What We Build For Chennai Teams
As a custom software development company serving Chennai, we ship full-lifecycle builds, from a single-team MVP to a multi-pod enterprise platform. Start with the layer your stage needs today and bolt on the rest as the product grows.
Bespoke web and back-end systems built to your business logic.
Domain modelingAPI-first designTypeScript and GoRBI and DPDP ready
Bespoke web and back-end systems built around your business logic and data model, delivered through our custom application development services. No template, no configured SaaS, real software engineered for your scale target and the compliance bar Chennai's automotive and manufacturing supply chains already run to.
Multi-tenant SaaS with billing, roles, and analytics from day one.
Multi-tenantStripe readyUsage analyticsRole-based access
Multi-tenant SaaS builds with billing, role-based access, and analytics from day one, the same practice behind our work as a SaaS development company. Built for the B2B and vertical SaaS founders clustering along Chennai's Old Mahabalipuram Road tech belt, most of them heading toward a Series A.
Native and cross-platform apps for Chennai's customers and field teams.
iOS and AndroidFlutter and RNOffline modeApp Store ready
Native iOS and Android or cross-platform builds with Flutter and React Native, delivered by our mobile app development company practice. Offline mode and a release cadence built for field teams working Chennai's auto-manufacturing and logistics floor, not just customer-facing apps.
LLM features and ML scoring shipped with evals and guardrails.
LLM and RAGEvals and guardrailsCost-boundedObservability built in
LLM-powered features, RAG pipelines, and ML scoring embedded into the products you ship, with evals, guardrails, and a clear cost ceiling. Treated as engineering from the first sprint, not a proof of concept that never reaches production.
You do not need every layer on day one. Tell us where you are, we will tell you where to start.
A four-phase delivery model that ships production software on a real timeline. Senior engineers, weekly demos, and a working build you can see, not a Gantt chart in a status doc.
Book a Call{ 01 }· 1 to 2 weeks
We map your goals, constraints, integrations, and compliance needs. By the end you hold a reference architecture, a scoped backlog, and a timeline you can actually plan around.
{ 02 }· 2-week sprints
UX flows, API contracts, and the core build in agile sprints with a working demo every two weeks. CI/CD and code review wired in from the first commit.
{ 03 }· Before go-live
On production-equivalent infrastructure, we run penetration tests, load tests, and a full security review. Go-live waits until every item on the checklist is green.
{ 04 }· Launch onward
A staged rollout, real-time observability, and on-call handover. We tune, ship features, and back the system with an SLA you can plan against.

Questions Answered
Zethic partners with Chennai businesses as a custom software development company. A senior pod runs your build end to end, joins you for kickoffs, architecture reviews, and key milestones, and keeps a working demo in front of you every two weeks. The same senior-pod model runs at our custom software development company in Hyderabad, for teams building out of Telangana.
It means designing and building software around how your business actually operates, rather than adapting your workflow to fit an off-the-shelf product. That covers the architecture, the codebase, the integrations, and the data model.
Scope, the integrations involved, and your compliance requirements set the number. A focused MVP is usually a fraction of a full enterprise platform. After a scoping call we share an honest cost band broken into milestones you can stop at.
A focused MVP typically takes 12 to 16 weeks. A full enterprise platform with multiple roles, complex workflows, and a mobile app usually runs 6 to 12 months, with a working build every two weeks along the way.
You do, fully. Code lives in your repository, the cloud account is in your name, and the IP belongs to you. There are no license fees after handover and no lock-in to any proprietary runtime.
