Stephan Kulik

Editor-in-Chief, AI Sales Stack

Role

I run editorial operations for AI Sales Stack — independent reviews of AI sales tools across prospecting, engagement, conversation intelligence, and ABM. Every review is held to the same standard and carries my byline.

Evaluation methodology

Each platform is evaluated against primary sources — independent review platforms (G2, Capterra, Trustpilot), official pricing pages, product documentation, and vendor changelogs — and scored on a consistent set of criteria: pricing and value, data and feature quality, AI capabilities, integrations, and the limitations users report most often. Reviews are re-validated every 90 days with current pricing and satisfaction data. Where a review includes first-hand testing, the methodology and findings are documented on that review.

Compliance

Where a review involves outbound testing, it is run only on opted-in lists, in line with CAN-SPAM, GDPR, and CASL — never on cold-scraped data.

Editorial focus areas

  • Sales intelligence platforms (ZoomInfo, Apollo, Clay, Cognism, Seamless.AI, Lusha)
  • Sales engagement (Outreach, Salesloft, Apollo, Reply, Instantly, Smartlead)
  • Conversation intelligence (Gong, Chorus, Clari)
  • AI ABM (6sense, Demandbase)
  • Autonomous AI SDRs (Artisan, 11x, AiSDR, Regie)
