Bintime

(1 review)
Strategy that ships. Continuity that lasts.
Bintime is a Dutch-founded custom software development and IT consulting company for data- and object-heavy enterprises — manufacturing, distribution, logistics, energy, food & beverage, E-commerce&retail and other industries. We help businesses where SKUs, objects, and operational data outgrow off-the-shelf tools turn complex data into production-grade software, web and mobile applications, and AI agents that deliver measurable business outcomes — then stay to run them. Our services: - Custom software development and enterprise platform engineering - Web and mobile app development for high-volume, high-SKU systems - Data engineering, system integration, and PIM / e-commerce solutions - AI consulting and custom AI agent development — agentic automation on your existing stack, measured by outcomes, not demos - EU product-compliance automation, including end-to-end EPREL (European Product Registry for Energy Labelling) registration - Embedded senior engineering teams and dedicated development pods that ramp in week one Two routes to the result: we build custom where you need it, or extend our own data products — Gepard PIM and B-Hive — where they fit. One partner, either path. Why clients choose Bintime: - 20+ years with high-volume, high-SKU, data-intensive systems - 00+ engineers across Europe - ISO 27001 certified - 10+ year average client relationship — we own the outcome, not just the ticket Selected clients include Icecat, PriceSpider, Futurumshop, and Dustin. Headquartered in the Netherlands with delivery across Europe, Bintime pairs strategic advisory with hands-on engineering: we help you decide what to build, ship it, and evolve it over time. Unlike large consultancies, we actually build. Unlike AI-hype vendors, we deploy automation that works in production. If your growth is limited by messy operational data, delivery capacity, or EU compliance deadlines, Bintime is the long-term partner that turns those constraints into working systems.
