Hi, I'm Dionne Mayienga

I’m the founder and principal consultant of Subena Growth Advisory. Thing is, I’ve seen far too many brilliant ideas get ‘stuck on the shelf.’ So after nearly 13years in big corporate financial services, I am on a mission to help guide 200 great ideas beyond concept to commercialization over the next 10years. My expertise is in market penetration, expansion and diversification strategies for financial services and tech companies. One of the things that makes me stand out is how I integrate consumer psychology nuances with cold hard data to design performance dashboards that address specific growth challenges. I’m passionate, pragmatic and persistent with new ideas.

We are a boutique growth strategy firm that provides CMO-as-a-Service for early-stage to mid-maturity companies struggling with commercialization traction. We are a collective of experts in commercialization strategy focused on fintech, financial services, and tech industries. Our approach integrates marketing, sales, product development, and customer experience into unified strategies that drive both immediate results and long-term growth. We focus on processes and frameworks that transform customer interactions into revenue streams.
