Lambda appoints Leonard Speiser as Chief Operating Officer

Speiser brings more than a decade of experience founding and operating complex, capital-intensive, and mission-critical technology businesses.

Clover now processes over $300 billion in credit card transactions a year. Earlier in his career, Speiser held roles at Intuit, eBay, and Yahoo, and worked in technology corporate finance and M&A at Credit Suisse First Boston.

"Leonard joining Lambda is an amazing opportunity to work with a fellow founder who has built a company from the ground up," said Stephen Balaban, co-founder and CEO of Lambda. "Leonard is a keen and thoughtful operator who has built technology used by millions of people. It's an honor to welcome him to the team."

Speiser’s appointment comes as Lambda continues to expand its leadership in AI infrastructure, serving tens of thousands of customers. The company recently announced a $1.5B+ Series E fundraise to help enable Lambda’s development of superintelligence cloud infrastructure.

"Lambda's differentiated position as an AI pure-player, combined with their deep expertise and modular datacenter architecture, positions them to deliver the global-scale compute that has the potential to power humanity's AI future,” said Speiser. “I'm excited to help grow these critical operations."
