Where Elixir brings the most value to your product
Concurrency at scale
Elixir is a strong choice when your product needs to handle many users, processes, jobs, events, or connections at the same time without losing stability.
Fault-tolerant backend systems
Elixir’s OTP foundations help build systems that can recover from failures, isolate problems, and keep critical parts of the application running.
Long-running applications
Elixir is well suited for products that need to run continuously, process background work, manage state, or support business-critical operations over time.
Maintainable architecture
Elixir’s functional approach and process-based design make it easier to keep backend systems understandable, testable, and ready for future development.

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.
Senior Elixir support for architecture, scaling, modernization, and delivery
Elixir consulting
Work with senior Elixir engineers to validate technical decisions, review architecture, identify risks, and plan the next stage of your product.
Custom Elixir software development
Build backend systems, platforms, internal tools, marketplaces, and product features with Elixir as the core technology.
Elixir codebase review and refactoring
Improve an existing Elixir codebase by reviewing structure, reducing technical debt, cleaning up domain logic, and making the system easier to maintain.
Scaling Elixir-based applications
Prepare your Elixir system for more traffic, users, data, background jobs, and product complexity without losing reliability or control over infrastructure costs.
Elixir architecture consulting
Design or improve OTP-based architecture, supervision strategies, process structure, domain boundaries, and backend communication patterns.
Migration strategy to the Elixir ecosystem
Plan a transition to Elixir when your current technology stack limits reliability, concurrency, maintainability, or long-term product growth.
Phoenix Framework web development
Use Phoenix when your Elixir product needs web applications, APIs, dashboards, admin panels, or backend services.
Phoenix LiveView development
Use LiveView when your Elixir product needs interactive interfaces, real-time updates, dashboards, internal tools, or admin panels with less frontend complexity.
How we start working on your Elixir project
First meeting
We discuss your product goals, current technical situation, and the Elixir challenges you want to solve. This helps us understand whether you need consulting, team extension, modernization, scaling support, or project-based delivery.
Technical context review
We review the project scope, existing architecture, codebase, requirements, or technical risks. The goal is to identify where Curiosum can bring the most value and what cooperation model fits best.
Elixir development or consulting
Our senior engineers join the project and work on the agreed scope - from backend architecture and OTP patterns to refactoring, feature development, performance improvements, or technical recommendations.
Ongoing delivery and improvements
We keep communication clear, review progress regularly, surface risks early, and adjust priorities as the product evolves.
Choose your cooperation model.
Work with high-level Elixir engineers.
Elixir team extension
Add senior Elixir engineers to your team when you need extra expertise, faster delivery, or support with complex challenges.
Project based
From building a new application to modernizing an existing system and scaling it for growing user demand without losing cost control.

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 have delivered over 50 projects for more than 30 companies of various sizes - from small to large organizations, with several clients trusting us with multiple initiatives. Every project teaches us new things, patterns, as well as do's and don'ts.
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.
