Tech Scenes Unplugged with Yossi Appleboum, CEO of Sepio

"You have to make the mistakes—they cannot take the mistakes for you." — Yossi Appleboum, CEO of Sepio

In this episode of Tech Scenes Unplugged, Jeff James Martin sits down with Yossi Appleboum, CEO and Co-founder of Sepio, to explore the mindset and leadership it takes to build a deep-tech company from the ground up. Drawing on his experience in Israel’s Unit 8200 and multiple successful startup exits, Yossi shares the power of tension, the value of mistakes, and how to foster teams that argue fiercely and trust deeply.

Sepio’s unique approach to device risk management—leveraging physics, machine learning, and trafficless monitoring—has positioned the company as a leader in asset visibility and control across IT, OT, and IoT. Yossi breaks down what it takes to build a truly interdisciplinary team, how Sepio entered a skeptical market, and why it's not just about building the right product—it's about building the right team to bring it to life.

Whether you’re building in cybersecurity, scaling a startup, or evolving as a leader, this conversation brings clarity to the chaos of innovation.
