Leadfeeder sells "buying signals" - but signal type matters. Vendor-coop intent, third-party clickstream and first-party site visits aren't equivalent. The side-by-side comparison below isolates Leadfeeder's actual signal source + freshness against the alternative: Derrick's Sheets-native account research that lets you build a custom signal pipeline.

CURSOR 3 core reasons SDRs and ops teams switch to Derrick. Click to expand each.
If your B2B data ends up in Google Sheets anyway (most teams' do), running it through Leadfeeder or Warmly first means two unnecessary hops : platform → CSV → Sheets. Derrick removes both hops. One add-on, one formula, results in the next column. The unit-of-work shrinks from "run the export" to "drag the formula down".
Leadfeeder (Free Lite forever · Visitor ID from €99/mo) and Warmly ($10,000/year) follow the SaaS-standard model : tier the features, cap the credits, upsell when you outgrow it. Derrick is the opposite — one tier, $10/month, no caps, no seats. Predictable spend for teams that hate budgeting around credit-pool refills.
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). Leadfeeder and Warmly require Zapier or custom code at this layer — a meaningful integration tax as AI-agent stacks mature.
We're upfront - every tool has strengths. Here's where Leadfeeder, Warmly, and Derrick each genuinely win.
Headline pricing rarely tells the whole story. Here's the real cost of running each tool for a year.
| Leadfeeder | Warmly | Derrick | |
|---|---|---|---|
| Starting price (monthly) | Free Lite forever · Visitor ID from €99/mo | $10,000/year | €0 (free) · €9/mo paid |
| Annual cost (base) | ~€1,188/yr | ~€120/yr | €0/yr free · ~€108/yr paid |
| Free plan? | Yes - Lite plan free forever (100 companies/mo) | Free tier (limited deanon) | ✓ Forever - 100 credits/mo |
| Setup cost | Hours to days | Hours to days | 30 seconds via Marketplace |
| Switching cost | CSV export + retraining | CSV export + retraining | Zero - works alongside any stack |
💡 Most teams pay 2-5x more on add-ons (extra seats, phone credits, integrations) than on the headline base price. Derrick keeps everything in one transparent tier.
