Replica, founded in 2017 and spun out of Alphabet, operates a SaaS platform for travel demand modeling. Its core product synthesizes hundreds of data sources - including mobile location data, vehicle telematics, census records, transit feeds, and ground-truth observations - to produce a synthetic, high-fidelity picture of how populations move through cities and regions at different times of day. The platform claims to be the world's first nationwide high-fidelity travel demand model and is delivered entirely as SaaS.
The technical domains the platform spans are broad: synthetic population generation, geospatial analytics, demographic segmentation, scenario analysis, and multimodal transportation modeling. Outputs are broken down by travel mode, trip purpose, demographics, and destination, and are used to evaluate trade-offs across transit equity, road safety, economic development, and infrastructure investment. Customers include hundreds of public agencies and private companies, among them Caltrans, Texas DOT, Illinois DOT, the MTA, and Waymo.
Replica's platform serves a range of clients across departments of transportation (DOTs), metropolitan planning organizations (MPOs), municipal governments, transit agencies, real estate developers, and private mobility companies. The underlying engineering work involves processing and integrating large volumes of heterogeneous data - location signals, telematics, administrative records - into consistent, queryable models of urban mobility.
