Formidable Labs is a team of veteran engineers and designers in Seattle, WA. We develop web apps, train in-house teams, and offer startups and Fortune 500 companies the resources and expertise they need to build products and features quickly. We can integrate into your team, or we can think about your problems so you don’t have to.
We create clean, intuitive user interfaces. We’re comfortable starting from scratch or working within existing brand guidelines, and we can do everything from accessibility to assets.

From startups to the Fortune 500, companies of all sizes rely on Formidable to develop high-performance applications that scale to millions of users.
The second-largest ecommerce site in the world relies on Formidable to build their mission-critical infrastructure—we handle building and testing for all of Walmart.com, and we maintain Walmart’s in-house framework Thorax. We also wrote Walmart’s style guide and built significant portions of their mobile site.
SpeedTest.net by Ookla
Speedtest is a tool that measures Internet performance all around the world. We implemented Speedtest.net’s front end, helped design and develop NetIndex, designed and built the new Speedtest home page, and helped train Ookla’s developers.
Haiku Deck helps you build beautiful presentations. We helped them develop and release new features, improve their web app through robust testing, and build a more reliable and secure API for both web and iPad.
MuleSoft connects the APIs of big business. We designed and built the API Notebook for MuleSoft, an online editor that allows developers to create interactive tutorials and explore use cases for APIs based on MuleSoft’s RAML format.
Polis needed design work on a tight deadline. We plugged in to redo their style guide in Sass, build converting landing pages, and ultimately help turn their prototype into a product.
