Senior, nimble, and built for how marketing works now.
Firefly is a principal-led team for pharma, medical device, healthcare, and telehealth brands. We plug into your brand team, move fast, and stay accountable to outcomes.
Who we are
An extension of your brand team, not another agency layer.
Firefly Marketing is a Chula Vista, California company led by Irvin Carlin, who has scaled a branded weight-management product’s performance media to roughly $18MM a year, grown its telemedicine channel from about 5% to nearly a quarter of the business, run telehealth-only brands end to end, and managed more than $30MM a year in paid search at agency scale.
We lead with pharma, and we are open to medical device companies, healthcare providers, and digital health and telemedicine brands that need the same mix of performance and compliance.

How we work
Nimble, flexible, and modern.
Nimble
A small senior team means no handoffs to juniors and no waiting on layers of approval.
Flexible
Audit, project, or ongoing co-execution. We fit around your team and agencies, not the other way around.
AI-enabled
AI-assisted analysis, reporting, and creative variation speed up the busywork, and a senior person checks every output.
Compliance-minded
We work with your MLR, privacy, and legal teams and with compliant tracking tools such as Ours Privacy, plus HCP platforms such as Wrango.
