About Millie Marconi

I'm a founder building tech solutions with the support of venture capital. My background isn't technical, but I've found that vision and determination can take you far.I'm passionate about AI, entrepreneurship, and the startup journey. Building a company has been a continuous learning process - from working with developers to making product decisions and adapting to market feedback.Networking and community have been invaluable throughout this journey. The connections and support from fellow entrepreneurs have made all the difference.Currently navigating the messy middle of a startup pivot - that challenging space between what was and what will be. It's chaotic, uncertain, and exactly where innovation happens. Stay tuned as we navigate this transition - we're excited to share our new direction soon. The only constant is change, and at Yesterday, we're embracing it fully.
