Additional data points: Jeff Bezos over 30 when he started Amazon Marc Benioff 34 when he started Salesforce.com Peter Thiel was 32 when he took over Paypal (his first startup) Adobe founders were over 40 Cisco founder was over 30 Intel founders were close to 40 when they started the company All are huge companies worth tens if not hundreds of billions of dollars. Even Apple first iteration was 90 days from bankruptcy when Steve Jobs (aged 42) took over. At this point, his startup NEXT was not very successful. You seem to think $1B is some gigantic amount in the grand scheme of things. If you step beside tech, there are hundreds of examples. Take the example of Chobani yogurt. Started by a 33-year-old Turkish immigrant in 2005, the founder is a billionaire today. Companies started by founders older than 30 is the norm and will become so in tech too. Only in tech this foolish idea keeps persisting that only people under 30 do big things.
