CURSOR 3 core reasons SDRs and ops teams switch to Derrick. Click to expand each.
Real-time verification without manual overhead is where Kaspr and Surfe fall short, as both rely heavily on manual checks or single-source data from LinkedIn, risking delays and gaps in validation. Derrick delivers true real-time verification directly inside 100% native Google Sheets, eliminating manual triage and exporting steps. With Derrick, teams gain instant accuracy for emails and contact data, reducing outreach friction and boosting deliverability by up to measurable margins. For quick wins, you can validate records on-the-fly during lead research, without leaving your workflow.
Kaspr and Surfe rely on single-source data or limited enrichment, which leaves gaps in cross-platform accuracy. Derrick App unifies enrichment across multiple sources inside 100% native Google Sheets, ensuring consistent, corroborated data instead of siloed signals. You gain a measurable uplift in data completeness and reliability, with up to 50+ attributes per contact and monthly credit reporting that reduces mismatches; real-time validation also improves deliverability. For quick workflows, Derrick consolidates company and contact signals in one place, avoiding manual cross-checks and exports.
Kaspr and Surfe depend on LinkedIn-centric data for enrichment, which limits their ability to offer full, multi-source depth without relying on LinkedIn. Derrick provides full-featured data enrichment without LinkedIn dependency oversight by pulling 50+ attributes across company and contact records directly in Google Sheets, without requiring a LinkedIn integration. This results in a tangible efficiency gain, with teams saving 5-10 hours per month and achieving more complete profiles than LinkedIn-reliant tools. Derrick also offers re-usable credits and native validation to ensure ongoing data quality in a single, Sheets-native workflow.
