How I work

I design your GTM strategy and build the system that executes it. You get a full GTM strategy + hands-on execution, done by one operator, end-to-end.

I'm a Revenue Growth Engineer

What does that mean?

Revenue

I own business outcomes. Pipeline, win rates, expansion euros. Zero vanity metrics.

Growth

Upsell, cross-sell, retention, expansion. Anywhere your company needs to grow revenue.

Engineer

I build systems and write actual code. I'm a workflow builder, not slide maker.

01

Deep Discovery

I start by understanding everything about your business before touching a single tool. Your buyers, your deals, your competition, your tech stack. I map the full picture so the strategy is built on evidence, not assumptions.

02

GTM Strategy

I define who to target, why, what to say, and where — prioritized by real signals and your actual resources. You get a plan your team can execute, not a 60-page deck that sits on a shelf.

03

System Design

I design and build a connected GTM system: setup Claude Code to run on your private Git, connect the tools (CRM, Clay/Cargo, Lemlist/Instantly, Database, Apollo etc.), write the code, create the workflows and feedback loops, test everything.

04

Implementation & Optimization

I implement your GTM system where every deal makes the system smarter. Everything talks to everything and you can see your deals grow.

István

Hi! My name is István.

But those that work with me just call me Pisti. I've spent 11 years building growth systems for brands that needed to scale fast and spend smart.

I worked as an agency lead with global brands like Nokia, Mastercard, Wizz Air, and Decathlon. I learned a lot about how to reach the right people and more importantly: how to make them buy.

Recently I started Sonder to do what I'm best at: creating smart strategies and building systems to run them. I like working with founders who don't need another deck, they need someone who gets the work done.

If that sounds like what you need, let's talk.

Let's start building your GTM system!

Tell me what your goal is, what you have, and what you need and I'll create a plan where you see exactly what I'll build and how.
