Sadly the UK has a long history of sending its own tech industry abroad...

It begun with the invention of the computer as we know it... - Charles Babbage,"Father of the computer", British - Alan Turing, "Father of modern computer science", British

Then there was Margret Thatcher who decided the internet was a fad and wasn't worth investing in internet infrastructure in the country.

Where did the multi billion (if not trillion by now) industry end up? Silicon Valley and elsewhere....

Bravo UK... Bravo </sarcasm>

Success to you is for you to define. Don't fall into the trap of VC funding because its all you read on HN or Techcrunch. What you have built is your baby so don't let anyone else tell you what you should be doing. It sounds like you have so much meaning and purpose in the company you have. If (and it sounds like) you don't want the vc money, then that is the right decision for you.

Interested to hear what the HN community thinks about 1Password
