- What kind of software does Sionex build?
- We build custom websites, web platforms, cross-platform mobile apps, CRMs, ERP-style operational software, AI chatbots and AI agents — plus UI/UX design, maintenance retainers and short discovery sprints. Anything from a marketing site to a multi-module internal platform.
- Where is Sionex located, and do you work with clients outside Hosur?
- Sionex is based in Hosur, Tamil Nadu — about 40 km from Bangalore. We work with clients across India and run projects remotely with regular video calls, weekly demos, and a shared progress dashboard.
- How much does a typical project cost?
- Costs depend on scope, but a simple marketing site usually starts in the low lakhs, mobile apps and CRMs in the mid-lakhs range, and full ERP or AI platforms scale from there. We give a fixed quote after a free discovery call.
- How long does a project take?
- Marketing websites typically launch in 2–4 weeks, mobile apps and small CRMs in 6–10 weeks, and larger ERP or AI platforms in 3–6 months — with weekly demos throughout so you see progress as it happens.
- Do you offer support after launch?
- Yes. We offer monthly support and maintenance retainers covering monitoring, bug fixes, small feature additions and security updates. Most clients stay on long-term as their software evolves.
- Which technologies do you use?
- For web we use Next.js, React, Node.js and TypeScript. For mobile, React Native (and Flutter for select projects). For AI, leading providers like Anthropic Claude and OpenAI through proven frameworks such as the Vercel AI SDK. We host on Vercel and Supabase, and bring in AWS or Google Cloud when the project genuinely needs it — we won't over-engineer your infra.
- Can you integrate AI into our existing software?
- Absolutely. We routinely add AI chatbots, document understanding, smart search, and AI agents into existing CRMs, ERPs and customer portals — without rebuilding everything from scratch.
- How do we get started?
- Call +91 80504 02243, email sionexlabs@gmail.com, or use the enquiry form on this page. We'll schedule a free 30-minute discovery call to understand your needs and share a clear plan and quote.
