Leadfeeder and Proof solve two different website problems. Leadfeeder uncovers which companies visit your site. Proof makes those visitors convert with personalized experiences. Your choice depends on whether you need better lead identification or better lead conversion.
Best for: B2B sales teams needing to identify companies visiting their website, Marketing teams wanting to see which companies engage with their campaigns
Best for: Startup marketers looking to increase website conversions., Growth teams wanting to personalize user experiences.
Advanced B2B Lead Identification, High Risk.
We found Leadfeeder offers powerful B2B visitor identification features, including robust filtering and unique remote employee recognition capabilities. However, we note consistent customer reports detailing unresolved CRM integration failures and problematic auto-renewal billing policies that undermine its fundamental value proposition. Overall, the powerful features are currently overshadowed by serious concerns regarding support responsiveness.
Solid personalization tool, but reviews missing.
We reviewed Proof as a website personalization platform aimed at boosting conversions. It offers clear features and structured pricing for growth-focused teams. Overall, we find it a promising tool for targeted marketing, but the lack of accessible user reviews makes it hard to fully validate its real-world performance and support.
Leadfeeder is a powerful tool designed to help salespeople, marketers, and agencies find hidden opportunities in their web traffic. Its unique technology scans incoming traffic and identifies the companies visiting your website based on their IP address. This works even if employees are working from home. Once identified, the tool helps you uncover exactly what those companies are interested in, confirming their true buying intent. This crucial data processing meets all necessary GDPR legislation requirements. ✅
Proof is a platform focused on website personalization. 🎯
It's designed for marketers and growth teams at startups and fast-growing companies. The idea is to move beyond a one-size-fits-all website. Instead, you can tailor content, offers, and messaging to different visitor segments. This can help you increase conversions and engage your audience more effectively.
We highlight the main differences and pick a winner for each feature.
Leadfeeder is a lead identification tool. Proof is a website personalization platform.
Leadfeeder scans website traffic and identifies visiting companies using IP addresses. It then provides contact information for decision-makers at those companies. Proof helps you change what visitors see on your website. You can tailor content, offers, and social proof notifications to different visitor segments. Leadfeeder answers 'who is visiting?' while Proof answers 'how do we convert them?'. They solve different parts of the sales funnel. If your main problem is not knowing which companies are interested, Leadfeeder is the tool. If your problem is low conversion rates from existing traffic, Proof is the solution.
Leadfeeder identifies companies. Proof uses personalization, not identification.
Leadfeeder uses a large IP database to identify the company behind a website visit. It claims the highest recognition rate, even for remote employees. You get firmographic data like company size and industry. Proof does not identify anonymous visitors. Its focus is on personalizing the experience for all visitors based on behavior or segments you define. This is the fundamental difference. Leadfeeder provides intelligence on *who* is on your site. Proof provides tools on *what* to show them. For sales teams needing to know which target accounts are researching them, Leadfeeder is essential. Proof doesn't provide this intelligence.
Proof is built to increase conversions. Leadfeeder is a lead feeder, not a converter.
Proof's entire platform is designed to boost website conversions. It offers social proof notifications, personalization, and A/B testing to optimize the user journey. Leadfeeder's goal is to identify and qualify leads for your sales team. It doesn't optimize the website experience itself to increase conversion rates. Proof can show a visitor that 50 others signed up today, creating urgency. Leadfeeder will tell you that 'Acme Corp' just viewed your pricing page. If you want to turn more visitors into leads on the spot, Proof is the direct tool. Leadfeeder helps your sales team follow up *after* a company has shown interest.
Leadfeeder offers robust, two-way CRM sync. Proof's integrations are unspecified.
Leadfeeder provides native, two-way integrations with major CRMs like Salesforce and HubSpot. Visit data automatically syncs into your CRM, enriching lead records. Proof's documentation does not detail specific CRM integrations. The focus is more on the website-side experience and analytics. This makes Leadfeeder a stronger choice for teams that want seamless data flow between web visits and their sales pipeline. Proof's value is more on the website itself. For a marketing team focused on conversion rates on their site, Proof's lack of deep CRM sync may be fine. For sales ops, Leadfeeder's integration is critical.
Leadfeeder has a free plan. Proof's lowest plan costs $29/month.
Leadfeeder offers a free plan that identifies up to 100 companies monthly. Paid plans start at $99/month (annual) and scale based on identified company volume. Proof has no free plan. Its Basic plan starts at $29/month for up to 1,000 unique visitors. Higher tiers unlock more features and traffic limits. Leadfeeder's free plan is a major advantage for small teams or those testing lead identification. Proof's entry cost is lower than Leadfeeder's paid plan. Value depends on your need. If identifying anonymous companies is key, Leadfeeder's free tier is unbeatable. If you need conversion tools immediately, Proof's lower entry price for its Pro features might be better.
Both tools require setup. Proof offers more educational resources to guide you.
Leadfeeder requires connecting to Google Analytics and installing tracking code. Some users report installation issues. The interface focuses on lead lists and filters. Proof provides a 6-lesson course on website personalization. This suggests a steeper learning curve but offers more strategic guidance for growth teams. Leadfeeder's complexity is in setting up filters and understanding lead data. Proof's complexity is in designing effective personalization strategies. A sales rep might find Leadfeeder easier after setup. A marketer might appreciate Proof's educational content to build a long-term strategy.
Leadfeeder has mixed reviews on support. Proof's support details are limited.
Leadfeeder customer support receives criticism for being unresponsive and unhelpful, especially regarding integration issues. Some users report unresolved bugs for over a year. Proof's support information is sparse. Live chat is only available on the Pro plan ($79/month) and above. No specific support quality data is available. Based on available data, Leadfeeder has a known support problem. Proof's support quality is unknown, which is a risk. For complex technical issues, Leadfeeder's reported support gaps are a serious concern. Proof's lack of information makes it hard to evaluate, but its feature gating of live chat is a downside.
Leadfeeder scales with identified companies. Proof scales with website visitors.
Leadfeeder's pricing and plans scale based on the volume of unique companies identified monthly. This is ideal for growing B2B sales pipelines. Proof's plans scale based on total monthly unique visitors. This suits businesses with growing website traffic needing higher conversion rates. Leadfeeder scales with your sales team's lead generation goals. Proof scales with your marketing team's website traffic and conversion needs. A fast-growing SaaS company might need both: Leadfeeder for lead gen and Proof for on-site conversion.

We found external reviews for Proof to be limited and mixed, with a notable absence of substantive feedback from major review platforms. ⚠️ On Trustpilot, the profile is largely empty, offering no clear user sentiment.

This isn't a typical 'A vs B' battle. Leadfeeder and Proof solve two completely different problems for two different teams. Leadfeeder's superpower is peeling back the curtain on your anonymous web traffic. It tells your sales team exactly which companies are checking you out, even if their employees are remote. That's intelligence you can act on immediately. Proof's superpower is making the most of the traffic you already have. It lets you personalize what visitors see, show social proof, and A/B test to turn more of them into leads right on the spot. The deciding factor is your biggest pain point. Is it not knowing who's interested? That's Leadfeeder. Is it that your traffic isn't converting well enough? That's Proof. Choose Leadfeeder if you're in sales or lead gen and need to identify companies for outreach. Choose Proof if you're in marketing or growth and need to optimize on-site conversions. Some advanced teams might even use both, but for most, picking one depends on which part of the funnel needs fixing first.
Technically, yes, but they serve different purposes. Use Leadfeeder to identify companies visiting your site. Use Proof to personalize the experience for those visitors. You'd be using them for separate stages of the funnel.
Leadfeeder's free plan makes it the better choice for tight budgets. You can identify up to 100 companies monthly at no cost. Proof's cheapest plan is $29/month.
Yes, Leadfeeder requires connecting to your Google Analytics account as part of its setup. This is how it accesses your website traffic data for company identification.
Proof can be used on e-commerce sites to show social proof like recent purchases. However, its core focus is broader website personalization for marketers and growth teams, not specifically e-commerce tools.
Leadfeeder uses a large, constantly updated IP database. It claims to have the highest company recognition rate, identifying the company even if employees work from home with dynamic IPs.
No, Proof does not offer a free plan. Its lowest tier is the Basic plan at $29/month. However, all plans come with a 14-day free trial.
Both tools have their strengths. Choose based on your specific needs.
