Charles Schwab:
Put data to work.

Before Tableau Prep our team would spend hours and hours making sure that our data sources were clean and organized, just to make sure that our analysis was accurate and effective. We’ve been able to save hours of work with Tableau Prep, completely reinventing the way we look at our data, and dramatically shortening the time between data collection and actionable insights.
