‎If you have ever wondered what happens when curiosity meets numbers and empathy meets data, you will find your answer in the story of Oluwatomisin Olorunmaiye (Tomisin), a man who has quietly built a reputation for turning complex analytics into clear, actionable insights that drive real-world impact.
‎
‎Tomisin’s journey into digital analytics started at Playhouse Communications Ltd, one of Nigeria’s multiple award-winning digital agencies. He is, however, quick to note that his love for numbers started far before he ever knew what digital analytics was. Growing up in Lagos, he was always fascinated by numbers and patterns hidden in them. He speaks about having favourite numbers in 9 and 16, primarily because they are 2 unique numbers. The former is the only number whose digits in all its multiples always add up to itself, and the latter for its importance and appearance in Computing.

‎This love for numbers ultimately led him to digital analytics. Early on, he started making sense of website clicks and campaign metrics, connecting dots others did not see and understanding how user behaviour translates to conversions. “We were not just looking at numbers,” he often says with a grin, “we were telling stories with data, stories that helped brands make smarter decisions and develop data strategy.”
‎
‎At Playhouse, he helped shape digital strategies for multinational clients to ensure every campaign was not just creative but also measurable and meaningful. His work contributed to campaigns that earned recognition both locally and internationally, proof that when creativity meets analytics, magic happens.
‎
‎Today, Tomisin has taken that same data-driven passion across continents to his role as Senior Digital Analyst at Great Ormond Street Hospital (GOSH) Charity in London. There, he leads the charge in building a smarter, more insight-driven approach to fundraising and donor engagement. From improving donation funnel tracking to refining user journeys across multiple subdomains, his work ensures that every marketing pound spent by the charity creates more impact for children’s healthcare.

‎But his story is not just about dashboards and KPIs. It is also about people. Beyond his day job, he dedicates time to mentoring upcoming digital analysts, helping them navigate the often intimidating world of data analytics. Whether through online communities, informal training sessions, or one-on-one guidance, Tomisin is passionate about growing the next generation of data talent, especially those from underrepresented backgrounds.
‎In his words, “impossibilities are just unexplored possibilities.”
‎
‎It is this mix of technical brilliance, humility, and purpose-driven work that sets Tomi apart. From the buzz of Lagos’ advertising scene to the heart of one of the UK’s most respected charities, his story is proof that analytics is not just about numbers; it is about making impact visible.
‎
‎If his track record is anything to go by, he is simply not done yet. The world of digital analytics may be fast changing, but one thing is certain: wherever strategy meets storytelling, you will probably find him somewhere nearby, spreadsheet open, smile on his face, and a new insight waiting to be discovered.
