CRM Integration Flow
SeamlessAI offers instant native CRM enrichment. CASTANET relies on Zapier or Google Sheets for profile exports.

If your sales stack relies on Salesforce, SeamlessAI integration is faster and more seamless right out of the box.
User Trust & Support
CASTANET has strong reviews (4.3/5) and less friction. SeamlessAI's low rating (2.5/5) is driven by billing and support grief.
CASTANET users praise its reliable automation and transparent, predictable lead flow. The 7-day trial offers a low-risk entry point. SeamlessAI users frequently cite major pain points surrounding hidden auto-renewal terms. Many reviews mention difficult cancellations and sluggish customer support. CASTANET appears to be a more customer-friendly and trustworthy partner based on collective feedback. SeamlessAI's value is often undermined by administrative issues. If long-term billing peace of mind is crucial, CASTANET is the safer and more highly rated option among users.
Pricing Structure

CASTANET offers Basic ($99/month) up to Team ($399/month) plans based on included LinkedIn profiles (1-3). It features a simple 7-day free trial. SeamlessAI provides a persistent Free plan with 50 credits for one user. Paid plans often run per-user, with an Enterprise tier allowing unlimited users. For a small test, SeamlessAI's free plan is invaluable for long-term data verification. CASTANET requires committing to a subscription after one week. However, SeamlessAI's reported hidden auto-renewal terms mitigate the perceived value of its low starting price point.

Our Verdict
Choosing between CASTANET and SeamlessAI is a classic process vs. data volume trade-off. CASTANET is the safer choice if you need reliable pipeline automation and transparent business practices. SeamlessAI is best suited for those needing huge contact lists, but buyer caution is essential. CASTANET’s superpower is its steady, 24/7 LinkedIn lead generation engine. CASTANET provides clear 'why fit' signals, using schools and groups for smart personalization. It easily exports lead profiles to your CRM via Zapier or Google Sheets. Importantly, CASTANET users report high satisfaction and reliability (4.3/5 rating). SeamlessAI's strength lies in its massive, real-time B2B contact database. SeamlessAI can enrich your CRM fields in seconds using data from 1.3 billion contacts. It also offers powerful native integrations for Salesforce and HubSpot for speed. However, SeamlessAI reviews repeatedly flag issues with data accuracy and non-transparent auto-renewal contracts. Your decisive factor should be trust backed by user reviews.
