Los Angeles, CA, April 11, 2023 – Vance Street Capital LLC (“Vance Street”), a Los Angeles-based private equity firm, today announced the official launch of Synapse ITS (, a comprehensive transportation technology platform focused on increasing roadway safety, efficiency, and accessibility through innovative infrastructure.

Comprising four established, industry-leading brands–Polara Enterprises, Carmanah Technologies, Eberle Design Inc.
