They tell you what you need to hear, not what you want to hear
I came to Metta as a very general coach who'd just left nineteen years in the music business and had no clear way of saying what I did. They pointed out the obvious thing I'd missed: I was competing with eighty thousand other general coaches when I could be the music veteran who retrained as one. Since then they've helped me define the business, find my voice, build a website I'm pleased with, and widen what I offer from coaching into advising founders.
For the first few weeks I dreaded the calls, because I knew I'd be challenged. That changed, and the challenge turned out to be the whole point of it.
They don't come in and do it all for you - there's plenty you have to keep doing yourself, but you're doing it with very good people around you, closer to a team of co-founders than an agency. If what you want is to be told you're brilliant, they're not for you. If you want honest advice, I'd recommend them wholeheartedly.
