I'm terrified of doing this.
I'm not an angel investor but I'm a good salesman. What we are really talking about here is selling yourself. I'd be glad to offer advice on that. Feel free to contact me.
Eg. if you're particularly experienced with gaming, don't bother trying to sell yourself to a SaaS startup, there will probably be someone there specialized in that.
Of course I'm speaking here as a founder who has never raised any funding, so everything I say on the topic is deserving of multiple grains of salt.
