5(10 reviews)Technology partner for companies seeking excellence
RecommendedTop awarded🔥 Your ERP isn't performing. Your website isn't converting. Your data isn't talking to each other. Your team lives in Excel. And the big consulting firms offer you a €80,000 diagnosis and a beautiful PowerPoint. 📊 Databay Solutions does the opposite: we deliver working systems, websites that sell, and digital products that make a difference. We are an Odoo Silver Partner with 5 offices in Spain —Málaga, Córdoba, Almería, Cádiz, and Valencia— and a team that combines what almost no one else does: ✅ Odoo Enterprise: CRM, ERP, accounting, manufacturing, e-commerce, HR, VeriFactu. ✅ Websites, e-commerce, and custom software in React and Node.js. Real UX and design, not recycled templates. ✅ Data engineering, BI, and advanced analytics: data warehouses, executive dashboards, ETL, and data governance. ✅ AI in its two forms: agent-based with Claude (back-office automation) and classic (ML, scoring, prediction, computer vision). ✅ Industrial IoT: sensorization, plant data capture, and real-time platforms for the connected factory. ✅ Fractional CTO/CDO at the highest level, without the cost of a full-time C-level. 🚀 We don't just implement. We lead innovation with our own products: Inprove — IoT platform for predictive maintenance and industrial energy optimization. AI voice and WhatsApp phone system — Assistant that answers, qualifies, and resolves 24/7. ⚡ The big difference: a working prototype in the first few weeks. If you don't see value from the first milestone, there's no second invoice. It's that simple. 📈 We work with groups that generate between €5 and €100 million in revenue. Based in Andalusia and the Levante region, with projects across Europe. 📲 Stuck transformation, poorly implemented Odoo, a website that doesn't sell, or a major technical decision on the table? 30 minutes can save you 6 months. The first call is free. 🖥️ https://databay.solutions/ ✉️ info@databay.solutions 📞 +34 606 21 91 11Looking for work in EthereumLocated in Benalmádena, Spain (+1)From €1,000 for EthereumWorked in Education (+17)Speaks English, German(+1)11-50 membersLeetSoft
