Jona Ridderskamp works analytically, directly and with palpable curiosity. As CEO of suresecure GmbH, he combines leadership, entrepreneurship and over ten years of experience in IT security with a clear ambition:

Constant change
is a must.

With his highly technical background and a decade of experience, he now focuses above all on development, security crises and entrepreneurship. Creating orientation, assessing risks, enabling decisions. Entrepreneurially and politically. Not just reacting, but thinking ahead.

Jona brings technical depth and strategic thinking, and says openly when something isn't right. In talks and podcasts he explains complex topics sharply and without rhetorical ballast. Passing on knowledge is an essential part of being a leader.

Always with the goal that the impulses remain, even long after he's left the room

Founder & Managing Director, Appleute GmbH
“Jona has been my sparring partner for over a year now — the only one who consistently asks me the uncomfortable questions instead of telling me what I want to hear. He has been through the same entrepreneurial upheavals himself and thinks along on every level: from sharpening our target audience to the shareholder agreement and equity split, all the way to liquidity planning. His push for focus — letting go of weak revenue rather than chasing it all — got us to break-even and on course toward our first million. Honest, direct, and every single time it moves me forward.”
Marcel Hoppe
Streamer & Founder, tinNendo
“As a creator, it feels like you do everything yourself – and still never the right thing first. Jona helped me turn my reach into a business that actually holds up: clear numbers, real priorities, and income that doesn't wobble with every algorithm update. He takes me seriously as an entrepreneur, not just a streamer. For the first time, I'm scaling my thing instead of just feeding it.”
