What do you think of

They say, they will get the maximum out of 28nm-Asic while price will stay cheap. A lot of blabla, but no concrete reason, why their asics will be so wonderfull. The CEO claims to be an ex-chip-designer from samsung, intel, qualcomm, nvidia, but searching his name I found just the coindesk-articles, a linkedlin-file and a medical scientist. Same results for his partner.
They say, they don't sell by now, but will soon. On some site they say, they are gathering funds, they have 1.5 Mio $, but want to have 3 Mio $ before they'll be able to start production.
Adress ist "Texas, USA". No phone number.
In my eyes it's highly suspicious.
