Machine learning

Agora Production · Co-Founder

ML consultancy: predictive algorithms, market forecasting, voice and pattern recognition, plus M&A and technology advisory

Sold

First company, founded in Montreal: machine learning consultancy a decade before it was fashionable
Shipped predictive algorithms, market forecasting, voice recognition, and pattern recognition for clients, alongside M&A and technology advisory
