Most SMEs pay for 8โ15 disconnected tools that don't share data. Zynthoro replaces all of them at a fraction of the cost. Unlike SAP or Oracle, it's built for small and mid-sized businesses โ affordable, self-serve, and AI-powered from the ground up. Unlike point solutions like HubSpot or Xero, it covers the entire business operation in one place.
Ambitious SMEs, solo founders, growing startups, and trade businesses across Europe who are currently running on a patchwork of disconnected tools and want one platform to run their entire operation.
Zynthoro was built solo by Ramona Vijfvinkel, founder of Casa Haya International BV, from concept to commercial launch โ no team, no office. It went live on June 30, 2026. Selected for Anthropic Claude for Startups and Microsoft for Startups. XPRIZE Build with Gemini nominee 2026.
