Where the marketing plan
gets stuck

We know that wait. A small marketing team has big targets, and a small change should not sit behind somebody else's roadmap.

Campaign pages wait in a queue while the campaign they belong to is ready to launch.

Your CMS, CRM and analytics are held together with workarounds.

Your team wants to work with AI, and nothing in your stack is wired up for it.

A new hero line or a form change needs a ticket and a slot on somebody else's roadmap.

The engineers who could do it are busy with the product.

The Root Cause

It happens because nobody technical works for marketing.

Websites aren’t one-time projects

Websites are long-living systems

We stay in touch

We never build and then just disappear.

Ask us anything

If you face any challenge, we are here for you.

Long-term ownership

We take technical ownership from day one.

No vendor lock-in

We build in your accounts or design for clean transfer.

Services

What we do for you

Our main service is ongoing work inside your marketing team. Migrations and new builds are the projects around it.

Fractional Marketing
Engineer

A small senior team that joins your marketing team and builds what the plan needs: pages and campaign work every month, with integrations and AI tooling on the Ownership tier. Month to month, nobody on your payroll.

Headless
Website

Your new website is built on a solid headless foundation. Editor independence and performance from day one.

Headless
Migration

Your website moves from a legacy CMS to a modern headless setup. SEO stays intact, performance improves, and your team gets a better workflow.

Agentic Marketing
Automation

Your marketing team builds and ships pages through your own headless CMS by chatting with a governed AI agent. No developer queue, with a human approving every publish.

Our Approach

Every project is design-led. We care about typography, hierarchy, and clarity, because good design reduces friction.

Technical excellence is baseline. Because responsiveness and clear communication is what separates good work from bad.

We build systems your team can operate through AI agents. Your team drafts and ships pages by chatting with an agent, and the component-based CMS keeps every page on-brand. The agents crawling your site can read it too.

Are we a match?

Who this is for

This works well if you

  • Are an established company with 30+ employees

  • Have a small marketing team with big growth targets

  • Manage multiple markets or languages

  • Are slowed down by your CMS or agency

  • Want fewer partners, not more

This is not a fit if you

  • Want a ready-made solution without custom development. See essentialweb.eu

  • Expect a handover without ongoing responsibility

  • Are early-stage with no internal marketing team

  • Prefer visual gimmicks over performance

How the monthly service works

1

We get to know your setup

We get access to your website and marketing tools, check how changes go live, and look at what you are about to launch.

2

You get a private Kanban board

Add requests whenever something comes up. You set the priorities, so we know which changes your launch depends on.

3

We build, check, and publish

We take the work through to the live site and keep you updated on the board. For a campaign page, that includes checking the form and tracking before traffic arrives.

Start with a Sprint

Start with a Sprint: one thing built and live, picked on the kickoff call.

If your stack cannot take the work, we say so on that call and you do not pay. If you sign up for a monthly tier within 30 days of the walkthrough, the Sprint fee is credited against your first invoice. Momentum and Ownership are month to month, and you can cancel or pause with 30 days notice.

How the service works

Results built on
real experience

We developed this proven model while working on complex, multi-market website migrations for companies managing hundreds of pages across multiple languages.

What clients notice

  • Faster publishing without fear of breaking things

  • Stable performance that doesn’t degrade over time

  • Fewer technical surprises after launch

  • Clear accountability when something needs attention

“David impressed me with his technical expertise, clear communication, and strong organizational skills during our redesign. If you want a skilled and personable partner, David is the one.”

About us

Essential Code

Essential Code is a micro agency from Vienna, Austria built around a very simple belief: a website is a living system. Someone must own it after launch, or it falls apart.

I’m David Wippel, owner of Essential Code. I’ve been working in web development for 20+ years. One constant pattern emerges after many projects: building it is the easy part. Keeping it alive and usable over time is where things get hard and messy.

Slow performance creeps in. Content workflows break. Small issues pile up. And the agency that built it is already three projects down the road.

That pattern needed to change.

Meet the Team

Essential Code is founder-led and works with a small network of trusted specialists. We also collaborate with adjacent experts in branding, marketing, content strategy, SEO, and infrastructure when projects require it.

How we work

  • Bigger is not better. We’re small by design. The people you meet are the people who build it.

  • Technical excellence is baseline. What separates good work from bad is respect for design and long-term ownership.

  • We don’t hand off projects and disappear. We stay responsible.

What’s a micro agency?

A micro agency is deliberately small and built for focused, long-term partnerships. The people you meet in the first call are the people who build your site.

You work directly with the people doing the work, with no account managers in between and no bait-and-switch.

Essential Code is your Fractional Marketing Engineer: a small senior team that joins your marketing team and builds what your marketing plan needs.
