Companies using Python in 2025

Close to 8k companies, and 200k developers work daily on Python ( source: stack share).  and it is growing more than 10% a year. However, most of the top Tech firms use Python consistently - Google, Facebook, NASA, Instagram, Stripe, SoundCloud, Netflix, Quora - the list goes on.

Quora, the knowledge-sharing platform, started the project with a mindset of using the tech stack of C#, JAVA, and .NET. However,  soon they realized the lack of enough resources and high development time, and unstable software ecosystem. The cost would be high and the pain will be more. They decided on Python keeping critical applications in C++.

Google is a Python supporter since its inception and sponsors conferences like PyCON and EuroPython (the oldest running py conferences). YouTube (previously using PHP), Google Adwords ( the main income source), Google API, and Google web app ( powering Google Maps and Drive) are all using Python in the background.

NASA is using Python for rapid data analysis and data streaming. NASA is investing in open-source technologies for a decade and the SunPy project is one of these open-source software libraries for solar physics using the Python framework. High-performance computing at NASA uses Python-based data analysis tools for climate simulation in space and beyond.

Netflix does a lot of research on ML and recommendation system which are all backed by Python.

Although the enterprise software market is still dominated by C++ and other programming languages, Python is coming up with new and enhanced features to make its presence. However, Data analytics, ML applications, Big Data Tools, Scientific experimenting, Statistical Modelling, Financial Analysis, AI applications, Recommender systems, Medical imaging, Language modeling, and smart devices application - all of these sectors have a preference for Python over other technologies.

Only mission-critical applications which need super-fast execution, Python might not be the best choice.
