Is Crimson Education Legit?

Has anyone had experience with recruitment at Crimson Education? They appear to be expanding rapidly. However, I found it a bit odd when I received a message on LinkedIn from their “COO” inquiring about my interest in a position. Is it strange for the COO of a “fast-growing edtech company” to be reaching out directly to candidates? They have numerous recruiters on LinkedIn as well. Maybe I’m overthinking it, but it feels a bit off to me. What are your thoughts or experiences?
