At Sigma Software, we believe that strong leadership is built on expertise, resilience, continuous growth, and the ability to create opportunities for others. This year, two of our leaders received prestigious international recognitions, highlighting both their individual achievements and the strength of female leadership across our organization.
Katherine Tuluzova Marked at WOMEN IN TECH® Global Awards 2026
The recognition of Katherine Tuluzova, CEO of Sigma Software, and Hanna Abdelhamid, Head of Sigma Software Canada, reflects more than professional success. It demonstrates the impact women leaders have on shaping businesses, driving innovation, and inspiring the next generation of technology professionals.
Katherine Tuluzova Marked at WOMEN IN TECH® Global Awards 2026
Katherine Tuluzova, CEO of Sigma Software, has been recognized in the North America Global Leadership category of the WOMEN IN TECH® Global Awards 2026, a prestigious international program celebrating outstanding achievements of women across the technology sector. The recognition adds to Katherine’s growing list of industry achievements, following her 2025 WOMEN IN TECH® Chief in Tech Leader of the Year Award and further highlighting her impact on the global technology community.
Katherine’s journey is a powerful example of professional growth driven by talent, determination, and vision. She joined Sigma Software more than 17 years ago as a Junior Java Developer and steadily progressed through leadership roles, helping expand the company’s presence across North America and Latin America before becoming CEO in 2025.
Today, Katherine leads a global company operating in more than 20 countries, guiding Sigma Software through its next stage of growth. Under her leadership, the company continues to invest in AI adoption, engineering excellence, global expansion, and long-term client partnerships while maintaining a strong focus on people development and company culture.
Beyond business results, Katherine actively contributes to the global technology community. She serves in leadership roles within Prebid task forces and in the Board of Directors of IAB Tech Lab, represents Sigma Software at international industry events, and actively supports greater gender balance in technology through Femmegineering, the company’s initiative dedicated to empowering women in tech.
Outside of work, Katherine is also a triathlete and multiple-time Ironman 70.3 finisher, bringing the same discipline, endurance, and determination to leadership that she demonstrates in sport.
Being recognized among technology leaders from around the world is a meaningful acknowledgment of Katherine’s influence, leadership, and contribution to the global tech industry.
Hanna Abdelhamid Named Among Canada’s Most Powerful Women
At the same time, Hanna Abdelhamid, Head of Sigma Software Canada, has once again been recognized among Canada’s Top 100 Most Powerful Women by WXN, earning a place in the Top 10 of the Executive Leaders category for the second time.
The award recognizes women whose leadership creates meaningful impact across businesses, industries, and communities throughout Canada.

In parallel with her business leadership responsibilities, she actively advocates for greater representation of women in technology and supports professional growth opportunities for future female leaders.
Hanna regularly speaks at international industry events, mentors women advancing from middle management into senior leadership positions, and contributes to our Femmegineering initiative through educational, mentoring, and community initiatives. She also is a host of the Femmegineering: Women of Influence podcast, available on Spotify, Apple Podcasts, and YouTube Podcast, where she highlights the experiences and achievements of accomplished women leaders from around the world.

Leadership That Creates Opportunities
These recognitions reflect more than individual achievements. They demonstrate Sigma Software’s long-standing commitment to building an inclusive environment where talent can grow regardless of gender, background, or geography.
Through initiatives such as Femmegineering, leadership development programs, mentorship, and equal opportunities policies, Sigma Software continues to foster a culture where women can thrive, lead, and shape the future of technology. Our efforts in this area were recognized – Sigma Software was named the Best Workplace for Women in Tech at Women in Tech Global Awards 2025 by WomenTech Network, one the world’s largest community for women in tech with more than +13,000 ambassadors in 179 countries.
Today, women hold nearly half of management positions within the company, while Femmegineering continues to inspire and support women in technology through education, community-building, mentorship, and visibility of female role models.
As we celebrate these achievements, we also celebrate the broader community of women across Sigma Software who lead teams, drive innovation, mentor colleagues, and contribute to the company’s continued growth every day.
Congratulations to Katherine and Hanna on these remarkable accomplishments. Their leadership continues to inspire our teams, strengthen our company, and demonstrate the impact women make across the global technology industry.
