Congrats again to Lotan Magal and AskIt! 🏆 AskIt won 1752vc’s Lightning Round IX. The startup predicts real-world consumer behavior by simulating how people think and decide. It combines behavioral science with predictive modeling to help brands test creative, model their real audience, and validate products before launch, so they know what will land before they spend. Lotan pitched live to our investor panel and stood out in a highly competitive lineup. We can’t wait to see what’s next for the AskIt team. Huge thanks to our judges Keith Yoder, Vinnie Shahzad, and Avag Simonyan, and to our Lightning Round IX partners Ramp, Stubbs Alderton & Markiles, and Innovent Capital.
