growing healthcare startups.

That is Chemistry.


What we do 

Chemistry tackles complex healthcare communication challenges by crafting inventive, audience-centered marketing strategies. Founded in 2013 by Erin O’Brien, with the belief that when people have the right chemistry, the work can shine. As a fractional executive-level marketer, we help growing start-ups by owning the high-level strategy, decision-making, and implementation, but for a fraction of the time and cost.

Why work with Chemistry? 

  • You’re a Seed or Series A/B start-up who need a marketing roadmap, but aren’t ready to hire an executive or senior level marketer. 
  • You have a small, junior level marketing team that needs experienced guidance.
  • You need help hiring the right marketing talent or find the right agency partner.

Healthcare can be complicated. We bring our healthcare knowledge to each and every project,so more time is spent on solving your brand, marketing or communication problem and less time on getting up-to-speed.
