Ignatios's crew of volunteers

"From the onset of the crisis, Ignatios’s crew of volunteers has cooked 350 meals a day, but with demand mounting has increasingly come to rely on donations from the country’s pre-eminent food rescue organisation, Boroume." (The Guardian.)

Is "Ignatios’s crew of volunteers" a subject in the clause "...has increasingly come to rely on donations..." in the sentence above?
