RB2B vs Vector
Both put names to anonymous US website visitors at the person level, then send them somewhere you can act. RB2B is the free, Slack-native warm-lead feed. Vector is the funded platform that turns identity into intent, CRM signals, and retargeting audiences. Here is how they compare.

Same signal, two different jobs
Both de-anonymize US site traffic down to the person. They split on what you do next with that identity.
Free to start and Slack-native, it pushes an identified visitor's name and LinkedIn profile straight to your team in real time. Built to act on warm traffic fast, with a person-level paid tier from $79 a month.
Person-level de-anon plus multi-source intent, CRM sync, and retargeting audiences across LinkedIn, Google, and Meta. Newer and backed by a $10M round, it closes the loop into paid and CRM, from $399 a month.

What real users say
Public review scores and the themes that come up most, checked June 2026. Counts drift, so the live links are the source of truth.
RB2B
Praised for: a genuinely free start, US person-level coverage, Slack-native immediacy, and fast setup.
Watch-outs: it only identifies a fraction of traffic, US-only, and the January 2026 free-tier downgrade to company-level drew complaints.
Vector
Praised for: intent and ads in one place, contact-level ad audiences, quick setup, and a credible funded team.
Watch-outs: usage-based pricing uncertainty, a newer and thin review base, a high Target floor, and no built-in outreach.
Why only G2 here. Both are newer tools without a meaningful Capterra or Trustpilot base, so G2 is the one place with real reviews for each. Note the sample sizes: RB2B has around 281 reviews, Vector only about 26, so Vector's 4.5 is promising but far less tested. Weigh the themes, and the fit, over the number.
Where each one actually wins
Six things separate these tools in practice. Here is the honest call on each.
What you do with the identity
Edge: dependsThis is the defining split. RB2B is a cheap, real-time feed of warm names into Slack. Vector turns the same identity into retargeting audiences, intent, and CRM signals. They do different jobs, so the "winner" is whichever your motion needs. A lean SDR team and a marketing team running paid will land in different places.
Match rate and coverage
Edge: splitRB2B claims 40 to 45% of US traffic at the person level, Vector 15 to 30% at the contact level, but neither is independently audited and real-world rates run lower. Both are US-only and exclude EU visitors at the person level. The number that matters is the one you see on your own traffic, so test before you commit.
Price and free tier
Edge: RB2BRB2B is free to start (company-level) and runs $79 to $199 for person-level identity. Vector starts at $399, and its Target tier floors around $36,000 a year. If budget is the constraint and you just need warm names, RB2B is the clear cheaper entry. Vector costs more because you are buying a wider platform.
Delivery and workflow
Edge: dependsA Slack-first outbound motion favors RB2B, which is built to drop identified names where your reps already work. CRM-native enrichment plus ad-audience activation favors Vector, which wires identity into paid and pipeline. Both push to Slack and a CRM, so the deciding factor is which downstream workflow you actually run.
Intent depth and enrichment
Edge: VectorVector's multi-source signals, page visits, ad clicks, email, and job changes, plus ad activation, go well beyond RB2B's page-visit-only view. RB2B tells you who showed up; Vector layers context on why they might be in-market. If intent depth drives your prioritization, Vector has the wider picture here.
Maturity and support
Edge: VectorA fresh $10M round, a CSM, and a private Slack on the Target tier give Vector more support muscle to lean on. RB2B is the more established and simpler product, with a larger review base, but lighter hands-on support. If white-glove help matters as you ramp, Vector has the edge, with the caveat that it is the newer company.

What each one costs in 2026
Verified from each official pricing page in June 2026. Read the seat model, not just the headline number.
RB2B
USD / per resolution- Free
150 resolutions, company-level only$0 - Starter
300 resolutions, person-level, LinkedIn URLs to Slack$79/mo - Pro
600+ resolutions, business emails, all integrations$149/mo
7-day trial. Pro+ runs $199/mo for premium resolution. Extra domains are $99/mo each. The free tier became company-level only in January 2026.
Vector
USD / per identified visitor- Reveal
2,500 visitors, de-anon, CRM sync, Ad Reveal$399/mo - Reveal
7,500 visitors$799/mo - Target
ad audiences, annual commitmentfrom $3,000/mo
14-day trial, no free tier. Target adds signal-driven ad audiences, ad-platform sync, and a CSM, and floors around $36,000 a year.
True cost at scale. These price for different jobs. RB2B's free-to-$199 ladder keeps a warm-lead feed cheap. Vector starts at $399 and its audience tier is a five-figure annual commitment, because you are buying an ads and CRM platform, not just a list of names. Price the job you actually need, not the entry tier.
What neither tool does well
Both are identity engines, so they share the same blind spots. Worth knowing before you expect either to carry your whole motion.
Both identify US visitors only. EU traffic is excluded from person-level identity, so neither helps much outside North America.
Both hand you an identity. Neither sends the email, runs the sequence, or books the meeting. You still bring the outbound.
Identity resolution is probabilistic and partial. Treat the output as a strong signal to act on, not a guaranteed match.

Our take, after running both
This comes down to how you operate, not a feature count. Here is how we'd call it in three situations.
The free start and the $79 to $149 person-level tiers give an SDR team warm names in Slack without a platform commitment.
If you already run LinkedIn or Google ads, turning identified visitors into retargeting audiences and CRM signals is exactly Vector's job.
A de-anonymized visitor is a signal. Someone still has to target the right ones, time the outreach, and send it. That part is on you, or on us.
Not sure which fits? We run signal-based outbound for early-stage teams and will tell you straight.
