Your Copenhagen SaaS Loads Like 2019. Your Competitors Ship in Next.js.

If you're a founder watching Vercel-backed rivals close deals faster, your stack is the friction point -- not your team.

We rebuild Copenhagen B2B SaaS products on Next.js 14 and Supabase, cutting page load times to under 1.5 seconds and shipping production features in two-week cycles. Full CET timezone overlap, EU-hosted Postgres by default, and Lighthouse 95+ on mobile — no trade-offs between speed and data residency.

Next.js SaaS Development for Copenhagen Founders

Next.js agency work for Copenhagen-based B2B companies means replacing slow, monolithic front-ends with server-component architecture that renders at the edge and integrates directly with Supabase row-level security. We handle the full delivery chain: architecture decisions, CI/CD pipelines, and post-launch performance monitoring. The result is a codebase your internal team can own, not a black box.

What is holding your current website back?

Common gaps we find in nearly every audit.

Your current stack takes three to five days to ship a feature that a Next.js app router project would ship in an afternoon, because every change requires a full rebuild and manual deployment.
Risk: Competitors running Vercel-hosted Next.js are iterating on user feedback in real time while your release cycle gives them a structural head start on every sprint.
Your SaaS loads in 4-6 seconds on mobile 4G, which is the actual network condition for many Danish B2B buyers checking demos on their phones between meetings.
Risk: A Lighthouse performance score below 70 directly correlates with higher bounce rates on demo landing pages, meaning paid acquisition spend is leaking before a prospect ever reads your value proposition.
Your customer data is routed through US-East AWS infrastructure because that is where your vendor defaults, creating a GDPR audit exposure you have not fully documented.
Risk: Enterprise procurement teams in Copenhagen and across the EU are increasingly blocking vendor sign-off when data residency cannot be confirmed, stalling deals at the final contract stage.

How We Build This Right

Every safeguard, built in from Day 1.

EU Data Residency by Default

All Supabase Postgres instances are provisioned in Frankfurt or Stockholm. No data transits US infrastructure at rest or in transit, and we document the architecture to satisfy your customers' DPA requirements.

Row-Level Security Enforced at Database Layer

We configure Supabase RLS policies so that tenant isolation is handled by the database, not application logic, reducing the attack surface for multi-tenant B2B SaaS and simplifying your SOC 2 evidence collection.

Lighthouse 95+ Mobile Performance Audit

Every production release is gated against a Lighthouse CI threshold of 95 on mobile. Core Web Vitals — LCP, CLS, and INP — are tracked per deployment so regressions are caught before they reach real users.

What We Build

Purpose-built features for your industry.

App Router Architecture with Server Components

We use Next.js 14 App Router with React Server Components to move data fetching to the server, eliminating client-side waterfalls and reducing JavaScript bundle size by 40 to 60 percent compared with pages-router equivalents.

Supabase Integration with Typed Database Clients

Database schemas are versioned with Supabase migrations and auto-generated TypeScript types, so your front-end and back-end contracts stay in sync across every pull request without manual interface maintenance.

Vercel Edge Deployment with CET-Aligned DevOps

Production deploys run on Vercel's edge network with preview environments on every branch. Because we operate on CET hours, code review, deployment approvals, and incident response happen during your working day, not overnight.

Incremental Migration from Legacy Stacks

For founders who cannot afford a full rewrite, we scope an incremental migration path that moves high-value routes to Next.js first while keeping your existing back-end live, so revenue is never interrupted by a big-bang cutover.

Our Development Process

From discovery to launch. Quality at every step.

01

Architecture Audit and Migration Scoping

1 week

We review your current stack, database schema, and deployment pipeline to identify the highest-impact migration targets. You receive a written scope document with a phased delivery plan and risk assessment before any code is written.

02

Foundation Build: Routing, Auth, and Data Layer

2 weeks

We establish the Next.js App Router structure, configure Supabase with RLS policies and typed clients, and set up CI/CD on Vercel with staging and production environments. This gives your team a working baseline to build against.

03

Feature Sprints with Fortnightly Releases

2 weeks

Product features are delivered in two-week cycles with a defined acceptance criteria and a stakeholder demo at the end of each sprint. Priorities can shift between sprints based on what your sales pipeline needs most.

04

Performance Hardening and Handover

1 week

Before final handover we run Lighthouse CI across all key routes, conduct a GDPR data-flow review, and produce internal documentation so your team can maintain and extend the codebase without depending on us for routine changes.

Frequently Asked Questions

No. Our studios are in London (HQ) and Los Angeles. We work with Copenhagen clients remotely and have done so successfully on multiple projects. London is just one hour behind CET, so our working hours overlap almost completely with yours -- typically 09:00-17:00 Copenhagen time. We run daily async updates in Linear and weekly video syncs. You won't notice the distance in practice.
Our London team starts at 08:00 GMT, which is 09:00 CET. That gives us a full eight-hour overlap with a standard Copenhagen workday. For anything urgent, Slack messages during that window get a response within 30 minutes. Our LA studio adds a second shift for overnight CI runs and async code review, so pull requests don't sit idle.
Yes. We set up i18n with next-intl or Paraglide, configure Danish (da-DK) as a first-class locale, and wire hreflang tags for SEO. We don't translate copy ourselves -- we'll work with your in-house team or a Danish copywriter you trust. The technical setup handles pluralisation, date formatting (dd.MM.yyyy), and Danish krone (kr) currency display correctly.
For most Copenhagen B2B SaaS products, Supabase gives you a Postgres database, auth, real-time subscriptions, and edge functions without hiring a separate backend team. Paired with Next.js server components, you get full-stack capability from a single codebase. That cuts your team size and infrastructure cost significantly compared to running a separate Node or Django API.
We configure Supabase on EU-region hosting so user data stays within the EU. Cookie consent banners follow the ePrivacy directive -- no tracking fires before explicit opt-in. We implement privacy-by-design patterns: data minimisation in your schema, automatic PII redaction in logs, and user data export/deletion endpoints for DSAR requests. We're not lawyers, but we build the technical controls that make compliance auditable.
Most projects land between DKK 80,000 and DKK 1,400,000 depending on scope. An MVP with auth, a dashboard, and Supabase backend typically runs DKK 150,000-300,000 over 8-10 weeks. Enterprise multi-tenant platforms with SSO, advanced RLS, and i18n sit higher. We provide fixed-price quotes after the scoping call -- no hourly billing surprises.
