SaaS Development Services We Offer in Copenhagen
Copenhagen SaaS buyers compare your output to Pleo's expense dashboard, Trustpilot's review widget, Templafy's enterprise admin, and Famly's parent-and-staff UX. Our SaaS development services match that bar. We build Next.js 15 multi-tenant apps with row-level security on PostgreSQL or schema-per-tenant where compliance demands isolation, NestJS and FastAPI backends for typed APIs and queue-driven workflows, Stripe Billing, Chargebee, and Paddle for revenue ops including DKK, EUR, GBP, USD pricing and EU and UK VAT, MitID and MobilePay integrations for Danish citizen and consumer flows, and design systems that capture the Scandi-design aesthetic (generous whitespace, IBM Plex or Inter typography, restrained colour, accessible contrast) without copying any single brand. Every build ships with a GDPR-by-design data model, audit logging, role-based access control, SOC 2 and ISO 27001 readiness artefacts, and an EU Accessibility Act 2025 conformance plan from day one.
Our SaaS Development Development Process
We run discovery, design, build, and launch on CET hours so Copenhagen founders, DPOs, and revenue leads get synchronous standups, not next-day handoffs. Discovery opens with a GDPR Article 35 DPIA, a Datatilsynet-aligned data flow map, a Schrems II Transfer Impact Assessment where US sub-processors are in scope, and a Finanstilsynet outsourcing review for fintech SaaS. The pricing and packaging workshop sets DKK, EUR, GBP, and USD price points, VAT MOSS or OSS registration scope, and the trial-versus-freemium model. Build sprints are two weeks. Launch includes SOC 2 Type I readiness, ISO 27001 gap assessment, EU Accessibility Act 2025 conformance statement, and a 30-day post-launch reliability and conversion watch.

Technologies We Use for SaaS Development
We default to Next.js 15 with the App Router for SaaS frontends, NestJS or FastAPI for typed backend services, PostgreSQL on Supabase or Neon for primary storage with row-level security multi-tenancy, Redis for sessions and queues, and BullMQ or Inngest for background jobs. Hosting splits between Vercel and Cloudflare for the global frontend, AWS eu-west-1 (Dublin) or eu-north-1 (Stockholm) for the primary backend (these are the closest AWS regions to Copenhagen since there is no Danish AWS region), Azure West Europe (Amsterdam) where Microsoft-aligned enterprises specify it, and GCP europe-west1 (Belgium) where Google standards apply. Stripe Billing, Chargebee, and Paddle handle revenue ops with EU and UK VAT. MitID integrates through OIO IDWS for citizen-facing flows and MobilePay Subscriptions for recurring DKK payments. Auth uses Clerk, Auth0, or self-hosted Authentik with passkeys, and SOC 2 and ISO 27001 controls run through Drata, Vanta, or Secureframe.
