With the venture capital space finally showing signs of life, investors are opening their wallets to provide funding for both early-stage startups and established companies in cybersecurity, data analytics and AI – especially where some of those technologies come together.

Generative AI platform developer Anthropic was the big winner this month when it struck a blockbuster, multi-faceted deal with Amazon under with the giant company will invest up to $4 billion in the AI startup.
