Citymappers founder, Azmat Yusuf, gave a talk at the Hacker News London meetup earlier this year and it was categorically one of our most popular talks in a long time. Unfortunately Azmat (very politely) requested that we not record his talk for our vimeo page (vimeo.com/hnlondon) which is a shame because it was incredibly insightful.

If you get the opportunity to attend a talk by Azmat or any of the team, take it. They are an exceptionally clever and humble bunch and I'm thoroughly enjoying being a witness to their growth and success.
