The pattern I've seen repeated everywhere: A genuinely knowledgeable expert sells their expertise via online content, books, and seminars. This attracts the clients. The expert will attend a few key client meetings. But then, unbeknownst to the client, they disappear and leave the work to juniors.
This is so ubiquitous that, earlier this year, I decided to change my career aspirations. I'd long wanted to be an agency leader, but the pattern above was repeated at every successful agency I came across, and it's not something I can stomach any longer.
So, I decided to put myself out there as the expert. I write a newsletter. I published a book. I'm pursuing speaking engagements. Just like the other consultants do.
However, I don't pass my clients onto anyone else. They're hiring me. They were sold on my expertise, so my expertise is what they're going to get.
When a project grows too big for one person to handle, or when there are aspects of the work that don't justify my high hourly rate, I transparently inform my clients of my intention of bringing on freelancers for those aspects. It's all done out in the open.
And while I do charge a markup on the work my subcontractors do on my behalf, it works out to far less than my hourly rate, and my clients are fully aware of the markup being charged and what value I'm providing in return (i.e.: supervision).
All of which is to say: I think consultants can provide incredible value. (I know, I know... a consultant who believes on consulting. Shocking!) But you do have to be careful, and oddly enough, the bigger and more reputable the consulting firm, the less I would trust them. The business rewards bad players.
