Best when you need:
Modernize existing Elixir applications
Improve an existing Elixir system when technical debt, performance issues, outdated architecture, or unclear domain structure slow your product down.
Best when you need:
Scale Elixir systems
Use Elixir’s strengths to handle growing traffic, users, data, and business complexity without losing stability or cost control.
Best when you need:
Strengthen your Elixir architecture
Bring senior Elixir experts into your project to review architecture, validate technical decisions, solve complex backend problems, and guide your team toward a more maintainable system.
Best when you need:
Maintain and develop Elixir products
Keep your Elixir product moving with a senior team that can take ownership of ongoing development, maintenance, performance improvements, and new feature delivery.
Best when you need:
Deliver complete product development
Elixir is our core, but we can also support the full product delivery process when your project needs expertise in frontend, mobile, UX/UI, or product design.
Best when you need:
Focused on Elixir, supported by product delivery expertise.
Our technical expertise is built around Elixir and the BEAM ecosystem. Supporting technologies such as React, React Native, and UX/UI design are used when they help us deliver a complete product experience.
Core technologies
The main technologies we use when building, scaling, and maintaining Elixir-based products.
Elixir
For scalable, fault-tolerant, maintainable backend systems.
Phoenix Framework
For fast, reliable web applications and APIs.
Phoenix LiveView
For interactive product experiences without unnecessary frontend complexity.
BEAM / OTP
For concurrency, resilience, supervision trees, and distributed systems.
Hologram
For building interactive browser experiences directly with Elixir.
Ash Framework
For structured domain modeling, resources, actions, policies, and business logic in Elixir applications.
Nerves framework
For embedded systems, IoT products, and Elixir applications running close to hardware.
Supporting services
When your Elixir project needs more than backend development, we can support frontend, mobile, and product design work.
Choose the right cooperation model for your Elixir project.
Whether you need senior Elixir developers to join your team or a partner to take ownership of a defined product scope, we can support your project through the model that fits your current needs.
Elixir team extension
Add senior Elixir developers to your existing team when you need extra expertise, faster delivery, or support with complex technical challenges.
Best for:
Project-based Elixir development
Bring Curiosum in as a technical partner responsible for delivering a defined Elixir project, modernization, architecture improvement, or product build.

Curiosum has been indispenable to Thoro in growing our cloud and remote-management features for our expanding worldwide fleet. Their extremely capable engineers have fit seamlessly into our team, and have delivered significant value for us and our customers. I would highly recommend them to anyone.
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.

Companies can work with Curiosum in two ways: by adding senior Elixir developers to their existing team or by handing over a defined project scope to us. Team Extension works best when you need extra Elixir capacity inside your current process. Project-Based Delivery is better when you need Curiosum to take ownership of a product build, modernization, architecture improvement, or scaling initiative.
Bring us in when your Elixir application is becoming harder to maintain, scale, or develop further. We can review the architecture, improve code quality, upgrade dependencies, refactor problematic parts of the system, and prepare the application for future product work.
Our team supports Elixir and BEAM-based systems that need to handle more users, traffic, data, background jobs, or real-time interactions. We help identify bottlenecks, improve performance, review OTP usage, strengthen fault tolerance, and make architecture decisions that support growth without unnecessary complexity.
Phoenix and Phoenix LiveView are key parts of our Elixir delivery stack. We use them to build web applications, dashboards, admin panels, real-time interfaces, internal tools, and product features that need reliable backend logic with interactive user experiences.
Yes. Curiosum can take responsibility for a complete Elixir project, from understanding the business goals and technical context to architecture, development, testing, release, and long-term support. This model works well when you need an experienced Elixir partner to deliver a clearly defined product, modernization, or scaling scope.
We work with small, mid-sized, and enterprise companies that use Elixir to build, modernize, or scale software products. The common factor is not company size, but the need for senior Elixir expertise, technical ownership, and reliable product delivery.
