About us

Key Lime Publishing is an independent publisher founded by former members of the award-winning Mango Publishing team. Collectively, we’ve published more than 1,000 books since 2014, selling over 10 million copies and earning national recognition along the way. Now, we’re channeling that experience into reimagining what publishing can be in a rapidly changing world.

Our mission is simple yet ambitious: to empower new and underrepresented authors, connecting their voices with readers in authentic, meaningful ways, while staying agile in the face of the challenges reshaping the publishing industry. From the rise of AI to shifting global supply chains, inflationary pressures, and industry uncertainty, the landscape of 2026 and beyond demands resilience, creativity, and bold new strategies.

That’s why Key Lime is harnessing the experience of building one of fastest-growing independent publishers in the U.S. over the last decade to create a publishing house tailored to modern authors looking to connect with their audience and new readers.

Our Commitments:

• Authors: Championing diverse, brilliant voices and helping them succeed in a fast-changing industry.
• Readers: Delivering books that inspire, entertain, and inform—always with relevance, quality, and impact.
• Innovation: Implementing technology and new marketing models to make books more accessible and resilient.

Key Lime is more than a publishing house. We’re a community of creators, innovators, and readers who believe that books matter—perhaps now more than ever. Together, we’re shaping the next era of publishing.
