Top Blockchain Development Companies Ranked

This article is the result of my comprehensive analysis to pinpoint Top Blockchain Development Companies in 2019. After working on multiple blockchain-related projects myself, I have decided to make this ranking to help other entrepreneurs choose the best blockchain company out there.

During my research, I analyzed top blockchain performers and their ability to deliver. I have reviewed their portfolio of blockchain projects, checked their online presence including profiles on social media, and reviewed top rating and analytical portals.

What to Look For When Choosing the Best Blockchain Developers

Before we dive in, here is a quick check-list of the things you should pay attention to when choosing the perfect blockchain expert for your project:

  • Number, quality and variety of blockchain projects. A good number of various quality blockchain case studies on the company’s website is an indication the team can live up to its promise.
  • Team size. The larger the team, the more development power and flexibility there is. If the team size is too low, there is a higher risk your project may not be delivered on time.
  • Years on the market. The longer the company has been around, the better. If a company has just been established, there is a much higher risk it can go bankrupt.
  • Online presence. Respected companies are usually active on social media and corporate blogs. Regular updates and a large loyal audience is a good sign.
  • Client testimonials. Positive reviews on trustworthy portals indicates that the company values its clients and delivers high-quality products.

I created a spreadsheet with the above criteria and came up with the following formula to rank the best blockchain development companies:

(2019-C)/2+E+G+J+K*2

Where:

  • C = Year Founded
  • E = LinkedIn Size Rank (7 points for 1000+, 6 points for 500+, 5 points for 200+, 4 points for 100+, 3 points for 50-99, 1 point for 20-49, -1 (negative one) point for 1-19.
  • G = LinkedIn Followers Rank (25 points for 30k+, 20 points for 20k+, 15 points for 5000+, 12 points for 2000+, 10 points for 1000+, 5 points for 500+, 2 points for 200+, 1 point for 100+, 0 (zero) points for 0-99
  • J = Clutch Reviews Rank (5 points for 10+, 4 points for 5-10, 3 points for 2-4, 1 point for 1, 0 points for no reviews)
  • K = Number of blockchain case studies on company’s website

Let’s now take a look at the Top Blockchain Development Companies worldwide. Hopefully, this list will help you find not just a blockchain developer, but a reliable long-term partner for your next blockchain project.
