RB2B Alternatives: Honest 2026 Comparison

RB2B identifies your anonymous US website visitors by name, matches them to a LinkedIn profile and business email, and pushes them into Slack within minutes. It's the quickest, cheapest way to put names on traffic. The catch: identification is only half the job — you still have to do something with the name.

If you're researching RB2B, you've probably got the same problem most B2B teams have. People visit your site, read three pages, and leave anonymous. RB2B fixes the anonymous part.

I'm Dag, co-founder of ContactLevel. We don't do exactly what RB2B does — and that's the point of this page. RB2B identifies visitors. We turn identified contacts into ad audiences. I'll be honest about where RB2B is genuinely good, where it stops short, and which alternative fits which job.

This page is opinionated. I run a tool in this space. Read it knowing that.

What RB2B does

RB2B installs a pixel in your site header. Five-minute setup. From there it identifies anonymous visitors and pushes them — name, LinkedIn URL, company, sometimes a validated business email — into Slack or Teams within minutes.

The headline on their site says it plainly: "Identify Your Website Visitors and Boost Your Leads."

Two levels of identification:

→ Person-level — an actual named individual with a LinkedIn profile. This is the part people get excited about. It's US-only.

→ Company-level — which company visited, even when they can't name the person. This runs globally through a Demandbase partnership.

The free plan covers company-level ID. Person-level — the real product — lives on the paid tiers.

That's the whole pitch. Anonymous visitor in, named contact in Slack out. Fast.

What RB2B is good at

Three things, honestly.

It's cheap and fast to start. A forever-free company-level plan, paid plans from around $79/month, and a five-minute pixel install. No sales call, no annual contract to test it. For a team that just wants to see who's on their site, RB2B is the lowest-friction option in the category.

Person-level US identification actually works. Most visitor-ID tools — Leadfeeder, the old-school IP-based ones — only ever give you a company. RB2B puts a real name and LinkedIn profile on a chunk of your US traffic. For a US-focused sales team, that's the difference between "someone at Acme looked at pricing" and "Sarah Chen looked at pricing."

The Slack workflow is genuinely simple. Visitor lands in a Slack channel, a rep sees it, a rep reaches out. No dashboard nobody opens. It meets sales teams where they already work.

That's the real list. RB2B does one job and does it without much fuss.

Where RB2B falls short

This is the part that matters if you're deciding.

Identification without activation

You get a name in Slack. Then what?

That's the honest gap. RB2B tells you who visited. It does not help you reach them again. There's no ad audience, no retargeting, no way to keep warming that person across the channels where they actually spend time.

So the value depends entirely on a rep seeing the alert, caring, and acting fast. Most identified visitors aren't ready for a sales call yet — they read one page. Pinging them cold the moment they're spotted often burns the relationship before it starts.

A name with no next step is just a notification. The work is still in front of you.

Person-level is US-only

RB2B's named-person identification only works for US traffic. Outside the US it drops to company-level through Demandbase — you learn the company, not the individual.

If a meaningful share of your pipeline is in Europe, the UK, or anywhere else, the headline feature simply doesn't fire for those visitors.

Coverage is partial, and Slack-first is a ceiling

RB2B resolves a portion of your traffic, not all of it. Coverage varies by tier and by how identifiable your visitors are — plenty of buyers browse from home networks or with privacy settings that block resolution entirely.

And everything routes through Slack-style alerts and outreach tools. That's great for a rep-led motion. It's a hard ceiling if you want to run marketing to these people — sequence content, retarget across platforms, warm a whole buying committee. RB2B wasn't built for that, and it doesn't pretend to be.

---

The real question: identify, then what?

Here's the framing that decides which tool you need.

Website visitor identification is step one. The harder, more valuable step is what happens next. A visitor who read your pricing page is interested — but probably not ready to talk to sales. Most of them aren't.

If your answer to "then what?" is "a rep DMs them," RB2B fits.

If your answer is "we keep showing them the right content until they're ready" — across LinkedIn, Meta, Google, wherever they are — you need an activation layer. That's a different category, and it's where I'll be transparent about what we built.

Where ContactLevel is different

ContactLevel isn't a Slack-alert tool. It's the activation layer that sits after identification.

It turns identified visitors into ad audiences

Take the contacts RB2B identifies — or any contact list — and ContactLevel enriches each one with personal identifiers, then syncs them as custom audiences to LinkedIn, Meta, Google, Reddit, and X.

That enrichment matters. A raw CSV upload matches 20-50% of your list on most ad platforms because your CRM has business emails and people sign up to Meta and Google with personal ones. Identity enrichment maps business identities to personal identifiers and pushes match rates to 70-99%. That's 50-70 data points per contact versus the 1-3 in a typical export.

So a visitor RB2B spots in Slack becomes a person you can actually keep reaching with ads — not just a name a rep may or may not follow up on.

It does the warming RB2B can't

Instead of pinging a cold visitor the second they're identified, you add them to an audience and run content that matches where they are in the buyer journey. Problem-aware visitors get educational content. Solution-aware visitors get comparisons. Product-aware visitors get case studies.

Companies running this contact-level approach see 2.2x more meetings booked and 470% higher email reply rates when prospects are warmed with ads before outreach — because by the time a rep reaches out, the person already knows who you are.

It's transparent and self-serve

Grow is $1,000/month for 10,000 contacts. Scale is $2,500/month for 30,000. 14-day free trial, 1,000 contacts included, no sales call to start.

That's a different price point than RB2B's $79-$200/month — because it's a different job. RB2B is the cheapest way to get names. ContactLevel is the way to act on them at scale across every platform.

RB2B alternatives, honestly

If RB2B isn't the fit, here's the rest of the field — and what each is actually best for.

→ ContactLevel — best when your real gap is activation, not identification. Enriches contacts and syncs them to five ad platforms at 70-99% match rates so identified visitors become retargetable audiences. Pairs with RB2B rather than replacing it: RB2B identifies, ContactLevel activates. Read the full website visitor identification guide for how the two halves fit together.

→ Vector — the closest like-for-like. Vector started with website visitor identification and added contact-level ads on top, so it covers both identify and activate in one tool. LinkedIn-strong, newer, sales-led pricing with no public number. Worth a look if you want one vendor for both jobs and don't mind a sales call. See the Vector comparison.

→ Leadfeeder (Dealfront) — company-level only, IP-based, strongest in Europe. It won't name the individual, but for EU-heavy, office-based traffic and an ABM motion, it delivers solid company signal from around €99/month. Best for teams that need company-level ID with real EU coverage, not person-level US data.

→ Warmly — person and company-level ID plus AI-driven engagement (chat, alerts, orchestration) bundled together. It covers more of the workflow than RB2B, but it's priced for larger teams — its AI agents start around $15,000/year. Best when you want identification and automated engagement in one enterprise platform.

The honest summary: RB2B is the cheap, simple way to put US names on traffic and alert sales. If you want to do marketing to those people — retarget them, warm a buying committee, run content across platforms — that's an activation problem, and RB2B doesn't solve it. That's what ContactLevel is for.

Frequently asked questions

How much does RB2B cost?

RB2B has a forever-free plan with company-level identification (around 150 resolutions/month after a 7-day trial). Paid plans start at about $79/month for the Starter tier. Person-level identification — names, LinkedIn profiles, business emails — sits on the higher tiers, roughly $150-$200+/month depending on resolution volume. All plans are credit-based and US-only for person-level data.

What is the best RB2B alternative?

It depends on the job. If your real gap is activation — turning identified visitors into ad audiences — ContactLevel enriches and syncs visitors to LinkedIn, Meta, Google, Reddit, and X. If you want company-level ID with strong EU coverage, look at Leadfeeder/Dealfront. If you want visitor ID plus AI-driven engagement at enterprise scale, look at Warmly. Vector is the closest like-for-like if you want visitor ID and contact-level ads in one tool.

RB2B vs ContactLevel — what's the difference?

RB2B identifies anonymous US website visitors and pushes them to Slack for sales to act on. ContactLevel takes contacts — including the visitors RB2B identifies — enriches them with personal identifiers, and syncs them as custom audiences to five ad platforms at 70-99% match rates. RB2B answers "who visited?". ContactLevel answers "now reach them everywhere with the right content." They solve different halves of the same problem.

Is RB2B person-level identification US-only?

Yes. RB2B's person-level identification — putting an actual name and LinkedIn profile on an anonymous visitor — works only for US-based traffic. Outside the US, RB2B falls back to company-level identification through its Demandbase partnership, which tells you the company but not the individual.

Can I use RB2B and ContactLevel together?

Yes, and that's a common setup. RB2B identifies the visitor and alerts your sales team in Slack. ContactLevel enriches that same contact and adds them to ad audiences so you can keep warming them across LinkedIn, Meta, and Google while sales follows up. Identification feeds activation.

Does RB2B do retargeting or run ads?

No. RB2B identifies visitors and delivers them to Slack, your CRM, or outreach tools. It doesn't build ad audiences or run paid campaigns. To retarget identified visitors at the person level, you need an activation layer like ContactLevel that enriches the contact and syncs it to ad platforms.

Try ContactLevel

If RB2B is already naming your visitors, the next question is what you do with them. The fastest way to find out is to run both.

→ Keep RB2B for the Slack alerts your reps act on. → Add ContactLevel to enrich those same contacts and retarget them across five platforms — 14-day free trial, 1,000 free contacts, self-serve at audiences.contactlevel.com.

Identification gets you the name. Activation gets you the meeting.
