Every published round Y Combinator took part in, and every parcel of existing shares it bought off another holder. Deals we hold but haven't published yet are not counted, and a place in one of its own programs is under Cohorts.
Everyone Y Combinator has named to a program in published coverage. A place in a program is not a raise: the cheque is the figure recorded with the place, which is the program's standard terms where we hold them, and a blank is one we don't.
