I help healthcare and diagnostics startups build brands and creative that resonate with clinicians, patients, and investors, without the cost of a full-time hire or the learning curve of a generalist agency.
I'm André, founder of Assay Creative and a fractional Creative Director focused on healthcare and diagnostics. Over nearly 30 years in brand and creative leadership, I've spent the last decade in this space.
The name isn't random. An assay is a test that reveals what's actually there. That's how I approach branding: uncover the real signal and build around it.
Just as founders hire fractional CMOs for growth or fractional CFOs for financial strategy, I provide senior brand and creative leadership without the full-time cost. I work as an embedded partner, developing strategy and executing it myself, from campaigns and investor decks to sales collateral, trade show experiences, and creative direction for external vendors. You work with one experienced creative leader who understands your business from day one.
I'm currently taking on one or two new fractional engagements. If you're building a healthcare or diagnostics company and need experienced brand and creative leadership, let's talk.
