What we do
Strategic thinking, production AI experience, and genuine ownership — at every stage.
We know that every business idea is different.
We build customised solutions tailored to your unique needs and requirements. We rely on a cross-functional approach to ensure a strong core for your business by always considering your digital product's strategic context. We're a locally built company, delivering internationally — working with a complex, worldwide client portfolio across various industries. Increasingly, that includes AI: from advising where it fits your product to shipping RAG systems into production.
AI Solutions
We build AI systems that ship to production — and integrate AI into the systems you already run. From RAG-based answer engines with cited, grounded responses to semantic search, embeddings pipelines, and LLM-powered automation. Built with the discipline AI demands: grounded generation, fail-soft fallbacks, and cost control.
Consultancy
From ideation to long-term maintenance, we help you turn your ideas into reality so that you can focus on what matters — growing your business. We do that by leveraging emerging technologies — including advising where AI fits your product and where it doesn't — and streamlining the development process.
Software Engineering
Custom products and systems built to your requirements. Our developers cover any industry, niche, or user type — and pair technical depth with genuine business understanding. We build with AI-assisted workflows every day — faster delivery, same bar.
DevOps
Comprehensive DevOps solutions that ensure end-to-end pipeline delivery for cloud platforms, enabling faster time to market. We automate critical business processes so your specialists can focus on application delivery, deployment, and maintainability.
Software Testing
Functional, reliable, and secure products. Our QA engineers embed quality into every stage of the delivery cycle — from unit tests through integration to full end-to-end coverage — including evaluation of LLM-backed features, where correctness is probabilistic.
How we work
We're eclectic when it comes to engagement models. They're highly relevant to match the current needs of the IT market and to make sure our clients are fully engaged in the project.
Cross-functional teams
We cover every aspect of development from start to finish. The team owns the direction of the product while working with you to achieve the desired outcome — strategy, UX/UI, web & mobile development, testing, and ongoing support.
Augmented projects
Our developers join your team and work toward a shared goal. Either side can manage the mixed team. This works well for small and large endeavours where multiple teams collaborate on the same project.
Custom
We have a conversation and figure out what works best for you.

Frequently asked questions
What does DevNest do?
DevNest is a Romanian software company that builds tailored web, mobile, and AI solutions for international clients. We cover AI solutions, consultancy, full-cycle software engineering, DevOps, and QA testing across fintech, e-commerce, education, HR technology, and more.
Do you build AI solutions?
Yes — we design and ship production AI systems, not prototypes. We built Business111.com, an AI answer engine for UK businesses that combines retrieval-augmented generation (RAG) with cited sources, semantic vector search, and a fully owned AI content pipeline. We cover the full arc: AI strategy, LLM application development, embeddings and vector search, and evaluation.
Can you integrate AI into our existing systems?
Yes — and no rewrite is required. We add AI capabilities to the systems you already run: LLM-powered features, semantic search over your own content, and automation pipelines. We engineer them the way production AI demands — grounded generation, fail-soft fallbacks so an AI outage never breaks your product, and cost control through caching and rate limits.
What engagement models does DevNest offer?
We work in flexible models to match your stage and in-house capacity: cross-functional teams that own the full product direction, augmented projects where our engineers join and extend your existing team, or a custom arrangement shaped together after a short conversation.
Which industries does DevNest work in?
Our clients span fintech, e-commerce, fashion retail, education, HR technology, email marketing, and domain registries — including iPost, CV-Library, River Island, and CentralNic. We pair deep technical skill with genuine understanding of each domain.
Where is DevNest based?
DevNest was founded in Cluj-Napoca, Romania in 2019, with additional offices in Flower Mound, Texas and Stockholm, Sweden. We are a locally built company that delivers internationally to a global client portfolio.
What technologies does DevNest use?
Our stack is deliberately eclectic — React with modern JavaScript and TypeScript on the front end; Node, Perl, and PHP on the back end; MySQL, AWS, and Redis for data and infrastructure; and full CI/CD DevOps pipelines. We choose the right tool for each product.
How do I start a project with DevNest?
Tell us about your project through the contact form or email hello@devnest.ro. We respond within one business day to discuss scope, approach, and the engagement model that fits best — there is no cost to start the conversation.
