- Don't worry about NDAs with VCs. At least on this side of the pond, no VC is going to sign them. Don't leave your full deck behind in digital form. Leave them a summary deck on paper if you absolutely must. (just assume the deck will get passed outside the firm).
- Do make sure the VC doesn't have a conflicting investment - if so, assume everything you talk about will be going into the ears of your competitors.
- Avoid spotters/associates. Get referred in to a partner by another entrepreneur they've worked with before (work your linkedin or xing). Don't take a 1st meeting with an associate (feel free to chat with them on the phone briefly). If a firm wants to see you, then they can find a partner to talk to you. Associates can only say 'no' and generally have limited deal experience and just may not understand your market (of course there are exceptional individuals and firms where this doesn't apply).
- Timing is everything. When you're ready to go out - have a list of VCs you want to speak with and try to get all your meetings lined up for the same two to three weeks. VCs all talk to each other. Once they hear another firm passed on your deal, it's harder to get the next one to bite. Make it a parallel competition. Don't overexpose your company.
- Do research on the firm and the partner that you're pitching. http://www.thefunded.com is free for founders. Get an account and use it for research. (I'm not affiliated with thefunded, just a fan).
