Collaborative Drug Discovery (CDD) is a software company founded in 2004 as a spin-out of Eli Lilly by Barry Bunin, PhD.

CDD Vault is a modern web application for chemical registration, assay data management, and SAR analysis.

The product is meant to expand the company's scope from working with mostly preclinical researchers to being relevant for clinical and post-approval stages of drug development, including: Pharmacovigilance or Drug Safety, Regulatory Affairs, Competitive Intelligence - also referred to as Pharma Intelligence within its industry, and Pharmacoeconomics as well as investors and publishers of medical content.

The capability for inter-group collaboration attracted attention from the Bill & Melinda Gates Foundation, who in 2008 awarded CDD with a two million dollar grant being used to support researchers combating tuberculosis.

These molecules and their associated screening data are available via CDD Public, as well in as the National Library of Medicine's PubChem and the European Bioinformatics Institute's ChEMBL database.
