Do you work with clients in Belfast, United Kingdom?

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

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

For United Kingdom clients: websites typically £2,000 to £32,000. Mobile apps range £10k to £150k depending on complexity. SaaS MVPs start at £16k+. All quotes are VAT reverse-charge where applicable 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 Belfast clients?

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