For performance and lead-gen agencies

Everyleadandeveryeuro.Oneoverview.

You manage spend and leads for multiple clients across five separate tools. We bring it all together in one dashboard: which campaign, which channel and which euro actually delivers results. Per client, in real time.

The problem

Your reporting is manual work, and nobody sees which channel actually pays off.

Merging figures from Meta, Google, email and your CRM by hand in spreadsheets. Every month again, for every client. Meanwhile the question of which euro brings in a client stays unanswered.

One dashboard per client. No more monthly copy-and-paste, and finally attribution that adds up.

Separate systems, manual connections, leads leaking away.

How it works

From scattered tools to one live dashboard.

Connect

We connect your ad platforms, email, CRM and telephony through their APIs. Nothing to retype, no migration.

No migrationweek 1

Unify

All leads and all spend come together in one model, with attribution and ROAS per channel and per client.

One source of truthweek 2

Automate

Lead routing and client reporting run automatically. The numbers are ready before your client asks.

No manual workongoing

2-3weeks to first evidence

First we define what good looks like. Then we build and test in shadow mode, without irreversible actions.

WHY OUTPUT QUALITY MATTERS

He found out after five months that he was not properly insured. Cost: $30,000.

The problem was not a lack of software. The governing rule, owner and escalation path did not exist as one executable standard. An agent without that structure could work faster and still make the same mistake. That is why Studio Zakai starts with the definition of correct, not with the tool.

WHAT WE DELIVER

Six fixed quality controls, independent of the runtime.

Your operating standard remains portable when the runtime, model or vendor changes.

The Workflow Blueprint and Knowledge Pack capture the operating method. The Quality Contract defines which output is good enough and when a change may reach production.

Source hierarchy

Every conclusion points to the governing source. Conflicts and missing context are surfaced, not invented.

Decision rules

Categories, thresholds and failure conditions are made explicit before an agent executes the process.

Exceptions and approvals

We define when the workflow stops, who decides and which permissions are deliberately withheld.

Fixed evaluation set

Real, approved examples test classification, content, style and critical failure checks.

Release gate and rollback

A new prompt, rule or model version only goes live after a passed test and explicit approval.

Monitoring and feedback

Corrections, incidents and reviewer edits are stored append-only and inform the next candidate version.

The quality cycle

Before buildSources, rules, exceptions and owners are approved.

Before releaseThe candidate version runs against the same fixed evaluation set.

In productionCritical failures, overrides and exceptions remain visible.

During improvementA reviewer approves both the change and the evidence behind it.

Feedback therefore never pushes a prompt live automatically. The system proposes a candidate improvement, tests it and waits for approval.

In practice

Built around real work.

Studio Zakai works on marketing operations at scale, international obligations and a safari back office. The implementation changes, the quality layer stays consistent.

De ZaakIn production

Marketing operations on a platform serving 144,000 entrepreneurs

Lead routing, campaign workflows and reporting run on one operational layer with more than six live integrations.

Obligations monitored across five countries

Two CEO environments bring sources, owners, deadlines and escalations together without giving away decision authority.

Rate data out of scattered price lists

The first tariff database turns lodge price lists into source-backed rate rules. Booking steps, payment moments and documents follow in the same back office.

Lead Attribution Dashboard Pilot

Start with one module. See results first.

We start with one module: the dashboard that brings your leads and your most important channels together, filled with your own data. You see what it delivers within weeks, before you expand further.

You only decide whether we expand after the pilot. No big platform up front, just one working module that proves its value.

WHO BUILDS IT

A former lawyer who treats critical workflows like case files.

I am Justus, founder of Studio Zakai. My legal background taught me to capture sources, exceptions and accountability precisely. As a systems builder I make that logic executable and testable.

I do not sell a model or server as the solution. First we define correct output. Then we build and test the workflow in the environment that fits best.

You work directly with me. Your company keeps the data, accounts, decisions and portable documentation.

Legal precisionSources, rules and exceptions remain traceable.

Runtime neutraln8n, Cowork, Copilot or custom code are execution choices.

Client ownershipData, credentials and decision rights remain yours.

Frequently asked questions

Everything you want to know

Practical answers about scope, quality, access, privacy and cost.

Don't see your question?
Ask it in the 30-minute call.

Via API or webhook to almost any modern system: Meta and Google Ads, email platforms like Copernica or Mailchimp, CRMs, telephony and accounting. In the first session we test the connection with your specific stack.

A first working dashboard with your own data is usually ready within 2 to 3 weeks. We start with the source that delivers the most value and build out from there.

The difference is in the connection and the automation. A BI tool shows data you feed into it yourself. We build the pipelines that connect your tools, deduplicate and route leads, and make attribution add up. The dashboard is the visible part, not the work.

That's usually the starting point. We build a canonical layer that aligns naming, channels and statuses, so the figures from your different tools finally agree with each other.

Processing on EU servers, GDPR-compliant by design, under a data processing agreement. No data to the US.

A one-off build price for the setup and connections, plus a monthly fee for hosting, monitoring and further development. The exact scope depends on your tools and sources, which we determine together in the first conversation.

Next step

Map one critical workflow clearly.

We take your tools and figures as an example and show what your dashboard will look like. Concrete, tailored, in 30 minutes.
