About Mantas
Growth Velocity Partner
Fractional CMO + AI systems builder + leadership coach. I help technical founders build marketing that works like engineering — systematic, measurable, and compounding.
Most marketing consultants give you a strategy deck. I give you strategy, working infrastructure, and a team that can execute without me.
The Journey
I spent 9 years leading marketing at Cherry Servers, a B2B infrastructure company. We grew from €4.3M to €16M in annual revenue. I built a 7-person marketing team from scratch, achieved 5:1 LTV/CAC, and drove 30% year-over-year growth.
But here is what I learned: marketing strategy was only 20% of the work. The other 80% was about getting the team unstuck. Founders who couldn't let go of decisions. Teams misaligned on priorities. Talented people underperforming because of dynamics nobody talked about.
That realization led me to train in Gestalt psychology and organizational consulting. Not as a career pivot — as a necessary expansion. The best marketing strategy in the world fails if the team executing it is blocked by patterns they cannot see.
In parallel, I went deep into AI engineering. Not just prompting tools, but building production systems — LangGraph agents, data pipelines, automation infrastructure. The kind of systems that turn a 3-person team into a force that operates like 10.
The result: a rare intersection of three disciplines that almost never exist in one person.
Three Disciplines, One Partner
Each discipline strengthens the others. Strategy without infrastructure stays theoretical. Infrastructure without psychology gets rejected by the team.
Growth Strategy
9 years leading B2B marketing. Built teams, systems, and channels that delivered 5:1 LTV/CAC at scale. From positioning and messaging through to pipeline generation and conversion optimization.
AI Engineering
Hands-on builder of automation and AI agents. LangGraph, data pipelines, production systems. I build the infrastructure myself — I do not just recommend tools and leave you to figure it out.
Psychology & Coaching
Gestalt-trained psychologist with an active organizational consulting practice. I diagnose team dynamics and founder patterns that others miss — the invisible blockers that keep good strategies from executing.
How I Work
Every engagement follows these principles. They are non-negotiable because they are what make the work stick.
Strategy + Infrastructure
Every engagement produces both direction and working systems. You get a strategy and the tools, automations, and processes to execute it — not a PDF that collects dust.
AI-Native
Automation is embedded by default, not bolted on later. Every workflow I design accounts for where AI can multiply output, reduce cost, or eliminate bottlenecks.
Documentation for Independence
SOPs, templates, and playbooks so your team can run without me. The goal is always to make myself unnecessary — that is how you know the engagement worked.
Measurable Outcomes
Clear before/after metrics for every engagement. If we cannot measure it, we do not do it. Progress is tracked in dashboards, not gut feelings.
Compounding Value
Systems designed to improve over time. Content libraries that grow. Automation that learns. Processes that get faster with each cycle. Month 6 should be dramatically more efficient than month 1.
