Valerie Kalderon COO, Opening Bell Ventures LLC

Valerie Kalderon

COO & Co-Founder

Valerie learned a lot about planning, people and process from an early age. Being one of seven children in her “Brady Bunch” family meant finding efficient and thoughtful ways to get her way. She carried that experience over to her career of 25+ years on Wall Street where she was a senior leader of global teams in technology, program management, product management, operations and client services. She is known to her teams as “the Fixer,” give her a challenge and she will get the right people, process and technology to get it done ahead of time and under budget. Key to her success is her ruthless determination to get to the finish line while building strong partnerships and trust along the way.


Valerie spent the majority of her career at JPMorgan running enterprise programs for the Investment Bank. Her extensive experience in data management, technology and operations led her to Head of Customer Care at AngelSense, an Israeli startup. At AngelSense, she gained the invaluable experience of  bootstrapping and running an entirely remote Global Customer Care organization.


When not managing Opening Bell’s investments and day-to-day operations, Valerie can be found traveling the country competing on her stable of horses.
