Elixir experts at your service
Elixir programming language has been our core specialization since the beginning. We started Curiosum with the goal of providing exceptional software services, and in order to make sure that we deliver on this promise, we picked a tech stack that aligns with this vision.
Our expertise in the Elixir language goes back to 2016, and since then, we had a chance to prove our skills and commitment to this technology in various clients' projects, open-source, conferences, podcasts, and blogs.
Our experts worked with 20+ worldwide tech innovators

Why Elixir programming language?
High Productivity
With its easy-to-read syntax, rich ecosystem, and functional design, Elixir stands out as a highly productive programming language favored by businesses eager to rapidly develop and upscale new functionalities.
World's best Scalability
Scalability is Elixir's most frequently cited selling point, and there is a good reason for that. Elixir is based on Erlang VM, the world's most comprehensive platform for parallel processing and distributed processing.
Robust Fault tolerance
Another big Erlang VM's feature is fault tolerance. Erlang was initially designed to bring scalability, distributed processing, and fault tolerance to telephony architecture, and Elixir, with its improvements over Erlang, takes fault tolerance to the next level.
Incredible Ecosystem
Over the years, the Elixir ecosystem has become a unique gem. Phoenix, Phoenix LiveView, Nerves, and Numerical Elixir are just a few incredible frameworks that bring this programming language closer to new domains and respond to modern trends in IT.
We're building exciting Elixir-based applications with our clients

Curiosum enabled our team to develop a complete platform despite their lack of prior knowledge about Elixir stacks. In addition, their team impressed the client with their honesty, integrity, availability, and efficiency.

I'm very satisfied with the deliverables and impressed with the partnership. Curiosum is efficient and communicative team.

Curiosum helped us substantially to introduce OTP and caching concepts into out app as well as formulate the increasingly complex API in a concise manner. They played essential role in the development of our product.

Curiosum team have been great to work with, and we would certainly recommend them. Both of the developers we've had from them have been talented, hard working and a great asset to our team.

Curiosum team has adapted very well to the way we work and has been able to give valuable contribution to our overall product development.

Thanks to Curiosum, the platform now supports 10 times more users within the same server capacity. Also, external and internal stakeholders are happy with the quality of the application. Overall, the team works seamlessly through two-week sprints, using Slack and Jira for project management.

Finding experts in the tech stack we use - Elixir, Phoenix, React, GraphQL - is not easy. Curiosum understood our business perspective well and offered valuable feedback. That is exactly what we expect from our outsourcing partners.

Cooperation that simply works
First meeting
We meet to discuss your specific project needs. You will get to know us better, especially in terms of how we cooperate with our clients and how we approach working with Elixir projects.
After the meeting, you'll receive a full meeting summary, company overview, and cooperation proposition.
Second meeting
Once you review our proposition and decide to work with us, we will schedule a second meeting to prepare for work. Before that, we usually sign an NDA to keep you safe.
After the paperwork, we start to review the code and project scope to prepare specific tasks and share our ideas regarding improvements.
Development & release
We're ready to work and the real development starts. Every feature development cycle involves programming, code testing, code review, quality assurance and deployment.Quality is a must for us.
Therefore, every project involves a thorough continuous integration process to minimize human errors.
Feedback
To make sure that both sides are satisfied with the work, we organize regular meetings. Thanks to the feedback loop, we can grow together.
Mistakes and problems may always happen. It's very important to discuss them as soon as they appear and solve them quickly. That's why we value constructive feedback very much.
Cooperation models that fits your organization
We are working with small, medium, and large companies, and we know that each company has its own goals, strategies, and needs. Regardless of what type of organization you represent, our goal is to be a partner that becomes an integral part of your company.
Outsourcing model
We are responsible for delivering your project from scratch or as a new module within an existing application. To make sure that you're up-to-date with our work, we maintain daily communication and meetings.
Staff augmentation model
We extend your current team, providing expertise and team size for your needs. Our single goal here is to make sure that our part of the team becomes an integral part of yours so that it feels like you hired someone in-house.

Elixir software development company, also known as Elixir dev shop, Elixir software house, Elixir consulting company, Elixir consultancy company, or Elixir outsourcing company, refers to a team of experts in the field of Elixir programming language ecosystem.
It's important to distinguish a general-purpose software development company from one focused on the Elixir programming language. The ability to consult on a specific technological stack is a must if you expect your project to be stable, maintainable, and cost-efficient.
So far, as an Elixir Software House, we provided Elixir consulting or Elixir software development services to around 30 companies of various sizes - from small to large organizations. Every project teach us new things, patterns, as well as do's and dont's.
Elixir is our core specialization on the backend side. Therefore, we don't engage in projects with different stacks unless the goal is to transition to Elixir. We can read code and develop in other programming languages, but to ensure we provide high standards, it's just Elixir for now.
We do, however, specialize in React and React Native on the frontend side. We worked a lot with these technologies; therefore, if you are looking for an Elixir agency that is also experienced in React and React Native - let's talk.
Take a look at the full list of our specializations on the services page.
Most of the projects where we deliver Elixir software development services require full-time engagement from our Elixir consultants. If you are looking for fewer hours, we can talk about this and see what the options are.For Elixir consultancy services, we agree on a specific amount of hours a month. It's a service that requires less engagement, therefore it's up to you and your project requirements.
We understand that you may have some doubts, and that's why we invest a lot in various Elixir-related activities to prove our expertise. Here is a list of resources you may be interested in:
- Blog
- Resources page featuring podcast episodes, webinars, conferences
- Open source initiatives
- Elixir meetups
As an Elixir dev shop, we are determined to share knowledge with the community and learn new things. Apart from the listed above resources, we learn together through regular weekly internal lightning talks and documentation of good Elixir practices that we constantly develop.
