What We Offer
Our MVP development service for UK startups is scoped around one goal: getting something real in front of your first users within eight weeks. Here’s exactly what that includes:- Full-Stack SaaS MVP Builds: We design and build production-ready MVPs using FastAPI on the backend and Next.js 14 on the frontend. You get a real application — authenticated, deployed, and usable — not a prototype that needs to be thrown away before you can scale.
- AI Automation Integration: If your product involves AI workflows — lead scoring, document processing, intelligent notifications, or GPT-powered features — we wire those in as core functionality, not bolted-on add-ons. UK SaaS founders in fintech, proptech, and legaltech have particularly found this useful.
- WhatsApp Business Automation: Through Messenjo, our live WhatsApp Business platform, we can integrate WhatsApp-based customer communication directly into your MVP. This is especially relevant for UK businesses targeting SME markets where WhatsApp adoption is high and email open rates are not.
- Workflow Automation with n8n: We build internal automation pipelines — CRM syncs, notification triggers, onboarding sequences — using n8n, so your MVP ships with operational infrastructure already in place, not just a front-end skin over a database.
Why Choose Zargham Labs
There are hundreds of development agencies in the UK and thousands offshore. Here’s what actually separates us:- Founder-Direct Execution: Zargham personally architects, reviews, and delivers every project. You will never be handed off to a project manager who relays messages to an unnamed developer. UK founders specifically tell us this is the single biggest differentiator — you get senior technical judgment on every decision, not account management.
- Messenjo Is Our Proof: We don’t just talk about building SaaS products — we operate one. Messenjo (messenjo.io) is a live WhatsApp Business automation platform built on the exact same stack we’d use for your MVP. When we say we know how to build scalable multi-tenant SaaS, we have a production system running to back that up.
- US-Registered, Transparent Contracting: For UK clients, working with a US LLC means clean contracts, straightforward invoicing in USD or GBP, and a commercially accountable entity. You’re not dealing with a freelancer who disappears after delivery.
- Fixed-Price MVPs from $5,000: Our engagements are scoped and priced upfront. No hourly billing surprises, no scope creep invoices. UK startups on pre-seed or seed budgets can plan against a known number.
Our Tech Stack
We don’t rotate stacks based on trends. We use the same production-tested technologies across every project because consistency means fewer bugs and faster delivery:- Python FastAPI: Fast, typed, and production-ready. Ideal for SaaS backends where you need solid API performance without the overhead of Django or the instability of a newer framework. UK fintech and legaltech MVPs particularly benefit from the strong type safety.
- Next.js 14: Server components, app router, and SEO-ready architecture out of the box. Your MVP frontend will be fast enough to impress investors and structured well enough to scale without a rewrite.
- PostgreSQL + PgBouncer: A relational database with connection pooling that handles real production load. Not an over-engineered distributed system, not a toy SQLite instance — the right choice for an MVP that needs to graduate to scale.
- Celery + Redis: Background task processing for anything that shouldn’t block a user request — email sends, webhook processing, report generation. Essential for SaaS products where async reliability matters from day one.
- Docker + Traefik: Containerised deployment with automatic SSL and reverse proxying. Your MVP ships properly hosted, not running on a shared Heroku dyno that goes to sleep.
- n8n: Visual workflow automation for connecting third-party services — Stripe, HubSpot, Slack, or whatever your UK business stack requires — without building every integration from scratch.
Our Process
Eight weeks is a real timeline, not a marketing claim. Here’s how it works in practice:- Week 1–2 — Discovery & Architecture: We map your core user journeys, define the MVP feature set ruthlessly (cutting anything that doesn’t validate your primary hypothesis), and produce a technical architecture document. For UK SaaS products, we also assess GDPR data handling requirements and UK-specific compliance touchpoints at this stage.
- Week 3–4 — Core Development: Backend API, database schema, authentication system, and primary user flows are built and functional. You’ll have a staging environment to review by the end of week four — not mockups, a running application.
- Week 5–6 — Integrations & Testing: Third-party integrations go in — payment providers (Stripe is common for UK products), AI services, WhatsApp Business API if applicable, and any data pipeline automation. End-to-end testing covers the critical paths your first users will hit.
- Week 7–8 — Deployment & Handover: Production deployment on your infrastructure, DNS and SSL configuration, monitoring setup, and a full handover including documentation, codebase walkthrough, and a recorded technical briefing so your team or future hires can pick up where we leave off.
Frequently Asked Questions
How does working with a US-based company work for UK startups practically?Contracts are issued under US LLC terms, invoicing is straightforward in USD or GBP via wire transfer or Wise, and all communication happens over email, Slack, or video call in UK-compatible time zones. Many of our UK clients find the arrangement cleaner than working with a UK agency because the scope, price, and deliverables are defined upfront with no ambiguity. What makes your MVP development approach different from other offshore agencies targeting UK startups?
Most offshore agencies selling to UK startups assign you a project manager as a buffer between you and the actual developers. At Zargham Labs, the person you speak to is the same person writing the architecture and reviewing the code. We also operate a live SaaS product ourselves, which means we make decisions based on what actually works in production — not theoretical best practices from a sales deck. Can you build an MVP if I only have an idea and no technical specification?
Yes — this is the norm, not the exception. The discovery phase in weeks one and two is specifically designed to take a founder from idea and user problem to a scoped, buildable specification. We’ll challenge assumptions, cut features that don’t need to be in the MVP, and produce a technical plan before a single line of code is written.
