Founder Institute Serbia Featured Mentor card for Marko Milojkovic, Founder, ETERNA Creative

I am a startup mentor at Founder Institute Serbia. I joined the mentor network with the 2025 cohort, gave a session and presentation to its founders, and hosted weekly office hours throughout the program. Applications for the next Serbia cohort are now open at fi.co/apply/serbia.

What mentoring looks like

FormatWhat it is
Session and presentationA session for the whole 2025 cohort
Weekly office hoursTime with founders from the cohort, every week of the program

The office hours were the best part. The cohort had strong startups, and the conversations were close to the ones I have with founders on a strategy call, just earlier in the journey.

What is new at Founder Institute

Founder Institute describes its new direction as becoming the world's largest AI-native company builder. The new FI Agentic Program combines:

  • purpose-built AI agents that help founders execute faster
  • intensive growth sprints focused on measurable progress
  • a proven company-building methodology
  • direct feedback from experienced founders, investors, and industry experts

Why this fits how we work

AI can speed up research, validation, customer discovery, and execution. It cannot replace judgment, trust, strategic thinking, or the experience of people who have already faced the problems of building a company. That is the same balance we build products on at Eterna, and you can see how we apply it on How we build with AI.

If you are validating an idea right now, start with the difference between startup research and validation and how I validated a startup idea before spending a single euro.

Apply, or share it with a founder

If you are working on an ambitious startup idea, or know a founder who should be, take a look at the program and apply for the next Founder Institute Serbia cohort. One recommendation can change a founder's path.

Thank you to the Founder Institute Serbia leadership team, Nedeljko Milosavljević, Tamara Čolić Milosavljević, and Đorđe Ćelić, for building this community.
