Finding an agency to build an app for your business can seem like an overwhelming challenge. You want stunning UX design and rock-solid development, of course. But wouldn’t it also be nice to find a shop that understood strategy — one that could help you envision the best possible app before spending loads of money on the launch and ongoing audience development?

One industry source ranks 1,734 mobile agencies, with new ones popping up quite regularly. Here at (a Sailthru company), we work with a massive number of mobile agencies and partner with the world’s biggest brands like Target, Sephora, Coca-Cola, MATCHES FASHION, Mondelez International, Birchbox, and more to deliver their push notifications and in-app messages to drive more engagement for their app.

We’ve got the insider’s understanding of which firms drown in their hype and which overcome it, delivering superior results, every time, and we’ve identified ten U.S. firms that consistently impress. They’re the ones I’d head to if I were a business with an app proposal. If that’s the situation you’re in, we’re happy to make an intro to any of the firms listed below. You can reach us at, and you can read more about our agency partner program here.

Prolific Interactive, New York


Prolific was founded seven years ago by Eric Weber and Bobak Emamian, who met while playing baseball at Quinnipiac University. They quickly realized that some of the best talent and clients in the world were just a few miles south, and relocated to Brooklyn. Now, Prolific is all about the consumer experience. They built the first iOS app for SoulCycle, enabling the company’s devoted cyclists to book classes quickly — crucial, given that the most popular SoulCycle classes often sell out in just a minute or two. Prolific has also worked with other well-known brands such as American Express, Saks Fifth Avenue, and Old Navy.

Mutual Mobile, Austin

Mutual Mobile

Mutual Mobile, founded by five Austin college students back in 2009, is at home on the bleeding edge. For years, that’s meant developing mobile apps for big players such as Flexdrive and J Hilburn. It recently built the Under Armour Shop, which sifts data from Under Armour’s connected fitness community — 170 million strong — to suggest gear. Now, Mutual Mobile refers to itself as an emerging technology company, and is amping up its capabilities in virtual reality and internet of things technology.

Raizlabs, Boston & Oakland


Like other top agencies, Raizlabs is moving beyond the confines of traditional mobile app development to integrate technologies from artificial intelligence, internet of things, virtual reality, and augmented reality. Their clients have ranged from Costco to Six Flags to athenahealth. One of their recent successes: the BlindWays app, developed with Perkins School for the Blind, which makes it easier for people who are visually impaired to use public transportation.

Fueled, New York


Fueled describes itself as a mobile product agency. They’re less interested in building whatever projects come in the door than they are in working with clients to understand their business objectives, and to build something that will reach them. They’re serious about mobile strategy and planning, as well as design and development. They work primarily with two types of clients: Big brands and venture-funded startups. Recently, that’s meant Rite Aid and IBM as well as Warby Parker and QuizUp.

Fuzz Productions, New York


Fuzz Productions was founded in 2001, making it among the pioneers in mobile development. In the past 16 years they’ve launched hundreds of iOS, Android, and responsive web projects for Fortune 500 companies and also for innovative startups. They’re committed to agile product development, and their employees all work in-house from offices in Brooklyn, Boulder, and Los Angeles. Their recent work includes apps for Shake Shack, Wegmans, and CBS. And oh, they’ve won two Cannes Lion awards.

Bottle Rocket, Addison, Texas

Bottle Rocket

Calvin Carter founded Bottle Rocket the day after the App Store opened to third-party developers, back in 2008. Since then, it’s won clients such as Starwood, BET, and Chick-fil-A. Bottle Rocket prides itself on the development of native frameworks, platforms, and solutions that are unique to Bottle Rocket. The firm works across all sorts of platforms — iOS, Android, streaming devices, wearables, virtual reality, and television, and has recently opened offices in New York and London.
