| Decision |  Data SDK | RB2B |
|---|---|---|
| Main focus | Worldwide company identification and page context. | US person-level identification plus company-level identification for global traffic. |
| Identification | Company-level; no individual identity or proven intent. | Its help center distinguishes US person-level results from worldwide company-level results. |
| Working style | Use available company details in your research process; confirm delivery. | Review company and person results separately in a dashboard or supported integration. |
| API and resale | Full API coming soon. Confirm access and white-label/resale rights. | Ask for current API, embedding, and redistribution terms. |
What the vendor documents
- RB2B's company-identification documentation describes global company matching and restricts person-level identification to US visitors. RB2B company-level identification
- RB2B describes a Demandbase partnership for company identification alongside its person-level offering. RB2B and Demandbase
When to consider RB2B
Evaluate RB2B if US person-level identification is part of your requirements, while checking company results separately for other markets.
When to evaluate Data SDK
Evaluate Data SDK if the output you need is a business to research worldwide, rather than a claimed individual visitor identity.
Data SDK offers worldwide company-level visitor identification with available company details and pages viewed. It does not identify the person or prove buying intent. The full API is coming soon; white-label scope and resale terms require agreement. Start free trial opens an email request. Pricing and usage limits are not published.
Ask before choosing.
How are person and company results counted, which markets are supported, and what actions are appropriate for each record type?
- Test useful matches in your own markets, including startups and larger businesses.
- Compare like-for-like company records; distinguish contacts from the person who visited.
- Confirm required integrations, data handling, contract length, pricing units, and any API or resale rights.
A useful pilot.
Compare company-to-company results using the same traffic window. Do not add person counts to company counts and call them unique businesses.
What this comparison does not establish.
RB2B's public documents have differed on plan eligibility over time. Confirm current packaging and credit rules; no match-rate benchmark is asserted here.
