Louis B. Mendelsohn stands as the visionary who revolutionized trading technology through artificial intelligence and intermarket analysis, transforming how independent traders navigate global financial markets. As founder of VantagePoint AI since 1979, Mendelsohn pioneered the world's first commercially available AI-powered trading software, creating breakthrough neural network technologies that predict market movements with up to 87.4% accuracy.
Louis B. Mendelsohn was born in 1948 in a public housing project in Providence, Rhode Island, where economic hardship shaped his determination to succeed. Despite growing up in challenging circumstances, his father encouraged him to pursue higher education as a pathway to greater opportunities.
His patented innovations in intermarket analysis and predictive indicators have empowered over 47,000 traders across 120+ countries, establishing him as the industry's most influential figure in technical analysis software development. From his groundbreaking 1983 release of the first strategy back-testing software to his continuous investment of over $10 million in research and development, Mendelsohn's four-decade journey represents the definitive fusion of artificial intelligence and financial market forecasting.
"That excitement of computers, software, financial markets, and the intersection of the three is what has kept me excited and inspired by VantagePoint."

1983: Industry Breakthrough
Released ProfitTaker Futures Trading Software, the world's first commercially available strategy back-testing software for personal computers. This groundbreaking program brought worldwide recognition and established the gold standard for trading software development.
Industry Transformation
ProfitTaker's strategy back-testing approach was adopted by others, leading to programs like TradeStation® (1991), transforming technical analysis into a multi-million dollar trading software industry.
Pioneering Intermarket Analysis and AI
In the mid-1980s, Mendelsohn recognized the structural changes occurring within global financial markets and the dynamic interconnections between related markets. He developed an entirely new approach to computerized technical analysis that analyzed global market relationships rather than individual markets in isolation.
1991: VantagePoint Software Launch Released the first commercially available artificial intelligence-based intermarket analysis software. The program uses neural network pattern recognition to find hidden relationships in global data and forecast future price action with exceptional predictive accuracy.
