Price any road, anywhere, any time -- the world leader in smartphone-based GPS tolling, HOV verification, road user charging, and dynamic road pricing without roadside infrastructure.
Carma Technology Corporation is the world leader in smartphone-based road pricing, providing GPS tolling, HOV verification, road user charging, and dynamic congestion pricing solutions. Founded in Ireland in 2007 by serial entrepreneur Sean O'Sullivan as part of his MapFlow GIS company, Carma has evolved from a ridesharing app startup into a proven tolling platform that processes over one million monthly transactions without any roadside infrastructure -- using only smartphone GPS and cloud computing. Carma's flagship GoCarma app functions like a toll tag but operates entirely through smartphone technology, automatically detecting when a vehicle enters a priced facility and processing transactions hands-free. The system is integrated with two high-volume toll transaction processing systems in the Dallas-Fort Worth region, where it operates across a 120-mile network of TEXpress managed lanes serving 78,000 daily commuters with HOV toll discounts. The platform has also been deployed by Louisiana DOTD for I-12 managed lanes in Baton Rouge, and in 2024 Carma launched a demonstration in New York City to prove smartphone-based congestion pricing as a fairer alternative to gantry-based systems. In January 2026, Carma and Texas partners completed the nation's largest road usage charge pilot, enrolling over 41,000 participants and capturing more than 64 million miles of real-world driving -- exceeding the combined scale of all prior US RUC pilots. The Texas A&M Transportation Institute independently confirmed the pilot's relevance for future statewide and multi-state RUC planning. Carma's hardware-free, cloud-based approach enables per-transaction costs as low as $0.18, a fraction of traditional toll infrastructure costs, making it particularly relevant for New Zealand's evolving RUC system.
Hands-free smartphone application that functions as a toll tag without requiring physical hardware or roadside infrastructure. Automatically activates when entering tolled facilities, processes transactions using GPS positioning, and displays charges in real time. Available on iOS and Android. Processes over 1 million monthly transactions in Dallas-Fort Worth alone.
Smartphone-based system for automatically verifying high-occupancy vehicle (HOV) compliance on managed lanes. Uses Bluetooth and smartphone sensors to detect vehicle occupancy without manual inspection. Deployed across 120 miles of DFW TEXpress lanes, reducing HOV violation leakage rates to below 2%.
Cloud-based tolling solution that replaces traditional toll tags, gantries, and on-board units with smartphone GPS. Integrates with existing toll transaction processing systems. Proven at scale with two major toll operators in Dallas-Fort Worth. Per-transaction costs significantly lower than infrastructure-based alternatives.
Smartphone-based mileage tracking and billing platform for distance-based road user charges. Successfully demonstrated at unprecedented scale in the Texas Miles Matter pilot (41,000+ participants, 64 million+ miles). Hardware-free design allows agencies to adjust rules, corridors, and pricing structures quickly.
Location-based road pricing solution that can price any road based on real-time traffic flow, air quality, or policy objectives -- not limited to managed lanes or congestion zones. Demonstrated in New York City for Manhattan congestion pricing. Supports discounts for low-income drivers and high-occupancy vehicles.
Founded by Sean O'Sullivan as a research and development division of MapFlow, an Irish GIS company. Initially focused on real-time ridesharing technology.
Released a ridesharing app on the iPhone, matching riders to drivers in real time. One of the earliest smartphone-based mobility applications.
Incorporated in Ireland as Avego Limited (March 2009). Directors include Sean O'Sullivan, Lawrence Mulligan, Joseph Cunningham, and Alan Moore. Associated with University College Cork.
Rebranded from Avego to Carma, pivoting focus from ridesharing toward smartphone-based tolling and HOV verification technology.
Lawrence Mulligan appointed CEO after O'Sullivan relocated to the US. O'Sullivan remained on the board and continued involvement through SOSV, his venture capital firm.
Deployed GoCarma smartphone app for HOV verification on Dallas-Fort Worth TEXpress managed lanes in partnership with the North Central Texas Council of Governments (NCTCOG).
Selected by Louisiana DOTD to operate smartphone-based tolling on I-12 managed lanes in East Baton Rouge, the 4th most congested city in the US.
DFW operations reached milestone of processing over 1 million monthly transactions across 120-mile managed lane network, with 78,000 active commuters.
Launched GoCarma smartphone app in New York to demonstrate fairer congestion pricing. Set up in less than 30 days with MTA support, showing real-time transaction processing across Manhattan bridges and tunnels.
Completed the nation's largest Road Usage Charge pilot with Texas DOT and NCTCOG -- 41,000+ participants, 64 million+ miles captured. Texas A&M Transportation Institute independently validated the results for statewide and multi-state RUC planning.

Chief Product Officer
Oversees product strategy for GoCarma's tolling, HOV, and RUC platforms.
Carma Technology has demonstrated the most scalable smartphone-based RUC solution in the United States. The company's January 2026 Texas RUC pilot was the largest ever conducted in the US, enrolling 41,000+ participants and capturing 64 million+ miles -- exceeding the combined scale of all prior US RUC pilots. The independent evaluation by Texas A&M Transportation Institute confirmed that per-user administrative costs decline sharply at higher enrollment levels, addressing a key sustainability challenge for statewide RUC programs. Carma's hardware-free, infrastructure-free approach is particularly relevant to New Zealand's RUC modernisation, as the Ministry of Transport seeks third-party providers who can offer cost-effective RUC payment platforms for light vehicles from 2027.
