At Nexal, we train data analysts through hands-on projects that simulate real Business Intelligence and AI systems used in companies.
Next Cohort Starting 1st September, 2026
The Big Problem
Most aspiring data analysts learn tools like SQL and Power BI.
But companies don’t hire people who only know tools.
They hire people who can build real data systems and deliver insights.
That’s why many analysts stay stuck in tutorials without getting hired.

• Data ingestion
• Data transformation
• Data modeling & Data Warehousing

Meet the FounderErick Mwangome
BI & AI Developer // Instructor
I don’t just teach tools. I teach how to build real-world systems that work at scale.There’s a massive difference between running a script on your laptop and engineering a full BI or AI workflow that processes real data, automates pipelines, and delivers actionable insights.I founded Nexal because I saw too many talented analysts and aspiring data professionals getting stuck in tutorial hell, lacking the practical, portfolio-ready experience companies actually expect.Our programs simulate real-world analytics and AI workflows: you’ll work with the same tools, face the same challenges, and solve the same problems you’ll encounter in your first role, so you graduate job-ready and confident.
