Trillium Solutions

What Trillium Solutions does

Trillium Solutions, Inc. (operating as Trillium Transit) is a Portland, Oregon-based transit technology company founded in 2008 that builds software tools and provides consulting services centered on the General Transit Feed Specification (GTFS), the open data standard used worldwide for public transportation trip planning. The company targets transit agencies, state Departments of Transportation, and regional planning organizations, claiming a customer base of more than 350 agencies globally. Its core product is GTFS Manager, described as the world's most popular web-based editor for creating, maintaining, and publishing GTFS data; the broader product suite includes GTFS-Realtime (live vehicle positions and service alerts), Interactive Maps, Transit Alerts, and rider-facing Transit Websites, all built on the GTFS open-data standard.

The company's technology stack is purpose-built around open transit data standards rather than proprietary algorithms. Trillium contributed to the open-source ecosystem (OpenTripPlanner, TransitDataFeeder) and played a leading role in the development of the GTFS-Flex extension for demand-responsive transit services, which was officially adopted into the GTFS specification in May 2024. The business operates on a combination of SaaS subscriptions for its hosted data management tools, professional services consulting (strategic planning and technology integration), and project-based transit website design work. Pricing is quote-based rather than publicly disclosed, and go-to-market is sales-led through direct engagement with public-sector transit decision-makers.

Since April 2022, Trillium has operated as a wholly-owned subsidiary of Optibus, serving as Optibus's Global Center for Open Transit Data. Within Optibus, Trillium's GTFS and passenger information expertise complements Optibus's cloud-based planning, scheduling, rostering, and operations platform, and Trillium's products are distributed through Optibus's global enterprise sales organization. Prior to acquisition, Trillium was founder-owned (Aaron Antrim) with no disclosed venture or private equity investment.

Direct peers

• Swiftly: Swiftly provides a transit data platform focused on real-time GTFS-Realtime, passenger information, and operations analytics for transit agencies. It is the closest direct peer to Trillium in GTFS-centric passenger information tooling, competing head-to-head on agency contracts.
• Remix (Via Transportation): Remix (acquired by Via) is a transit planning platform used by 1,000+ agencies to design routes, run scenario analysis, and publish schedules. It overlaps with Trillium's strategic-planning consulting and integrates with GTFS data, addressing similar transit agency buyer personas.
• Bytemark: Bytemark builds mobile ticketing and rider-facing transit apps that consume GTFS data from agencies. It overlaps with Trillium's Transit Websites and rider information focus and targets the same public transit buyer.
• Avail Technologies: Avail Technologies is a smaller direct peer providing GTFS, real-time, scheduling, and CAD/AVL software to mid-sized U.S. transit agencies. It competes with Trillium on a transaction-by-transaction basis for similar agency contracts.

Broad incumbents

• Optibus: Optibus is the parent company of Trillium since April 2022 and the broader cloud-based transit planning, scheduling, rostering, and operations platform. It is the natural adjacent incumbent with overlapping agency relationships and complementary (now integrated) functionality.
• TransLoc (Modaxo): TransLoc, part of Modaxo (formerly Trapeze), offers microtransit, fixed-route, and rider information tools to transit agencies. It competes in on-demand transit and passenger information, overlapping with Trillium's Transit Alerts, Interactive Maps, and GTFS-Realtime offerings.
• Cubic Transportation Systems: Cubic is a large incumbent selling fare collection, real-time passenger information, and transit analytics to major North American and global transit agencies. It competes for the same RFPs as Trillium at the large-agency tier, especially on real-time and rider information systems.
• INIT (Innovation in Transportation): INIT provides CAD/AVL, real-time passenger information, scheduling, and fare collection software for transit agencies worldwide. It is a broad incumbent with overlapping IT-software offerings against large and mid-sized transit authorities.
• GMV Innovating Solutions: GMV provides public transit technology including CAD/AVL, passenger information, and fleet management to agencies globally. It is an adjacent incumbent competing in the same rider information and real-time data space as Trillium, particularly on international deals.

Emerging players

• RouteMatch Software (MTS): RouteMatch focuses on paratransit, NEMT, and demand-response scheduling software, intersecting with Trillium's GTFS-flex work. It is a relevant emerging peer given the demand-responsive transit segment that GTFS-flex opens.
