Comparison: characteristics of each company (basic but important)

Let’s start with the comparison of three basic characteristics of each company: years on the market, team size, and tech stack. Each one is carefully explained, so you can assess what kind of company will be good for you, and easily compare the ones that meet your requirements next to each other, on a graph.

Years on the market

A graph presenting how long top React companies are active on the market.

Is an older company always a better choice?

Companies that operate for some time now, have most likely achieved high maturity in their processes. Age translates into their experience, and they probably have high expertise with a few chosen industries.

On the other hand, a company grows over time. The more leaders, the more decision-makers, and, as a consequence, more bureaucracy, and stiff procedures. However, it all depends on the company’s culture, so you may want to check if the vendor seems like a fit.

What about younger companies?

Younger companies often have a fresh look at things, are less opinionated, and have more flexible procedures. They can also have senior engineers on board.

However, in terms of a young company, experience is something you definitely need to check. Do it by looking through their portfolio and talking to previous clients. (Companies from this toplist have documented experience in various projects and industries.)

Team size

A graph presenting how many developers work in various React companies.

We’ve already lifted the veil of secrecy in the previous section, but a few more important details are needed. 

A big company may be a good choice when you need a lot of developers for your project. So your demand is one thing. The second is, how quickly you need them - because you won’t necessarily get them as fast as you’d like.

You shouldn’t identify the high number of developers with the fact that a company can start the cooperation quickly. To be able to do that, a company needs to purposely manage its people and resources to maintain a sufficient buffer. 

Plus, as we’ve said before, in the case of big companies, there are often many formalities to go through before the project can start. That slows down the start.

Is choosing a smaller company a more viable option then? When your demand isn't very high, then most likely yes. 

Most often a small company will speed up the formalities

Plus, small players are also more flexible and able to approach the partnership in a more personalized way, especially when it comes to building a team.

Last but not least, it’s no secret that small companies often care more because they want to prove their abilities and expertise. 

Tech stack

A graph comparing tech stacks of various top React development companies.

Here we don’t assess the specific technologies, but their range in a tech stack.

Why? 

If you’re not sure which technology will be best for your product, only assume React, or have no idea for the backend, a company with a broad tech stack may have a lot of expertise and help you choose.

However, in our opinion, when you’re an expert at everything, you’re actually an expert at nothing.

A very broad tech stack may be justified in the case of a big company, with hundreds of developers on board.

Smaller companies with a narrower tech stack are more likely to actually be experts in their fields. Plus, top vendors won’t persuade you to develop a product in their technologies of expertise if it won’t fit. So if React is not the right choice for you, they will tell you.

Comparison: their approach

What exactly do we mean by approach?

It’s a way a company engages in cooperation. It’s how they perceive their clients, how they deliver business value and value in general.

We assess 6 aspects here:

  • Business-success approach - it measures how much attention a company puts into understanding your business and how advanced are their processes aimed to achieve your business goals.
  • Consultancy attitude - it measures how eager they are to teach your team (by the way of working with it or as consulting) and share their knowledge from various domains, not only coding.
  • DevOps culture - it basically measures how undisrupted the flow of knowledge between team members and the team as a whole is.
  • Time to impact - it’s an assessment of how quickly they will be able to actually improve some part of your product.
  • Ownership attitude - it measures how responsible and, actually, experienced and skilled they are.
  • Partnership attitude - it measures how eagerly they sink into your team and work towards your success as if it was theirs.

As it was before, details are below. Each section has a description to help you grasp crucial aspects and make a conscious decision.

How did we assess that?

A company’s approach is visible:

  • in their reviews and testimonials (How had they engaged in the past projects? What clients are saying about them?),
  • on their website (how do they write about themselves? How do they describe their culture?)
  • social media channels, 
  • and on their blog, or content in general.

Remember: we have great players here. The fact that the company is more to the left, doesn’t mean they don’t provide anything at all. It just means someone puts more attention to that.

And the final question will be which aspects are most important to you.

Business-success approach

A graph comparing how various React companies help their clients to achieve their business goals.

The goal here is to deliver the best business results possible. The bigger attention a company pays to achieving your business goals and not just delivering a set of features, the better chance for that success to happen.

How does it manifest?

  • They understand the business side of projects.
  • They put business analysts in a development team.
  • Developers have not only technical but also business knowledge.
  • There are tech advisors or mentors in a team.
  • They challenge your ideas and make an effort to shape the product properly.
  • They are flexible and adapt the priorities to deliver the highest business value.

Consultancy attitude

A graph showing how eager are various React development companies to share knowledge with clients.

Consultancy attitude is all about sharing knowledge. It can be consulting as a service, but even better if a team shares knowledge with yours simply while collaborating. 

It brings great value when a vendor's team mentors and supports your developers. It may concern technical knowledge, but also project management or design. 

That’s not a typical approach to outsourcing. 

DevOps culture

A graph showing how intensely various React.js companies adapt DevOps culture.

You may associate DevOps with Cloud and CI/CD, but that’s only one side of it. Here we assess the DevOps culture, which presupposes tearing down the boundaries between developers and operations. No boundaries mean close cooperation and an undisturbed flow of knowledge.

That kind of attitude increases transparency, improves communication, and leads to more flawless collaboration. The team is happier and more productive, which leads to a better product.

Time to impact

A graph showing how fast top React development companies can influence a client’s product or service.

With time to impact we try to assess how fast a company can make an actual influence on your product or service. 

Tech advisors in a team or offering workshops help to start the cooperation quickly and make an impact right away.

Time to impact is highly influenced by the company’s processes:

  • resources management,
  • formalities needed to start the project,
  • onboarding time,
  • approach to building teams.

Ownership attitude

A graph showing the level of ownership presented by various React app development companies.

When we talk about ownership, responsibility is one thing, and the other is accepting the possibility of making mistakes and knowing how to deal with them. 

The team with a high sense of ownership works more transparently and takes better care of communication. They have nothing to hide because they own their mistakes.

Ownership can also manifest in a team being able to work independently, not babysitted by a client. 

Seems like the ability to make decisions and high transparency is the needed mix here.

Partnership attitude

A graph showing the level of engagement presented by top React.js development companies.

The partnership means sinking into your team and working towards your business success with high engagement. It means a friendly, but professional relationship.

The vendor’s team is professional and fun to work with at the same time. They are committed, dedicated, and proactive.

There’s nothing to think about here - the more engaged the team is, the better. Unless you want to work quietly and independently - that’s closer to traditional outsourcing, but in this toplist we included companies that prefer different types of collaboration.

Your next moves

Now you can proceed with your research by going through other toplists, or start contacting companies that caught your attention right away.

Before deciding to start the cooperation, remember to:

  • recognize your role in the project,
  • check the details about their portfolio (you can contact previous clients),
  • make sure you will be the owner of the source code,
  • establish clear rules of collaboration and project management.

Pay attention to culture fit and the natural flow between you and a vendor.

Good luck!

How this toplist was created?

All 20 top React development companies presented in this ranking are selected carefully based on the analysis of their:

  • websites (crucial data, what and how they communicate),
  • portfolios (experience, scope, and types of projects),
  • company profiles on various portals,
  • client testimonials,
  • client reviews (from various sources),
  • social media pages (credibility and presence).

They’re all specialists in React who treat React seriously, not as a 10th technology of choice, so most likely you’ll find your best choice here.

But we need to warn you: this is not a typical toplist. It’s more like a detailed comparison of 20 top companies and their approaches to cooperating with clients. 

Why? Because there’s no universally best choice. There’s only the best choice for particular needs.

That’s why we put each company on graphs comparing how much they sink into your team, how fast they make an impact, and how eager they are to share knowledge.
