Millie Marconi Left $100K on the Table Because a LinkedIn Post Changed Everything

Hey Crew!Millie Marconi has been building for 9 years. In that whole time she's had exactly one real job, and it only lasted a couple of months. She's the kind of founder who doesn't wait for permission, which is exactly why this episode hit different.We get into the LinkedIn post that nearly broke her (and ended up building her next company), how she walked away from $100K in revenue because the vision was bigger, and the AI product she built back in 2019 that she dropped, the one that basically became Heidi Health.Millie's current company is TestFeed, a synthetic audience platform for B2B market research. The industry is a $140B one, 70% of it is going synthetic by 2028, and she's already got 3000 people on the waitlist. She just pulled the B2C product and is going all in on enterprise. Raise is coming.But beyond the startup stuff, we talk about building as a neurodivergent person, what it means to be a dark horse, and the Italian grandfather who crossed the world with nothing and became a horse trainer. That part will get you.We cover:- The accidental origin story of TestFeed (a LinkedIn post gone very wrong)- Killing a $100K revenue product to go after something bigger- What synthetic audiences actually are and why B2B is the play- The AI note taker she built in 2019 (before the space blew up)- Her grandfather and the "build with what you've got" mentality#fayltales #founderlife #startuppodcast #buildinginpublic #startupstory Follow us on all platforms!Instagram ~ @fayltalesTiktok ~ @fayltales LinkedIn ~ @fayltales
