Software Development Agency
A Mumbai software development agency for founders who want one studio that ships brand, web, mobile, and AI — not four vendors duct-taped together.
Software development at Sitio Labs is full-stack and full-discipline. Mati handles brand, design, and editorial polish. Zerocode ships the native iOS and Android. The shared engineering practice builds the web app, the backend, the AI layer, and the deployment pipeline. One studio, one point of view, one Slack channel — instead of four agencies who blame each other when something breaks.
What kind of software development agency Sitio Labs is
Most software development agencies specialise narrowly — a brand agency, a mobile agency, a backend shop, an AI consultancy. The integration tax of working with four of them is enormous: every handoff loses information, every meeting is a vote between vendors who do not trust each other. Sitio Labs is structured against that. The Mati practice and the Zerocode practice operate under one roof, with one founder leading direction, and the same engineers who build your backend also work alongside the designers who shape your brand. You hire one software development agency and you get the full stack.
What we ship as a software development agency
Web applications in Next.js and TypeScript with server components by default, type-safe from the database to the UI. Native mobile in Swift and Kotlin via the Zerocode platform. Backend services in Node, Postgres, Redis. AI integrations using Anthropic, OpenAI, or self-hosted models depending on the constraint set. CI/CD pipelines, infrastructure-as-code, observability, on-call runbooks. The full stack of a software product, designed and engineered by one studio. We work for founders who want to launch and scale, not founders who want to manage an agency portfolio.
How we run software development engagements
Engagements run on a four-chapter cadence: Discovery, Direction, Build, Ship. Discovery is a 90-minute call plus a 1-week brief. Direction is design, architecture, and the technical SOW. Build is the development phase, weekly Thursday reviews, no theatre. Ship is the launch — App Store, Play Store, production deploy, monitoring, the runbook handed to your team. Each chapter has a fixed deliverable and a fixed cost percentage. There are no hourly bills. There are no offshore subcontractors. There are no surprise change orders that did not exist in the SOW.
When to hire a software development agency vs in-house
Hire an agency when: speed matters more than headcount, you want a full-stack product launched in weeks rather than the year-plus it takes to build a 10-person team, or you are pre-Series A and a fixed-fee external partner is more capital-efficient than full-time hires. Hire in-house when: you have a product-led organisation that needs continuous iteration, you have the runway to wait for hires, or your domain is so specific that a generalist agency cannot ramp up. We will tell you in discovery which side you are on. The right answer for some clients is “hire two senior engineers, not us.”

What kinds of software does your development agency build?
Web applications, native iOS and Android apps, AI-integrated products, internal tools, marketing-grade websites, and the backend services that connect them. Brand and UI/UX design come from the same studio.
How much does a software development engagement cost?
From ₹12,00,000 for a Studio-tier engagement (6–10 weeks, full stack). Sprint-tier is from ₹3,00,000 for a single artifact in 2–3 weeks. Long-form Partner retainers are ₹6,00,000 / month with an embedded squad.
Do you only work with Indian founders, or globally?
We work with founders globally. Quoted in INR, USD, GBP, or AED depending on the client. Most engagements run on Indian Standard Time with weekly Thursday reviews; we have the timezone overlap to support founders in the US (PST mornings) and Europe (BST afternoons).
What is your tech stack?
TypeScript, Next.js, Node, Postgres, Sanity for content, Cloudflare and Vercel for hosting, Swift and Kotlin via Zerocode for mobile, Anthropic and OpenAI for AI. We can adopt your existing stack if there is a strong reason — but we will push back if the stack is fighting the goal.
Do you offer ongoing maintenance after launch?
Yes. Standard engagements include 30 days of post-launch support. After that, we offer a Partner-tier retainer (12 hours / week from an embedded squad) for teams that need continuous iteration without hiring an in-house engineering team.
