## About

Most B2B software doesn't churn because the product is weak. It churns because nobody inside the customer got it adopted, and nobody on the vendor side noticed until the renewal.

I'm Jonny, Head of Customer Success and Account Management with over a decade in SaaS and Cybersecurity, including customer-facing roles at SecureFlag, Secure Code Warrior and Immersive. I've built and scaled CS functions selling to developers, AppSec teams, and CISOs.

I work with:

- B2B SaaS leaders (founders, CS and AM heads) who need a stronger onboarding, adoption, renewal, and expansion motion, especially when selling to technical buyers.

- Cybersecurity companies facing the same challenges with a harder buyer: developers, AppSec teams, and CISOs.

- Security leaders who need a Threat Modelling, Secure Coding, or Security Champions programme actually adopted and changing the culture of your Engineering and Security teams.
