Which new companies are using Erlang and Elixir? #MyTopdogStatus

by Erlang Solutions

Last year we launched #MyTopDogStatus to share and celebrate some of the fantastic companies using Erlang and Elixir technology. Since then, the Erlang and Elixir community has continued to thrive. Last year, our friends at Code Sync had a wave of brand new people using Erlang & Elixir attending their events, there were representatives of 53 new companies added to the list! And that’s on top of many repeat attendees. The BEAM community now has at least 1,300 companies using Elixir in their tech stack and there are 3 new Elixir jobs advertised on average per week.

The benefits of BEAM technologies remain the same as they were last year, the concurrency model means higher uptime, so less lost sales or angry users when something goes wrong. Both programming languages result in a reduction of code, making it easier to manage, reducing the cost spent on development and making it easier to update. Code reductions also allow companies to reduce the cost and energy demands of their physical servers, which is a benefit to the bottom line, and the planet. Both languages support hot coding so you can have changes made in minutes, not months allowing for a more agile system. Regardless of what benefit is the core motivator, BEAM-based technologies of Erlang and Elixir are almost always the secret sauce in the tech stack of large household name brands who need to handle large volumes of users and data.

So with all those benefits to take advantage of, who were the new top dogs to join the pack and start reaping the benefits of Erlang and Elixir in the last year? Let’s find out.


The biggest of the new kids on the block is Samsung, a company which needs no introduction. With nearly 300 million mobile devices shipped and 2 billion dollars in revenue a year. Given the number of users, verticals and traffic Samsung handles, it’s no surprise that they are looking into incorporating BEAM technologies in their tech stack. This year, our very own Robert Virding, one of the co-creators of Erlang joined them in their Silicon Valley office to present a Meetup on the Erlang Ecosystem. Our team will be continuing to work with them on Erlang training and onboarding.

Cross River Bank

Cross River Bank is an innovative and ambitious take on banking. They combine the traditional features of a state-chartered bank with the flexibility and ambition of a FinTech. Their product features an extensive suite of services as a banking-as-a-platform offering, including lending, payments and risk management. Their smart work with technology partners allows them to focus on growing their business without compromising on technological innovation. As you can imagine, downtime in a sector dealing with large financial transactions needs to be minimised, so it’s no surprise to see BEAM-based technologies in their stack.


TubiTV is an entirely free alternative to video streaming services such as Netflix or Amazon Prime. It is America’s largest independently owned streaming services and operates on an ad revenue model as opposed to a user subscription model. There are over 15,000 videos available to stream at any one time. Dealing with that level of data is always going to be a good use case for a language like Elixir, you can learn more about some of their Elixir implementations over at the TubiTV Github page.


Handzap is an agile, mobile-first app designed to make the gig economy easy available in 32 languages and over 100 countries. People can post tasks, review applicants and chat using instant messaging, video messaging, and voice calls, all from within the app. This makes it easier and more convenient than ever to post, publish, manage and ensure satisfactory delivery for applicants and job posters alike. Due to its ambitious nature, Handzap had a number of unique requirements for its chat functionality, particularly around user privacy. The MongooseIM team at Erlang Solutions know that no two sets of users are the same, and are specialists in creating customised, reliable instant messaging solutions. We helped them build a future-proof messaging platform that integrated seamlessly with their application whilst making sure all their specific requirements were met.

Danske Bank

Danske Bank is Denmark’s largest bank. A Fortune 500 company with over 145 years of history. It has grown to be one of the biggest banks in Northern Europe and the world. BEAM-technologies are perfectly suited to the high-value transactions of the financial services industry, and RabbitMQ (built in Erlang) specifically is often used in technology stacks to handle microservices.


Digital advertising requires huge amounts of real-time decision making and needs to be able to handle significant spikes and loads. OpenX handles over 4.5 trillion data events per day, significantly more than 10 million per second. As we have seen with AdRoll in the past, Erlang’s concurrency is perfect for managing the high volumes of concurrent users required for the industry.


SnatchBot is a fantastic new platform that aims to make the potential of chatbots available to everyone, including non-technical audiences who can’t write a single line of code. The SnatchBot Builder uses building block templates to allow you to publish your bot to mobile devices, web apps and chat services like Facebook Messenger, Slack and Skype. As we mentioned with Handzap, the MongooseIM team are world-class experts at developing innovative and ambitious instant messaging solutions and were happy to help on such an exciting project.


Siemens is the largest industrial manufacturing company in Europe, with nearly half a million employees. They cover a diverse range of industries including Energy, Healthcare, Infrastructure and cities. If you look into any company of this size and scale, you’re likely to find a BEAM-based technology somewhere in their stack, and Siemens is no different.


We mentioned PepsiCo’s use of Elixir in their tech stack to power business-critical solutions in our article last year. This year, our team will continue to work with them to train, upskill and grow the use of Elixir in their tech stack.


SITA (Société Internationale de Télécommunications Aéronautiques) a large scale organisation that specialises in telecommunications and IT for the aviation industry. It is a member-owned organisation comprised of over 400 airlines major airlines ensuring the technology and communications of all flights are up to safety standards.


With all these great companies taking advantage of Erlang, Elixir, RabbitMQ and the BEAM, isn’t it time you looked into how you can get a more reliable, fault-tolerant and dynamic solution. Talk to us; we’re always happy to help.
