THE PEOPLE BEHIND Z-CONSULT
Z-Consult brings together strategic thinking, digital expertise, discipline, and real execution. We didn't create the company to be just another agency. We created it to connect the pieces that too often work separately.
Business · Strategy · SEO/BEO · Paid Growth · Data · People · Execution
"Different experiences don't divide us. They are why the system works."
01 / BEFORE Z-CONSULT
It begins much earlier — with the first websites, the first mistakes, the first clients, difficult decisions, and the years during which each of us built our own way of thinking.
Before Z-Consult existed, there were three distinct professional paths. One began with creating proprietary online projects. The second was built through discipline, management, and continuous adaptation. The third brought over a decade of accumulated expertise and professional depth.
Z-Consult isn't the start of this experience. Z-Consult is the moment it began to function as one system.
The Convergence Timeline
2006
Martin Zhelyazkov began building and developing his own websites. This accumulated practical experience not only in traffic but also in content, monetisation, user behaviour, and genuine responsibility for results.
02 / WHY Z-CONSULT
The problem was rarely only in SEO, advertising, content, or the website. The problem was in the broken connection between them.
Strong analyses and presentations that do not reach production.
Many reports, but insufficient clarity on what needs to change.
Activities that look right in channels, but do not follow actual priorities.
Marketing, sales, product and development are working, but not towards the same goal.
Technologies accelerate processes, but can also accelerate wrong decisions.
Tasks exist, but it's unclear who is responsible for the final result.
Z-Consult was created to bridge these disconnections.
03 / THE LEADERSHIP TEAM
A strong system is not built from three identical viewpoints. It is built when different viewpoints can challenge, complement, and converge into a single solution.
Founder of Z-Consult
Strategy, systems and an uncompromising approach to work without a clear reason.
From the first proprietary websites to building comprehensive business systems.
Martin began his journey in 2006 with his own online projects. This practice gradually led him to SEO, digital marketing, consulting, teaching, and working with complex businesses.
„I don't think about problems. I think about solutions.“
Leadership Team
Discipline, adaptation, and growth without excuses.
Turning limitations into a system for development.
Evgeni's professional path combines digital marketing, business management, and sports discipline. He worked at a high level in one of Bulgaria's largest digital agencies and developed a mindset based on long-term goals and continuous adaptation.
„When you ask the right questions, you find solutions.“
Leadership Team
Experience, depth, and control over detail.
Over 12 years of experience, transformed into mature professional judgment.
Serhat Mustafa is a specialist with over 12 years of professional experience and part of the Z-Consult leadership team. He adds accumulated expertise, resilience, and judgment, built through real work, to the overall system.
The Leadership Decision Engine
When examining a problem, we don't start from identical positions. One looks for the systemic cause. Another checks how the solution will work for growth. The third adds experience and control over actual execution.
Viewpoint
Strategy
Is the problem in traffic, or in the offering, structure, UX, and measurement method?
Viewpoint
Growth
Even if we increase visibility, can the business convert additional demand into value?
Viewpoint
Execution
Which teams, tasks, and dependencies need to be activated for the solution to reach production?
Z-Consult solution
Common priority, owners, sequence, and measurement.
An illustrative example of our way of thinking.
04 / THE CONVERGENCE
The initial idea was a partner who understands business beyond individual marketing channels. With the addition of Evgeni's and Serhat's diverse experience, this idea gained greater scope.
We don't seek quick agreement. We seek the right solution.
05 / THE MISSION
Z-Consult's mission is to connect business, marketing, data, people, and execution into a system that can be understood, managed, and developed.
Context
We understand the business reality before recommending action.
06 / THE VISION
We want businesses to understand why every activity exists, what value it should create, who is responsible, and how the next decision is made.
We don't want
We want
Success is not an accident. It is the result of clear direction, discipline, and a system.
07 / THE PRINCIPLES
Business before channel
SEO, advertising, content, and AI have no standalone value if they don't serve a real business objective.
No strategy without execution
Analysis is useful only when it can be converted into concrete actions.
No report without a decision
Data must lead to a next question, priority, or change.
No universal package
Components and roles are determined by the specific business context.
We don't hide behind terminology
Complexity must be translated into clear business language.
Automation does not replace judgement
AI and algorithms speed up work, but the responsibility for the decision remains human.
Quality has an owner
Every important task must have an owner, a criterion for completion, and verification.
Priorities can change
The plan must follow reality, not ignore it.
We also say what should not be done
Professional recommendation is not always more activity.
08 / THE EVOLUTION
They are the result of problems we saw again and again — different channels, teams, and data not working as a single system.
BEO emerged when it became clear that organic growth no longer depends solely on keywords and links. It also depends on the offering, structure, content, UX, trust, data, and execution capability.
From search engine optimisation to optimisation of the entire business system behind organic growth.
PGS emerged when it became clear that advertising campaigns cannot be managed in isolation from the offer, creatives, sales process, measurement, budget, and the business's real capacity.
From campaign management to managing the system behind paid growth.
Both systems follow one philosophy: first the business context, then the marketing solution.

Read about BEO10 / WHEN YOU WORK WITH US
You will get different perspectives that must lead to a defensible solution.
We will ask why
Before discussing a channel, task, or budget, we need to understand the business reason.
We will challenge the obvious solution
The problem seen first is not always the main problem.
We will translate complexity
Technical and marketing details must be understandable to the business.
We will involve the right people
The solution may require marketing, sales, product, content, design, development, or management.
We will define what we will not do
Focus requires not only choosing actions but also abandoning secondary ones.
We will stay until execution
The strategy must reach a task, owner, acceptance criteria, QA, and measurement.
We don't sell certainty where there is none. We provide clarity on how the next decision should be made.
11 / BEYOND METHODOLOGIES
Martin
Builds, teaches, and transforms complex ideas into clear systems.
Evgeni
Combines business goals, sports discipline, and daily adaptation.
Serhat
Brings over 12 years of professional experience and composure in complex situations.
Professionalism does not exclude human connection. It demands it.

12 / WHAT WE ARE BUILDING
We want it to be the partner businesses turn to when the problem is too important for a superficial solution.
We are building a company where strategy is not separate from execution. Data is not separate from business judgment. AI is not separate from human responsibility. And experts do not work as isolated functions.
Three different paths. One shared responsibility — for the work to be meaningful.
