I'm amazed at the number of startups about startups.
No but this is such a pattern in human history. Don't fight war, sell the weapons. Don't mine bitcoin, sell the cards. Don't start a startup, start a meta-startup (startup about startups). Easy $$$! Basically be the parasitic side-liner supplying to the often-fruitless follies of mankind.
Take a look at GPU company stock prices over the past 2-3 years for me will ye' ;)
It should be similarly unsurprising that companies like Apple, IBM, Cisco, Oracle, Microsoft, Stripe, Salesforce, Google, SAP, Amazon, etc. could also be described as "selling stuff to other people selling stuff to them."
