We also build what does not exist yet.
The engineers who run five products take on a small number of client projects each year. You get people who have shipped, supported and been woken up by their own software.
How we engage
Fixed scope. Fixed price. Weekly working builds.
10 kinds of work we say yes to.
- 01
Web platforms and SaaS
Multi-tenant products, portals and back-office systems that people use all day.
Most of what we build runs in a browser and has to work on a slow Android phone in a district town as well as a desktop in a head office. We design the data model first, then the screens, then the polish.
- Product and information architecture
- Role-based, multi-tenant applications
- Billing, subscriptions and licensing
- Admin panels and reporting
- 02
Mobile apps and PWAs
Native where it matters, progressive web apps where speed of release matters more.
We have shipped Android and iOS apps and we have shipped PWAs that install from a link. We will tell you honestly which one your users need, and it is often the cheaper one.
- Android and iOS apps
- Installable progressive web apps
- Offline-first data sync
- Push and WhatsApp notifications
- 03
AI products and agents
Voice agents, chat agents and retrieval systems that do a job, not a demo.
We built a multi-tenant voice-agent platform on Gemini Live where each tenant brings its own API key and phone number, gives the agent tools it can call, and uploads documents the agent can quote from. The same pieces — streaming speech, function calling, retrieval, a transcript you can audit — build an agent for your front desk, your collections team or your support queue.
- Voice agents with telephony (inbound and outbound)
- Chat and WhatsApp agents with human handover
- Retrieval over your own documents (RAG)
- Tool and function calling into your systems
- Transcripts, evaluation and cost per conversation
- 04
Business process automation
Deleting the retyping, the reconciliation and the copy-paste between two systems.
A technician types twenty numbers off an analyser slip. A shopkeeper enters the same order into the shop and the accounts. Someone schedules the same social post every morning. These are not software problems, they are jobs nobody should be doing, and each one is a few days of work to remove permanently.
- Document and form data extraction
- Scheduled jobs, queues and retry-safe pipelines
- Two-way sync between systems that do not talk
- Report generation and distribution
- Approval workflows with an audit trail
- 05
Application security and audit readiness
Source-level review of software you already run, then the patches.
We have taken our own hospital platform through a VAPT audit by a CERT-In empanelled auditor, and we have run full-source security reviews of other people's applications. A review reads the code, not just the responses: authentication, authorisation, tenant isolation, injection, file handling, secrets in the repository and the payment flow. You get findings ranked by severity, the patches for what we can fix, and a plain list of what only you can do, such as rotating a leaked key.
- Full-source review (authentication, authorisation, multi-tenancy)
- Injection, XSS, CSRF and file-upload testing
- Secrets, configuration and dependency audit
- Security headers, rate limiting and session hardening
- Remediation patches and a re-test pass
- DPDP Act readiness and VAPT preparation
- 06
WhatsApp and voice agents
Business logic on the app your customers already have open.
Healthixio's front desk runs from WhatsApp and a voice assistant books its appointments. We build the same for other businesses: the WhatsApp Cloud API, approved templates, the 24-hour window, bulk campaigns and AI replies that know when to hand over to a human.
- WhatsApp Cloud API integration
- Template design and approval
- Conversational booking and support flows
- Voice assistants for front-desk tasks
- 07
Integrations and compliance
ABDM, HL7 FHIR, ASTM, GST, payment gateways and the systems already in the building.
We have taken a product through NHA's ABDM milestones and connected lab analysers over HL7 and ASTM. Integration work is where most projects slip; we have done enough of it to give you a fixed scope.
- ABDM (ABHA, HFR, HPR) integration
- HL7 FHIR R4 and ASTM interfaces
- GST e-invoicing and payment gateways
- Legacy database and ERP connectors
- 08
AI features that earn their keep
Voice notes into discharge summaries, follow-up drafting, document extraction.
We add language models where they remove typing or reading, not where they add a chat box. Every AI feature we ship has a plain fallback and a log of what it did.
- Speech to structured records
- Summaries and drafting inside workflows
- Document and form extraction
- Evaluation and guardrails
- 09
Hosting, cloud and DevOps
The boring infrastructure that decides whether your software is up at nine at night.
We run our own products on our own servers, which means we have been woken up by our own monitoring and have opinions because of it. For clients we size the server, automate the deploy, set up backups that have been restored at least once, and put alerts on the things that actually page a human.
- Server provisioning, TLS and reverse proxy
- Zero-downtime deploys and rollback
- Backups with a tested restore
- Monitoring, alerting and uptime checks
- Cost review and right-sizing
- 10
Data migration and long-term support
Moving off the old system without losing a record, then staying around.
Every Healthixio and Pathixio customer came from somewhere: paper, Excel, a desktop program from 2009. We migrate, reconcile, train, and then run the system with you. Support is part of the product, not a ticket queue.
- Data mapping and reconciled migration
- Staff training and go-live support
- Hosting, backups and monitoring
- Annual maintenance with named contacts
Discover, define, build, run.
Four stages, each with something you can hold us to. No phase ends with a document nobody reads.
- 01
Discover
A week with your team, at your site if we can. We map the workflow as it actually happens and write down what is slow.
- 02
Define
A fixed scope, a fixed price and a schedule you can hold us to. Screens and data model agreed before code.
- 03
Build
Weekly working builds you can click through, not slide decks. Change is welcome; it is priced, not hidden.
- 04
Run
Migration, training and go-live. Then hosting, backups, monitoring and a named person who answers.
Things we can show you running.
- A hospital front desk that runs from WhatsApp
- Healthixio's WhatsApp agent books OPD appointments from a chat and turns a doctor's voice note into a discharge summary.
- ABDM certification, milestones 1 to 3
- ABHA creation, FHIR R4 record bundles as a Health Information Provider, and consented record fetch as a Health Information User.
- Lab analysers talking to software
- Bidirectional HL7 and ASTM interfaces for haematology and biochemistry machines in Pathixio.
- A WhatsApp inbox and campaign tool
- For a client: WhatsApp Cloud API inbox, spreadsheet campaigns, AI auto-reply with human handover, per-message cost tracking.
- An installable gym app without an app store
- Gymnixio ships as a progressive web app that installs on Android and iPhone from a link.
- Migrations from paper, Excel and 2009
- Every Healthixio and Pathixio customer came from somewhere. We map, migrate, reconcile and train.
- A multi-tenant voice agent platform
- Tenants build a Gemini Live agent, connect it to a phone number through Tata Smartflo, give it tools to call and documents to answer from.
- Security reviews that read the code
- Full-source reviews of Laravel and Next.js applications: authentication, authorisation, tenant isolation, injection, secrets and the payment flow, ranked by severity and patched.
- Automation that deleted a retyping job
- Middleware that listens to a haematology analyser, so twenty numbers per test stopped being typed off a printed slip.
ABHA creation inside Healthixio

The Healthixio hospital dashboard
Each of these is written up as a case study, with no invented percentages: see our work.
Most of the product work is on the product pages: Healthixio, Pathixio, Biznixio, Gymnixio, Tatva ERP.
Before the first call.
What kind of custom software does Kentron Technologies build?
Web platforms and SaaS products, mobile apps and PWAs, WhatsApp and voice agents, integrations such as ABDM, HL7 FHIR, ASTM and payment gateways, AI features inside workflows, and data migration from legacy systems. Most of our work is for healthcare, diagnostics, sales-led SMEs and service businesses in India.
How do you price a project?
After a short discovery we give a fixed scope, a fixed price and a schedule. Changes during the build are welcome and are priced as changes rather than absorbed and hidden. Long-term support is a separate annual agreement with named contacts.
Do you work with companies anywhere in India?
Yes. Our products run in more than 110 cities and most custom projects are delivered remotely, with site visits at discovery and go-live. We work with organisations across India.
Will you host and maintain what you build?
Yes. We host, back up and monitor systems we build, and we run them with you after go-live. If you prefer your own infrastructure, we hand over documented, deployable code.
Next step
Describe the thing that does not exist yet.
Two paragraphs are enough. We will reply with questions, then a date for discovery.
