Halcyon Mobile

What Halcyon Mobile does

Halcyon Mobile is a mobile app design and development studio founded in 2005 and headquartered in Cluj-Napoca, Romania, with a commercial office in New York City at 110 Wall Street. The company operates a professional services model, assembling tailor-made cross-functional teams of product/UX designers and iOS, Android, Flutter, ReactJS, and backend engineers for each client engagement. Service offerings span product consulting, branding, UX/UI design, prototyping, full-stack mobile and web development, IoT/BLE integration, and machine learning. Clients include startups and product companies across EdTech (EdPlace), PropTech/smart offices (Nooka Space), medical devices (eXciteOSA — iF Design Award 2020), logistics (Urbantz, Roadz), wellness (121 Tribe, rTribe, Vern), and lighting IoT (Airstar), with delivery to the US, UK, Switzerland, France, Ireland, and Australia. The legal entity, Halcyon Mobile SRL, is privately held with no disclosed external venture funding, ownership stake, or acquisition history.

The company's technology stack centers on native iOS/Android, cross-platform Flutter, ReactJS front-end, NestJS/NodeJS/TypeScript back-end with Prisma ORM, BLE/GATT protocols for IoT, and an in-house AI research division called HalcyonLabs led by co-founder Levente Szabo. HalcyonLabs develops proprietary AI/ML capabilities including on-device convolutional neural networks (a 400kB CNN running inference in 14–24ms for NeuralDraw), computational photography for NeuralCam, NLP-based transaction categorization for Dollarbird, a custom snoring detection algorithm on time-series audio for eXciteOSA, and server-driven UI for IoT hardware abstraction. In addition to client work, Halcyon ships its own consumer products — Dollarbird (100,000+ registered users, 10M+ transactions), NeuralCam (2M+ photos, 25,000 users in first month), NeuralDraw, Neural Notes, and Neural Cam Alarm — which serve as capability demonstrators and feed the data and learning loop back into the studio's service offering.

Revenue is generated primarily through bespoke professional services engagements priced via custom quotes based on team composition, scope, and duration; no public pricing exists. Distribution is sales-led via the company website ('Get your team' / 'Contact us' forms) supplemented by referrals, a Dribbble portfolio, blog content, and conference presence (Droidcon Berlin, Droidcon London, Edge Design Talks). Consumer products are distributed through iOS App Store and Google Play. The company is GDPR-compliant (policy effective May 2018), holds no patents, and has not disclosed partnerships, M&A activity, or institutional investment.
