Oscar Casanova is a finance leader focused on building FP&A and strategy functions that help companies scale with speed, clarity, and discipline. He works at the intersection of finance, operations, and go-to-market execution, partnering with leadership teams to translate growth ambition into durable business outcomes. Oscar began his career at Goldman Sachs, advising on more than $30 billion in transactions across acquisition financing, leveraged buyouts, and debt capital markets, where he developed a first principles approach to strategy and capital allocation. He later moved into operating roles to build businesses from the inside, holding finance leadership positions across venture-backed companies from seed stage through Series E, as well as public companies including Zillow Group and Shopify. He has repeatedly stepped into first-in or transformation roles, helping scale a Series C company from $35 million to $70 million in ARR and leading the financial strategy for an inaugural software product within a publicly traded company, growing it by over 700% year-over-year. Oscar currently serves as CFO of a stealth startup, where he is designing the financial and strategic infrastructure for its next phase of growth. His work centers on evolving FP&A from a reporting function into a true operating discipline that removes friction and drives better decisions at scale.
