Build custom software
Bespoke platforms and AI features engineered around your workflows. Fixed-scope or dedicated-team engagement, with clean code you fully own.
Custom Software βZetsApp is a software development and SaaS studio for startups, scale-ups, and enterprises. We build custom software, deliver AI and RAG systems, and publish ready-to-adopt SaaS products across HR, CRM, healthcare, education, construction, and finance. One partner, three ways to move faster: build custom, buy a product, or blend both.
We are a full-cycle engineering partner. Discovery, architecture, UX design, front-end and back-end development, QA, DevOps, and ongoing support all sit in one accountable team β so features move from spec to production without weeks lost to vendor hand-offs. Our engineers cover full-stack web (React, Angular, .NET, Node.js, Django, Rails), cross-platform mobile (Flutter, React Native), production AI and RAG (LangChain, LlamaIndex, on-prem LLMs, vector databases), and cloud DevOps on AWS, Azure, and GCP.

UX and architecture done in parallel so build risk surfaces early. Prototypes are click-through in weeks, not months.
Two-week sprints, working software every sprint, and demos your stakeholders actually see running. Typed, tested, documented code.
CI/CD, infrastructure-as-code, monitoring, and staged rollout so launches are routine events, not scheduled emergencies.
Post-launch maintenance, optimisation, and new-feature development on a predictable monthly retainer where you want it.
ZetsApp delivers across three primary markets, each with local compliance, hiring, and delivery details:
Our engineers build with GDPR, HIPAA, and SOC 2 controls in mind from day one β encryption in transit and at rest, role-based access, audit logging, DPIA-ready architectures, and BAA-friendly third-party choices. On-prem and EU/UK/US-region deployment options let regulated buyers keep sensitive data inside their perimeter, including for AI and RAG workloads.
