The full picture

RB2B and Warmly are the two names that come up in every visitor-identification conversation, and they’re genuinely different products. RB2B is a focused, self-serve tool: person-level identification of US visitors, delivered to Slack, from $79/month. Warmly is an orchestration platform: identification plus intent data, AI agents, chat, and ad sync — priced accordingly, from roughly $700/month to $30k/year.

The honest answer for many teams is neither: if you want identification and the follow-up motion without an enterprise contract, a third category — identification with built-in outreach — fits better. That’s where BusinessMCP sits.

Why teams switch

Choose RB2B if…

Your traffic is overwhelmingly US, you live in Slack, and you want the individual person’s LinkedIn profile to work manually. It’s the cheapest way to get person-level alerts, and setup takes minutes.

Choose Warmly if…

You’re mid-market or enterprise with budget for a $8k–$30k/year orchestration layer, you already run a sequencer + enrichment stack, and you want AI agents coordinating all of it — including on-site chat and LinkedIn ads.

Choose BusinessMCP if…

You want the whole loop — global company identification, enrichment, scoring, AI outreach, booking, CRM, analytics — in one product, self-serve, from $19/month. You give up native person-level reveal (connect an RB2B key if you need it) and gain everything after the identification.

Side-by-side pricing

HubSpot agreed to acquire Warmly on 30 June 2026. Warmly says existing contracts, pricing and product experiences are unchanged for current customers for now, but a standalone roadmap and price list are no longer safe to assume — re-check before you commit to an annual contract.

Plan	Price	Notes
RB2B	$79–$999/mo	credit-based, person-level, US-only; free tier has no contact data
Warmly	~$700/mo – $30k/yr	annual contracts; agents priced separately
BusinessMCP	$19–$499/mo	month-to-month; AI SDR from $199/mo; free analytics plan

Where BusinessMCP is NOT the right choice

An alternatives page you can trust has to cut both ways. Honestly:

BusinessMCP doesn’t do on-site chat popups or LinkedIn ad-audience sync the way Warmly’s agents do (we sync ad audiences to Meta/LinkedIn/TikTok (Google pending developer-token approval), but not Warmly’s microsite/popup layer).
BusinessMCP identifies companies, not individual people, out of the box — person-level reveal (US-only, like every person-level vendor) requires connecting your own RB2B or Leadpipe key.
We are a younger product than most tools on this page. You get faster iteration and direct founder support, but a smaller integration marketplace than a 10-year-old incumbent.
If you only want a raw contact database to export CSVs from, a data vendor is a better fit — BusinessMCP is built around acting on your own website traffic.
Email is our only fully automated outreach channel. LinkedIn steps are drafted for you and sent with one click, deliberately — we will not automate your LinkedIn account — so if you want hands-off LinkedIn sequencing, we are not that tool.

Frequently asked questions

Which has better identification coverage, RB2B or Warmly?

Different axes. RB2B resolves individual people but only for US traffic (5–20% of it, by their own positioning). Warmly resolves companies globally and persons for US traffic on higher tiers. If your traffic is international, company-level tools see far more of it.

Can I use RB2B and Warmly together?

You can, but you’d pay twice for overlapping identification. The more common stack question is identification + outreach — which is one product in BusinessMCP, or RB2B + a sequencer + manual glue otherwise.

Why does BusinessMCP appear in an RB2B vs Warmly comparison?

Because we compete for the same job: turning anonymous website traffic into pipeline. We publish this comparison with real pricing because we win on exactly the dimension the other two leave open — the complete loop at self-serve pricing. Where they’re a better fit, we say so above.
