Just Salad
Dining · 110+ locations — Just Salad is B Corp-certified, with third-party-verified carbon labels on every menu item. It's still founder-run after 20 years, but now backed by $436M in institutional capital at a $1B valuation.
Sweetgreen
Dining · 301+ locations — Sweetgreen has been publicly traded since 2021, with Goldman Sachs and Point72 among its institutional investors. Unusually, the co-founders still control the company through a dual-class voting structure: Wall Street money, founder votes.
