Work
View all projects→A process built
around shipping.
Four phases. Twelve weeks on average. No deck-ware, no kickoff theatre — just weekly demos from the week you sign.
Discovery
Workshops, stakeholder interviews and a hard look at what exists. You leave with a prioritized scope, a risk register, and a north-star you can defend to the board.
Design
Hi-fi flows, a living design system, and prototypes that click. We design in-browser when we can — so what you approve is what you ship.
Build
Weekly demos. Shared staging from day one. CI, tests and docs aren't a "later" — they're how we keep velocity high into month three and beyond.
Launch & Scale
We don't drop and run. Observability, on-call, a 30/60/90 roadmap and a handover your team can actually pick up — or a long-term retainer if you want us in the trenches.

Launch Runbooks
Deployment notes, QA checklists, training docs, and support plans so the team can own the system.
Zethius Studio is a software and web development agency based in Ghaziabad (Delhi NCR), India, that builds custom CRM, ERP, dashboards and websites, and runs SEO, Meta ads and WhatsApp lead generation for businesses in India and worldwide.
Both. We design and develop business websites on Next.js, and we build custom software — CRM, ERP, dashboards and internal tools — so your website, lead flow and operations run on one connected system instead of disconnected tools.
We are based in Ghaziabad, Uttar Pradesh, and work with clients across Delhi NCR (Noida, Delhi, Gurugram), the rest of India, and internationally. Projects run remotely with scheduled calls, shared boards and weekly demos.
Every project is quoted after a scoping call, because cost depends on the number of workflows, integrations, data migration and users — not on a template. You get a written scope, timeline and quote before any work starts.
A landing page takes 2–3 weeks and a full business website 4–7 weeks. A starter CRM takes 4–6 weeks, a foundation ERP 6–8 weeks, and larger multi-module systems are rolled out in phases over 3–6 months.
Use an off-the-shelf CRM if your sales process is standard and your team is small. Build custom when you pay for many seats you barely use, your process does not fit the default pipeline, or you need deep WhatsApp, ERP or accounting integration.
Yes. You own the full codebase, database, documentation and deployment setup. There are no per-seat licence fees, and you can host it on your own cloud account.
Yes. We run technical SEO, Meta (Facebook and Instagram) ads and WhatsApp lead generation, and connect every lead source to your CRM so you can see which channel actually produces revenue.
