About

Team

The people behind hafencity.dev.

Dedicated contacts, clear accountability, and a team that brings strategy, design, and engineering together.

Principles

Four things we don't compromise on.

01

Senior leads, end to end

Every engagement is led by a senior practitioner from kickoff to ship. The supporting cast may scale up or down with the work, but the lead — and the accountability for delivery — stays with one person you can call.

02

Under one roof in Hamburg

Strategy, design, and engineering all live at our Hamburg HQ. The work happens here — briefed, built, and accountable to you, with one project lead from start to finish.

03

Outcomes over deliverables

We're hired for results, not slides. Our success metric is your product shipping, scaling, and earning trust in production — not a stack of artefacts a procurement reviewer can tick off.

04

Long-term partnerships

Most clients stay multiple years. We're built for compounding trust — not for closing deals — which means we say no to engagements that aren't a fit, and yes to the ones we can actually move forward.

Founder story

Why we started hafencity.dev.

Marius had just completed the exit of a startup he had built in 2023. Soon after, he approached Hauke with the idea of founding a software agency that helps companies move serious digital initiatives forward.

His only condition was simple: fewer meeting loops, more actual implementation. He wanted to build software projects, not just talk about them.

Hauke was immediately in. After five years building highly available enterprise systems, this was exactly the next step he wanted: take on new projects, build ambitious products, and stay responsible from first concept through launch.

How we work

From whiteboard to production, one lead owns it end to end.

Five phases, one project lead from start to finish. No handoffs, no "that's not our part".

  1. 01

    Discover

    Goals, constraints, success metrics.

  2. 02

    Define

    Strategy, scope, and a roadmap you can defend.

  3. 03

    Design

    UX, UI, and the system foundations under them.

  4. 04

    Build

    Engineering with QA embedded, not bolted on.

  5. 05

    Operate

    Live monitoring, iteration, and growth.
