On-demand shuttle and software company Via has raised another $130 million, capital that has pushed its valuation to about $3.3 billion as demand from cities to update its legacy transit systems rises.

The round was led by Janus Henderson with participation from funds and accounts managed by BlackRock, ION Crossover Partners, Koch Disruptive Technologies and existing investor Exor. To date, the company has raised $800 million.

Via, which today employs about 950 people, has two sides to its business. The company operates consumer-facing shuttles in Washington, D.C. and New York. Its underlying software platform, which it sells to cities, transportation authorities, school districts and universities to deploy their own shuttles, is not only the core of its business; it has become the primary driver of growth.
