Background

Lilly is a medicine company turning science into healing to
make life better for people around the world. For 150 years,
Lilly has pioneered life-changing discoveries. Today, its
medicines help tens of millions of people across the globe,
with treatments for diabetes and obesity, Alzheimer’s
disease, immune system disorders, and cancer. Lilly began
using Claude in 2024 through Amazon Bedrock, building
Anthropic’s models into its internal AI platform and into the
tools its developers use to write code.

Impact

In July 2025, Lilly rolled out Claude Enterprise to about
10,000 people, primarily in its research organization. By
April 2026, Lilly had made Claude Enterprise available
across its employee base, the first large pharmaceutical
company to do so. Lilly has five functions that use Claude
most - legal and compliance, technology, finance, oncology,
and research. Within these functions, more than 85% of full-
time employees actively engage with Claude.

Lilly’s early adopters in research are still finding new uses
for Claude. Biologists who once relied on spreadsheet
macros for routine data processing now build working web
apps with Claude in a couple of hours. Chemists can use
Claude to visualize complex data in real time, which helps
them uncover new motifs and configurations of atoms that
would have taken hours with traditional methods.

“Science and technology have always
advanced together. So we gave
Claude to our scientists first. Now
Claude is across the company, and
we can’t imagine going back.
Patients are waiting, so we can’t.”

Diogo Rau, Executive Vice President and Chief
Information and Digital Officer at Eli Lilly and
Company

To support the company-wide rollout, Lilly’s technology
organization built its own controls, then partnered with
Anthropic to shape the enterprise readiness roadmap
underpinning Claude Enterprise. That work includes a
secure private connection, designed to let Claude reach
internal Lilly systems without exposing them to the public
internet, and data loss prevention hooks that audit the data
that passes through Claude. Lilly worked with Anthropic
engineers on the hooks, providing requirements and
helping Anthropic to test them. The team also built an
internal marketplace where teams publish skills and
plugins, with Claude performing a first-pass review of
submissions.

In October 2026, Lilly began piloting Claude Science,
Anthropic’s workbench for scientists, across a wide group of
users. Lilly helped shape its enterprise controls in the same
way, providing requirements and helping Anthropic test
them. The two companies are building these tools together
to help move science forward.
