Best-of guide
Buyer intent and signal tools, reviewed
Tools that tell you who is already looking at you, so outreach starts warm instead of cold.
Most of your best leads visit the website, read the pricing page and leave without filling in a form. Signal tools try to put a name or a company on that visit, and on the other places buying interest shows up: community posts, job changes, product usage.
They vary a lot in what they can identify and how, and the privacy rules differ by country. Each review is clear about both.
The tools, highest rated first
- RB2B A website script that names some of your US visitors and posts them to Slack RB2B puts a name, a LinkedIn profile and (on Pro) a business email on a share of your US website visitors, and tells you about them in Slack or your CRM. It costs nothing to try and $149 to $349 a month for most small teams that use it properly. It is worth it if you sell to US companies and get real traffic; it is close to useless if your visitors are mostly outside the US. Best for: You sell B2B to US companies and your site gets at least a few thousand visits a month, so there is something to identify.
- Snitcher A Dutch website visitor tool that tells you which companies are on your site, and names people only once they give you an email Snitcher matches your visitors' IP addresses to companies, shows what those companies read, and alerts you in Slack or your CRM. It names individuals only after they identify themselves through a form, login or tracked email link. It starts at $49 a month and is priced by how many companies it identifies, which makes it good value for B2B teams with European or global traffic who want account-level signals without the legal grey area of naming anonymous people. Best for: A good share of your traffic is in Europe or outside the US, where person-level identification tools either do not work or are hard to defend.
- Common Room A buyer-signal platform that pulls web, CRM, product and community activity into one profile per person, now owned by Zoom Common Room gathers website visits, CRM data, product usage, community activity and third-party intent into one record per person and account, then uses AI agents to research and prioritise them. It starts at $2,500 a month billed annually, so it suits funded B2B teams with real signal volume, not a two-person startup. Zoom bought it in July 2026, which matters if you are signing a multi-year contract. Best for: You sell a developer or product-led tool and your buyers show up in GitHub, Slack, Discord or your own product long before they talk to sales.
