"One asked me straight out for $30 million. I told them I couldn't help them any further," he said.
Another had jumped into the Uber with a complete design of the investment opportunity, ready to show Erskine.
One pitch that stood out to Erskine was "a different take on My Food Bag", but he wouldn't be drawn on more details.
He had promised a follow up communication with two or three of the investors, and time would tell whether he pursued opportunities with them further, he said.
The unique setting for an investment pitch had got Erskine thinking about how investment pitches are typically carried out.
"It's a much more neutral space [in the car], typically this would happen in an office, but this is a more neutral, private space."
Demand was high for the Uber Pitch vehicles, with many people sharing on social media that they'd missed out on the opportunity.
The other investors that were participating in the process included social entrepreneur Derek Handley, founder of Orion Health Ian McCrae and entrepreneur and investor Roanne Parker.
