"Evening Power BI coaching was exactly what I needed. Helpazone tailored every session to my actual financial data. Professional dashboard delivered by the end of week 2."

BI training in Madagascar, the Indian Ocean and Africa

In Madagascar, sessions run in person in Fianarantsoa and Antananarivo, as well as on-site for organisations across all regions. Evening sessions (6pm-8pm, Monday to Saturday) let you follow the pathway without interrupting your professional activity.

Across the Indian Ocean (Comoros, Mauritius, Réunion, Seychelles) and Francophone Africa, the pathway is followed entirely remotely. The format stays identical: same exercises, same deliverables, same 6-month post-training support. Close time zones make live sessions practical rather than recorded ones.

Power BI and Tableau run locally once installed, which makes the pathway workable even on an intermittent connection. Working files are provided in advance to limit downloads during sessions.
