The money continues to pour in to the ground transportation sector - Flywheel is the latest with a $12 million Series C investment.
The taxi-hailing service is certainly used to having big money backing, having already secured close to $23 million since its launch in 2009.
The company claims four in every five taxis in San Francisco alone are partners with Flywheel to get customers via the Android or iPhone appliction.
The latest funding round comes via TCW/Craton, Rockport Capital and Shasta Ventures.
But more importantly, perhaps, is a new management team in the shape of ex-Webaroo and Junglee founder Rakesh Mathur.
He will be joined by Oneal Bhambani as the company's new CFO ho is essentially on secondment from TCW/Craton.
Coming the same week as Uber appeared to have scored a remarkable own goal when one of its executives suggested implementing spy-like activities to discredit naysaying journalists, Mathur has quickly targeted Flywheel's rival.
"The speed, safety and reliability of the taxi community combined with Flywheel’s ability to provide rides quickly has created a compelling alternative to Uber in San Francisco.
"We look forward to sharing this offering with taxi fleets across the nation while promoting an equal opportunity culture that rewards the honest, hard working drivers that Uber has vilified."
