Door No. 3

Door No. 3, often shortened to DN3, is a growth marketing agency in Austin, Texas that combines strategy, messaging, creative and media buying under one roof. It works mainly with healthcare, consumer packaged goods and government organizations, and says it has also served education and transportation clients.

The agency follows a four-step process: clarify where a message loses people, craft a narrative the team can repeat, run an integrated and targeted campaign, then convert attention into measurable revenue by tracking data. Its messaging practice uses the StoryBrand framework, and the site says the team is certified in it. The agency also runs an AI Lab section alongside its main capabilities.

• Messaging and positioning: StoryBrand-based brand narratives
• Integrated campaigns: media planning and buying across channels
• Momentum: a retention and loyalty offering focused on growing wallet share
• Brand strategy and creative: identity, naming and design work
• Digital and performance marketing: growth and performance campaigns, plus AI-assisted work

Client logos on the site include Texas Tuition Promise Fund, Texas College Savings Plan, TEXASable, Texas.gov, BSW Health, Waterloo, TEXpressLanes, Cintra, Santikos, CapMetro and Carehive. Featured case studies cover Texas x Texas, which the agency says helped drive 2 million new app downloads; Malk, a product campaign built on fewer ingredients; Black Ink, a new look and voice for healthcare providers; and a new name and identity for the Permian Basin Reability Center. Work pages also cover Baylor Scott & White Health.

The team page names Prentice Howe as Principal, Ashley Steele as VP of Account Services, Becca Hovland as Creative Director and Ines Morel as Head of Design. The agency states that it has worked with organizations for 30 years and that it values impact over awards. Community involvement includes campaigns for the Austin Humane Society and Habitat for Humanity, mentoring with Big Brothers Big Sisters of Central Texas, and Austin SkipFest, an annual fundraiser at Mueller Lake Park that it says benefits more than 3,500 foster children in Central Texas.
