Anyone else used Christian & Timbers for exec hiring?

Trying to get a sense of real founder and operator experiences here. Christian & Timbers came up in conversation as a search partner for filling senior roles, and I’m wondering how it plays out in practice.
Specifically curious about a few things:
How was the overall process? Did it feel structured or more hands-on?
Did they help clarify the role and expectations before starting outreach, or were you expected to come in with a pretty tight spec?
How were the candidate slates in terms of quality and stage fit?
Did it feel worth the investment compared to doing the search internally or working with traditional recruiters?
Any honest feedback from people who’ve worked with them for VP or C-level roles would be super helpful. Especially if you’ve been through both an internal-led search and a retained approach and can compare the two.
