Why are yang and filo wealthier today than they were when they owned one hundred percent of the company?

Yang and Filo are wealthier today than when they owned 100% of their company because they likely capitalized on the increased value of their equity stake after raising funds or selling shares, which diluted their ownership but significantly increased the company's overall valuation. By bringing in outside investors, they could fuel growth and expansion, leading to higher revenues and profits. Additionally, their personal wealth may have grown through strategic investments and diversification of their assets beyond the original company.
