This conference would be useful to a start-up for the people you meet (you will need an accountant sooner rather than later) as well as the things you learn. My suggestion if you go: use this event for schmoozing as much as you use it for knowledge.

There is a special landing page and discount code for readers of Hacker News: $50 for the whole day. Did I say lunch is included?

On December 11, 2014 (the same day) -- Thursday night -- I will be in the bar at the Hyatt Regency Hotel in the Embarcadero Center, with a credit card . . . uh . . . networking. CalCPA's International Tax Conference is on Friday, December 12, 2014; I'm the chairman this year.

If you want to meet, show up at the Hyatt Regency on Thursday night or email me at my HN username on Gmail and I will send you my mobile number. I will do my best to answer your hard startup-related international tax questions. :-)

I am heavily involved in the California Society of CPAs and its educational programs, even though I am not an accountant.
