I recently tested Leadfeeder, a B2B tool that turns anonymous website visitors into actionable leads. Here's my hands-on review. Leadfeeder shines by identifying companies on your site using IP tracking and machine learning. During my trial, setup was quick: just add a JavaScript snippet and connect Google Analytics. The dashboard showed real-time visits, company details, and intent signals clearly. I loved filtering high-value traffic and pushing leads to my CRM via Zapier. The free plan gives 100 companies monthly with 7-day retention, perfect for testing. Paid tiers from €99/mo scale by lead volume, offering unlimited data, API access, and team alerts. Integrations with HubSpot and Salesforce worked smoothly in my tests. Accuracy impressed me, though bot filtering occasionally missed noise. Pricing can rise fast for high-traffic sites. No desktop or mobile app, just web-based. Overall, Leadfeeder boosts sales pipelines effectively for SMBs. Great for marketing teams needing quick wins.
