About Me

Hi, I’m Sinmi Ariyibi! A strategy-minded business analyst who turns complex data into clear, actionable decisions.

Recently, I supported GTM execution at Pronghorn (Edmond’s Honor) by translating market and pricing analysis into data-informed sales decks and designing SOPs that improved pipeline visibility and execution speed. In parallel, I lead finance operations for The Rock Nation, where I manage budgets and reporting through clean, reliable Excel systems that support leadership decision-making.

I’m strongest at the intersection of analysis + storytelling — framing the right questions, interpreting metrics, and turning results into narratives stakeholders can trust and act on. Tools: Excel, SQL, Tableau, Python, Power BI.
