Haven't dug into them properly yet, but a quick skim of their site shows they've got some decent logos. That's usually a smoke test, not a guarantee.
What stands out to me is the "services as long as your arm" list. Unless they're white-labelling specialist partners under the hood, running SEO, PPC, CRO, web dev, and whatever else at a genuinely high level is near impossible. Seen too many agencies spread themselves thin and deliver average work across the board.
If you're evaluating them, I'd ask point-blank how they staff each service line and what their core focus actually is.
