What We Offer
We build full-stack SaaS products from architecture through deployment, with a specific focus on products that need to scale across Dutch and broader European markets. Here’s what working with us actually looks like in practice:- SaaS MVP Development (Fixed-Price, 8 Weeks): We scope, architect, and ship a production-ready MVP — multi-tenant backend, authentication, billing integration, and a clean Next.js frontend. You get a deployable product, not a prototype.
- API-First Backend Architecture: Every product we build uses Python FastAPI for the core backend. That means typed, documented, testable endpoints from day one — essential when you’re planning integrations with Dutch payment providers like Mollie or Buckaroo, or connecting to EU-hosted enterprise systems.
- Multi-Tenant SaaS Infrastructure: We design tenant isolation, role-based access control, and data segregation properly at the schema level — not bolted on afterward. This matters especially for Dutch B2B SaaS products serving SMEs or enterprise clients under GDPR constraints.
- Ongoing Development & Feature Sprints: Beyond the MVP, we offer structured sprint-based development for teams that need a reliable technical partner to keep building. You get predictable velocity, no surprise invoices, and a founder who’s personally accountable for every commit.
Why Choose Zargham Labs
There are Dutch development agencies, freelancers on Upwork, and large nearshore firms all competing for the same SaaS projects. Here’s the honest case for working with us instead:- US-Registered, Pakistan-Based Pricing: Zargham Labs LLC is incorporated in the United States, which means clean contracts, wire transfers, and professional accountability. But our team operates from Pakistan, which keeps our rates 40–60% below what you’d pay a comparable Amsterdam or Rotterdam agency — without compromising the quality of the output.
- Founder on Every Project: Zargham personally handles architecture, code review, and client communication on every engagement. You’re not handed to a junior team after the sales call. There’s no account manager layer between you and the person actually building your product.
- Messenjo Is Live Proof: Our flagship product, Messenjo (messenjo.io), is a production WhatsApp Business automation platform built on the exact stack we’d use for your SaaS. It runs FastAPI, Next.js 14, PostgreSQL with PgBouncer, Celery, Redis, and Docker behind Traefik. We don’t just describe this architecture — we operate it daily.
- No Bloated Agency Overhead: We run lean on purpose. No project managers justifying their existence, no mandatory design sprints that eat three weeks before a line of code is written. We move fast because our structure allows it.
Our Tech Stack
For SaaS products targeting the Dutch and broader European market, this is the stack we use and why each component earns its place:- Python FastAPI: High-performance async backend that generates OpenAPI documentation automatically. Critical for SaaS products that will expose APIs to third-party integrations or enterprise clients — common in Dutch B2B contexts.
- Next.js 14: Server-side rendering, App Router, and strong TypeScript support make it the right choice for SaaS dashboards that need fast load times, SEO, and a maintainable frontend codebase.
- PostgreSQL + PgBouncer: Relational data handled correctly, with connection pooling that keeps the database performant under multi-tenant load. GDPR-compliant data architecture is straightforward to implement with proper schema design here.
- Celery + Redis: Asynchronous task queues for background jobs — email notifications, report generation, scheduled data syncs — things every production SaaS needs and that should never block the main request cycle.
- Docker + Traefik: Containerized deployments with automatic SSL and reverse proxy routing. Deployable to any EU-region cloud provider — AWS Frankfurt, DigitalOcean Amsterdam, or Hetzner — keeping your data residency within European borders.
- n8n: Workflow automation layer for SaaS products that need to connect to CRMs, ERPs, or third-party Dutch business tools without custom integration code for every connector.
Our Process
Every SaaS engagement follows a structured eight-week delivery model. Here’s how it maps to your project specifically:- Week 1–2 — Discovery & Architecture: We map your core user journeys, define the data model, and produce a technical architecture document. For Dutch market SaaS products, this includes GDPR data flow documentation, tenant isolation strategy, and a confirmed list of third-party integrations — payment providers, accounting tools like Exact Online or Twinfield, and any EU-hosted APIs your product depends on.
- Week 3–4 — Core Development: Backend API endpoints built and tested, authentication and authorization implemented, database schema deployed to staging. By the end of week four you have a working system you can log into — not a design mockup.
- Week 5–6 — Integrations & Testing: Frontend connected to the API, third-party integrations wired in, automated test coverage added for critical paths. We run load testing to confirm the multi-tenant architecture holds under realistic user volumes.
- Week 7–8 — Deployment & Handover: Production environment configured on your chosen EU-region cloud infrastructure, monitoring and alerting set up, CI/CD pipeline live. You receive full documentation, source code ownership, and a recorded walkthrough of the entire system.
Frequently Asked Questions
Can you build a SaaS product that complies with GDPR requirements for the Dutch and EU market?Yes — GDPR compliance is a core part of how we architect SaaS products, not an afterthought. We implement proper data residency (EU-region hosting), tenant data isolation at the database level, consent management hooks, and data deletion workflows from the start. We can also produce the data flow documentation your legal team will need. What does a fixed-price SaaS MVP actually cost, and what’s included?
Our fixed-price MVPs start at $8,000–$15,000 USD depending on scope and integration complexity. That covers backend API, frontend dashboard, authentication, one payment integration, staging and production deployment, and full handover documentation. We define the scope precisely in week one so there are no invoice surprises at delivery. Do you have experience with Dutch-specific integrations like Mollie, Exact Online, or iDEAL payments?
We’ve worked with Mollie’s API for subscription billing and one-time payments, and we’re familiar with the OAuth flows required by Dutch accounting platforms. If your product requires a specific integration we haven’t built before, we’ll tell you upfront — and we’ll scope the research and build time into the project properly rather than discovering it mid-sprint.
