^^ - you're selling AR as well? Last presentation was showing that to be a profit machine? Would love to learn about the reasoning behind that decision!
"Why sell AR?" is pretty straightforward: I'm CEO of Starfighter. I signed up for 5~10 years of my life building stock exchanges and getting devs better jobs, and that's more than enough work. It does not need to be interrupted by e.g. dealing with the Lithuanian hacker ring which found a novel way to route calls to Caribbean phone sex numbers. (A great story for another day.)
Focusing on one thing is best. I recently sold my SaaS for the same reason — I wanted to eliminate needing to worry about it while working on growing my other (more profitable) business.
(Lastly, as things that probably make Patrick excited to get out of bed and work, I'm assuming Starfighter > AR.)
