Zulbera

Zulbera is a senior-only nearshore software development studio building custom SaaS platforms, enterprise web applications, and AI-integrated products for founders and CTOs across Europe and North America.

We specialize in API-first architecture, multi-tenant SaaS, and compliance-heavy verticals — FinTech, HealthTech, GovTech, and B2B Enterprise. Every engagement begins with a paid 2-3 week discovery sprint producing technical specifications, architecture decision records, and a realistic timeline before any production commitment.

Our engineering team is senior-only. No junior rotation, no offshoring, no bait-and-switch. The engineers named in our proposals are the engineers who write the code. We operate with CET timezone coverage and full overlap with UK, DACH, Netherlands, and Nordics — with 4-hour overlap with US East Coast working hours.

Technical depth: React, Next.js, Node.js, TypeScript, Python, PostgreSQL, AWS, GCP. We build production-grade multi-tenant SaaS with row-level security, real-time WebSocket infrastructure, async job processing, and full GDPR/CCPA/SOC 2-ready compliance architecture from day one.

Industries: SaaS (B2B and B2C), FinTech, HealthTech, PropTech, LegalTech, InsurTech, marketplace platforms, AI-native products. We serve founders building their first MVP through Series B platforms requiring scale architecture and compliance audits.

Engagements start at $25,000 for focused MVP scopes and scale to $500,000+ for enterprise platforms. We work on Time and Materials with monthly invoicing, transitioning to dedicated team structure for long-term partnerships.

What sets us apart: senior-only team stability, documented architecture decisions as standard practice, transparent process with weekly demos, source code ownership from day one, and a 70%+ client re-engagement rate.
