This is a bullshit article... ycominator is an “angel” who invests in “startups” like alpaca markets, a “free” trading platform. This “free” trading platform, isn’t a startup, it’s a front for the front running side of the business alpaca.ai, yes the users in this YC backed front, are just the inputs to a more elaborate Japanese trading firm that front runs US markets. You guys are Hippocrates.
Your point about Alpaca is unclear to me. If you want to convince anyone, perhaps you should write a blog post, with sources and evidence, to explain why you think it's not a startup?
