IN CONVERSATION WITH LUSHANI MELLAWA KODITUWAKKU
HER STORY. HER STRENGTH. BY DR. SULOCHANA SEGERA
For Lushani Mellawa Kodituwakku, success has never been defined solely by titles or achievements. From leaving Sri Lanka three decades ago to study Economics in the United Kingdom to becoming one of the world’s most recognised experts in Commercial Due Diligence, her journey has been shaped by resilience, curiosity and an unwavering commitment to excellence. Today, she is the Founder and Managing Director of Luminii Consulting and a Non-Executive Director at Judges Scientific PLC. Having advised more than 500 businesses worldwide, she has built a reputation as a trusted strategist and leader in a highly specialised field. Yet, beyond her professional accomplishments, she remains deeply committed to family, philanthropy and empowering others. In this conversation, Lushani reflects on the challenges she overcame, the values that guide her leadership and the lessons she hopes to pass on to the next generation of women determined to create meaningful change.
What inspired your decision to move to the UK and pursue a career in economics, strategy and commercial due diligence?
My journey was shaped by both opportunity and a lifelong fascination with business. Growing up with entrepreneurial parents, I spent a great deal of time around their business, observing customers, trade fairs and day to day operations. That early exposure sparked my interest in economics and strategy. I moved to the UK after receiving a partial academic scholarship to study Economics. While I initially planned to return to Sri Lanka, life took a different course. Breaking into the professional world was not easy, particularly as someone born and educated in Sri Lanka. However, perseverance eventually led me to consulting, where I discovered my passion for solving complex business challenges. Later, at KPMG, I was introduced to Commercial Due Diligence, a field that immediately resonated with me. The opportunity to help investors make informed decisions and support businesses on their growth journeys was both intellectually stimulating and rewarding.
Commercial Due Diligence is a highly specialised and traditionally male dominated field. What attracted you to this profession?
What attracted me most was the impact of the work. Commercial Due Diligence allows you to influence important investment decisions and help businesses unlock growth opportunities. I also enjoy the variety. Every assignment exposes you to different industries, business models and challenges, which means there is always something new to learn. The profession demands objectivity, integrity and trust, qualities I value deeply. While it has traditionally been male dominated, that never discouraged me. Early in my career, I was often the only woman in the room. I soon realised that credibility comes from the quality of your thinking and the value you bring. Over time, those experiences strengthened my confidence and reinforced the importance of authenticity and expertise.
As the only woman globally recognised as a leader in Commercial Due Diligence, what challenges did you face and how did you overcome them?
Building a leadership position in a specialised field is challenging under any circumstances. Doing so in a country where I was not born, without established networks, added another layer of difficulty.
I chose to view challenges as opportunities rather than obstacles. Many limitations are created by fear and self-doubt, so I focused on developing a positive mindset and believing that success was possible. Resilience was equally important. There were disappointments and setbacks, but I never allowed them to define me. Instead of pursuing recognition or titles, I concentrated on delivering my best work. Over time, excellence and consistency created opportunities. Most importantly, I stayed true to my values. Integrity, respect and authenticity have always guided my decisions, and those principles helped me build trust and credibility throughout my career.
What inspired you to establish Luminii Consulting in 2017?
Before founding Luminii, I had the opportunity to build and lead practices at Grant Thornton and Neovian Partners. Those experiences were invaluable, but I always wanted to create a business that reflected my own values. I wanted to build a firm where people genuinely enjoy coming to work, where collaboration replaces politics and where individuals feel valued and supported. Creating a culture rooted in integrity, respect and shared purpose was central to my vision. I also wanted our clients to experience that same commitment. Regardless of the size of the engagement, we approach every project with passion, rigour and dedication. Luminii was created to combine excellence in strategy and Commercial Due Diligence with a deeply human approach to business.
Having advised more than 500 businesses worldwide, what leadership qualities do you see in organisations that succeed?
The most successful organisations are led by people who build trust. Strong leaders demonstrate integrity, authenticity and empathy while creating environments where individuals feel empowered to contribute. They foster collaboration rather than relying solely on hierarchy and create a shared sense of purpose throughout the organisation. These qualities strengthen resilience, improve decision making and enable teams to perform at their best. Ultimately, successful leaders recognise that people are at the heart of every thriving business.
You were invited to co-author the first global best practice guideline for Commercial Due Diligence. What did that recognition mean to you?
Personally, it represents the legacy I will leave behind. To contribute to a global framework that will guide future generations of practitioners is incredibly meaningful. When the ICAEW Corporate Finance Faculty invited me to participate, I was genuinely humbled. As a young girl growing up in Sri Lanka, I could never have imagined such an opportunity. Professionally, it validates years of dedication and perseverance in a demanding field. It is a reminder that commitment and hard work can lead to extraordinary outcomes.
Luminii donates seven per cent of its profits to charitable causes. Why is creating impact beyond financial success important to you?
I believe the true measure of success extends far beyond financial performance. Profit is essential, but it should not be the sole definition of achievement. Businesses have a responsibility to contribute positively to society and the communities they serve. When organisations use their success to uplift others and address broader needs, they create a legacy that lasts far beyond commercial results.
At Luminii, donating a portion of our profits reflects that philosophy. As we grow, we want to help others grow too, creating a more meaningful and sustainable form of success.
Many women struggle with self-doubt despite their capabilities. Have you experienced imposter syndrome?
Yes, many times. Self-doubt is a natural human response, particularly when you are pushing yourself beyond your comfort zone. What helped me was learning to observe my thoughts rather than identify with them. Self-doubt is simply a thought, not a fact. Once you recognise that distinction, it becomes easier to move forward. I also learned to stop comparing myself with others. Much of imposter syndrome comes from comparison. When you focus on doing your best rather than trying to be perfect, the pressure begins to fade. For me, confidence comes from self-awareness, effort and authenticity rather than external validation.
How have your Sri Lankan values shaped your approach to family life while building a global career?
My cultural values have always been my anchor. Being a good wife, mother, daughter and friend has remained my first priority, and those values have guided many of my decisions. I have worked hard to ensure my children remain connected to their roots despite growing up in the UK. Family remains central to my life, and I still speak to my parents every day. Balancing family and career has required discipline and sacrifice, particularly without an extended support system nearby. However, I have no regrets. The roles we play outside work teach us empathy, patience, resilience and emotional intelligence, qualities that also make us better leaders.
What does “Her Story. Her Strength.” mean to you?
To me, it is a reminder that every woman’s journey is unique and valuable. Our strength comes from embracing our individual experiences, both the triumphs and the challenges. My message to the next generation of women is simple. Always do what is right, even when it is not the easiest path. Stay authentic, celebrate the success of others and never allow fear or comparison to limit your potential. Focus on becoming the best version of yourself, contribute with purpose and continue uplifting those around you. In the end, true success is not only about what you achieve, but also about how you grow and the positive impact you leave behind.
