What OneOverZero does

OneOverZero AG is a Zurich-based custom software development and digital transformation consultancy founded in 2005. Operating as a Swiss Aktiengesellschaft with 11–50 employees headquartered at Mühlegasse 5 in Zurich, the firm designs and implements bespoke IT solutions for enterprise clients across at least ten verticals including banking, insurance, healthcare/pharmacy retail, transportation (rail), telecommunications, media/streaming, heavy equipment, robotics/automation, workforce management, and consumer electronics. Notable engagements include Switzerland's first mobile banking application (Credit Suisse), the world's first live TV mobile streaming application (Zattoo), Switzerland's first mobile credit card application (Cornèr Banca), a custom wireless ticket-printing setup for SBB train conductors, an eCommerce platform for TopPharm over-the-counter products, a guidance system for BlueBotics' mobile robot fleets, and a content production pipeline powering UPC live sports coverage.

The firm's technology stack is built around custom software engineering and integration rather than a proprietary product suite. Solutions span mobile applications, eCommerce platforms, content production pipelines, enterprise integration systems, corporate health management platforms, and robotics guidance systems, with technical differentiation centered on customizability, novel architecture for media workflows, integration/interoperability with partner systems, domain specialization, and ease of implementation. Core engineering capabilities include mobile development, wireless system integration, live streaming infrastructure, fleet/robotics integration, and digital commerce — evidenced by category-defining firsts in Swiss mobile banking and global live TV streaming.

OneOverZero operates a sales-led, project-based professional services model. Revenue is generated through bespoke software development engagements priced via quote rather than published pricing, with prospective clients reached through direct enterprise outreach ([email protected], +41 43 538 42 94) and the company's website. The firm serves enterprise customers exclusively, with a blue-chip roster that has historically included Credit Suisse, SBB, Swisscom, Zattoo, and Cornèr Banca, and has demonstrated international delivery capability by enabling Avesco Group's expansion into five nations. The company is privately held and bootstrapped — no funding rounds, M&A, or institutional investors are disclosed.
