Who Is Marko Oolo?

Marko Oolo is a business and investment professional from Estonia.

He became publicly known through his work with technology companies, his personal investment journey and his efforts to make financial knowledge easier to understand.

Unlike an investor who focuses on only one area, Oolo works across several connected fields. He helps young technology companies through venture capital, manages his own investments and develops financial tools for ordinary investors.

He has also shared lessons from his investment mistakes. This has made his public content useful to people who want a realistic understanding of risk, long-term planning and portfolio management.

Marko Oolo’s Education and Early Career

Oolo studied subjects connected with civil engineering, building management and economics at Tallinn University of Technology, commonly known as TalTech.

His formal education was not focused entirely on finance. However, the analytical and planning skills connected with engineering later became useful in technology and investment work.

He moved into the technology sector and joined TransferWise. The Estonian company created a simpler way for people and businesses to transfer money between countries.

At TransferWise, Oolo gained experience connected with data, product development, business growth and customer needs. The company later changed its name to Wise and became one of Estonia’s most recognised global technology businesses.

Working inside a fast-growing company helped him understand how technology products are created, tested and improved. This experience later supported his move into venture capital.

When Did Marko Oolo Start Investing?

Oolo began investing in 2014 with approximately €3,000 from selling his car.

He did not build his portfolio through one sudden deal. Instead, he invested regularly and followed a long-term plan.

His portfolio gradually expanded into different types of investments, including public shares, funds, property and private companies.

The main ideas connected with his investment approach include:

• Starting with a clear financial goal
• Investing consistently over many years
• Spreading money across different assets
• Keeping detailed portfolio records
• Studying risks before investing
• Learning from unsuccessful decisions
• Avoiding emotional buying and selling

Oolo has explained that investment success does not come only from finding a company whose value increases. Investors must also understand how much money they could lose and whether one investment has become too large within their portfolio.

Marko Oolo’s Investment Mistakes

One reason Oolo’s investment content attracts attention is that he also discusses mistakes.

He has described an early decision in which he placed a large part of his portfolio into a risky fund. The investment performed badly, and he lost most of the money placed in it.

The experience taught him several important lessons.

First, a well-known investor supporting a project does not guarantee that the project is safe. Second, placing too much money into one opportunity can create serious damage. Third, investors must complete their own research rather than depending only on other people’s opinions.

These lessons became part of Oolo’s wider message about responsible investing.

Joining Superangel

Oolo joined Superangel in 2018.

Superangel is a venture-capital firm that supports early-stage technology companies. It was created by entrepreneurs with experience in building and investing in start-ups.

As of July 2026, the official Superangel investment team page lists Marko Oolo as a General Partner.

A General Partner is a senior member of a venture-capital firm. The role can include:

• Finding promising companies
• Meeting founders
• Studying products and markets
• Reviewing investment risks
• Making funding decisions
• Helping companies develop
• Managing relationships with fund investors

Superangel focuses mainly on technology companies from Estonia, the Baltic region and the Nordic countries.

Its investment interests include artificial intelligence, robotics, mobility, energy, financial technology, data and digital infrastructure.

Oolo’s experience at TransferWise is valuable in this work because he understands technology companies from both sides. He has worked inside a growing technology business and now helps evaluate new companies as an investor.

His career can be compared with Joe Lonsdale’s technology investment journey. Both moved from building or working with technology companies into supporting new businesses through venture capital.

What Is Portfellow?

Portfellow is an investment portfolio-management platform founded by Marko Oolo and software engineer Taavi Ilves in 2024.

The idea came from a personal problem.

Oolo had tracked his investments through a self-created Excel spreadsheet for more than ten years. Ilves had also developed his own method for organising financial information.

Both systems required regular manual work. The available portfolio-management tools did not fully support all the assets they wanted to track.

They therefore decided to create Portfellow.

The platform is designed to combine different investments into one clear overview. It can help users monitor assets such as:

• Individual shares
• Index funds
• Bonds
• Loans
• Cash
• Property
• Private companies
• Cryptocurrency

Portfellow allows investors to see how their money is divided and how their portfolio changes over time.

This is important because people may own investments through several banks, brokers or platforms. Without a combined overview, it can become difficult to understand total performance and risk.

Why Portfellow Matters

Portfolio tracking is not only about watching whether an investment rises or falls.

A complete overview can help an investor answer important questions:

• Is too much money invested in one company?
• Is the portfolio balanced across different assets?
• Which investments are producing the strongest results?
• How has the complete portfolio changed over time?
• Is the investor following the original financial plan?

Portfellow turns Oolo’s personal tracking method into a product that other investors can use.

The company reported that more than 400 people used the service during its early development. This showed that many investors experienced the same difficulty with managing several asset types.

Oolo’s move from technology employee to investor and product founder is similar to Adam Balon’s business and investment career. Balon used his experience building Innocent Drinks to support other businesses, while Oolo uses his technology and investing experience to help founders and portfolio owners.

Marko Oolo and Financial Education

Oolo has spent more than a decade supporting financial education in Estonia.

He helped develop Investeerimisklubi, which means Investment Club. The community gives people opportunities to discuss investing, saving and personal finance.

He was also involved in creating InvesteerimisFestival, or Investment Festival. The event brings together investors, business founders, financial professionals and speakers.

These projects make investment information available outside banks and formal classrooms. People can learn through discussions, practical examples and the experiences of other investors.

Oolo has also been connected with:

• Financial education in schools
• The Off The Record investment publication
• Public speaking and investor events
• The Igavene Heategu charitable organisation
• Online financial-education content

His work does not suggest that every person should choose the same investments. Instead, it encourages people to understand their own goals, risks and financial decisions.

Investor of the Year 2024

Marko Oolo received Estonia’s Investor of the Year title in 2024.

The recognition was connected with Äripäev’s Investor Toomas conference and Estonia’s wider investment community.

Several parts of his work contributed to the recognition:

• Building a long-term investment portfolio
• Sharing practical investing lessons
• Discussing both successful and unsuccessful decisions
• Supporting investor education
• Helping develop investment communities
• Creating tools for clearer portfolio management

The award increased public interest in Oolo’s investment strategy and professional career.

Contributor to Financial Literacy 2025

In April 2025, Oolo was named a Contributor to Financial Literacy.

The recognition came from major Estonian financial and public institutions, including the Ministry of Finance, Eesti Pank, the Financial Supervision Authority and the Estonian Banking Association.

The organisers highlighted more than ten years of work connected with investment education.

They recognised his role in developing Investeerimisklubi, InvesteerimisFestival, school projects, charitable programmes and financial publications.

This award showed that his contribution was not limited to managing his own portfolio. His work had also helped improve public understanding of money and investing.

What Is Known About Marko Oolo’s Portfolio?

Oolo has publicly discussed the development of his personal investment portfolio.

In July 2024, Estonian business reporting placed its value at approximately €1.25 million after almost eleven years of investing.

This amount should be described as a publicly reported portfolio value, not as his complete net worth.

A portfolio figure does not show all parts of a person’s financial position. It may not include every business interest, debt, tax responsibility or private asset.

The figure is still useful because it shows how Oolo’s long-term investment strategy developed from his first €3,000 investment.

Marko Oolo’s Main Investment Lessons

Begin With a Purpose

Investors should understand why they are investing.

A clear purpose may include retirement, future financial security or building an additional source of income.

Think Long Term

Oolo’s portfolio developed over many years. His experience shows that meaningful financial growth usually requires patience.

Understand Every Investment

Investors should know how a company or fund works, why its value may grow and what could cause it to fail.

Control Risk

High returns are never guaranteed. Investors must consider how much money they can safely lose.

Diversify the Portfolio

Depending too heavily on one investment can create unnecessary danger. Holding different assets can reduce the effect of one poor result.

Track Performance Clearly

Good records help investors understand whether their decisions are working. This principle later became the main idea behind Portfellow.

Why Is Marko Oolo Important?

Marko Oolo is important because he connects several parts of modern investing.

At Superangel, he supports founders building early-stage technology companies. Through Portfellow, he helps investors understand different assets in one place. Through financial-education projects, he helps people learn about saving, investing and risk.

His public story is also practical.

He started investing with a relatively small amount, made mistakes, continued learning and gradually built a larger portfolio. He then used those experiences to develop products and educational projects.

This makes his work relevant to:

• First-time investors
• Experienced portfolio owners
• Technology entrepreneurs
• Start-up founders
• Financial-education students
• People interested in Baltic business
