A marketing agency with heart can build a world of opportunity.

Full Service




Stout Heart is a full-service creative marketing agency based just north of Boston in Portsmouth, New Hampshire (though we never let geography hold us back). Whether you need strategic guidance for a high-level marketing challenge, a brand refresh, a custom website design with robust functionality, or simply a long-term marketing strategy and production partner, we can help achieve your advertising and marketing objectives. We are a relationship-driven marketing agency. Our aim is to build true partnerships with our clients from the start, setting a strong foundation for future work together.

More About Us

Mission Driven

We live by our motto: Be Brave. When we call ourselves a marketing agency with heart, we really mean it. What does that mean? We are incredibly proud to be a certified B Corporation. We put good out into the universe. We do what we believe in. We work with brands we believe in. When evaluating a potential client, we ask ourselves first, whether their brand does good, whether their team is made up of good people, and whether we’ll do good work together. We want our legacy to be positive and we want to help you build yours. Marketing can be a force for good. We promise.

Our size allows us to be nimble and our team to be tight-knit. That’s something you can’t put a price on. We never want our people, our greatest asset, to feel like cogs in a massive advertising agency machine. And we never want our clients to suffer as a result of a majority striated agency org chart. That means you won’t get a dog and pony show from us, for very good reason.

Our portfolio is diverse because we choose clients based on character and values rather than industry niche.
