web analytics company Snoobi, which was acquired by Fonecta in 2012. The company is headquartered in Helsinki, Finland, and operates with a distributed remote workforce; its founder profile also lists a base in Karlsruhe, Germany. Customer-facing material and reviews reference the Dealfront brand alongside Leadfeeder.
Founding story
Leadfeeder was launched in 2014 and founded by CEO Pekka Koskinen along with other key employees from his previous company, Snoobi, a web analytics tool widely used in Finland that was acquired by Fonecta in 2012. Koskinen framed the opportunity as a gap between web analytics and sales: while marketing had evolved toward marketing automation and remarketing, salespeople still had little visibility into how prospects and existing customers behaved online, and Leadfeeder set out to deliver that intelligence automatically into email and CRM systems. One source additionally names Herkko Kiljunen and Vicent Llongo as founders.
Business model
Subscription software sold to B2B companies, with a 14-day free trial that requires no credit card and paid plans thereafter. Customers install a tracking script and pay for ongoing access to visitor identification, company and contact data, enrichment and integrations.
Recurring SaaS subscriptions; the company reported over 400 monthly-paying customers in the period leading up to its 2016 seed round.
Traction
The company cites more than 15,000 customer companies, over 850 G2 reviews and over 500 million leads generated through the platform. Earlier disclosed traction included 300% revenue growth in 2015, over 2,500 active monthly users and over 400 monthly-paying customers at the time of its seed round. Published customer outcomes include a claim of €180k in previously hidden pipeline and 90% faster prospecting at Custobar, and a 34% increase in qualified sales leads at another customer.
Latest developments
Recent product messaging centers on AI: agentic-AI enrichment for lead qualification, an 'Ask Leadfeeder' conversational interface for querying site visitors and enrichment data, AI-driven sales-intelligence insights, and B2B display advertising campaigns targeted at ICP-matched companies. Customer reviews note that company identification coverage has improved over the past year and that recently added AI features expanded the tool's usefulness.

Market position
Positions itself as a provider of web visitor identification technology and B2B company data, claiming an industry-leading IP-to-company database and citing over 15,000 customer companies and more than 850 G2 reviews. Customer reviews describe it as comparing favorably with other website visitor tracking tools they had used.
Emphasizes the breadth of its IP-to-company matching, stating it can identify up to 45% of companies visiting a website and recognize the company IP regardless of the visitor's network, combined with European data-privacy-compliant B2B data collection, fast time-to-value (first identified companies within about four minutes of setup) and a documented API that lets customers build their own scoring on top of raw visit data.
Technology
A JavaScript tracker script on the customer's website feeds an IP-to-company matching database that resolves anonymous visits to company identities, which are then enriched from a database of 60 million companies and 400 million verified contacts. The system scores and prioritizes accounts on fit and intent, applies more than 100 filters plus AI/agentic enrichment for ICP definition, attributes identified companies to campaigns and channels, and exposes clean visit metadata (source, campaign, keyword, full landing-page query strings) through an API. Data flows out through native integrations with Salesforce, Pipedrive, Microsoft Dynamics, HubSpot, Zoho, Looker Studio, Gong and Google Ads.
Go-to-market
Product-led self-service entry via a 14-day free trial without a credit card, alongside booked demos for sales-assisted deals. Marketing relies on content such as go-to-market and lead-generation guides, customer stories, G2 reviews, and integration-driven distribution with CRM and analytics tools. Early growth was supported by its Google Analytics Partner status and press coverage in outlets including The Next Web, Computer Weekly, TechCrunch, Kissmetrics and Product Hunt.
B2B marketing and sales teams that want to convert existing website traffic into qualified pipeline, including revenue teams using CRM and marketing automation systems; referenced customers include Custobar and DNA.
Geography
Headquartered in Helsinki, Finland, serving customers internationally; the workforce is split between Helsinki and remote staff, and the founder profile lists Karlsruhe, Germany. Go-to-market content includes region-specific guidance such as a Benelux market guide.
History
The product launched in 2014 as a Google Analytics-integrated lead generation tool. Revenue grew 300% during 2015, and in early 2016 the company raised a €530k seed round from Superhero Capital and Vendep, which it earmarked for market expansion, tripling its Helsinki and remote workforce, and R&D on analytics-based sales automation. In April 2019 it raised a €3.1 million Series A led by Endeit Capital with Superhero Capital and Vendep Capital participating. The platform has since broadened from Google Analytics-linked visitor tracking into ICP audience building, B2B display advertising, contact enrichment and AI-assisted qualification.
Risks & controversies
Public reviews reference a subscription renewal and cancellation process that was mishandled in at least one case, which the company's VP of Customer Success subsequently resolved. The business depends on IP-to-company identification and B2B personal data, making it sensitive to data privacy regulation; the company markets GDPR-compliant strategies and European data collection standards in response.
