Why teams pick Derrick over RB2B and Warmly
3 core reasons SDRs and ops teams switch to Derrick. Click to expand each.
01 Built for teams whose pipeline runs in Sheets
The friction with RB2B and Warmly isn't the data quality — it's the workflow shape. Export from the platform, import into Sheets, hope the columns line up. Derrick collapses all of that into a single formula call. The enrichment happens where the data already lives, with the team that already owns the sheet.
02 One price for unlimited rows : $10/month total
The total-cost-of-ownership math : at RB2B's $129/month or Warmly's $10,000/year entry tier, a 3-seat team runs $150-600/month in year 1. Derrick at $10/mo flat is $120/year total. The break-even on switching pays back in week 2 for most teams.
03 Plug Derrick into Claude / ChatGPT via MCP — no glue code
For teams adopting AI SDR / RevOps workflows : Derrick's MCP support means your enrichment layer is callable by any compliant agent (Claude, ChatGPT, Cursor, n8n with MCP nodes). RB2B and Warmly require Zapier or custom code at this layer — a meaningful integration tax as AI-agent stacks mature.

G2 reviewers rate RB2B at 4.5/5 and Warmly at 4.6/5 — both products work, the deciding factor is workflow fit, not product quality.

+
RB2B entry-paid tier : Plus at $129/month. Next tier up is Pro ($249/month). RB2B's free tier : Free forever (limited identifications). Warmly entry-paid tier : AI Web-Deanonymization (Starter) at $10,000/year (or $3,250/quarter). Next tier up is Data + Signals ($15,000-$20,000/year). Warmly's free tier : Free tier (limited deanon). Worth noting : Derrick App at $10/month for unlimited rows is the simplest TCO answer if your workflow already lives in Sheets.
What's the biggest reason to pick RB2B over Warmly?
+
Person-level signal is materially different from account-level. A Slack alert that says "Jane Smith, VP Sales at Acme just visited /pricing" creates a specific outbound action. An alert that says "someone at Acme visited" creates a guess. The signal granularity changes what's possible in outbound workflows. (Source : Mei C., Head of Sales, G2 review (Feb 2026).) If this single capability maps to a real pain in your sales motion, RB2B is the right pick over Warmly.
What's the biggest reason to pick Warmly over RB2B?
+
Speed-to-respond is genuinely different from ABM dashboards. Most account-ID tools surface signal in a dashboard you check daily or weekly. Warmly fires the signal into Slack, sequences, and chat instantly. Reviewers consistently cite this as the deciding factor versus 6sense + Leadfeeder. (Source : Mei C., RevOps Lead, G2 review (Feb 2026).) If this is the differentiator that matters most for your stack, Warmly is the right pick over RB2B.
Can Derrick replace both RB2B and Warmly?
+
RB2B (visitor identification) and Warmly (signal-based revenue platform) cover different category needs, so the question depends on which one Derrick maps against. Derrick is a Sheets-native enrichment + search layer at $10/mo flat — it directly substitutes for the data layer of either tool. For the platform-specific features (sequencing, intent, automation), Derrick complements RB2B and Warmly rather than replacing them outright.
Beyond RB2B and Warmly, what other tools should I evaluate?
+
Four other tools in the same competitive set worth evaluating : Leadfeeder, Albacross, Visitor Queue, Dealfront. Each has its own positioning trade-off versus RB2B and Warmly — Leadfeeder typically appears as a direct competitor on G2 review pages, with Albacross, Visitor Queue, Dealfront as adjacent picks for different team sizes or use cases. Read the dedicated reviews to weigh feature surface, pricing model, and geographic depth against your real sales motion.
