7th Street Burger
Fast casual burger chain · 36+ locations · NYC, NJ, CT, MA, PA, DC, MD
7th Street Burger is still run by the founders who opened its East Village smashburger stand in 2021. But private-equity fuel from Left Lane Capital and Stripes now races it toward 100 corporate-owned locations in two years.
The Big Picture
7th Street Burger is still founder-run: Kevin Rezvani and Paras Jain opened its East Village stand in 2021 and operate it today. Posted pay runs $13.70–$17.55 an hour, putting New York roles at the $17 minimum with no cushion. The growth money is not the founders': Left Lane Capital and Stripes back a plan to reach 100 corporate-owned locations.
