What to ask any agency coach before you hire
A good agency coach should be able to tell you which bottleneck they solve, what stage of agency they work best with and what a session actually looks like. Ask whether they will look at your real numbers, whether you get one-on-one time and what happens if your problem is outside their specialty.
Ask for client stories you can verify. Tim Kilroy publishes founder testimonials at timkilroy.com, and you can read more in marketing agency coaching.
