Behind the Ski’s

We wrapped up January with our annual kick-off, bringing the entire team together in one place with three key objectives: reflect, inspire and connect. 

Over two days, we explored our 2025 strategy and celebrated new company values to ensure we continue to build a world class bug bounty platform. 

After looking up to the future, we had to bring the balance by sliding (and tumbling) down the slopes... 🫠 

After recovering from the hype of the kick-off event we’re energized and inspired ready to hit the ground running for the year ahead! 

Watch the kick-off event highlights video here 📺
