From the very beginning, all startups face a critically important decision of picking the right programming language. The decision is not an easy one to make, considering the variety of options to choose from, with PHP, JavaScript, and Python being just a few.

And choose wisely you should, since a future-proof programming language can help you avoid these common problems:

  1. scaling the development team up and down,
  2. internal integration,
  3. implementation of new features.

Let’s also not forget the importance of carrying out market research. Out of the programming languages available, not all will be the right fit for your project and clients. Knowing your market will determine the success or failure of your startup.

This is why you want to make sure that the programming language you end up choosing serves the needs of your potential prospects and is beneficial for the growth of your business. In short, if your clients are happy—so are you.

What do you need to start a business? Three simple things: know your product better than anyone, know your customer, and have a burning desire to succeed.

In this article, we’ll show you why you should consider Python as the programming language of choice for your startup. We’ll also give you a few examples of startups already using Python to gain a competitive edge.

How are startups different from other companies?

First things first, let’s talk about startups in general.

In her article for Bplans, Candace Landau writes that the greatest difference between traditional businesses and startups is growth, or rather the pace thereof.

Startups are meant to grow fast, while developing a product they can potentially sell on a large scale, which is not the case for the majority of businesses.

Landau suggests that this explains why most startups are tech startups. Online businesses are limited by neither time nor space; your customers can buy or use your product whenever they want, wherever you are.

But that’s not all there is to it. There are multiple other factors differentiating startups from other companies, with budget, time, and profitability being the most important ones.

1. Budget

At the beginning of their journey, most startups are usually worse off financially than established businesses. Those who have already tried know that allocating capital for your startup is difficult, yet essential for successfully raising your next round.

Traditional accounting for most early stage tech startups is a waste of valuable time.
Lucas Matheson, CEO @ Pinshape
2. Time

A lot of startups need to act quickly to make partners and investors see the potential behind their project. This makes time a key factor.

One of the many advantages of Python is that it allows you to complete a project within a reasonable time frame and faster than, for instance, using Java for the same purpose. This is especially true when talking about code length.

Many programmers agree that with Python you simply write less code for the same functionality. Keep reading if you want to find out why (hint: it’s Django).

3. Profitability

In most cases, startups hope that their product starts generating profit as quickly as possible. Without it, they can’t grow and sometimes even survive.

The reality, however, is that startups are almost always complex undertakings and it takes them a while to become profitable.



Python—the programming language for your startup

That seems like a lot to juggle, no? Especially if you’re just getting started.

Luckily, Python is here to answer your woes.

Listed below are the main reasons why Python is a great choice for your startup:

1. Python is user-friendly

Python is valued and appreciated in the software community for being intuitive and easy to use. These inviting qualities are often the deciding factors behind many startups choosing Python as their programming language.

2. Python is innovative

While a lot of newcomers understandably favor Python over other languages, major-league players like Quora, Instagram, or even Google also rely on code written in Python—why is that?

Because Python is innovative, it is versatile, and it allows you to elevate your service to new heights. Whatever your needs, Python has got you covered.

3. Python is ubiquitous

Python is used everywhere these days, from Reddit to YouTube. Its popularity is on the rise, and the support for it ever-growing. As part of your future-proofing agenda, you would be wise to pick a language for your startup that is here to stay.

4. Python is robust

Startups such as media streaming projects or social networks are very frequently web-based. The web is driven by big data.

What does that mean for you? Complexity and difficulty of processing. Thankfully, Python is well-equipped to deal with such challenges, making it the perfect fit for beginners.

5. Python is scalable

It’s crucial for startups to catch the wave of success and ride it while it lasts, but your business needs to be ready to handle such growth so quickly. That’s where Python comes into play.

The simplicity at the heart of the language means you’ll be able to overcome any obstacles along the way, and continue growing as you please. This, in turn, spells out only good things for years to come.

How the Django web framework helps your startup

While choosing your programming language is the first and most important step, your work is not yet done—you also need to choose your web framework.

Here is where things get a little bit tricky. After all, the selection of web frameworks available is extensive to say the least, and Python is no exception to this rule.

What you need to know is that the most popular Python framework is Django. And for good reason.

Tech startups are much in demand these days. Consequently, building your web application needs to be effortless and enjoyable. Django’s pragmatic design and ease of use meet those expectations head-on, leading to its rapid and sustained growth in popularity.

The three features programmers appreciate the most about the Django framework are support, scalability, and security.


1. Support

A strong community of professionals around the world is one of the greatest aspects of Python.

Django is developed and maintained by the Django Software Foundation, or DSF, meaning that the very foundation of the Django culture has its own code of conduct. How cool is that?

Many other communities out there, like IRC or mailing lists, are unwelcoming and sometimes toxic. With Django, the situation is reversed, and the support is, dare I say, friendly.

Nothing’s ever perfect, of course, and occasional hiccups are unavoidable, but those are generally handled quickly and efficiently. Plus, it is thanks to these policies that a lot of groups like Django Girls not only exist, but flourish.

2. Scalability

More often than not, you can’t easily predict when scalability will become a priority for your company, especially if you’re a startup.

That’s why it’s a good idea to use a language that is easy to maintain and scales great, both up and down.

At its heart, Django is a series of components, wired up and ready-to-go by default. Since these components are decoupled—meaning, independent from each other—they can be unplugged and replaced if and when your project requires more specific solutions.

3. Security

Django has built-in features that prevent a great deal of common security problems from occurring.

The framework masks or hides your site’s source code from direct viewing on the Internet. It achieves that by dynamically generating web pages and using templates that send information to web browsers.

Through this process, your software is more secure than if you used, say, PHP.

Building your MVP in Python

Ensuring the success of your startup requires making many instrumental decisions. One of those is deciding how you should build a Minimum Viable Product for your project.

The MVP is the basic version of your product that doesn't offer all the features you envisioned yet. Instead, it contains the minimum amount of features that still make the product interesting. Think of it as a trial run before you unleash your product in all its glory.

Starting out with an MVP is advisable because:

  • It allows you to validate your idea before you build the entire product,
  • It saves you time and resources by helping you get feedback on the product,
  • It lets you build your client base early.

When you make the decision to build the MVP, you need to decide on the programming language to build it in. For that, Python is the clear choice.

With MVPs, time is of the essence. After all, you'll want your product to become available before someone else comes up with a similar idea and fills out the niche you're aiming at. Python is easy to write in and offers many ready-to-go libraries, which means the development process will be fast. In fact, if you compare building an MVP in Python with building it in Java, it's weeks vs. months before the MVP is finished. That’s right, you can build an MVP in a matter of weeks—we’ve done it before.

Additionally, building your MVP in Python requires fewer developers than in some other programming languages, reducing the necessary budget.

One thing we can all agree on (I hope?) is that startups are pretty great. It’s exhilarating to try and launch one. It can also be pretty scary. And hard.

So before you get down to it, remember that doing your research and choosing your programming language are the best things you can do to start off right. Not that it’ll be smooth sailing from there on out.

Startups are not like traditional businesses, and you would be wise never to forget that. Growth is a central difference, but so are budget, time, and profitability. Fortunately, they can all be addressed and rectified, at least to a certain extent, by the right programming language.

Python excels in all these areas—with help from its trusted web framework, Django. It overcomes any challenge you place before it with efficiency, speed, and quality unmatched by any other language.

Starting up? Start up with Python.
