Curb management platforms are a class of urban tech that use data, sensors, and digital mapping tools to coordinate how curbs are used in cities. The stated goal is to balance competing demands from road users like parking, deliveries, rideshare, bikes, pedestrians, and others, but in real time. The wave of companies that represented this field during its boom from 2018-2020 have mostly been shut down, absorbed, or abandoned: Coord was bought by Sidewalk Labs just as Alphabet was dissolving it into Google, and the open standards meant to keep curb data portable have sat untouched for years. City-run programs and the Curb Data Specification continue.
