I've spent the last five years building two companies (Grovo, Inventure) that are truly and rapidly changing the world. Now I'm addicted. I live to create simple solutions to big problems.
Building stuff is hard so I always test manually before engineering/automating. And everything takes more work than expected, so I try not to waste energy on stuff that doesn't have the potential for major & systemic impact.
My motto is: "Empathize -> Hypothesize -> Test -> Scale"
I blog (often about my experiments/tests) here: https://medium.com/@ajr771
I tweet (often about nothing) here: https://twitter.com/ajr771
