Micro-Transit Provider Circuit Closes on $17 Million

Circuit, a provider of electric, on-demand shuttle services, has raised $17 million in a Series B funding round led by MKB, with participation from Tribeca Venture Partners, Impact Engine, and others.

Circuit offers short-trip micro-transit services in more than 40 cities across the United States, utilizing a fleet of 100% electric vehicles. The company partners with municipalities, real estate developers, and advertisers to reduce congestion and transportation-related emissions while improving urban mobility.

Since its $11 million Series A raise in September 2022, Circuit has transported over 1.9 million passengers using electric vehicles. The company’s technology platform allows users to request rides through the Circuit app, integrating with public transit networks and urban infrastructure. In addition to its ride services, Circuit generates revenue through advertising partnerships, offering brands opportunities for in-vehicle and vehicle-wrapped advertisements.

In 2024, Circuit expanded its services to new markets such as Orlando, Avalon, Boca Raton, and Long Beach, while strengthening existing operations in San Diego, New York, West Palm Beach, Fort Lauderdale, and Huntington Beach. Founded in 2011 by CEO Alex Esposito and James Mirras, Circuit is headquartered in West Palm Beach, Florida.

“This Series B round marks an important step forward as we execute on our vision to electrify downtown transit systems,” said Mr. Esposito. “We’re delivering the right solutions at the right time, as cities look for ways to efficiently address congestion and emissions while improving access and mobility. This capital enables us to expand our partnerships, enhance our technology, and continue scaling sustainable, cost-effective transit solutions.”

“With a proven track record in scaling sustainable transit solutions, Circuit stands out as a leader in cost-efficient and rider-focused urban mobility,” said Antonio Occhionero, a managing partner at MKB. “We are proud to support Circuit as it continues to lead the way in redefining short-range electric mobility for cities, businesses, and commuters alike.”

Montreal-headquartered MKB specializes in growth equity investments in energy, mobility, the built environment (buildings, infrastructure, power grids, and public transit systems), and industrial sectors.
