ClayMBA

ClayMBA is not a traditional lead generation agency - it's a specialized training program built around mastering Clay, the data enrichment and automation platform. Founded by Hans Dekker, who brings over 5,000 hours of hands-on experience and more than 1 million cold emails sent, the course offers a structured, no-fluff curriculum for sales professionals who want to build scalable outbound systems. Based in Spain, the small team of 2-10 employees focuses entirely on education rather than client campaign management.

The core offering is a 10-module course that covers everything from basic Clay setup to advanced AI-driven email personalization and data enrichment. Each module includes test assignments, and students gain access to bonus materials such as ready-to-use Clay playbooks, templates, and curated data sources. The curriculum is designed to be immediately applicable, helping SDRs, agency owners, and revenue leaders turn Clay's capabilities into real pipeline results.

Pricing is straightforward: under $2,000 per course, which positions it as a mid-range investment for professional development. Compared to hiring a full-service agency or buying multiple point solutions, this is a cost-effective way to build in-house expertise. The course is delivered as an one-time purchase, and the materials are updated to reflect Clay's evolving feature set.

ClayMBA is best suited for individuals and teams who already have some outbound experience and want to level up their technical skills with Clay. it's less ideal for companies looking for a done-for-you service or for complete beginners who need hand-holding on basic sales concepts. The program assumes a baseline familiarity with cold outreach and a willingness to work through technical workflows.

Client feedback consistently praises Hans Dekker's depth of knowledge and the practical nature of the course. Testimonials note that the assignments force real application, and the bonus templates save hours of trial and error. The main limitation is that the course is self-paced and does not include ongoing support or live coaching, which some learners may miss.

Overall, ClayMBA fills a specific niche: it's one of the most thorough Clay training programs available from a practitioner with proven results. For any sales team or agency that relies on Clay for outbound automation, the course can pay for itself many times over by reducing ramp time and improving campaign performance. it's a smart investment for those ready to go deep on the tool.
