Google has agreed to buy cybersecurity startup Wiz for US$32 billion in cash, the company said on Tuesday.

The acquisition will significantly enhance Google's Cloud platform by allowing the company to offer a more comprehensive and robust security solution to its clients.

5. Perplexity AI eyes major funding round

Perplexity AI, an AI search engine startup competing with Google, is reportedly in early discussions to raise between US$500 million to US$1 billion in a new funding round. An anonymous source for Bloomberg who is familiar with the matter confirmed the potential deal, adding that it would double the company’s valuation to US$18 billion.

The potential funding round comes at a time when Perplexity AI is experiencing notable growth and traction in the competitive market.
