Three days into his tenure as Silicon Valley Bank 's government-appointed CEO, Tim Mayopoulos has a message for his high-powered venture capital and startup clients: Bring your money back. "There is no safer place in the U.S. banking system to put your deposits," Mayopoulos said on the call, which CNBC attended and was first to report. SVB's former CEO and CFO are no longer employed by the bank, Mayopoulos said on the call. Customer feedback will be critical in determining the future of the bank, Mayopoulos said on the call. "There are other places that do venture debt, but Silicon Valley Bank was the 1,000-pound gorilla in the room," said Ami Kassar, CEO of the business lending consultant Multifunding.
