Biography
Michael Rubens Bloomberg was born February 14, 1942 in Medford, Massachusetts. He earned an engineering degree from Johns Hopkins and an MBA from Harvard Business School. He joined Salomon Brothers, became a partner, and was fired in 1981 when Salomon merged with Phibro. With his severance of $10M, he founded Bloomberg LP. His first client was Merrill Lynch, which ordered 22 terminals in 1982. The Bloomberg Terminal, providing real-time financial data, analytics, and trading tools, became the indispensable tool of global finance — eventually generating $12B+ in annual recurring revenue.
Bloomberg served three terms as Mayor of New York City (2002–2013), winning the first term just months after 9/11. He governed as an independent, applying data-driven management principles to city government. After leaving city hall, he returned full-time to Bloomberg LP and expanded his philanthropic activities through Bloomberg Philanthropies, which has committed $14B+ to public health, climate change, gun safety, arts, and education.
Core Philosophy
Data democratizes power. Bloomberg's fundamental insight was that financial data was not a commodity — it was a moat. Whoever could provide the most accurate, fastest, most comprehensive financial information would capture the decision-making workflows of the most powerful financial institutions in the world. The Bloomberg Terminal at $25,000/year per seat seemed expensive; against the decisions it enabled, it was nearly free.
In God we trust; everyone else must bring data. Bloomberg applied quantitative rigor to everything: city management, philanthropy, policy advocacy. He funded data collection and analysis on gun violence outcomes, tobacco cessation rates, and traffic fatalities because he believed that good policy follows good measurement.

Lessons for the CFO Suite
Bloomberg's moat was not data — it was the workflow. Analysts who used Bloomberg for one task used it for all tasks. Workflow lock-in is the deepest moat in B2B.
The Terminal subscription model generates predictable, recurring, high-margin revenue. Bloomberg LP has never had an unprofitable year. Structure matters more than volume.
Bloomberg applied to philanthropy the same discipline as to business: measure outcomes, not inputs. Fund what works; defund what doesn't. Evidence-based giving.
