We suggest you begin with:

• Capital IQ - Data on public and private companies, investment firms, capital transactions, and people with a powerful search portal.
• Cortellis - a pharmaceutical industry-focused database covers not only information on pharma companies, but also covers drug pipelines and global trials, pharma deals, drug sales, and patents. Access is available to HBS AND HU students, staff and faculty onsite at Baker Library (users must be logged in by Baker staff).
• Pitchbook - Information on companies, deals, funds, investors and service providers across the private investment lifecycle.
