I wonder why "growth hacking" is so in vogue. It might be that more people know how to build products well, so getting distribution is more of an issue. It might be that more companies have taken a rigorous approach to things, shining as examples for the others. It might be that the avenues for growth are more democratized than ever, so instead of having a good rolodex for PR or BD, anyone can hack it.
Either way, it is a good thing and I look forward to reading some interesting stuff on this blog. I've found the most interesting stories are told privately, but hopefully Danielle can divulge more about Twilio & Referly internals because she left the former and runs the latter.
