GTM Engineer · Belgrade, Serbia

Who is Mihajlo Maiga?

I build outbound systems for B2B companies - the data, the copy, the sending infrastructure, and the automation that keeps them running.

What I actually do

A company tells me who its best customer is. I turn that into a system that reaches them: sourcing and enriching the list, splitting the market into segments that deserve different messages, writing and wiring the copy, standing up the domains and inboxes, and building the checks that stop a bad row from reaching a real person.

How I work

Manual first, automated second. I run a segment by hand until it produces replies, then automate the parts that proved themselves. Most outbound fails because it was automated before it worked, not because the tooling was wrong.

Where I work

Most of my work runs through Prospeqt, where I handle several clients at once. I am based in Belgrade, Serbia, and work with teams across Europe and the US.

Common questions

Who is Mihajlo Maiga?
Mihajlo Maiga is a GTM engineer based in Belgrade, Serbia. He builds the outbound systems behind B2B pipeline: lead data and enrichment, cold email infrastructure, segmentation and copy systems, and the automation that keeps them running. Most of his work runs through Prospeqt, where he handles several clients at once. He is also the founder of Young Professionals Club (YPC), an invite-only community for young professionals. Before that he hosted the Ubrzzzanje podcast, coordinated the Mentor the Young programme, and was chairperson of EESTEC LC Novi Sad.
What does a GTM engineer do?
A GTM engineer turns a company's idea of its best customer into a working system that reaches them. In practice that means sourcing and enriching the lead list, splitting the market into segments that deserve different messages, writing and wiring the copy, standing up the sending domains and inboxes, and building the checks that stop a bad record from reaching a real person. It is closer to data and infrastructure work than to sales.
What tools does Mihajlo Maiga use?
Clay for enrichment and routing, Instantly and EmailBison for sending, n8n for workflow automation, Claude Code and Codex for building tools, Prospeo for contact data, Render for hosting, Supabase for storage, Slack and ClickUp for coordination, and tldraw for diagramming. No affiliation with any of them.
How does Mihajlo Maiga approach outbound?
Manual first, automated second. He runs a segment by hand until it produces replies, then automates only the parts that proved themselves. His view is that most outbound fails because it was automated before it worked, not because the tooling was wrong.
Who is Mihajlo Maiga not a good fit for?
Companies that need meetings inside a week, since the data work comes first and takes longer than that. Companies chasing the cheapest possible sending volume, which is the fastest route to a burned domain. Companies selling to consumers rather than other businesses. And anyone who wants the sending handed over and never looked at again.
What is Young Professionals Club (YPC)?
Young Professionals Club is an invite-only community for ambitious young professionals, founded by Mihajlo Maiga in February 2024 and based in Serbia. It brings together career-driven people who want to expand their networks and build skills, through curated meetups, peer-led events, expert sessions and multi-day growth retreats.
Does Mihajlo Maiga have a podcast?
He founded and hosted Ubrzzzanje, a podcast for young people about accelerating their development, in a career and outside one. It ran from December 2023 to January 2025 and passed 15,000 views. The name is a physics joke: acceleration is the rate at which speed changes.
Where is Mihajlo Maiga based and who does he work with?
He is based in Belgrade, Serbia, and works with B2B teams across Europe and the United States. He can be reached at mihajlo@prospeqt.co.
