Aline Pilates is a single Brooklyn studio that its founder, Carey Macaleer, has owned and run since opening it in 2016 — no investors, no franchise, no second location. In a boutique-fitness category increasingly rolled up by private equity, it answers to its owner and her Carroll Gardens neighborhood rather than to a fund's growth timeline. As a small, single-location studio, it has generated little public record on labor or environmental practices to check; what stands out here is the independent ownership, not a proven conduct record.
