Marko Oolo is an Estonian investor, entrepreneur and general partner at Superangel, a venture capital firm backing early-stage technology companies in the Baltics and Nordics. His influence extends beyond selecting startups: he co-founded investment-tracking platform Portfellow and helped establish initiatives that make investing more accessible to ordinary people.
In January 2024, Estonian business publication Äripäev named him Investor of the Year, while a national financial literacy award followed in 2025. His career links three areas often treated separately: building personal wealth, evaluating high-growth businesses and explaining financial decisions in public.
From his first investments in 2014 to his work with founders and investment communities, Oolo’s story offers a view of how Estonia’s technology and investing cultures have developed together.
Why Marko Oolo Has Become a Recognisable Name in Estonia
Oolo occupies an unusual position in Estonia’s financial landscape. He participates professionally in venture capital, develops a consumer finance product and discusses his own investing decisions with a broader audience. These activities connect the specialised world of startup funding with the practical concerns of people managing their savings.
His reputation rests on sustained activity across Superangel, Investeerimisklubi, InvesteerimisFestival and Off The Record Jutud. The common thread is measuring decisions and sharing the lessons.
Early-stage investing remains uncertain: careful assessment cannot prevent every loss. The systems Oolo uses and helps others build tell more than claims of financial success.
From Tartu and Engineering to a Different Career
Oolo says he was born and raised in Tartu, Estonia’s university city. He attended Tartu Commercial Gymnasium, completed military service with the Kuperjanov Battalion and subsequently studied at Tallinn University of Technology, also known as TalTech. His education included an exchange period in Lisbon, Portugal.
Construction provided his first professional direction. In an earlier interview about Investeerimisklubi, he described working in site and project management before deciding that the field was not where he wanted to build his future. His interest increasingly shifted towards entrepreneurship, investing and finance.
Engineering emphasises planning and execution; technology businesses demand these skills alongside experimentation. That combination later informed his work in fintech and investments.
The €3,000 Beginning and a Seven-Year Milestone
Oolo dates his deliberate investing journey to early 2014. In an account published by Portfellow, he explained that selling his car while living in Portugal provided roughly €3,000 in starting capital. His initial purchases included Baltic shares and peer-to-peer lending investments, rather than large stakes in private technology companies.
He has described increasing his investment contributions through employment income, saving and later business activity. Learning how to measure returns and keep records became part of the process. His account makes clear that portfolio growth was not solely about picking winning assets.
By 2021, according to his own disclosures, his investment portfolio had passed €1 million. That was a substantial personal milestone, but it was self-reported and does not establish a comparable return for anyone following similar habits. Contributions, market movements, investment risk and changes in asset values all affect such totals.
How Wise Opened the Door to Venture Capital
Before joining Superangel, Oolo worked at TransferWise, now called Wise, the international payments business founded in Estonia. His time in fintech exposed him to product development and the measurement of customer behaviour. He has described learning analytical tools, including SQL and statistics, alongside his professional responsibilities.
Young technology companies must establish demand, growth potential and the team’s responsiveness to evidence. Product experience helps assess those questions beyond financial forecasts.
When Superangel emerged in 2018, contemporary coverage identified Oolo as an investment manager and former early TransferWise employee. Superangel’s current team identifies him as a general partner. That progression places him within the firm’s investment leadership, rather than merely as an outside supporter of its portfolio companies.
Inside Superangel’s Early-Stage Investment Approach
Superangel invests in emerging technology businesses, with particular attention to the Baltic and Nordic regions. The firm’s portfolio has included names such as Bolt, Veriff, Starship Technologies and Montonio. These are investments associated with the firm; they should not automatically be interpreted as investments made personally by Oolo.
In a 2020 interview with investment platform Funderbeam, Oolo explained that he examined a founding team’s commitment, the potential market and what commercial success could look like. He described team, traction, technology, market and his own conviction as important considerations. His interest in international scalability also shaped the startup opportunities he discussed.
Unlike established listed businesses, startups may have little operating history and remain illiquid for years. Careful evaluation clarifies, but cannot eliminate, investment risk.
Bigger Funds, Wider Responsibilities
A significant development came in September 2024, when Superangel announced SEB pension funds as a key investor in its second fund. The firm said this would bring the fund’s investment capacity close to €40 million. Oolo publicly discussed the importance of institutional confidence in Baltic and Nordic innovation.
In his January 2026 review of the previous year, Oolo stated that Superangel Two invested nearly €11 million during 2025 and added seven companies. Those figures describe the fund’s activities, not his personal spending or earnings. They nevertheless show the scale of investment decisions connected with his professional role.
Portfellow: Turning a Spreadsheet Problem into a Business
Portfellow illustrates how Oolo’s personal investing experience developed into a software venture. He and fellow Estonian investor Taavi Ilves founded the company in 2024 after years of maintaining separate home-built systems for tracking portfolios. Oolo had relied on an Excel spreadsheet, while Ilves used a solution built around accounting software.
As their investments became more varied, maintaining those records required increasing effort. Portfellow was designed to bring assets such as shares, bonds, property and startup holdings into a clearer portfolio overview. The company identifies Oolo as founder and head of product, with Ilves responsible for technology.
The business says more than 400 investors used its platform within its first six months. That company-provided figure is not audited market-share evidence. Investors with several asset classes often struggle to assess exposure and returns using disconnected records.
Making Investment Education a Community Activity
One of Oolo’s earlier projects was Investeerimisklubi, an Estonian investment community he developed with Tõnis-Denis Merkuljev. A 2016 interview described gatherings in Tallinn and Tartu where participants examined companies, savings habits and investment decisions together. The emphasis was on learning through discussion and action rather than simply following financial personalities.
Oolo also helped initiate InvesteerimisFestival, which brings people together to discuss investing. These efforts predated some of his better-known business milestones and helped establish his connection with Estonia’s retail-investor community.
A further outlet is Off The Record Jutud, a publication and discussion project covering investments, business and personal finance. Oolo has described launching it with collaborators in 2023. Unlike a venture capital fund, its central product is analysis and conversation, giving audiences a way to understand decisions rather than participate directly in a startup deal.
His educational work has also extended to schools through the charitable initiative Igavene Heategu. That contribution was specifically acknowledged by Estonia’s Ministry of Finance when recognising his role in financial literacy.
Awards That Reflect More Than Investment Returns
Äripäev named Oolo Investor of the Year at its Investor Toomas conference in January 2024. The award established a clear public marker of his standing in Estonia’s investing community, alongside the events and educational projects with which he had been involved.
In 2025, Off The Record Jutud received an Investment Act of the Year distinction. The same year, Estonia’s Ministry of Finance recognised Oolo for more than a decade of contributions to financial literacy and investor education. The ministry highlighted his involvement with InvesteerimisFestival, publishing and school-focused initiatives.
These honours recognise education and community influence, not certified portfolio performance.
What His Portfolio Disclosures Reveal—and What They Do Not
Oolo has been relatively open about the composition of his investments. In a retrospective published by Portfellow, he gave an early-2023 allocation of 48% property, 19% venture capital, 16% loans, bonds and crowdfunding, 14% shares and index funds, and 3% cash or equivalents.
That breakdown is historical, not a current asset statement. It also illustrates concentration risks: property and private-company holdings cannot necessarily be sold quickly, while lending and crowdfunding involve different forms of credit risk. Diversification across categories does not make a portfolio immune to downturns.
His personal website has described an investment portfolio exceeding €1.5 million. However, portfolio value is not the same as total personal net worth. Liabilities, ownership arrangements, taxes and the valuation of illiquid assets matter. An independently verified figure for Oolo’s complete current net worth has not been established.
His Public Position in 2026
As of 2026, Superangel identifies Oolo as a general partner, while Portfellow identifies him as its head of product and co-founder. His continuing public activity includes investment commentary and financial education. In a published review dated January 2026, he reflected on the previous year’s Superangel investments, Portfellow development and personal portfolio results.
In that review, he disclosed a 6.92% investment return for 2025 and said his portfolio’s net value rose 6.32%, despite withdrawals. These were figures from his own records, not independently audited performance data. They illustrate why investment returns must be distinguished from cash contributions and withdrawals when assessing progress.
Oolo has also said he is the father of two sons and discusses financial planning for children. He has not made a comprehensive account of his private family life central to his professional work. His significance remains chiefly in the interaction between venture funding, practical financial tools and public investment education.
Conclusion
Marko Oolo’s career shows how Estonia’s fintech, startup and retail-investing communities can reinforce one another. Experience at Wise led into venture capital at Superangel; years of managing his own investments helped inspire Portfellow; and community projects brought financial discussions to a wider audience.
His documented achievements are most meaningful as evidence of sustained professional and educational work, not as a promise of effortless wealth.
