After 30 years in software, weird definitely works

We have the mac sauce

We shared space with Soundgarden in the 90’s, but now we have a bulldog

Our story is hard to imagine, but when we started out there were only 250 websites on the Internet and our first major contract was assisting Steve Jobs on the software that ran the “Cube.”

In the early 90s, the four of us loaded a U-haul leaving Palo Alto behind, and set up shop in Bellevue, a tech rich suburb of Seattle.

Strategically headquartered, our office today is a stone’s throw away from the Google and Microsoft campuses where we cherry pick our developers.

From our Bellevue project management offices and our Redmond coding location, we thrive on building out custom software systems that optimize your software’s performance, taking into account your current and future needs.

We deliver something the giant corporations can’t; personable solutions created by real people.

At Seattle Software Developers, we work from the ground up and that’s good because in today’s world of technology it’s the apps that are built on good code that make it. 

That’s Lucy, the resident bulldog.

We’ll burn the midnight oil for you.

We were there before AOL, Ebay, Myspace, Facebook, and even Instagram.

Before smartphones and mobile Apps were a thing Seattle Software Developers was building software. Since 1989, we have been pushing the frontiers of digital technology and app development and in the process we blazed a trail that others would soon follow.

We are the Pioneers in our field, and we create solutions for clients that work.

UX/UI Design

We live code and breathe design

We’re a colorful assortment of tech nerds, coders, and designers who happen to love what we do. Most of our employees got their start at Microsoft, Google, or Amazon. The experience gained at these tech giants is evident in our work.

Our collaborative spirit extends beyond the office: we’re a close-knit bunch that works together, plays together, and even vacations together.

We’re good at what we do. And we have fun doing it!

After meeting with several other development firms, I decided to have Seattle Software Developers build a lead... generator app for my practice. From out initial meeting where they mapped out the idea on a white board, I had a very good idea of what to expect and when.The team worked efficiently and had excellent communication throughout the build. The app worked perfectly, and performed better than expected. I am very happy I chose them to develop my custom software and have since hired them to build an app for my wife's business too.read more

We were beginning to wonder if we would ever find a solid software development company we could trust. Then Seattle... Software Developers came along. We heard about them from a friend who said they were easy to work with and would take care of us. 3 years later they continue to exceed our expectations. I am not someone who is easily impressed and rarely does anyone exceed my expectations. Our project manager knew when to contact me with important information and when not to contact me just to "check-in". Running a successful practice keeps me busy enough, it's a breath of fresh air to have competent developers who know what they are doing. We are very pleased with the results!read more
