About Test Double

Test Double is a software development consulting agency whose top-tier senior developers work as extended members of your engineering team. Your tools and technology. Our empathetic and flexible senior developers.

We’ll leave your team better than we found it. We aren’t order-taking code-slingers—we aim to be full-fledged, opinionated members of your team. We’re comfortable playing whatever role your teams need most—code janitor, interviewing expert, test creator, whatever.

We’ll help you drive your business forward. Test Double agents are some of the best, most experienced, and renowned developers anywhere. We know how to prioritize what counts—delivering value—on greenfield projects, troubled legacy systems and anything in‑between. We use open-ended contracts that allow you to adjust staffing as you need, while sharing knowledge between engagements to keep everyone on the same page so we’re never the blocker.

We’re teachers, mentors, and seen‑it‑all‑beforers. Starting with your existing tools and practices, we make incremental improvements as you’re ready for them so that our process changes stick. Whatever issues you’re having with your software or your teams—we’ve likely seen them before, and we know how to solve them. Test Double agents are empathetic teachers and mentors, and we can’t wait to work with your team.
