About Arbisoft
Arbisoft is a design-first solutions partner for digital leaders who value digital sovereignty—the freedom to own, shape, and scale the technology that drives their business. For nearly two decades, we have helped companies in EdTech, Healthcare, and Travel build and scale products trusted by hundreds of millions of people worldwide.
We deliver design-led solutions built on open-source foundations, with AI woven into everything we do—from how we work internally to how we deliver faster, smarter outcomes for our partners. With 750+ specialists and one of the industry’s lowest talent turnover rates, we operate as a seamless, trusted extension of our partners’ in-house teams.
What Sets Us Apart
Design-First Engineering Excellence
We lead with design to ensure our solutions are not only technically sound, but intuitive and genuinely loved by end users. From day one, our cross-functional teams bring together product thinking, UX, and engineering to minimize rework, reduce launch risk, and deliver experiences that go far beyond typical feature-factory builds.
Open-Source Depth, Without the Risk
For over a decade, Arbisoft has been a leading engineering force behind some of the world’s most widely used open-source technologies—from Open edX and Moodle to Wagtail, Strapi, Django, and FastAPI. Our depth in open-source is not just a technical advantage; it is how we help clients achieve real digital sovereignty: the freedom to own their platforms, control their data, and build on foundations no single vendor can take away.
AI-Accelerated Outcomes, Not AI Experiments
AI is embedded into how we work and what we deliver. We help digital leaders turn AI from buzzword into business impact—building AI-powered products and workflows that improve time-to-market, decision quality, and user experience, grounded in measurable outcomes rather than demos.
Long-Term Partner, Not a Vendor
We partner with category leaders in Education, Healthcare, and Travel not as a vendor, but as a trusted team that integrates into your organization. With decade-long relationships and some of the lowest turnover rates in the industry, our people stay with your product through multiple generations—carrying your codebase, strategy, and institutional knowledge forward.

Advanced Energy United (AEU)
Arbisoft helped Advanced Energy United (AEU) reduce its data crawl time from over a week to less than 4 hours, using a custom-designed distributed crawling mechanism and intelligent data extractors capable of semantic analysis. This resulted in a 97.6% decrease in minimum runtime duration and significant cost savings. Arbisoft enabled AEU to provide updated information to their subscribers more quickly and make better data-driven decisions.
Predict.io - Award-winning Parking Prediction App
Arbisoft developed an award-winning parking prediction app for Predict.io, a Berlin-based startup focused on offline data management. The app accurately detects the driver's parking behavior using real-time sensor data, optimizing SDKs without being resource-intensive. As a result, Predict.io achieved its goal of launching quickly and saw an immediate boost in revenue, resulting in numerous prestigious industry awards.
Wanderu - Travel App
Arbisoft partnered with Wanderu to help them expand their ground travel metasearch engine and fare aggregator business into Europe. We successfully integrated hundreds of carriers with the Wanderu platform and added an iOS app for on-the-go bookings while helping Wanderu's internal team bring on more partners faster and extend the app's value to users. This partnership allowed Wanderu to differentiate itself in the travel management app startup space, and expand further into North America.
Travelliance
Travelliance partnered with us to develop a robust web platform for accounting, reporting, and operations solutions. With load-balanced servers and a modern tech stack, the platform easily handled up to 7 million annual bookings, providing 24/7 support to customers worldwide. Ultimately, Travelliance was able to diversify its service offerings and increase revenues while airlines enjoyed significant savings in time and money.
CodeKer
Arbisoft created CodeKer as an AI-powered alternative to platforms like Phind, Github Copilot, and ChatGPT Plus. Designed to optimize the software development lifecycle, CodeKer identifies coding issues, offers test case support, and streamlines solutions. It's a flexible tool easily integrated into various development environments.
KAYAK - Travel Search Engine
Arbisoft helped KAYAK become one of the world's largest travel search engines by building fully integrated native iOS & Android apps and improving its backend integrations since 2008. With over 50 million downloads, 4.5 stars from over 200,000 happy users, and numerous awards, our dedicated engineers helped establish KAYAK as the search engine of choice for travelers worldwide.
Edx
Arbisoft is edX's official technology partner, providing mobile apps and web solutions for students to access education on the go. Through a meticulously planned short-term strategy, we validated the necessity and demand for in-app purchases, leveraging user feedback and engagement metrics. The successful MVP launch with 50 courses set the foundation for scaling up to over 3,500 courses. Our long-term strategies for both Android and iOS demonstrated our ability to overcome technical challenges and optimize processes for seamless scalability and user experience.
