Both Leadpipe and RB2B promise to tell you who’s visiting your website. Install a script, see names and contact info appear, reach out before your competitors do. The pitch sounds identical.
The delivery is not.
I’m George, founder of Leadpipe. I’ve spent years building our identity graph and testing every major visitor identification tool on the market. RB2B is one of them. This isn’t a hit piece — RB2B does some things well, and I’ll give credit where it’s due. But when we ran both tools side by side on the same website traffic, the results weren’t close.
Leadpipe delivered 240-300% more identified contacts than RB2B from the exact same visitors. This post explains why, and helps you decide which tool is right for your team.
Quick Verdict
Before we go deep, here’s the high-level comparison across the dimensions that matter most:
| Dimension | Leadpipe | RB2B |
|---|---|---|
| Match Rate | 30-40% (deterministic) | 5-15% (probabilistic) |
| Matching Method | Proprietary identity graph | LinkedIn profile matching |
| Email on Starter Plan | Yes (personal + professional) | No (Slack delivery only) |
| Phone Numbers | Yes, all plans | No |
| Behavioral Data | Page views, clicks, scroll depth, return visits | Basic page views |
| Starting Price | $147/mo (500 IDs) | Free (150 IDs, no email) |
| Price for Email Access | $147/mo | $349/mo (Pro required) |
| Integrations | 200+ (HubSpot, Salesforce, Zapier, webhooks) | Slack + limited options |
| White-Label | Yes ($1,279/mo) | No |
| Identity Graph | Proprietary, first-party | Third-party LinkedIn data |
The short version: RB2B is fine if you want a free taste of visitor identification delivered to Slack. Leadpipe is what you use when you’re serious about converting traffic into pipeline.
How We Tested
No hand-waving here. We ran a controlled comparison:
- Same website with consistent traffic sources (organic, paid, direct)
- Same time period — both tools active simultaneously for 30 days
- Same pixel placement — both scripts installed on every page
- 10,000+ unique visitors during the test window
We measured three things:
- Total identified contacts — how many visitors each tool could put a name to
- Data completeness — what contact information was actually returned
- Data accuracy — spot-checked a random sample of 200 identifications against known visitor data
The results were consistent across multiple test periods. This wasn’t a one-time fluke.
Match Rate Comparison
This is where the gap is impossible to ignore.
On 10,000 monthly unique visitors during our test:
| Metric | RB2B | Leadpipe |
|---|---|---|
| Visitors identified | 500-1,500 | 3,000-4,000 |
| Match rate | 5-15% | 30-40% |
| Leads you’re missing | 85-95% of identifiable traffic | 60-70% of identifiable traffic |
That’s not a marginal improvement. That’s 240-300% more identified contacts from the exact same traffic.
Let’s put that in revenue terms. If 5% of identified visitors convert to a sales conversation, and your average deal is worth $5,000:
- RB2B: 1,000 IDs x 5% conversion = 50 conversations = $250,000 potential pipeline
- Leadpipe: 3,500 IDs x 5% conversion = 175 conversations = $875,000 potential pipeline
Same website. Same visitors. $625,000 difference in potential pipeline per month.
The match rate gap isn’t a feature comparison footnote. It’s the entire ballgame.
The LinkedIn Problem
Why is the match rate gap so large? It comes down to how each tool identifies visitors.
RB2B relies on LinkedIn profile data. Their matching process connects browser signals to LinkedIn profiles. If your visitor has a LinkedIn profile that can be linked to their browsing session, RB2B identifies them. If they don’t? RB2B returns nothing.
This creates several blind spots:
- Visitors without LinkedIn profiles — more common than you’d think, especially outside the tech/sales bubble
- LinkedIn profiles that can’t be linked — privacy settings, VPN usage, or insufficient data points break the chain
- Non-professional visitors — potential customers who browse from personal devices without LinkedIn cookies active
- International visitors — LinkedIn penetration varies dramatically by country
Leadpipe matches through multiple data points. Our proprietary identity graph doesn’t depend on any single social network. We match through business email addresses, phone numbers, firmographic signals, and cross-referenced data points. If one signal is missing, others can still complete the identification.
This is also the difference between probabilistic and deterministic matching:
- RB2B (probabilistic): “Based on available signals, this visitor is probably John Smith from Acme Corp.” Confidence varies. Sometimes it’s wrong.
- Leadpipe (deterministic): “This visitor is John Smith from Acme Corp, verified through multiple confirmed data linkages.” High confidence. Verified match.
When your sales team is reaching out to identified visitors, accuracy matters as much as volume. Emailing the wrong person doesn’t just waste time — it damages your sender reputation and your brand.
Data Quality Comparison
Match rate tells you how many visitors get identified. Data quality tells you what you can actually do with those identifications.
Here’s what each tool returns:
RB2B Free Plan ($0/mo, 150 IDs)
- Name
- LinkedIn profile URL
- Company name (from LinkedIn)
- Job title (from LinkedIn)
- Delivery: Slack only
What’s missing: No email address. No phone number. No way to directly contact the person outside of sending a LinkedIn connection request.
RB2B Pro ($349/mo)
- Everything in Free
- Email address
- Additional company data
What’s still missing: No phone numbers. No personal email addresses. No behavioral tracking beyond basic page views.
Leadpipe — All Plans (starting at $147/mo, 500 IDs)
- Full name
- Personal email address
- Professional/work email address
- Phone number
- LinkedIn profile URL
- Company name
- Job title
- Industry
- Company size
- Page views with timestamps
- Click behavior and scroll depth
- Return visit tracking
- Marketing attribution data
- Session duration and engagement scoring
Every Leadpipe plan includes the full contact record. We don’t gate email behind a premium tier or charge extra for phone numbers. If we identify someone, you get everything we know about them.
The difference in data completeness has a direct impact on outreach strategy:
| Outreach Channel | RB2B Free | RB2B Pro | Leadpipe |
|---|---|---|---|
| LinkedIn outreach | Yes | Yes | Yes |
| Cold email | No | Yes | Yes |
| Phone call | No | No | Yes |
| Multi-channel sequence | No | Partial | Yes |
| Personalized by behavior | No | No | Yes |
With Leadpipe, your sales team can say: “I noticed you spent 8 minutes on our pricing page yesterday and came back today to read our integration docs. Can I help you evaluate whether we’re the right fit?” That’s a fundamentally different conversation than a blind LinkedIn connection request.
Pricing Breakdown
Raw pricing doesn’t tell the full story. What matters is cost per actionable lead — how much you’re paying for each visitor you can actually reach out to.
Plan Comparison
| Plan | Monthly Cost | IDs Included | Email Access | Phone Access |
|---|---|---|---|---|
| RB2B Free | $0 | 150 | No | No |
| RB2B Pro | $349 | Varies | Yes | No |
| Leadpipe Starter | $147 | 500 | Yes | Yes |
| Leadpipe Growth | $297 | 1,500 | Yes | Yes |
| Leadpipe Scale | $497 | 5,000 | Yes | Yes |
Cost Per Identified Contact
Now layer in match rates on a site with 10,000 monthly visitors:
| Metric | RB2B Pro | Leadpipe Starter |
|---|---|---|
| Monthly cost | $349 | $147 |
| Match rate | 5-15% | 30-40% |
| Contacts identified | 500-1,500 | 3,000-4,000 |
| Cost per contact | $0.23-0.70 | $0.04-0.05 |
| Contacts with email | 500-1,500 | 3,000-4,000 |
| Contacts with phone | 0 | 3,000-4,000 |
Even if you compare Leadpipe’s $147/mo against RB2B’s free tier — which only gives you 150 identifications per month without email addresses — the math favors Leadpipe for any team that plans to actually contact their visitors.
RB2B’s free plan is genuinely useful for one thing: testing whether visitor identification works for your business before committing budget. But if you’re past that stage and ready to generate pipeline, 150 LinkedIn-only identifications per month won’t move the needle.
Integration and Delivery
RB2B
RB2B’s core delivery channel is Slack. Their Slack integration is polished and notifications arrive quickly. For teams that live in Slack and just want a heads-up when someone visits, this is smooth.
Beyond Slack, RB2B offers integrations with some CRMs and outreach tools, but the ecosystem is more limited.
Leadpipe
Leadpipe delivers through Slack too — but that’s just one of 200+ native integrations, including:
- CRMs: HubSpot, Salesforce, Pipedrive, Close
- Outreach: Instantly, Smartlead, Apollo, Outreach
- Automation: Zapier, Make, n8n, webhooks
- Enrichment: Clay, Clearbit
- Custom: Full API access for building your own workflows
The webhook and API access is especially important for teams that run custom workflows or need visitor identification data feeding into their existing tech stack automatically.
Features RB2B Doesn’t Have
Beyond match rates and data quality, Leadpipe includes capabilities that RB2B simply doesn’t offer:
Suppression Lists
Upload your existing customer list or do-not-contact list. Leadpipe won’t waste identifications on people you already know. RB2B counts every identification against your quota regardless.
Page Exclusions
Only identify visitors on high-intent pages (pricing, demo request, case studies) and ignore blog readers or careers page visitors. Focus your identification budget where it matters.
White-Label for Agencies
At $1,279/mo for 20,000 identifications, agencies can resell Leadpipe under their own brand. Build visitor identification into your agency offering without revealing the technology provider. RB2B doesn’t offer white-label.
API Access for Platforms
Build visitor identification directly into your SaaS product with Leadpipe’s API. OEM licensing available for platforms that want to offer identification as a native feature.
Behavioral Tracking
Leadpipe tracks more than page views:
- Click behavior and engagement patterns
- Scroll depth on key pages
- Time on page and session duration
- Return visit frequency and recency
- Marketing attribution (which campaign, source, or keyword brought them)
This behavioral data transforms cold outreach into warm, contextual conversations.
Return Visitor Identification
When a previously identified visitor comes back days or weeks later, Leadpipe recognizes them and alerts your team. You’ll know when a prospect who visited your pricing page last month is back looking at case studies today. That timing signal is gold for sales teams.
Where RB2B Wins
I said this wouldn’t be a hit piece, and I meant it. Here’s where RB2B has genuine advantages:
Free Tier for Testing
RB2B’s free plan (150 IDs/month) is the easiest way to test whether visitor identification works for your business. No credit card, no commitment. If you’re not sure this category of tool is right for you, start with RB2B Free and see what happens.
Slack-First Experience
If your entire workflow lives in Slack and you just want a notification when someone interesting visits your site, RB2B’s Slack experience is clean and well-designed. The notifications are clear and actionable.
Simpler Interface
RB2B is a more focused tool with fewer features. For small teams that just want LinkedIn profiles of their visitors without a learning curve, that simplicity is a feature, not a bug.
Brand Recognition
RB2B has strong awareness in the B2B SaaS community, particularly among sales-led teams on LinkedIn. Their content marketing and founder-led growth strategy has built trust with a specific audience.
Who Should Choose Which
Choose RB2B if:
- You’re testing visitor identification for the first time and want a free starting point
- LinkedIn profiles are sufficient for your outreach strategy
- Your team lives in Slack and doesn’t need CRM integration
- You have low traffic (under 1,000 monthly visitors) and 150 IDs is enough
- Budget is $0 and that’s non-negotiable
Choose Leadpipe if:
- You need email addresses and phone numbers, not just LinkedIn profiles
- Match rate matters — you want to identify 3-4x more visitors from the same traffic
- You run multi-channel outreach (email + phone + LinkedIn)
- You need CRM integration (HubSpot, Salesforce, Pipedrive)
- You’re an agency that needs white-label capabilities
- You want behavioral data to personalize outreach
- You care about cost per lead, not just sticker price
- You’re serious about turning website traffic into sales pipeline
The Bottom Line
RB2B popularized the idea of person-level website visitor identification, and they deserve credit for that. Their free tier remains a useful entry point for teams that want to experiment with the concept.
But if you’ve moved past the experimentation phase and you’re ready to build a real pipeline from your website traffic, the match rate difference alone makes this decision straightforward.
240-300% more identified contacts. Full contact data on every plan. Deterministic matching you can trust. At a lower price per identified lead.
Same visitors. Dramatically different results.
