ZetsApp is a custom software development company for US-market companies. We build HIPAA-aware, SOC 2-ready custom software, AI, RAG, and full-stack platforms — with US business-hour overlap, standard MSA/SOW paperwork, W-9 supplier status, and USD invoicing.
US buyers choose engineering on outcome, quality, and communication — not just rate. Our developers ship in fluent English, keep US-hour stand-ups, run US-style sprints and demos, and produce the documentation and test coverage a US CTO expects to inherit. We handle onboarding, off-boarding, and the paperwork so your team focuses on outcomes.
Whether you are shipping a healthcare product under HIPAA, a fintech tool preparing for SOC 2, or an enterprise integration under strict change control, our engineers build with those constraints in mind — audit-friendly logging, encryption at rest and in transit, role-based access, backup and DR, incident response — and produce the artifacts your auditor will ask for.
Hire dedicated engineers on flexible monthly terms, augment your US team for a sprint, or engage on fixed scope. You interview and choose the engineers; we handle contracts, payroll, and management. USD invoicing, W-9 supplier status, standard MSA/SOW, and BAAs where HIPAA applies.
EHR/EMR integrations, telehealth, patient portals with HIPAA-grade audit and encryption. BAA-ready.
Ledgering, payment integrations, and change-management controls that pass SOC 2 Type II audit.
Grounded AI over enterprise knowledge with evaluation, guardrails, and cost control.
US-region infrastructure, IaC with Terraform, Kubernetes where warranted, cost-optimised autoscaling.
React Native and Flutter for one codebase; App Store and Play submission handled.
Same team from first shippable MVP to a platform serving millions of US users.
