met the co-founder Howie at a dinner in San Fran back in 2012 - I think the app was called Grid back then? Very passionate and driven, I remember him leaving the event early to work on the app.
I also remember my typical cynicism (held to myself of course) when he described the idea (what's this, Excel for ipads??!).. But now with a $1.1B valuation, wow - so well done to him and his team!
