min read

The software development market is set to reach $608 billion this year, with nearly half of it generated within the US market. The rapid acceleration of digital adoption makes this no surprise. 

Companies are racing to launch software applications that will power their teams, get them closer to customers, and unlock additional revenue streams. And 64% of these companies outsource software development. The reasons for this include cost savings, flexibility, speed to market, agility, and increased access to specialized tools and processes.

While many companies outsource to foreign markets so they can keep project costs as low as possible, equally as many others have a strong preference for working with US-based software teams.  

There are more than 4,500 firms in the US that offer custom software development. Many of these companies also provide website and product development services.

Common Traits of the Best Software Development Companies 

Every software development company on this list has proven to deliver an exceptional customer experience. How exactly do they do it?

Aside from producing high-quality, reliable software, there are a few additional criteria that can make or break a client’s satisfaction with a software project, namely:

  • How well the provider communicated and collaborated with the client
  • If the software was delivered on time
  • If the project stayed within the quoted budget

These factors can be more challenging for software development companies than in many other sectors. There are typically numerous contributors to a software project over a timeline that spans many months and includes countless variables. Even the most precise Gantt charts can fail to keep projects on track.

High-performing software development teams are powered by intelligent planning systems, like Mosaic, that streamline and standardize processes so engineers can obsess over code and project managers can focus on delighting customers.
