What a London-Based Next.js Agency Actually Delivers to Copenhagen — Without the Købmagergade Lease

Your buyer lands on your SaaS dashboard at 09:47 CET. The server component streams in 380ms. Authentication resolves through Supabase in under 600ms. The first meaningful paint hits before your competitor's WordPress admin panel even loads its CSS. We don't rent office space in Østerbro. Our London HQ sits one hour behind you, which means your product manager's Slack at 10:00 Copenhagen time hits our team mid-morning — full overlap from 09:00 to 17:00 CET without the DKK 85K/month lease overhead. We've shipped multi-tenant SaaS platforms for Danish founders who needed App Router server components, Supabase row-level security configured for EU data residency, and next-intl pipelines that handle Danish pluralization rules without breaking English SEO. Your engineering budget stops bleeding on junior React contractors when you work with a studio that's built 40+ production Next.js apps. Every pull request gets a Vercel preview URL. Every deploy passes Playwright E2E checks. Your Datatilsynet compliance audit doesn't fail because we configured Supabase EU hosting and cookie consent flows from sprint one.

Waar projecten falen

Danish SaaS founders paying Copenhagen agency rates for junior React developers DKK 150K+ burned on a codebase that can't scale past 10 tenants
Legacy WordPress or PHP storefronts losing ground to faster Danish competitors Bounce rates climbing as Core Web Vitals scores drop below Google thresholds
B2B dashboards with server-rendered pages that break on every Next.js version bump Engineering time spent on migration debt instead of shipping features
No clear GDPR/Datatilsynet-compliant auth and data residency strategy Regulatory fines up to 4% of annual turnover under EU enforcement
Multi-language support bolted on as an afterthought — Danish, English, Swedish all half-done Nordic customers churn when the product feels like a bad translation
SaaS products stuck on client-side rendering with visible layout shift Enterprise buyers in CPH judge credibility by perceived performance — slow apps lose deals

Wat we bouwen

Ship App Router server components with parallel routes and streaming SSR that hold stable across Next.js version bumps

Your B2B SaaS scales past 10 tenants without a rewrite — server components handle 500+ concurrent users on a single Vercel instance

Deploy Supabase auth with EU-hosted Postgres, magic links, SSO, and row-level security policies that pass GDPR audits

Your storefront beats Danish competitors on Core Web Vitals — LCP under 2 seconds even on 4G mobile in Aarhus

Build next-intl or Paraglide i18n with proper Danish locale support, pluralization, and hreflang tags across da/en/sv/no

Your team stops burning DKK 40K/month on migration debt — we build on stable App Router patterns that survive Next.js updates

Launch headless Shopify or Medusa storefronts on Vercel edge nodes with ISR product pages under 1-second TTFB

Your compliance team clears Datatilsynet audits — EU-region Supabase hosting and cookie consent flows ship in sprint two

Stream real-time data tables and notification feeds using Supabase Realtime paired with React Server Components

Your Nordic customers stay because the product feels native — Danish, Swedish, Norwegian translations load without layout shift

Automate Lighthouse checks, Sentry error tracking, and Playwright E2E tests in every CI/CD pipeline from day one

Your enterprise buyers in Copenhagen close deals faster — Lighthouse 95+ mobile scores signal credibility before the demo call

Ons proces

Figma components built on Radix or Shadcn. Supabase database schema, RLS policies, and edge functions defined. You approve both before a line of production code ships.
Week 2-3
03

Core build sprint

Next.js App Router scaffolding, auth integration, primary routes, and API layer. Daily preview URLs so your product team in Copenhagen can click through progress.
Week 4-7
04

i18n, testing, performance

Danish and English content wired through next-intl. Playwright E2E coverage on critical paths. Lighthouse audits targeting 95+ on mobile for every key page.
Week 8-9

Production deploy to Vercel with custom domain, monitoring, and Sentry. Full documentation in Notion. Optional retainer for ongoing feature work and Next.js upgrades.
Week 10

Veelgestelde vragen

Do you have an office in Copenhagen?

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.

How does the CET timezone overlap actually work?

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.

Can you handle Danish-language content and localisation?

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.

Why Next.js + Supabase instead of a traditional backend?

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.

How do you handle GDPR and Datatilsynet requirements?

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.

What does a typical Copenhagen B2B SaaS project cost?

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.
