March 17 (Reuters) - HR and payment software startup Rippling said on Friday it has raised $500 million in a new funding round initially intended to help customers make payroll in the immediate aftermath of Silicon Valley Bank's collapse. The round, led by technology investor Greenoaks Capital, gave Rippling the same valuation of $11.25 billion it had clinched after its previous capital raise last year, the company said. Unclear if customers' funds would be recovered by Monday, Conrad started to seek more capital from investors, whose funds were also partly stuck with SVB. Growth equity firm Greenoaks was one of Rippling's investors that have funds available to wire on Monday. Rippling offers services to businesses to manage their human resource and information technology operations such as employees' onboarding and payroll management.
