Zesxai

Zesxai is an AI-first software development company building intelligent, scalable products for startups, SMBs, and enterprises, from fast MVPs to large-scale ERP platforms.

Backed by 7+ years of engineering experience, our team of 2 to 50 developers, designers, and AI specialists works as a true extension of your business. Unlike agencies that assign one or two developers, every Zesxai client gets access to our full team, which means faster delivery, broader expertise, and consistent quality.

Our Services:

• AI Development: Custom AI agents, agentic workflows, LLM-powered features (OpenAI, Claude), voice AI, intelligent chatbots, and end-to-end business automation
• Web Development: High-performance web apps and SaaS platforms using React, Next.js, TypeScript, and modern cloud stacks
• Custom Software Development: Tailored software solutions designed around your workflows, from internal tools to customer-facing products
• ERP Solutions: Scalable ERP, HR, payroll, finance, and inventory systems built for growing organizations
• Mobile App Development: Cross-platform iOS and Android apps with clean UX and reliable performance
• Generative AI: AI content generation, document intelligence, knowledge base assistants, and RAG-based solutions

What Sets Us Apart:

• AI built into the core of every product, not added later
• 20+ satisfied clients across Europe, the US, and beyond
• Complete delivery cycle: discovery, UI/UX, development, deployment, and long-term support
• Flexible models, from fixed-scope projects to dedicated monthly teams
• Transparent communication with working hours aligned to European and US time zones

From AI-powered SaaS products to enterprise-grade ERP systems, Zesxai helps ambitious businesses turn ideas into software that performs, scales, and grows with them.
