Obviously, this makes it less scalable, but I do spend my nights writing software for 10x to automate the things we find ourselves doing more than once. (I spend my days working on deals... still working out the balance; see PG's essay about maker/manager schedules.) And one of the things that's always at the back of my mind is how to maintain the high-touch, personal approach as we scale.
And I regret nothing.
Magic? Nope. I have such system in place.
Unless you have a stable of subs (which I recommend -- to the adventurous, only!), how do you manage the dialogue volume?
In terms of dialogue, I searched for key terms in replies, and only replied to those that fit. I did miss on good leads, but the follow up email got me back on their mind and they would always reply.
Though I wish I could do it with someone else (a co-founder, if you will). This sort of thing could make a lot of money in the right markets. They do exist already, but most are antiquated. The advantage that I have is that I do my own email campaigns. So the emails that get sent out are actually A/B tested for performance.
I do plan to offer the actual emails that I sent to get clients for around $20 soon. Its an easy way for freelancers to get clients without much hassles. If you are interested, then shoot me an email.
EDIT: Finally one, how are you crawling? Aggregating lists or web crawling? Tips?
I don't use it anymore, because I have a long term contract.
Except for specific sites like elance, this isn't something I've seen much of.
