3 core reasons SDRs and ops teams switch to Derrick. Click to expand each.
01
Real-time validation and enrichment, without LinkedIn limits
＋
Real-time validation and enrichment without LinkedIn limits is where Derrick shines, addressing Kaspr’s reliance on LinkedIn data quality and Waalaxy’s LinkedIn-driven outreach by delivering native Google Sheets enrichment with 50+ attributes and real-time email validation. Unlike Kaspr and Waalaxy, which depend on LinkedIn data or automate outreach with limited enrichment, Derrick offers the web app (plus Sheets, Claude, API) access and multi-attribute profiling without LinkedIn constraints. This translates to faster lead qualification and improved deliverability, reducing research time by 5-10 hours per month and boosting accuracy across contacts and companies. In practice, teams can validate emails in real time while enriching a profile in a single sheet, enabling immediate, reliable outreach.
02
Seamless multi-channel data with integrated AI scoring
＋
Kaspr and Waalaxy primarily rely on LinkedIn-based data or limited multi-channel signals, which leaves gaps in cross-platform visibility and AI-driven scoring. Derrick differentiates by delivering seamless multi-channel data with integrated AI scoring that aggregates signals beyond LinkedIn and applies automated scoring and segmentation. This translates to faster, more accurate prioritization and better targeting across channels, reducing wasted outreach and boosting conversion rates by up to 20-30% in pilot teams. With Derrick, you get a unified view and actionable AI insights in real time, not just isolated LinkedIn data points.
03
Unified data quality with enterprise-grade cleaning and deduplication
＋
Kaspr and Waalaxy both rely on surface-level data or LinkedIn-centric sources, leaving gaps in deduplication and enterprise-grade cleaning when scaling beyond profiles. Derrick delivers unified data quality with robust cleaning and deduplication across 50+ attributes, removing duplicates and normalizing records directly in the web app (or in Google Sheets, Claude and the API). This translates to measurable gains: up to 20–30% reduction in duplicate outreach and a 15% boost in deliverability due to cleaner contact profiles. With monthly rollover credits and native enrichment, Derrick keeps data pristine without exporting, enabling faster, compliant multi-channel outreach.

Honest comparison
What each tool does better
We're upfront - every tool has strengths. Here's where Kaspr, Waalaxy, and Derrick each genuinely win.
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.
Best for: EU-focused SDRs needing LinkedIn phone numbers
Kaspr offers a credit-based pricing model with an entry-level free tier and paid plans starting at a modest monthly credit bundle; detailed breakdowns cover scale, add-ons, and enterprise options. See full pricing breakdown for complete details.
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.
Best for: Solo prospectors testing LinkedIn outbound for the first time
Waalaxy offers starter plans with affordable entry tiers and scalable credits for LinkedIn prospecting, with a detailed pricing breakdown available on the pricing page. See full pricing breakdown for complete details and options.

What’s the Derrick vs Kaspr main difference for data enrichment?
+
The main difference lies in enrichment scope and workflow integration. Kaspr specializes in real-time phone and email verification with strong CRM integration, making it excellent for contact-level accuracy. However, it lacks comprehensive firmographic data and requires manual validation for scale. Derrick, by contrast, delivers 50+ enrichment attributes per contact and company directly in the web app (or in Google Sheets, Claude and the API), including company intelligence, technographics, and AI-powered scoring with Claude and ChatGPT. Unlike Kaspr's verification-focused approach, Derrick provides deeper account intelligence while eliminating CSV exports and complex configurations. For teams needing both contact accuracy and multi-dimensional company data without leaving the web app or their spreadsheet, Derrick offers superior enrichment depth at a more flexible pricing model with rollover credits.
Is Derrick a better alternative to Kaspr for accuracy?
+
Derrick and Kaspr both prioritize contact accuracy, but they serve different needs. Kaspr focuses on real-time phone number verification with strong deliverability rates, making it ideal for phone-focused outreach. However, Derrick offers broader accuracy across 50+ contact and company attributes, including email validation, firmographic data, and intent signals-all natively in the web app (or in Google Sheets, Claude and the API) without requiring LinkedIn Sales Navigator or complex integrations. For teams needing comprehensive multi-dimensional accuracy beyond phone numbers, Derrick provides deeper enrichment with rollover credits and built-in AI validation, reducing manual verification overhead and improving overall campaign effectiveness.
Derrick vs Kaspr: which is better for pricing?
+
Derrick offers more flexible pricing than Kaspr with rollover credits that never expire on paid plans, meaning unused credits carry forward monthly without waste. Kaspr operates on a traditional credit consumption model where unused credits disappear each billing cycle. Derrick's pricing starts at €0 with a free tier of 100 credits requiring no credit card, while Kaspr requires paid commitment upfront. For teams seeking transparent, scalable pricing with genuine cost control and the ability to pause spending, Derrick's model provides superior value, especially when combined with its native web app, Google Sheets, Claude (MCP) and API integration that eliminates expensive third-party tools and subscription stacking.
Which has a better review overall, Derrick or Kaspr?
+
Based on overall reviews, Kaspr tends to receive positive feedback for its real-time phone verification, CRM integration, and LinkedIn-based prospecting, but users also note data accuracy gaps and limited multi-dimensional enrichment. Derrick, by contrast, is praised for its web app workflow (also in Google Sheets, Claude and the API), extensive enrichment (50+ attributes per contact or company), real-time email validation, and a broad ecosystem of integrations, all while eliminating CSV exports and LinkedIn dependencies. Taken together, Derrick often earns higher satisfaction for end-to-end data enrichment and workflow efficiency, whereas Kaspr shines for quick contact verification within a LinkedIn-centric prospecting setup. If you value comprehensive enrichment and seamless web-app-first operations, Derrick generally has the stronger overall review profile.
How does Derrick compare with Waalaxy in features?
+
Derrick differentiates from Waalaxy by operating natively in the web app (or in Google Sheets, Claude and the API), eliminating the need for external platforms or CSV exports, while Waalaxy requires dedicated campaign management outside your spreadsheet. Derrick provides deeper data enrichment with 50+ contact and company attributes, real-time email validation, and integrated AI scoring via Claude and ChatGPT, whereas Waalaxy focuses primarily on LinkedIn automation and messaging sequences. Additionally, Derrick's rollover credits and no credit card requirement for the free tier offer greater flexibility than Waalaxy's subscription model, making it more accessible for teams prioritizing data quality alongside outreach automation.
Can Derrick replace both Kaspr and Waalaxy effectively?
+
Derrick cannot be a drop-in replacement for Kaspr and Waalaxy on every dimension, but it can complement or replace specific gaps. Kaspr focuses on real-time contact verification and CRM-ready data, while Waalaxy shines in LinkedIn-based automated outreach. Derrick offers 50+ enrichment attributes, real-time email validation, the web app (plus Sheets, Claude, API), and powerful AI scoring, reducing manual research and enabling multi-step workflows without LinkedIn dependence. For teams needing deep, multi-channel outreach plus rich account intelligence, using Derrick alongside or after Kaspr/Waalaxy provides broader data depth and automation efficiency.
