M12 is Microsoft’s venture capital fund, investing from seed through Series B in AI applications, AI security, cloud infrastructure, data operations and foundational enterprise technologies.
Its investment strategy is closely aligned with Microsoft. The fund works to connect portfolio companies with customers, commercial opportunities and relevant Microsoft teams rather than offering capital as an isolated relationship.
Its work with Inworld included connections to Xbox and other game studios. That illustrates how a corporate investment relationship can help a startup reach a particular product ecosystem and the companies building within it.
