Souling is a waitlist-stage mobile app that generates a simulated phone call with the user's seven-year-old self, based on a short voice note or text describing how they feel. The product is positioned as a tool for nervous-system calming and daily emotional-regulation habits, with over 7,000 people reportedly on its waitlist. It was co-founded by CEO Leia Anapaula and CTO Pritvik Sinhadc.
