In a continent bursting with entrepreneurial energy yet struggling with visibility and systems, Sunday Samuel Chibuikem is bridging the gap. As a digital marketing strategist and founder of Dgazelle Digital, he’s not just helping businesses show up online; he’s helping them grow up. From tech startups and nonprofits to oil & gas corporations and international institutions, Sunday has become the go-to strategist for building digital systems that attract, convert, and retain customers, profitably and predictably.

From a Local Learner to Global Strategist
Sunday’s journey began with curiosity and a computer. His first professional training was in website design at SOUTECH, one of Nigeria’s leading IT institutions. But that was just the beginning. Over the years, he’s gone on to earn multiple certifications in digital marketing, strategy, Facebook, and Google ads mastery from notable global institutions, including DigitalMarketer (USA), Google, Facebook, and Udemy.
Rather than just chasing trends, he immersed himself in learning systems that integrate content, email, advertising, automation, SEO, and conversion science, so clients don’t just “look good online,” but actually make money online.
Driving Growth Across Industries and Borders
Today, Sunday leads Dgazelle Digital, a growth-focused digital marketing and tech agency serving clients in Nigeria, Ghana, the U.K., the U.S., Canada, Australia, and Dubai.
He has worked extensively across sectors, with tech and non-tech startups, NGOs, academic institutions, and corporate organizations, including those in the oil & gas industry. One of his most prominent engagements has been as the Digital Marketing and Brand Manager for London Academy Business School (LABS), an international academic institution with a presence in London, Lagos, and Dubai. There, Sunday led multi-channel campaigns that expanded LABS’ market presence, built brand authority, and increased student enrollment across markets.
From building full-funnel systems for e-commerce brands, to executing public sector digital initiatives, Sunday’s approach is always the same: use strategy, not noise.
His agency’s efforts earned them the MEA Markets International African Excellence Award (2023) as Emerging Digital Marketing Agency of the Year – Nigeria.
Under Sunday’s leadership, Dgazelle has helped businesses scale from zero to $80,000+ in revenue within months, partnered with public institutions on digital bootcamps, and signed brand ambassadors like Nkem Offonabo and industry voices like Dr. Glory Edozien.
Beyond Business: Youth Empowerment and Community Impact
But Sunday’s influence is not limited to client work. A former President of Jamie Pajoel International (Bayelsa Chapter), he organized a State Youth Assembly that brought together over 200 emerging leaders in Bayelsa to learn business, leadership, and innovation.
His passion for impact inspired the first-ever Digital Innovation Conference at his alma mater, Federal University Otuoke, a milestone event sparked by a private bootcamp he had hosted on campus earlier. Since then, he has been invited to speak and train at various platforms, impacting over 10,000 individuals online and offline through masterclasses, workshops, and digital campaigns.
He also convened the 10X Business, Sales & Growth Conference, a high-impact event that has equipped 1,000+ entrepreneurs and professionals with the tools to grow and scale their ventures.
“No dream is too big, and no dreamer is too small,” Sunday says, a quote that mirrors his approach to work, mentorship, and the future of Africa’s digital economy.
Building Africa’s Next Generation of Digital Giants
Sunday’s life mission is clear: help people and businesses win using digital systems. Whether it’s installing a growth marketing engine for a startup or equipping students with real-world skills, his focus is the same, drive meaningful, measurable growth.
As Africa races toward a digital future, leaders like Sunday Samuel Chibuikem are ensuring the continent is not just connected, but strategically competitive
