Evidence over emotion
We invest by a systematic, research-grounded process — not hunches or headlines.
About
An independent firm,
built to manage money properly.
JonatanMars Invest is an independent investment firm, licensed and supervised by Slovenia's Securities Market Agency (ATVP). We exist to do one thing well: manage people's and companies' money for good risk-adjusted returns — transparently, and with a human on the other end.
Our story
Lessons, earned the hard way.
This team has built things together before — from the ground up, including the technology behind a regulated investment platform. We've made mistakes, learned the lessons, and earned our licences the hard way.
JonatanMars Invest is the firm those lessons led to: independent, disciplined, and deliberately transparent in a market that too often isn't. We made a clear choice to stand on our own — our own firm, our own platform, our own way of doing things — so that every decision we make is built around our clients, not around selling someone else's product.
What we believe
Four convictions.
Transparency is non-negotiable
Our fees and our methods are in the open. Clarity is a form of respect.
Sophistication should be accessible
The kind of management once reserved for the wealthy shouldn't require a fortune to access.
A human in the loop
Technology should free us to give better personal advice, not replace it.
Digital rails, human counsel.
Our approach in brief
A disciplined, factor-based investment process — with a machine-learning layer for our active strategy — delivered through a clean app and backed by a real advisor. We cover trading costs, manage with tax efficiency in mind, and report clearly.
Your assets are held in segregated accounts at our custodian, separate from the firm.
