Do you work with clients in Kolkata, India?

Yes — we regularly work with founders, startups, and businesses based in Kolkata. Our HQ is in Kolkata, India, but we operate remote-first with working-hour overlap for India clients and on-site availability for major milestones.

How much does it cost to build a website, app, or SaaS from Kolkata?

For India clients: websites typically ₹40,000 to ₹8,00,000. Mobile apps range ₹3L to ₹30L depending on complexity. SaaS MVPs start at ₹6L+. All quotes are GST-compliant and include full source code ownership.

Which tech stack do you use?

We pick the right stack per project: React / Next.js / Vue for web, Swift / Kotlin / React Native / Flutter for mobile, Node.js / Laravel / Django / FastAPI for backend, PostgreSQL / MySQL / MongoDB / Supabase for data, and Claude / GPT-4 / LangChain for AI.

How do you handle time zones and meetings with Kolkata clients?

We run a rolling overlap window that works for India business hours. Standups are scheduled in your timezone, async-first updates via Slack/Linear/Notion, and live working sessions booked around your calendar.

Do I own the source code and IP?

Yes. Every engagement comes with a signed MSA that transfers full IP and source code ownership to you on delivery. Code ships to your GitHub / GitLab / Bitbucket org; infra and domains stay under your accounts.

“Rebuilt our storefront on headless Shopify + Next.js. LCP went from 4.1s to 1.3s. Sales up 22% in the first 60 days. They explain tradeoffs like partners, not vendors.”

“Zusta's engineers wrote cleaner Laravel than our in-house team. Replaced our legacy ERP in 90 days with zero downtime migration. Would hire again in a heartbeat.”
