M12 is the corporate venture-capital fund of Microsoft, making minority equity investments in early-stage enterprise and business-to-business software startups. It launched in 2016 under the name Microsoft Ventures and was rebranded M12 in April 2018. The fund is replenished annually from Microsoft's balance sheet rather than raised from outside limited partners, and it concentrates on companies whose technology aligns with Microsoft's priorities in artificial intelligence, cloud infrastructure, cybersecurity, developer tools, and vertical software. By its own count the fund maintained roughly 140 active portfolio companies and more than 50 exits as of 2026, and it operates from offices in San Francisco, Seattle, New York City, London, and Tel Aviv. M12 is distinct from, and far smaller than, Microsoft's separate strategic stake in OpenAI, which was negotiated by Microsoft's corporate dealmaking organization and not by the venture fund.
Microsoft consolidated its scattered startup activities into a single brand, Microsoft Ventures, in 2016. Nagraj Kashyap, who had founded and run Qualcomm Ventures for more than a decade, joined Microsoft that year as a corporate vice president to build and lead the new investment arm. The group set out to back early-stage enterprise startups, typically at Series A through Series D, in areas adjacent to Microsoft's business.
The name Microsoft Ventures had earlier been used for the company's startup accelerator and seed program, which created confusion about whether the group was an accelerator or an institutional investor. To separate the two, Microsoft renamed the investing arm M12 in April 2018 and moved the accelerator and later-stage support programs under the name Microsoft for Startups (the accelerator had been called Microsoft Accelerator and, for a period, Microsoft ScaleUp). According to the firm and contemporaneous reporting, the M in M12 stands for Microsoft and the 12 refers to the number of letters in the word entrepreneur. (This origin is sometimes misstated as referring to the letters in Microsoft, which has nine, so the figure is best attributed to the entrepreneur explanation that M12 and outlets such as GeekWire and Wikipedia give.)
Kashyap left M12 in early 2021 to become a managing partner at SoftBank's Vision Fund. Michelle Gonzalez succeeded him as corporate vice president and global head of M12 in 2021. Gonzalez had previously been managing partner of Area 120, Google's internal incubator, and earlier held product roles at Apple and an investing role at Comcast Ventures.
In January 2023, Gonzalez announced a sharpened strategy that tied M12 more tightly to Microsoft. The fund narrowed its focus to AI, cloud infrastructure, cybersecurity, developer tools, and vertical SaaS, with selective frontier bets in autonomous systems, Web3, and gaming, and it shifted toward earlier Series A and B rounds. Gonzalez described the change as leaning into the M of M12, meaning the fund would draw more heavily on Microsoft's network, customers, and co-selling channels to help portfolio companies. As of 2026, M12 frames its themes around AI applications, security for AI, AI cloud infrastructure, AI data operations and models, and deep tech, and it describes its stage range as seed through Series B.
M12 is a wholly Microsoft-funded venture vehicle. Rather than closing a fixed fund from external investors, it receives a yearly capital allocation from Microsoft. Fortune reported that Microsoft allocated about 275 million dollars to M12 for fiscal year 2024, and that in recent years the fund had deployed roughly 150 million to 250 million dollars annually, often less than the full allotment. Those figures place M12 firmly in the category of an ordinary corporate venture investor writing minority checks alongside other firms.
This is a different activity from Microsoft's headline strategic investments in AI. Microsoft's multibillion-dollar partnership with OpenAI, its 650 million dollar arrangement with Inflection AI in 2024, and large acquisitions such as Activision Blizzard were handled by Microsoft's corporate business-development and strategy organization, not by M12. Fortune put it directly, noting that M12 cannot take credit for its parent's early OpenAI investment because that deal was handled by corporate leaders. Chris Young served as the executive vice president responsible for that corporate business development, strategy, and ventures group, a role he held from 2020 until his resignation, disclosed in a regulatory filing in January 2025. Young's organization oversaw the large strategic deals; M12 under Gonzalez runs the day-to-day venture portfolio. Keeping these two functions separate is important to any accurate description of the fund: M12 makes venture bets, while the OpenAI stake is a corporate strategic investment outside M12's mandate.
M12 has at times managed its portfolio actively on the secondary market. A Microsoft spokesperson, cited in reporting on secondary sales, said the fund sold fewer than 10 of its more than 100 portfolio companies as secondaries in fiscal 2023.
M12 invests primarily in enterprise and B2B software. Its stated focus areas have centered on artificial intelligence and machine learning, cloud and data infrastructure, cybersecurity and security for AI, developer tools, and vertical SaaS in sectors such as healthcare and retail. The fund has historically also taken selective positions in frontier categories including autonomous systems, industrial drones, robotics, and, for a period, Web3 and gaming. Increasingly its theses are framed around AI, including AI agents and application-layer software, data operations for AI, and the infrastructure and security needed to run AI systems in production.
A recurring feature of M12's pitch to founders is access to Microsoft. The fund emphasizes customer and channel introductions, co-selling through Microsoft's salesforce, integration with Azure, and executive mentorship as benefits it can offer beyond capital. More than half of the M12 team is dedicated to portfolio support rather than sourcing new deals, according to the firm.
In 2023, M12 and GitHub launched the M12 GitHub Fund to back open-source developer-tools startups at the pre-seed and seed stages, with the firm describing an initial commitment in the range of 10 million dollars and a plan to invest in roughly eight to ten companies a year. Early companies named in connection with the effort included CodeSee and Novu, and the program later participated in rounds for open-source projects such as ToolJet.
M12's portfolio spans security, infrastructure, developer tools, healthcare technology, and hardware. Aggregators such as Crunchbase and PitchBook have reported figures on the order of a few hundred total investments over the fund's life and dozens of exits, including multiple IPOs; exact totals vary by source and date, so they are best treated as approximate. Companies frequently associated with M12 include Cloudflare, the web-infrastructure and security company that went public in 2019; Innovaccer, a healthcare-data unicorn; Outreach, a sales-engagement platform; Kahoot, the learning-games company; and Markforged, a 3D-printing manufacturer that M12 helped back into its 2021 public listing. The table below lists several investments that are documented in primary or contemporaneous reporting.
| Company | Round / Year | M12 role |
|---|---|---|
| Synack | Series C, 2017 | Participated in roughly 21 million dollar round (security testing) |
| Markforged | Growth, 2017; PIPE, 2021 | Backed the carbon-fiber and metal 3D-printing maker; among investors in its 2021 SPAC listing |
| Applied Intuition | Series B, 2019 | Participated (autonomous-vehicle software) |
| Arkose Labs | Series B, 2020 | Led roughly 22 million dollar round (fraud and bot prevention) |
| Innovaccer | Growth | Investor in the healthcare-data platform, later a unicorn |
| Cloudflare | Growth (pre-IPO) | Investor ahead of the 2019 IPO |
| ToolJet | Seed, 2023 | Co-invested via the M12 GitHub Fund (open-source low-code) |
The fund's leadership has turned over across three phases. Nagraj Kashyap founded and led the arm from 2016 until his 2021 move to SoftBank. Michelle Gonzalez has been corporate vice president and global head since 2021 and set the Microsoft-aligned strategy announced in 2023. At the corporate level above the fund, Chris Young led Microsoft's business development, strategy, and ventures function from 2020 until January 2025; that role, rather than M12 itself, was responsible for Microsoft's largest strategic AI deals.
M12 continued to add senior investors to deepen its AI coverage. In August 2025, Peter Lenke joined as a managing partner focused on AI, enterprise, and the application layer across seed to Series B. Lenke had previously led Atlassian Ventures, where he oversaw a portfolio of roughly 70 companies, and earlier worked on corporate development at Twitter and Criteo.
Beyond its main fund, M12 has run thematic vehicles and partnerships, most prominently the M12 GitHub Fund for open-source developer tools. The firm has also periodically organized competitions and challenges for AI startups as part of its sourcing and ecosystem work.
