Bro it's a biotech startup, what exactly did you expect? Everything that startups do is a mixture of hype and legitimacy that's encapsulated by tough challenges that will require solving. They have definitely shared internal science & progress with their investors, but also, the original paper and research that led to the creation of the company is available for you to read right off their website.I'm not sure I understand what you're saying here, explain it differently for my thick head to understand: "Also, because of the leak of their series a pitch deck we found out they were already raising their next round while officially they had just announced they had secured their seed capital."
What you say is hopeful and encouraging. Now in terms of investors, do they have publicly traded stock? If they can crack the code to regrow perfect cycling hair, anyone who invests in them will make a fortune!
Yes, the fact they hired a bunch of new people must mean something's up. This is the most telling thing you mention. Probably a number of aspects still need refining. Geez, imagine all this work needed just to reproduce hair!? If it's this difficult to do it makes a person wonder if G-d didn't want this, thus making it so difficult to engineer?
I wish they could sort of tell me that they are close at least, even if they don't want to give the details. Truth is if we're not at human trials, how close can we really be?
However the fact all this money is being allocated to them by investors must mean they (Stemson) either has a great publicity team or they share their information only with privileged people and groups who have funds to make a difference. Mind you, this is all speculation.
Lastly, Stemson is hiring people because they closed a round of funding and are in the process of scaling the business.
