Customer Success Manager (CSM) Expansion… at Riot Security · Paris

We're a product-first team on a mission to help grow the cybersecurity culture 🔐

We want to instill cybersecurity good practices to employees in a way that's actually effective, and entertaining enough so that employees don't feel like they're working. Think Duolingo but for cybersecurity.

We created a platform to easily rollout a cybersecurity awareness program: the platform sends chat-based 4-minutes long courses to teams. Following the courses, the other side of the platform simulates phishing attacks, to prepare employees to face hackers, but in a safe environment.

Created in 2020, Riot has raised $45m with leading investors (Y Combinator, Left Lane, Base10, Funders Club and First Capital) and is now protecting more than 2,000,000 employees in over 2,000 companies (including Intercom, Deel, and Deezer) all over the world.

Cybersecurity is everywhere. It's impacting everyone, everyday, and it's becoming the number one risk to any organization, whether it's a small business or a big firm. Yet, the cybersecurity culture in most companies is a disaster. Hackers are leveraging this by targeting the weakest link: the employees. We're on a mission to fix that.

You will join the Customer Success team. Your main focus will be to support our clients in getting the most value out of our products.

We operate across 2 client segments: Enterprise and Mid-Market.

• Enterprise covers companies with more than 2,000 employees and relies on a more consultative/personalized, relationship-driven approach with a dedicated portfolio.

• Mid-Market covers companies with less than 2,000 employees and relies on a more personalized, relationship-driven approach with a dedicated portfolio.
