3 core reasons SDRs and ops teams switch to Derrick. Click to expand each.
01
Web app, nothing to install, no CSV round-trip
＋
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 step in its web app (also in Google Sheets, Claude and the API). The enrichment happens where your team already works.
02
Free plan to start, then €20/month for 10,000 credits
＋
Entry pricing: RB2B at $129/month, Warmly at $10,000/year. Derrick from €20/month is €108/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.
Replace RB2B: enrich companies with a full company profile in Derrick's web app, nothing to install

Most teams pay 2-5x more on add-ons (extra seats, phone credits, integrations) than on the headline base price. Derrick keeps it to one transparent credit model.
For us teams wanting person-level signal, RB2B visitor identification starts at $129/month. Tier ceilings, credit refresh rules, and per-seat economics are all detailed on the RB2B pricing page below.
While other tools pile on features, complex setups, and pricing tiers that grow faster than your results, Derrick focuses on what actually matters:
getting usable leads, in a web app with nothing to install (also in Google Sheets, Claude and the API).
No heavy workflows, No endless configuration. No learning curve.
Signal-based revenue platform category : Warmly entry tier is $10,000/year. Typical use : revenue teams on signal-based outbound. See the complete Warmly pricing page for tier comparison, credit cap behaviour, and annual-vs-monthly delta.
Derrick is a web app - nothing to install, no formulas to learn, no pipelines to migrate. Sign up and you're enriching in under a minute.

"This app saved me so much time and effort. Great for anyone looking to build a contact list or network at scale quickly. As a start-up it's been invaluable."
Alex Clark
Director | SaaS GTM Leader
"Working pretty nifty compared to Snov.Io. Price wise it does give a fair shake, and IMO better interface since it's google sheets."
David Sire
Mortgage Broker at Zero Point Mortgage
"Derrick is a very simple and user-friendly app to enrich your contacts database. Best thing: you can test it for free. And then the price is so low, it's a no brainer."
Etienne Grange
CEO Form'actions
"I have been using other expensive apps or freemium like phantombuster, but Derrick has replaced them all. I love the simplicity of the Google sheet add-in, but what is best is the efficiency it delivers."
Julien Walon Cohen
CEO & Co-founder @ Diffly | B2B Sales Advisor
"Super easy to enrich linkedin urls using this tool. Both personal and company url data can be easily enriched with a click of a button."
Zaid Bilal
RevOps Professional
"Amazing Tool, I would like to advocate this to my colleagues. So that you can get more users. Keep it Up. 5 Stars!"
Asif Hanzala
Lead Generation Specialist at IdeaPeel
"The LinkedIn scraping and email finder combo is incredibly powerful. I can build a complete prospect list with contact info in under an hour. Absolute must-have for outbound."
Michael Kim
SDR Team Lead at CloudScale
"This app is fantastic. Brilliantly created to help small and mid sized businesses."
Dan Hughes
Founder/CEO, AlmanacIO
"Have tested over 10+ LI scraper apps, Derrick beats them all. Simple to use, accurate data, and affordable price."
RB2B is positioned as visitor identification for us teams wanting person-level signal. Warmly is positioned as signal-based revenue platform for revenue teams on signal-based outbound. These are different category bets - RB2B for visitor identification, Warmly for signal-based revenue. Most teams either pick one based on primary use case or stack both for adjacent workflows. Both are established products with real user bases, so the deciding factor is workflow fit, not product quality.
How do RB2B and Warmly pricing actually compare in 2026?
+
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, free to start and 20 EUR a month for 10,000 credits, is the simplest TCO answer: a web app, nothing to install, also in Google Sheets, Claude and the API.
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. That is the capability to test against your own list before it decides anything.
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. That is the difference to test against your own workflow before it decides anything.
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 web-app-first enrichment + search layer (also in Google Sheets, Claude and the API) from €20/month - 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 sits closest to them on the same use case, 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.
