How have you gone about messaging someone first? What're some important points you first discuss? How did you manage to persuade them even if you did not possess their wanted skills?
I'm not looking to join a team however I am building a team for my start-up Herbal Express. If I were in your shoes I would simply just express interest in the company. You can even go as far as detailing ways you could be considered an asset to them. You may not have the skills they are currently looking for but as companies grow they will always look for new talent. Not the most profound advice but from my experience, I have run into people who have expressed interest in my start-up but at my current state, I do not have use for them. As we grow the people that I have previously spoken to about my company will be highly considered when I can bring them in. Building relationships with like-minded entrepreneurs can never be a bad thing.
Get straight to the point. When I get messages, I want to know in the first sentence why you are contacting me and I don't like messages like "how are you doing?" etc. from people I don't know. When I contact people, I usually write something like - "David, I'm contacting you for....", just out of respect for their time and I have a pretty good response rate with this.
I think niceties have their place in time and space. I would never trust someone who was a 100% professional. We are humans after all not robots. How busy can someone be, it's not like we are playing being Barack are we! Even he is a nice guy and makes time for niceties so what's someone else's deal here I dont understand!
