About Us

Great software is made by great teams.We build both.

Businesses sink billions of dollars into apps and products that barely work, are a pain to deal with, and cost too much. We build software that delivers on promised value, is a joy to use, and isn't painful to change and extend.

What’s a Test Double?

Building great software and great teams

It’s like a stunt double for software testing automation (and an approach championed by Gerard Meszaros). Test doubles stand in for dependencies in order to isolate behavior being tested. While we’re big fans of automated testing to safely refactor legacy codebases, Test Double is also a good metaphor for who we are and what we do.

We’re a software consulting agency, and our consultants are double agents (the good kind!). Our software consultants have an average of 15 years experience and our product consultants have an average of 12 years experience. They embed as remote additions to your team, deliver early and often, pressure test systems, and solve hard problems. We drive outcomes that matter so your team can do their best work.

Founder’s story: Breaking the rules of software development

Developers Todd Kaufman and Justin Searls founded Test Double based on a belief that software was fundamentally broken – but it could be fixed.

OUR Approach

Holistic software problem solvers

We’re not order-taking code-slingers or spaghetti-throwing SCRUM lords. And we’re definitely not butts in seats. We have a very particular set of skills, but we’re not jerks about it.

Instead we meet your team where they are and leave them better than we found them.

Honest & transparent
I always left my interactions with Dustin & Test Double staff thinking that I was working with good people. Honest, transparent & accountable. If I’d had the chance, I wouldn’t mind going riding or making some turns on the mountain with them and sharing a drink at the end.

Kenneth delivered features quickly from week one and enabled us to catch the school sales cycle for our new product. He also did extra credit beyond the sprint: raised the bar on automated testing and proactively helped ramp up new team members. Kenneth reshaped my views on the value an embedded contractor can bring to a team.

Each and every Test Double agent brings a spirit of empathy, humility, and earnestness to their work. They bring new and exciting ideas to the team without a lot of fanfare or ego. They coach and educate without being corrective or judgmental. They empowered our employees to lead efforts and encouraged them along the way. They became part of the fabric of the team—not them and us, but one team.

Speed
The technology backbone developed by Test Double made this project possible at the scale that was achieved. Test Double instantly jumped in to help bring the Curbside Concerts project to life. By providing two developers they worked several weeks to stand up the online interface and a custom scheduling tool to receive concert requests and schedule routes for the driver and artist that enabled us to bring joy to over 700 seniors amidst the height of the pandemic.

Clarity & accountability
From the beginning of the process, Test Double laid out a development timeline with clear deliverables. Our weekly calls reviewed the work completed and allowed for course correction of future work based on feature prioritization and budget. This accountability resulted in a product that was delivered within expected timeframes and budget.

What’s an ESOP? One of our values is that we’re owners. We empower software engineers and product managers to identify problems, build consensus, and develop solutions. (By the way, that’s what makes for good consulting.) Ownership at Test Double is also about being 100% employee-owned through an Employee Stock Ownership Plan. Think of this as a long-term retirement plan offering equitable equity with tangible value and smart reinvestment of profits. Want to learn more?
