sustainers
Those who maintain
Sustainers are people or things that keep something going, providing ongoing support or nourishment.
The term often appears in fundraising contexts, where a sustainer is a donor who gives regular, recurring contributions rather than one-time gifts: Monthly sustainers provide reliable funding for the nonprofit.
In rocketry, a sustainer engine maintains thrust after booster separation.
