What YipYip does

YipYip is a full-service mobile application and web development studio headquartered in Rotterdam, Netherlands, operating since 2009 with a team of more than 15 professionals. The company designs and builds native iOS applications using Swift (covering iPhone, iPad, Apple Watch, Apple TV), native Android applications using Kotlin, cross-platform apps via Flutter, and backend services on the Elixir/Phoenix stack, with frontend delivery in HTML5, CSS3, and JavaScript and hosting across Google Cloud Platform, AWS, and Microsoft Azure. Its offering combines in-house UX/UI design (wireframing, design systems, Figma prototyping, WCAG-aligned accessibility) with engineering under one roof, supplemented by a Design Sprint methodology that takes clients from idea to prototype in 1–2 weeks. Core product examples include the ROOS24 Flutter loyalty platform for Smart City Roosendaal, the Afasietherapie online speech therapy platform with embedded speech recognition, the Stadswandeling Amsterdam audio-tour web app with Mapbox integration, the Kinderdijk UNESCO walking-tour app, and the Watertaxi Rotterdam responsive website and internal Schippers iPad app.

YipYip serves four customer segments: commercial companies as the primary segment, Dutch government organizations, healthcare providers, and startups. Logo evidence spans Heineken (beverage), Watertaxi Rotterdam, Gemeente Rotterdam and Smart City Roosendaal (government), Kinderdijk (tourism/government), Stichting KiKa and NV Zeedijk (cultural/nonprofit), NSDSK and Logoclicks (healthcare), and startups such as RunaR (ISS Detector), Movely, and PersonHelp. The company holds ISO/IEC 27001:2017 and NEN 7510-1:2017 certifications, the latter specifically gating Dutch healthcare procurement, and aligns service messaging with the European Accessibility Act effective July 2025. Industry validation includes consecutive Emerce100 Best App Developers Netherlands rankings in 2024 and 2025 and a Dutch Game Award for Best Serious Game.

Revenue is generated primarily through custom project-based app development engagements starting at approximately €20,000 excluding VAT, with standard projects running 2–4 months and larger projects 12–16 months. The company supplements one-time build revenue with recurring Service Level Agreement (SLA) maintenance and first-line support contracts, including optional 24/7 availability. Go-to-market is sales-led, operating through direct outreach, a curated portfolio showcase, and selective participation in competitive pitches where the team screens on number of competing parties, pitch fees, and transparency of selection criteria. Pricing varies with target platforms (native being the most expensive, followed by Flutter), CMS requirements, push notifications, payment integration, and login/authentication scope. YipYip is privately held under Dutch Besloten Vennootschap (B.V.) law with no disclosed venture funding, acquisitions, or parent-company relationship.
