Frequently Asked Questions

Zulbera is a premium, senior-only software development studio that builds custom SaaS platforms, enterprise web applications, mobile apps, and AI-powered products for funded founders and growth-stage companies. Founded in 2020, the studio operates as a hybrid distributed team across Hong Kong and Europe. Zulbera takes full ownership of architecture, development, and delivery — it is not a staff-augmentation agency and does not place developers by the hour.

Zulbera was founded in 2020 by Jahja Nur Zulbeari, a technical architect with over 10 years building custom SaaS platforms and enterprise web applications for European and US clients. He specialises in API-first architecture, multi-tenant SaaS, and compliance-heavy verticals such as FinTech and HealthTech.

Zulbera is deliberately small and senior-only. Every engineer assigned to a build is a senior practitioner — there are no junior developers billed at senior rates and no hand-offs to an unseen offshore bench. The studio has delivered 120+ projects and holds an aggregate rating of 4.9 out of 5 across 20 verified reviews.

Engagements start at a €20,000 minimum. A typical project ranges from €25,000 to €500,000+ depending on scope, with most custom SaaS builds landing between €30,000 and €150,000. Pricing is fixed-scope per phase rather than hourly, so you know the cost before production begins.

After a 2–3 week paid discovery sprint, most builds run 10–24 weeks in sprint-based phases with weekly demos and a staging environment. A focused SaaS MVP can ship in roughly 10–14 weeks; larger enterprise platforms take longer. Timelines are agreed during discovery before any production commitment.

Four stages: (1) a paid discovery sprint to lock architecture, scope, and team match; (2) a build phase of 10–24 weeks with weekly demos, staging, and continuous deployment; (3) launch and handover including load testing, a security audit, production cutover, monitoring, and documentation; and (4) an optional ongoing partnership retainer for new features and infrastructure.

You do. On handover the client owns 100% of the source code, infrastructure, and intellectual property — including repositories, documentation, and deployment configuration. There is no vendor lock-in and no licensing of the core product back to you.

Yes. Zulbera takes on greenfield builds as well as existing products that need to be extended, re-architected, or rescued. The studio can operate as the full product team or integrate with an in-house team, owning specific systems end to end.

The core stack includes React, Next.js, Astro, Node.js, TypeScript, Flutter and React Native for mobile, PostgreSQL and Supabase, Stripe Connect for billing, and the OpenAI and Anthropic Claude APIs for AI features — deployed on AWS with Docker and GitHub Actions. Technology choices are made per project, not forced from a template.

Zulbera builds LLM integrations, RAG architectures, AI workflow automation, and intelligent data pipelines using the OpenAI and Anthropic Claude APIs. AI is treated as an architectural decision — the studio scopes where AI genuinely creates leverage rather than bolting it on for marketing.

Zulbera works primarily with clients in the United Kingdom, the DACH region (Germany, Austria, Switzerland), the Netherlands, North America, the UAE, and Asia-Pacific. With team coverage across UTC+8 (Hong Kong) and UTC+1 (Europe), there is broad working-hours overlap with the UK, DACH, and Asia-Pacific.

Yes. Zulbera builds GDPR-compliant architecture with EU data residency available (Frankfurt, Dublin). The studio has hands-on experience with FCA, PSD2 and SCA for UK and EU fintech; BaFin and VAIT for German financial services; nFADP and Swissmedic alignment for Swiss healthtech; and SOC 2 Type II readiness on request.
