RB2B Review
Person-level identification for US B2B website visitors — who they are, which company, and enough context to trigger outreach the same day. Adam Robinson's bootstrapped answer to Clearbit's discontinuation.
RB2B at a glance
The RevenueHoop take on RB2B
RB2B is the first visitor-identification tool that actually works at the person level for US B2B traffic — not just "someone from Acme visited" but "Jane Smith, VP Marketing at Acme, visited your pricing page 12 minutes ago." That specificity is the entire pitch. If your inbound is meaningful and US-heavy, RB2B pays for itself inside 30 days. The catch: the signal only produces pipeline if someone on your team reaches out fast. Visits go cold in a day, not a week.
Best for
- B2B SaaS teams with meaningful US inbound traffic (500+ unique weekly visitors)
- Marketing teams running content strategies where knowing "who read" matters
- Sales teams that want to trigger outreach the same day a target account visits
- RevOps teams building signal-triggered outbound motions
- PLG SaaS teams whose signup traffic includes stealth researchers
When to use it
Use RB2B when inbound is real and you have the operational muscle to act on visits within 24 hours. Pair it with your CRM (HubSpot or Attio), your enrichment layer (Clay), and your outbound tool (Smartlead or HeyReach) so a visit triggers a same-day sequence.
RB2B also earns its place for ABM programs — instead of paying six figures for 6sense to say "an account is warming up," pay a fraction of that for RB2B to name the specific person on that account who just visited.
When NOT to use it
Skip RB2B if your inbound traffic is mostly non-US — RB2B's coverage outside the US is limited and person-level identification drops fast. Skip it if you don't have the operational discipline to act on signals same-day; the ROI collapses if visits sit in a Slack channel for a week.
If your signal need is broader account-level intent, 6sense or Warmly might fit better.
Pros and cons
Pros
- Person-level identification for US B2B traffic — nothing else does this at price
- Native Slack alerts and CRM sync
- Simple pricing model — you're not buying a platform, you're buying a signal
- Fast to set up (script + one hour of ops work)
- Genuinely GDPR-conscious approach for a visitor ID tool
- Founder-led product (Adam Robinson) with fast iteration cadence
Cons
- US coverage is strong; international coverage is limited
- Signal accuracy depends on visitor's LinkedIn activity history
- Not a full ABM platform — this is one signal, not a program
- Team without operational follow-through wastes the signal
- Some visits identify at company level only, not person level

The RevenueHoop opinion
RB2B is the most-recommended intent tool in our client engagements right now, and the reason is simple: it produces named people, not vague accounts, at a price a Series A team can afford. The teams that get real pipeline out of it aren't running a fancy program — they've built one workflow that catches an RB2B alert, enriches the person in Clay, and fires a sequence from Smartlead the same day. That's it. That's the motion.
