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:
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.
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.
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.
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 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.
