We’re a full-service B2B product marketing agency
Olivine Marketing was founded in 2016 to address the growing need for skilled product marketing at early- to mid-stage companies. We’ve since grown to support a range of clients, from pre-seed (and pre-launch) startups to public companies. We're process-driven and results-oriented, so we get sh*t done. Olivine is structured to take the best parts of working with an agency (e.g. executing the hell out of a complex project) with the best parts of working with an individual consultant (e.g. having an additional team member with specific expertise and dedicated project availability). Plus, we've all worked at tech companies, so we're particularly empathetic and attuned to the fast-paced, ever-changing nature of startups and growth-stage companies.
