# DevNest — custom software, built from scratch > Grow. Build. Enjoy! Tailored web, mobile and AI solutions for ambitious teams. DevNest is a software company founded in 2019 in Cluj-Napoca, Romania, delivering internationally. We build custom products and systems to your specifications — starting from a blank page when that is what the job needs — and we build and integrate production AI. The short version of what we do: **we build with AI, and we build AI — with human judgement at the core.** ## What we build from scratch - **New products and platforms.** Web applications and the systems behind them, architected and built to your requirements rather than bent out of a template. Our developers cover any industry, niche or user type, and pair technical depth with genuine business understanding. - **Mobile apps.** Native iOS and Android, or React Native where a shared codebase serves the product better. - **Production AI systems.** Retrieval-augmented generation (RAG) answer engines with cited sources, semantic and vector search, embeddings pipelines, and LLM-powered automation — engineered to be trustworthy, not demoed. - **The infrastructure underneath.** CI/CD pipelines, containerised environments, cloud platforms and monitoring, so a new product can actually be operated on day one. - **Quality as part of the build.** Unit, integration and end-to-end coverage embedded through the delivery cycle, including evaluation of LLM-backed features where correctness is probabilistic. Our Agile, solution-focused approach and full-cycle software development — accelerated by AI in our own workflow — produce robust and highly scalable products. We are here from a project's early stages through to full ownership and independence. ## How we help **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 grounded, cited 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 turn an idea into a real product so you can focus on growing the business — including honest advice on where AI fits and where it does not. **Software Engineering.** Custom products and systems built to your requirements, from scratch, for web and mobile. We build with AI-assisted workflows every day: faster delivery, same bar. **DevOps.** End-to-end pipeline delivery for cloud platforms, automating the critical processes around deployment and maintainability so time to market shortens. **Software Testing.** Functional, reliable and secure products, with QA engineers embedded in every stage of delivery. ## Why teams choose DevNest - **Strategic thinkers.** We look beyond the immediate brief to the bigger picture — strategy, vision and innovation sit at the core of what we deliver. - **Ownership.** When we take on a project we treat it as our own. Creativity, an innovative approach, and an empowered team culture are how we work. - **AI-fluent.** Our engineers build with AI daily and have shipped production AI systems — technical depth paired with genuine business understanding. ## AI in production, not in theory We built Business111.com, a live answer engine for UK businesses: retrieval-augmented generation with inline citations, semantic vector search over an owned Elasticsearch index, and a fully owned AI content pipeline including Whisper transcription, AI narration and automated social video. Grounded answers, fail-soft design, controlled costs, no managed AI vendor in the middle.
