PMM, Navy vet and overall cool guy Langley Barth joins the pod after Mikey and him connected at a Product Marketing Alliance summit in San Francisco (shoutout PMA!).
Langley is full of GREAT PMM advice—from becoming a subject matter expert on your product to getting to know the customer journey, he’s an expert at guiding conversations that “unlock the unknown unknowns.”
Langley also shares how his experience giving presentations in the Navy (who knew!) has informed his career. In addition to being a PMM, he connects veterans to purpose-driven careers through his organization, Civilian Compass.
