Duolingo co-founder Luis von Ahn joins Guy on the Advice Line to answer questions from three early-stage founders. Plus, Luis shares insights on how data can help entrepreneurs understand what their customers really want. First, Steph in Chicago wonders how to manage expansion opportunities for her art-filled vending machines. Then Blair from Atlanta discusses his challenge of selecting which products to focus on with his tech accessories brand. And finally, Stephanie in Indiana considers the best way to fund more employees for her growing business designing living plant walls.  Thank you to the founders of Good Things Vending, Bair, and Naturspire for being a part of our show.
