Hugging Face has secured $200 million in a Series D funding round led by Salesforce Ventures, valuing the company at $4 billion. This represents a doubling of its valuation since its Series C round last year. Hugging Face now serves over 15,000 enterprises, including 3,000 paid enterprise clients, and is projected to achieve an annual recurring revenue (ARR) of around $40 million this year. Salesforce, the investor, may view Hugging Face as a potential acquisition target in the future. As a company dedicated to open-source model repositories, Hugging Face's foundation is built on open-source principles and it maintains a highly credible stance on AI ethics. Teaming up with Salesforce could bring AI opportunities to the enterprise service赛道. Unlike other startups under pressure to expand, Hugging Face centers around its open-source community, does not overvalue short-term commercialization, yet does not undervalue long-term influence. While China has yet to produce a company like Hugging Face, open-source has become a watershed, requiring a shift away from rigidly assessing companies solely from a commercial perspective.
