What We Offer
Our SaaS development work for Swiss clients covers the full product lifecycle — not just writing code, but architecting systems that can survive audit trails, multi-tenant data isolation requirements, and the kind of enterprise procurement scrutiny common in Zurich, Geneva, and Basel.- Custom SaaS Platform Development: We design and build multi-tenant SaaS applications from scratch using Python FastAPI on the backend and Next.js 14 on the frontend. You get a codebase you own outright — no proprietary lock-in, no mystery framework that only one developer understands.
- Data Residency Architecture: For Swiss clients dealing with nFADP or handling sensitive financial, healthcare, or legal data, we architect your database and infrastructure layer with data residency in mind from day one — not as a retrofit. PostgreSQL with PgBouncer for connection management, Docker containerization, and deployment configurations that can target EU or Swiss-region hosting providers.
- API-First Backend Systems: Every platform we build is API-first, which means your product can integrate with Swiss ERP systems, banking APIs, or third-party enterprise tooling without significant rework. FastAPI gives you automatic OpenAPI documentation your enterprise clients and integration partners can actually use.
- Workflow Automation Integration: Many Swiss SaaS products need to automate internal operations — onboarding flows, billing triggers, notification systems, reporting pipelines. We build these using Celery task queues, Redis, and n8n for no-code-friendly automation layers your operations team can manage without engineering support.
Why Choose Zargham Labs
There are Swiss software agencies that will charge you CHF 180–250 per hour for a team you’ll never fully know. There are offshore shops that will underbid and disappear after delivery. We sit in a different position entirely.- US-Registered, Cost-Competitive Pricing: Zargham Labs LLC is registered in the United States, which matters for contract certainty and professional accountability. Because our development team operates from Pakistan, our rates are 40–60% below what you’d pay a comparable Swiss or Western European agency — without any compromise on the technical level of work.
- Founder on Every Project: Zargham personally handles architecture, code review, and client communication on every engagement. You are not passed to a junior account manager after the sales call. The person you speak to is the person building your product.
- We’ve Shipped Our Own SaaS Product: Messenjo — our WhatsApp Business automation platform at messenjo.io — runs on the exact same stack we build for clients. FastAPI, Next.js, PostgreSQL, Celery, Redis, Docker, Traefik. It processes real production traffic. When we tell you this architecture works, we’re not theorizing.
- 8-Week MVPs That Are Actually Deployable: We don’t do six-month discovery phases. Our 8-week delivery model gets you a working, deployed MVP that real users can access — then we iterate from validated feedback rather than assumptions.
Our Tech Stack
Every technology choice we make is deliberate and suited to the demands of SaaS products targeting the Swiss market, where security, reliability, and maintainability are non-negotiable.- Python FastAPI: High-performance async backend framework with automatic OpenAPI spec generation. Ideal for SaaS products with complex business logic and third-party API dependencies — common in Swiss fintech, insurtech, and enterprise software.
- Next.js 14: React framework with server-side rendering, which delivers the fast load times and SEO performance that B2B SaaS products need for credibility in enterprise sales cycles.
- PostgreSQL + PgBouncer: Robust relational database with full support for row-level security and multi-tenant data isolation. PgBouncer manages connection pooling under load. Critical for any SaaS handling sensitive client data.
- Celery + Redis: Asynchronous task processing for background jobs — billing cycles, email triggers, scheduled reports, data exports. Redis also handles caching to keep your application responsive at scale.
- Docker + Traefik: Containerized deployment with automatic SSL, reverse proxying, and environment portability. You can deploy to any cloud provider — including EU/Swiss-region infrastructure — without re-engineering your setup.
- n8n: Open-source workflow automation that we embed into platforms where non-technical operators need to configure automations without writing code. Particularly useful for Swiss SMEs with lean operations teams.
Our Process
We run an 8-week delivery cycle designed to minimize assumptions and maximize working software in your hands.- Week 1–2 — Discovery & Architecture: We map your SaaS product’s core user flows, define the data model, and produce a technical architecture document. For Swiss clients, this phase includes explicit decisions about data storage location, authentication method (including Swiss-preferred SSO options), and compliance requirements under nFADP or GDPR.
- Week 3–4 — Core Development: Backend API endpoints, database schema, authentication system, and the primary frontend views are built and functional. You can log in, navigate the core workflow, and see your product working — not a prototype, actual code running on a staging server.
- Week 5–6 — Integrations & Testing: Third-party integrations are wired in — payment processors (Stripe, which supports CHF natively), CRM connections, Swiss-specific tooling, or internal APIs. We run integration tests, load testing against realistic traffic scenarios, and security review of authentication and authorization logic.
- Week 7–8 — Deployment & Handover: Production deployment to your chosen infrastructure, SSL configuration, monitoring setup, and complete documentation handover. You receive full codebase ownership, infrastructure runbooks, and a 30-day post-launch support window. You’re not dependent on us to keep your product running.
Frequently Asked Questions
Can you build a SaaS product that complies with Switzerland’s nFADP data privacy law?Yes. nFADP compliance is primarily an architectural and process concern — data minimization, documented data flows, the ability to fulfill deletion requests, and clear data processing agreements. We design your database schema and application logic with these requirements in mind from the start, and we can provide technical documentation that your legal team or DPO can use to complete your compliance posture. What does it cost to build a SaaS MVP with Zargham Labs?
Our 8-week MVP engagements are typically scoped between $8,000 and $20,000 USD depending on feature complexity, number of integrations, and infrastructure requirements. This is significantly below what a comparable Swiss or Western European development agency would charge for the same scope — typically CHF 80,000–150,000. We’re transparent about scope before any contract is signed. Do you work with Swiss startups at the pre-seed stage, or only funded companies?
We work with both. Pre-seed founders who need an MVP to raise or validate with early customers are a core part of what we do. We scope engagements to match your budget reality and can structure phased delivery so you’re spending against validated milestones rather than committing a full budget upfront.
