Shuang Li shares three key learnings from founding EstateBaron, a startup founded in 2015 that has raised $2 million from 1400+ investors for 3 projects. The first learning is to choose the right business partner to build the startup journey with. The second is to truly understand and suffer from the problem being solved. The third learning is to embrace mistakes made along the way and view them as opportunities to build a 10x better solution within the startup's capabilities.
