Your deploy ships to Vercel Edge, and a Stockholm buyer hits your SaaS landing page in 890ms. That's Server Components doing the work — no JavaScript bundle stalling the paint, no client-side auth dance before content renders. Your fintech stack needs real-time dashboards, PSD2-compliant flows, and Postgres audit trails that survive Finansinspektionen scrutiny. We build that on Next.js 15 App Router + Supabase from London HQ, with CET overlap from 09:00–18:00 Stockholm time — one timezone behind, zero async gaps. Your team gets senior engineers in shared Linear + Figma workspaces, daily standups in English, and payment integrations tested against Swedish bank sandboxes before your first transaction fires. No six-month Stockholm hiring cycle burning SEK 70K monthly before you ship a feature.

常見問題
Do you have an office in Stockholm?
No. Our studios are in London (HQ) and Los Angeles. We've worked with Stockholm-based fintech and SaaS teams remotely, and the setup works well — London is one hour behind CET, so we're online together for the full Swedish working day. Communication runs through Linear, Slack, and weekly video syncs. We don't pretend to be local, but the timezone math means you won't feel like we're offshore either.
How does the CET timezone overlap actually work day-to-day?
London is GMT/BST, which puts us one hour behind Stockholm. In practice, our team is available 09:00–18:00 CET during your working day. Daily async standups go out by 09:30 your time. Video calls are scheduled mid-morning or early afternoon CET. Our LA studio adds a second shift for anything that needs US-hours coverage — useful if you're running a SaaS with American customers too.
Can you handle Swedish-language content and i18n properly?
Yes. We set up Next.js middleware-based locale routing so Swedish and English (or additional locales) each get their own URL prefix, correct hreflang tags, and per-locale sitemaps. We don't do translation — you'll provide the Swedish copy or we can coordinate with your translator — but the technical i18n architecture is something we've done many times and it won't break your SEO.
Why Next.js + Supabase for Swedish fintech SaaS specifically?
Stockholm fintech products tend to be data-dense, auth-heavy, and subject to financial regulation. Next.js server components let you run payment logic server-side without exposing it to the client. Supabase gives you Postgres with row-level security — meaning you can enforce data access rules at the database level, which auditors and compliance teams actually understand. It's a stack that scales without requiring a massive DevOps team, which matters when you're a 15-person startup burning through a Series A.
Do you support Swish and Klarna payment integrations?
Yes. We've integrated Swish for Business (via their API) and Klarna Checkout/Payments in Next.js apps. We also work with Stripe Connect for marketplace-style flows. Each integration gets tested against sandbox environments before going live, and we build webhook handlers with idempotency keys so you don't end up with duplicate charges — a surprisingly common bug in payment integrations.
What does a typical Stockholm project cost and how long does it take?
Most projects fall between SEK 120K and SEK 2M depending on scope. A focused MVP — say a payment dashboard with auth and one integration — runs about 8–10 weeks and lands in the lower range. A full SaaS platform with multiple payment providers, admin panels, and compliance features can take 14–20 weeks. We scope everything upfront with a fixed-price option available after the architecture phase, so there are no surprises.
