Welcome to another episode of Category Visionaries — the show that explores GTM stories from tech’s most innovative B2B founders. In today’s episode, we’re speaking with Marina Segal, CEO & Co-Founder of Tamnoon, a cutting-edge cloud security platform that has successfully raised over $5 Million in funding.

Here are the most interesting points from our conversation:

  • Early Experiences Shape Future Paths: Marina’s initial years in Israel and service in the IDF taught her vital lessons in adaptability, language, and equality. Despite her niche role within the IDF, it laid the groundwork for her passion in compliance and frameworks, influencing her career trajectory.
  • Cultural Adjustments and Learning Curves: Moving to the US, Marina faced the challenge of adapting to a new work culture, learning the subtleties of communication and professional interaction. This experience sharpened her interpersonal skills and played a crucial role in her decision to dive into the startup ecosystem, drawing her closer to the Israeli community.
  • Driven by Process Optimization: Marina’s journey into cloud security was motivated by her desire to automate and optimize compliance assessments and risk management processes. Her work at Deloitte and the transition to a tech startup stemmed from her passion for reducing manual workload through innovative solutions.
  • Finding Inspiration in Leadership: Marina credits her grandmother and a mentor from Deloitte as significant inspirations in her life. Their leadership styles, emphasizing humility, approachability, and the ability to manage stress while fostering a sense of equality and peer respect, greatly influenced her approach to leadership and problem-solving.
  • Tamnoon’s Unique Value Proposition: Tamnoon aims to bridge the gap between cloud security detection and effective remediation. By focusing on the next step beyond just identifying security issues, Tamnoon seeks to offer scalable solutions for remediation and prevention, addressing a critical need in the cloud security space.
  • The Significance of Team Building: The co-founding journey of Tamnoon underlines the importance of partnership and team dynamics. Marina’s previous collaboration with her co-founder at another startup highlighted the value of shared principles, conflict resolution, and the ability to work towards common goals.



Embrace Cultural Diversity and Adaptability:

Marina's transition from Ukraine to Israel and eventually to the US underscores the importance of adaptability in diverse work environments. For founders, especially those in global or multicultural settings, understanding and embracing cultural nuances can significantly improve team dynamics and business negotiations.

Leverage Personal Experiences for Professional Growth:

Marina's service in the IDF and her unique career path highlight how personal experiences can shape professional expertise, especially in niche areas like compliance and frameworks. Founders should consider how their unique backgrounds can offer fresh perspectives and solutions in their industry.

Prioritize Process Automation and Efficiency:

Marina's passion for minimizing manual tasks through technology is a crucial reminder for founders to continually seek ways to optimize operations. Investing in cloud security or other tech solutions to automate and streamline processes can drive significant long-term benefits for startups.

Cultivate Leadership that Promotes Equality and Team Collaboration:

Inspired by her grandmother and a mentor, Marina values leadership that treats team members as equals and fosters a collaborative environment. Founders should strive to create a company culture that encourages open dialogue, mutual respect, and shared success.

The Critical Role of Team Composition in Startup Success:

The co-founding partnership between Marina and her colleague showcases the importance of having the right team in place from the outset. Founders should prioritize finding partners and team members who not only share a common vision but also complement their skill sets and work styles. This can be the cornerstone of navigating challenges and scaling the startup effectively.
