If one of these is what you need, it may be the better pick. - Community, GitHub, Slack, Discord, and social signals in one place - Unified person and account profiles across many sources - Bombora intent topics and a prospecting database - Dialer and sequences through the Zoom bundle ## Where WhoLayer is different ### Company-level ID is free Company identification is free and unlimited on every plan. Person-level ID is US-only and charged once per person per month; repeat visits are free. ### Alerts where you work Send identified visitors to Slack, signed webhooks, or a daily or weekly email digest. From the Starter plan, filter by title, company size, and the pages they viewed, and sync contacts one way to HubSpot. ### Built for agents A data MCP server with 13 tools and a REST API with an OpenAPI spec. Per-key daily caps, a 250-credit default ceiling per call, read-only keys, and idempotent retries keep an agent's spending predictable. ### One wallet, published per-result prices Visitor ID, Shopper ID, the Data API, and the MCP server draw from the same credits, and every credit cost is listed on the pricing page. Misses aren't charged. ### Opt-outs honored everywhere Opted-out and suppressed people are never returned, delivered, or charged. Global Privacy Control signals are honored, and the rules we enforce are published as a machine-readable policy. ### Monthly plans, spend caps Monthly plans stop at the end of the billing period, and you can set a hard monthly spend cap so overage never surprises you. ### WhoLayer isn't the right fit if - You need signals from social media engagement. WhoLayer doesn't scrape LinkedIn or other social networks. - You need person-level identification of visitors outside the US. WhoLayer identifies people for US traffic only; elsewhere it's company-level, after consent. - You want a full ABM advertising suite, an on-site AI chat agent, or a built-in sequencer and dialer. WhoLayer identifies and enriches; it doesn't run ads, chat, or send email for you. ## Pricing Common Room's published entry price, next to WhoLayer's plans.
