It started by putting a hundred mentors in a student's pocket. Now it helps whole organizations learn to work with generative AI - and keeps the humans at the center of the switch.
Here is a thing that usually happens to education-technology companies when a technology as large as generative AI arrives: they get run over by it. Students who once needed a platform to reach a mentor can now, in theory, ask a chatbot. 100mentors, founded in Athens in 2015, looked at that problem and did something less common than surviving - it changed what it sold while keeping what it was good at.
The original 100mentors was a straightforward, useful idea. Teenagers make enormous decisions - what to study, what career to chase - based on almost no first-hand information about the jobs in question. So the company built an on-demand network connecting more than 21,000 students across partner schools in 17 countries with roughly 2,500 mentors drawn from top universities and companies. Students picked an industry, nominated mentors, set the agenda; mentors answered from their phones between meetings. The company's quiet competence was logistical: getting scarce expertise to the exact person who needed it, at the moment they needed it.
That competence turned out to transfer. When generative AI arrived and every enterprise on the continent started asking how to actually use it, 100mentors noticed the bottleneck was not the model. Anyone can buy a license. The hard part is getting a 400-person company to work differently - to change the meeting, the workflow, the person who was never trained. So 100mentors repointed its expertise-delivery machine at organizations, and became, in its own words, "your enterprise partner in Generative AI adoption."
Adopt Generative AI. Drive team-level adoption. Fuel organizational impact.100mentors - company positioning
There is an honesty to the pivot worth noting. The company did not pretend the new mission was secretly the old one. Student mentorship became enterprise AI adoption - a different customer, a different sale, a different economics. What carried over was the underlying belief: keep the human at the center, and the technology follows. It is a slightly unfashionable stance in a market that mostly wants to talk about tools, and it is the thread that runs through all three of the company's current products.
100mentors packages AI adoption into three moving parts - learn it, run it, gather around it. Each one solves a different point where organizations tend to stall.
Customized generative-AI bootcamps that take an organization from fundamentals to department-specific mastery - training people to use AI in their actual workflows, not in the abstract.
An AI-powered meeting platform built to make team meetings sharper and more strategic in the generative-AI era - the daily-habit product that turns training into behavior.
One of Europe's largest generative-AI leadership conferences. The inaugural SE Europe edition ran in Athens with speakers from OpenAI, Microsoft, Google, Stanford and Harvard.
100mentors is built for the awkward middle of AI adoption - past the excitement, before the results. Here is roughly what an organization gets out of it.
Run structured bootcamps that move employees from AI-curious to AI-capable, tailored to each department's real work.
Use Wiserwork to make recurring meetings shorter, clearer and actually strategic instead of a standing calendar tax.
Tap the GenAI Summit and leadership programs to align the people who decide budgets, not just the people who use tools.
Track adoption at the team level so "we're using AI now" becomes something you can point to rather than hope for.

Co-Founder & CEO. A graduate of AUEB, Ohio State and Columbia University - where he held research and fellowship roles at the Blinken European Institute - Nikoletakis is a Fulbright scholar who spent roughly seven and a half years in the United States.
He came home to Greece for compulsory military service and stayed to build 100mentors in 2015. The founding frustration was personal and simple: young people make once-in-a-lifetime decisions with almost no direct exposure to the paths in front of them. The fix was to make expertise reachable - the same instinct the company now applies to organizations navigating AI.

100mentors is an Athens-based company that helps organizations adopt generative AI - with people, not just tools, at the center. Founded in 2015 as an on-demand mentorship platform that connected 21,000+ students across 17 countries with 2,500+ mentors from top universities and companies, it pivoted with the rise of generative AI into an enterprise partner offering AI upskilling bootcamps (GenAI Academy), an AI-powered meeting tool (Wiserwork), and the GenAI Summit, positioned as one of Europe's largest generative-AI leadership conferences.
