RB2B
Identify individual US website visitors and push them to Slack.
NOT REALLY
why this verdict
Keep it — OpenAI has not replaced it
OpenAI's version overlaps, but does not finish the sales job, so this one is still worth keeping open.
- A named launch, not a vibe named, unlinked
- Visitor identification is data, not generation. OpenAI, February 1, 2025 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? paid only
- 2 replacements listed, all paid.
- What the call is worth nothing to cancel
- No paid entry tier tracked, so there is no subscription to cancel.

The backstory
RB2B became an X phenomenon by giving away person-level identification on a free tier and letting the outrage market it. It sits entirely outside what models do: the value is an identity graph plus a Slack webhook, and no amount of inference reconstructs who just visited your site.
