Opencoffee is not your ordinary meetup. There are far too many of them.
1. There is a very active mailing list - please do join, I challenge you to ask a question which doesn't receive an answer
2. There is a meetup every week, on Thursdays. From July 28th 2016 we are trying out a private members club called Eight Club next to bank tube station. Unlike other meetups, there are NO agendas, and NO presentations. It is pure networking. We simply provide the place. If you do attend, do try to buy yourself a coffee or two, helps the hosts run their business. They also have really nice pool tables and comfy sofas.
4. If you need to get hold of me please email me on email@example.com If you have any specific questions about your startup, raising funding, intro's to angels etc, please post to the list, you will get far more replies.
