DeepSeek, the Chinese AI company that rattled Silicon Valley earlier this year with its efficient open-source models, is preparing to at least double its headcount across all departments. The expansion comes on the heels of a $7.4 billion funding round, one of the largest ever raised by a Chinese startup.

Here’s what makes that hiring target remarkable: DeepSeek currently operates with a team of roughly 150 to 170 people. For context, OpenAI employs thousands. The fact that a company valued at over $50 billion runs leaner than most mid-sized accounting firms tells you something about how efficiently Liang Wenfeng’s operation has been built.

A funding round built for defense, not just offense

The approximately 50 billion yuan (around $7.4 billion) raise marks DeepSeek’s first time taking external capital. The round reportedly elevates the Hangzhou-based company’s valuation to somewhere between $50 billion and $59 billion, depending on which post-money estimate you trust.

The investor list reads like a who’s who of Chinese corporate power. Tencent and CATL, the world’s largest EV battery maker, both participated. But the most striking detail is that founder Liang Wenfeng personally contributed around $3 billion to the round, making him the single largest investor in his own company’s fundraise.
