What Artemis GTM's visitor-identification ranking establishes. The ranking provides four names and a category-level function, but not enough methodology or comparative evidence to identify a universal winner. What does "best" mean in a visitor-identification ranking? The supplied material names several leading products, but it does not include the evidence needed to answer that question. Artemis GTM's "Best B2B Visitor Identification Software 2026", published October 24, 2026, ranks Warmly, RB2B, Clearbit, and 6sense as leading B2B website visitor-identification tools. The supplied summary says the tools de-anonymize traffic by matching visitors. Those details establish a shortlist and a shared category. They do not establish why the four products lead the category or whether one is the strongest choice for a particular use case. Three claims the preview supports. The available information supports three limited conclusions: 1. The article concerns B2B website visitor-identification software. 2. Warmly, RB2B, Clearbit, and 6sense are among the options Artemis GTM ranks as leading tools. 3. Visitor matching is part of the function described in the summary. The wording matters. Being named among the leading options is not the same as winning a documented head-to-head test. Likewise, placing several products in one category does not demonstrate that they provide identical outputs or operate in identical ways. What remains outside the record. The supplied material does not state the ranking criteria, testing method, data set, pricing basis, or performance results. It also does not explain what information the matching process returns, what sources support a match, or how Artemis GTM assessed each vendor. Without those details, the ranking cannot be independently reproduced from the preview. Claims about match rates, accuracy, geographic coverage, integrations, regulatory suitability, or business outcomes would require the complete article or additional vendor documentation. Use the names as a research boundary. The defensible value of the summary is that it narrows a broad market to four named candidates. A reader can use those names to organize further research, but the supplied evidence does not support selecting one solely because it appears in the ranking. The next step is to read the complete source and identify the standards behind "best." If those standards are not stated, any comparison should rely on current, directly sourced information from the vendors and on requirements defined by the prospective buyer. For now, Artemis GTM's list establishes that Warmly, RB2B, Clearbit, and 6sense are presented as leading visitor-identification tools. It does not, from the supplied summary alone, establish a universal winner.

Choose Clearbit (Breeze Intelligence) if you are deep in the HubSpot ecosystem and want native enrichment for marketing and forms inside HubSpot, with minimal setup. Choose Clay if you want provider-agnostic waterfall enrichment, AI research, and the flexibility to build custom data workflows, and you have appetite for a learning curve. Choose a focused enrichment layer like Enrich if you want high waterfall match rates without HubSpot lock-in or workflow building. Enrich queries multiple providers per contact and returns one verified record through a simple API, MCP server, or upload, on transparent per-credit pricing. Breeze Intelligence for HubSpot-native enrichment with low setup. Clay for provider-agnostic waterfall workflows. Enrich for high match rates without HubSpot lock-in or workflow building. What Clay is best at. Clay is a flexible engine for go-to-market data work, built around waterfall enrichment. For each record, it can query a chain of providers and keep the first verified result, which lifts coverage above any single source. Layered on top are AI research, spreadsheet-style workflows, and integrations that let you run enrichment and outreach end to end. You pay credits for the data you actually use. For teams that want maximum coverage and the freedom to combine sources, Clay is the more powerful option. It is not tied to one vendor's database, which matters as single-source match rates fluctuate. The trade-off is complexity. Clay has a real learning curve, workflows take time to build and maintain, and credit costs can climb with heavy usage. It rewards teams that invest in it. What Clearbit (Breeze Intelligence) is best at. Clearbit's strength was always clean B2B enrichment, and under HubSpot it is now Breeze Intelligence, a native enrichment layer inside the HubSpot platform. For HubSpot-centric marketing teams, that integration is the headline: enrichment on forms, contact records, and workflows without leaving HubSpot, with minimal setup. If your entire go-to-market motion runs in HubSpot, Breeze Intelligence is the path of least resistance. It is built for that ecosystem and removes the integration work other tools require. The trade-offs since the acquisition are real. Practitioners report rising effective pricing as enrichment moves into HubSpot's packaging, and some report declining match rates compared with the standalone Clearbit of years past. And because it is HubSpot-native, it is less useful if you are not committed to HubSpot or need provider-agnostic data. Head-to-head by what matters. Data model and match rates: Clay wins on coverage by combining providers in a waterfall, which holds up even when any single source degrades. Clearbit relies more on a primary source, and practitioners have reported match rates slipping post-acquisition. If maximum fill rate matters, Clay's multi-provider model is more resilient. Ecosystem fit: Clearbit wins for HubSpot users. As Breeze Intelligence, it is native to HubSpot and requires almost no setup for HubSpot marketing teams. Clay is provider-agnostic and integrates broadly, but it is not a native part of any CRM. Your ecosystem largely decides this category. Pricing: Clay's usage-based credits give you control and transparency over what you spend. Clearbit's pricing is increasingly bundled into HubSpot and Breeze packaging, which can be convenient for HubSpot customers but harder to evaluate on a per-record basis and reportedly more expensive than before. For predictable per-record cost, Clay is clearer. Flexibility and use cases: Clay wins on flexibility: AI research, custom workflows, and combining sources for creative outbound and data ops. Clearbit is more focused on straightforward enrichment within HubSpot. Power users lean Clay; HubSpot marketers lean Clearbit. Setup and learning curve: Clearbit wins on simplicity for HubSpot users, with low setup. Clay requires real time to learn and build. If you want enrichment running today inside HubSpot, Clearbit is faster; if you want a flexible engine and will invest in it, Clay. Where Enrich fits in. Clay gives you waterfall coverage but asks you to build workflows. Clearbit gives you simplicity but ties you to HubSpot and a single source. Enrich is the focused middle: provider-agnostic waterfall enrichment delivered as a ready-to-use service. Enrich queries multiple providers per contact and returns one CRM-ready record with both email and phone, through a simple API, an MCP server, or a direct upload, with no HubSpot dependency and no workflow building. You get high match rates from combining sources, on transparent per-credit pricing, and you can write back into HubSpot, Salesforce, or any system. For teams that want enrichment results without lock-in or a learning curve, it is the cleaner path. Cost comparison Clay Launch: $167/mo platform fee plus separate provider costs. Clearbit: bundled into HubSpot/Breeze packaging. Enrich Growth Pack: $49/mo all-in for 100K credits, waterfall built in, no HubSpot dependency. Which should you choose? Choose Clearbit (Breeze) if you live in HubSpot and want native, low-setup enrichment for marketing. Choose Clay if you want provider-agnostic waterfall enrichment and flexible workflows and will invest in learning it. Choose a focused enrichment API if you want high match rates without HubSpot lock-in or workflow building. Frequently asked questions. Try Enrich for free. 100 free API credits.
