Synthesia-Wayve Backer Air Street Closes $232M Fund to Expand AI Investments

The pace of investment in artificial intelligence startups continues to increase. As a result, venture capital firms are competing to identify early winners. Many are also differentiating themselves by backing companies built around AI from the start. UK-based Air Street Capital follows this focused approach.

An AI-Focused Investment Strategy

Air Street Capital invests exclusively in companies that use artificial intelligence at their core. It supports businesses where AI strengthens products, improves competitiveness, and drives long-term growth.

The firm was founded by Nathan Benaich. Since its inception, it has invested across Europe and the United States. It typically partners with founders building advanced AI systems, infrastructure, and applications. In most cases, these companies rely on strong research and technical depth.

Launch of Its Third Fund

The London-based firm has now raised a $232 million fund. This marks its third investment vehicle. With this fund, Air Street plans to back AI-first startups across North America and Europe.

The firm will lead early-stage rounds with investments between $500,000 and $15 million. In select later-stage deals, it may invest up to $25 million.

Nathan Benaich began investing in AI in 2013. Over time, he developed a clear thesis. According to him, the most important companies of this generation will be built around artificial intelligence. This belief led to the launch of Air Street Capital in 2019.

Positioning as Europe’s Largest Solo GP Firm

With the launch of Fund III, Air Street has become the largest solo general partner (GP) venture firm in Europe.

The firm has backed several AI companies. These include Synthesia, which creates AI-generated enterprise videos, and Wayve, which develops self-driving technology. It has also invested in Profluent, a company focused on AI-driven gene-editing systems.

In addition, Air Street has seen exits through acquisitions by companies such as Amazon and SoftBank.

Focus Areas for Future Investments

With its new fund, the firm plans to expand its investments in areas where AI creates new products and markets. Its focus includes software, developer tools, infrastructure, AI-driven science, and defence technologies.

“Our focus remains on AI-first software, developer tools and infrastructure, techbio and science, and defence and security – the areas where AI is not simply improving the status quo but enabling entirely new kinds of products and companies to be built,” says Nathan.

Building Influence Beyond Capital

Apart from funding, Air Street has built a presence within the AI ecosystem. Its annual “State of AI” report is widely followed by industry participants.

The firm also hosts events that bring together researchers, founders, and engineers from different regions.

“We will also remain committed to speaking out when the ecosystem needs it. Whether that is our work on the spinout.fyi – where key Air Street reforms to the university spinout playbook were accepted by the UK Government, or our Air Street Press essays and policy memos, we believe that if something is worth saying, it’s worth saying publicly,” says Nathan.
