Great Customer Success careers aren't found. They're built.
From individual classes to certifications to team-wide training programs, The Success League delivers learning that transforms how CSMs, CS leaders, and their teams perform.
Most CS training doesn't go deep enough.
Customer Success professionals at every level learned by doing, from CSMs navigating their first renewals to leaders building teams without a blueprint. The occasional class or conference session filled some gaps, but it was never enough. Now CS is expected to drive retention, expansion, and revenue, and that takes more than awareness. It takes structured, skills-based learning that changes how people and teams actually perform.
We've been building Customer Success skills for more than a decade.

The Success League was founded by CS practitioners who lived the skills gap firsthand. Since then, we've trained over 10,000 Customer Success professionals at over 500 B2B technology companies, with curriculum built and taught by people who have actually done the work. Deep, structured, and practical is the only kind of training we offer.
“The Success League program was incredibly valuable for our team. Our instructor gave thoughtful care and attention to our unique challenges, coaching us to lean into our strengths while helping us grow in areas that needed improvement. We’re leaving the program feeling more equipped to leverage relationships through customer success and account management to drive expansion and cross-sells.”

The Success League offers two certifications: CSM Certification and CS Leadership Certification.

Certification is how you prove it.
Our CSM Certification aligns with the Customer Success Association Competency Standard.
“The Success League's CSM Certification was a game-changer for me. The hands-on learning and small group interactions made it easy to quickly understand and apply key concepts. The program directly contributed to my growth and helped me earn a promotion within 10 months of starting my role. Highly recommend it to anyone serious about advancing in customer success.”
