This collaboration is about propelling growth and providing our underwriters the tools to make better decisions at an accelerated pace, ultimately driving our ability to serve more clients with greater insight.

Peter Zaffino
CEO at AIG

We see AI agents as the next evolution of commerce—autonomous systems that can predict, suggest, and find the products and services consumers need. This means AI that can find the best price for ‘that dress’ or can make everyday purchases on your behalf at the right time. This is only possible with a secure foundation at the base built on consent, privacy, transparency, and security. We are delighted that Anthropic is a key partner of Visa to make this dream a reality and shares our values and principles around responsible data usage (and we trust Claude to underpin this vision). Because when AI is moving money, safety and trust are non-negotiable.

We’ve been developing capabilities powered by Claude since 2023 within AIA Labs. Claude powered the first versions of our Investment Analyst Assistant, which streamlined our analysts’ workflow by generating Python code, creating data visualizations, and iterating through complex financial analysis tasks with the precision of a junior analyst.

CTO, AIA Labs at Bridgewater

Claude serves as a remarkable reasoning-powered companion. Its ability to shift smoothly between quick execution and deep analysis, with fine-grained control over both, is exactly what’s been missing in AI systems. Anthropic is a go-to technology & partner for AI workloads that require reliable intelligence at scale

Through our training program with Anthropic, we’ve seen portfolio companies adopt Claude Code with remarkable results. Development teams are completing complex tasks in hours instead of days, and we’re hearing from previously skeptical engineers that they can’t imagine working without it. The productivity gains we’re seeing validate why we invested early in helping our portfolio companies leverage Claude's capabilities.
