After building two multi-hundred-million-dollar platforms, why not simply retire, and what is the core mission behind Lossdog?

Retirement sounds like misery to me. I have no conventional hobbies; building companies and trading markets is what gives me purpose. With thinkorswim, we revolutionized financial software. With tastytrade, we revolutionized financial media. With Lossdog, we are building an ecosystem centered on mathematical optimization for careers and investment portfolios. Most people have no idea what their actual market value is in the workforce. We are using quantitative modeling to help individuals understand their true market compensation, negotiate effectively, and manage their money intelligently.
