Do you work with clients in Boston, United States?

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

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

For United States clients: websites typically $2,500 to $40,000. Mobile apps range $12k to $180k depending on complexity. SaaS MVPs start at $20k+. All quotes are W-9 / W-8BEN available 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 Boston clients?

We run a rolling overlap window that works for United States 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.

What United States Clients Say

Real Founders. Real Shipped Work.

Selected feedback from clients in United States — reviewed, referenceable, and used with permission.

“Worked with three US agencies before Zusta. None shipped. Zusta did — production-grade, W-9 compliant, and with eastern-timezone overlap every day. Our Stripe integration is rock solid.”

Jason M.

Founder, Fintech Startup (New York)

Mar 2026

“Our AI-powered support bot handles 61% of Tier-1 tickets now. Zusta built the entire RAG pipeline with Anthropic Claude and the eval harness that lets us catch regressions before rollout.”

Priya R.

Product Lead (San Francisco)

Jan 2026

“Engineering quality at US-agency level, at US-freelancer pricing. The architecture doc they delivered before coding started paid for itself three times over.”
