91探花

As summer comes to an end, September 2025 has been a busy period for funding announcements.

This month, billions of dollars have been raised by companies looking to tackle the next big thing in robotics, AI, biotechnology and more.

But the interesting thing about September鈥檚 roundup isn鈥檛 the diversity of ideas, it鈥檚 also the diversity of investments.

Whilst some companies are raising billions, others are raising less than 拢1.5 million. This shows huge investor appetite for companies of all sizes.

But this month鈥檚 roundup is also a reminder that AI isn鈥檛 the only thing turning heads. Companies are also investing in important areas like healthcare and the environment, including areas like de-extinction.

So, let鈥檚 take a look at the companies that investors have backed this month.
