Bill Gates is an American entrepreneur and philanthropist best known as the cofounder of Microsoft, the software company he built into a dominant global technology platform. Born in 1955, he led Microsoft’s product strategy and business direction for decades, helping bring personal computing to scale. This profile outlines his career milestones, estimated net worth, and long‑term philanthropic work through the Bill & Melinda Gates Foundation. It also clarifies his current involvement with Microsoft and separate ventures, focusing on verifiable facts and publicly reported information rather than speculation or rumor.
Early life and education
Gates was born on October 28, 1955, in Seattle, Washington. He attended public school in Seattle and enrolled at Lakeside School, a private preparatory school where he discovered access to a Teletype terminal and early computer programming. He entered Harvard College in 1973 but left in 1975 to cofound Microsoft with childhood friend Paul Allen. He has since received honorary degrees from institutions recognizing his impact on technology and global health, though he never completed a bachelor’s degree.
Founding and leading Microsoft
In 1975, Gates and Paul Allen cofounded Microsoft to develop software for the emerging personal computer industry. Through the 1980s and 1990s, Microsoft licensed MS-DOS and later released Windows, which became the leading operating system for PCs worldwide. Gates served as chairman and chief software architect, shaping product roadmaps and business strategy. He transitioned out of day‑to‑day leadership in 2008 to focus on philanthropy, though he remained involved in technical and strategic reviews.
Product and strategy highlights
Key moments in Microsoft’s history under Gates include the partnership with IBM to license MS‑DOS, the launch of Windows, and the expansion into enterprise software and office productivity. These products helped establish Microsoft as a core part of business and home computing and created the scale that underpinned his subsequent net worth.
Net worth and sources of wealth
Gates’s net worth derives primarily from his residual stake in Microsoft, substantial holdings of Microsoft stock, and investments in various companies and funds. He has also held stakes in firms such as Berkshire Hathaway and TerraPower. His wealth is heavily tied to the performance of Microsoft shares and market conditions, and it fluctuates over time.

Philanthropy and global health
Through the Bill & Melinda Gates Foundation, which he established with his then‑wife Melinda French Gates, Gates has directed resources toward global health, vaccination, agriculture, and education initiatives in low‑income countries. The foundation has funded programs to reduce diseases such as malaria and polio and supported pandemic preparedness efforts. These activities are documented in foundation reports and independent evaluations, though their scope and impact are subject to ongoing assessment.
Transition away from Microsoft
Gates stepped back from Microsoft’s executive leadership in 2008 and left the board of Microsoft in March 2020 to focus on philanthropy and other projects. He has since maintained an advisory role on occasion and discussed technical topics in interviews, but he is not involved in Microsoft’s day‑to‑day operations. Former employees and public statements clarify that his current work centers on his foundation and select investments.
Current projects and public presence
Today, Gates remains active in global health, climate innovation, and education through his foundation and personal investments. He has written and commented on public health, energy, and technology policy in interviews, books, and reports. He is divorced from Melinda French Gates and has established separate foundations, continuing his focus on large‑scale philanthropic efforts while remaining a prominent public figure.
Addressing misinformation

This profile emphasizes verifiable facts, such as his role at Microsoft, his net worth sources, and documented foundation work, and avoids speculative or unverified assertions.
