Seeking to stay competitive and relevant, more and more enterprises view digital transformation as a critical catalyst for growth and innovation. By embracing digital technologies, companies can fundamentally change how they operate and deliver value to customers, and enterprises that won't adapt risk falling behind. However, according to Forbes, 70% of digital transformation projects fail since the process is challenging. Therefore, many businesses turn to specialized consulting firms for digital strategy guidance and execution. 

But how to choose a trustworthy vendor among a myriad of digital transformation consulting companies around the globe? To help you make an informed decision and narrow the options, we compiled a list of 15 best vendors renowned for their expertise in digital transformation, from strategy to execution.

Selection methodology

Finding a perfect vendor among dozens of consulting vendors to realize your digital ambitions can be challenging. For your convenience, we filtered the companies on our list through five key criteria:

  • We covered only digital transformation consulting vendors with engineering capabilities to make sure that they would be able to execute the strategies and plans developed during the consulting phase.
  • Our selection consists of midsize and large vendors with 250+ employees on board. Such companies usually provide access to more tech workforce and streamlined processes, facilitating quick project launches.
  • We included companies with 10+ years of experience in digital transformation consulting and software engineering.
  • All the vendors on our list have extensive portfolios of digital transformation projects and client testimonials.
  • Lastly, our coverage is limited to vendors that cater consulting services to medium-sized companies and large clients.

Top trusted digital transformation consulting vendors around the world 

Our selection comprises two types of digital transformation consulting companies: established and emerging. Some notable advisory firms such as Deloitte and McKinsey have been on the market since the late 19th to early 20th century, delivering consulting services for businesses. Despite extensive experience in business consulting, their engineering capabilities are limited. That's why we included up-and-coming digital transformation consulting vendors in our list. Being smaller, these emerging companies offer a more personalized approach to individual projects, providing tailored solutions. In addition, opting for emerging enterprises instead of consulting pioneers can lower the costs of your project, as these growing firms have smaller rates.
