Choosing the right programming language for your startup is not an easy decision, considering the huge variety of available options. And it’s not enough to choose one just because it’s more popular, an experienced developer recommended it or a friend claimed it’s the best of the best. The choice of a programming language, especially for a startup, should be wise and based on sound reasons.

But why is it so critical?

The thing is, programming languages differ greatly from one another. They are used to meet various needs (e.g., PHP is intended mainly for web development, C is for low-level programming, and all-purpose languages like Python, Java, and JavaScript have their own special features). And since they have different syntaxes, each of them offers different performance levels.

If chosen properly, a programming language will help you and your startup:

  • save time and money on the implementation of your ideas,
  • scale the development team if necessary,
  • scale the product, and easily implement new features, and
  • easily and effectively support the product after its release.

If its language is not selected wisely, a startup may suffer tech-related problems from the very beginning such as over-budgeting, overestimation, and a lack of flexibility to follow the demands of the market. All of these may drown the whole startup under bad circumstances.

The Most Famous Python Startups That Became Giants

Many cool startups are built with Python, but leading companies of various industries also widely use this language in their applications and ecosystems. Here, we’ll tell you about some well-known projects that used Python at a startup stage and continue using it now.

Java is a high-level programming language often used for building enterprise applications that aim to scale in the future. Java is commonly used to create applications of different types.


  • Write Once, Run Everywhere
  • Security
  • Has a great number of APIs


  • Speed
  • Doesn’t look native on the desktop

Java includes security as an integral part of the design and is considered to be the most secure programming language. If you aim to build a product with a variety of features, Java can accomplish different tasks such as networking, database connection, and XML parsing.
However, in comparison with C and C++, Java is significantly slower and memory- consuming.

C++ is one of the oldest programming languages and is known as the mother of all languages. A lot of programming languages are built using C++ as the base.


  • Combines features of both high-level and low-level languages
  • Scalability
  • Compatibility with C


  • C++ is very specific and niche-oriented

In general, C++ is not the best choice for a startup, unless you have very specific performance requirements. When your goal is to quickly build an MVP, it’s better to choose another language that enables fast prototyping.

Ruby is an open-source language that allows for simple and fast creation of web applications. Here are its benefits for your startup:


  • Time-efficient
  • Cost-effective
  • Compatible with different technologies


  • Slow performance
  • Lack of flexibility

Ruby has a lot of default modules and plugins out of the box, which is great for standard functionality. However, if you want to develop a product with specific functionality, Ruby can be hard to adjust.

By the way, we recently wrote the post “Ruby on Rails vs. Django“. The article provides a detailed overview of the similarities and differences between the two frameworks, as well as the strengths and weaknesses of each, helping readers to determine which one is better suited for their specific needs.

Choosing a Startup-friendly Programming Language

Consequently, from what we’ve learned above, a startup-friendly programming language needs to help the company:

  • build an MVP as quickly as possible to attract investment and test the hypotheses,
  • easily implement new features,
  • create fast iterations during the development process,
  • scale the business,
  • scale the development team working on the project,
  • most likely, integrate with other software related to the product, and
  • easily and effectively support the product after its release.

Python is often considered one of the best startup programming languages, as it satisfies all of these requirements.

Certainly, the choice of language depends on the type of product programming startups aim to develop and its owners’ business goals. This means that, despite Python’s versatility, in some cases another language will be more effective. It’s not about Python being unsuitable for certain kinds of products. It’s just that sometimes you can do the same things you can do with Python more efficiently using another language (e.g., if you need a streaming service). But, in 90% of cases, Python remains the most legitimate programming language for new companies, and our rich experience in product development proves this statement.

Reasons to Use Python for Your Startup

Having been in use for more than 30 years, Python is obtaining more and more admirers in developer communities all over the world. Forecasts say it’s on track to having an incredible amount of traffic by 2020.

There are many programming languages. And, of course, each has its own advantages. It would be unfair and inaccurate to say there’s only one specific language worth your attention (otherwise, the others just wouldn’t exist).

That said, when we say that Python is the best programming language for a web startup, we mean it will give you:

  • the potential to develop a quick MVP,
  • easiness in finding product support,
  • scalability and flexibility,
  • a high level of security, and
  • efficiency in terms of time and money.

Python, together with Django, is a combination that our team has tested far and wide for many years. And, as a technical partner, with each project we successfully complete using Python, we clearly see it’s the best choice to use to help a client launch a startup.
