Two years after purchasing Chariot from a San Francisco commuter ride-sharing startup, Ford Smart Mobility announced it is moving out of the shuttle service business and will cease operations in both the U.S. and U.K.

“In today’s mobility landscape, the wants and needs of customers and cities are changing rapidly,” said Dan Grossman, Chariot CEO in a blog post announcing the decision. “We apologize for the inconvenience this may cause Chariot’s riders and our enterprise customers. We are committed to ensuring our customers are aware of the decision and have time to make alternative transportation arrangements.

“We are truly grateful to our commuters, enterprise customers, and partners for your support over the past five years. Chariot was built on a commitment to help reduce congestion, ease the commute, and improve quality of life in cities, and since our start, we have provided our customers with more than three million rides,” continued Grossman. “In addition, we helped Ford build their mobility business, and their experience with Chariot continues to inform their mobility efforts and design decisions for the future.”

According to the blog post, Chariot said it was making a good faith effort to refund all remaining commuter credit balances after commuter service ends in the U.S. and UK; that it will work closely with its enterprise customers to develop a transition plan “that works best for their service and riders;” and that while the vast majority of charter trips booked are prior to Chariot’s closure date, it will work with those customers who trips scheduled after the closure date to identify and recommend alternate transportation.
