We’re Kevin Sill and Bradford Sullivan of Callan Pharma, and our story is one of turning frustration into a formula for our partners’ success.
Having operated two drug delivery technology companies together since 2013 and navigated the challenges of drug development from the inside, we, the founders, grew frustrated with the conventional CRO model. We experienced the slow timelines, the communication gaps, the lack of agility and the painful pressure of bureaucracy that stifles innovation and drains monthly budgets.
We knew there had to be a better way.
We built Callan Pharma to be the partner we wished we had: a nimble, fearless ally with the expertise to solve complex problems and the agility to move swiftly. We intentionally designed a company where we cut out the red tape, and our partners work directly with us to get straightforward solutions. We speak the language of venture capital and appreciate the urgency of your mission because we’ve been there.
What does this mean for your project? It means no waiting on layers of bureaucracy. It means you get straightforward solutions directly from the founders. It means your urgency is our urgency. This is the approach that allows us to deliver feasibility studies in as little as a month and has led to the successful encapsulation of hundreds of APIs for our partners. Our story is one of turning frustration into a formula for our partners’ success.
