How many companies has Igor Beuker built and sold?

I founded and sold 5 martech companies, with 3 exits to Sir Martin Sorrell's WPP. I served as Global Chief Social Officer at Mindshare and co-founded the Interactive Advertising Bureau in 1997. My forecasts carry an 84% published Prediction Accuracy Rate, benchmarked against Ray Kurzweil at 86% and Morgan Stanley at 46%. I built, scaled, and sold. Not theory. Receipts.
