Marko Oolo’s Early Life and Background
Marko Oolo was born in Estonia. He has kept details about his parents, siblings and childhood away from the media. There are no strong facts about his early schools, exact birthplace or wider family background. His journey did not begin with a senior finance role.

Education and Academic Training
TalTech – Tallinn University of Technology

Career at TransferWise
Marko Oolo joined TransferWise, now known as Wise, in September 2014. He worked there for about three and a half years during an important stage of the company’s growth.
Growth Analyst
From September 2014 to September 2016, he worked as a Growth Analyst with a focus on user experience. His duties included building datasets, studying customer behaviour and testing product changes. He used data tools, surveys and customer conversations to understand problems and test ideas. One of his key results was helping build a self-service system that reduced customer contact by half. This showed his ability to turn data into practical product improvements.
Product Manager
In September 2016, he became a Product Manager focused on user experience. He worked with engineers, designers, analysts and other product teams. His work included product strategy, customer journeys, service design and clearer communication. He stayed in the role until February 2018.
Building Investeerimisklubi
In November 2014, Marko helped create Investeerimisklubi with Tõnis-Denis Merkuljev. The group became one of the best-known investor communities in Estonia. It was built to make investing easier to understand and to connect people who wanted to improve their financial lives. The community grew to more than 15,000 members and organised over 250 finance events. Its events covered shares, property, start-ups, saving, risk and long-term wealth. He remained involved until November 2021. The community later joined Äripäev and became connected with Investor Toomas.
Founding InvesteerimisFestival
Marko also helped launch InvesteerimisFestival in 2015. He served as founder and chief executive until 2022.
A Leading Retail Investor Event
The festival developed into a three-day gathering for investors, entrepreneurs and finance experts. It attracted more than 2,000 people and became one of Europe’s largest retail investor events. The event helped strengthen Estonia’s culture of personal finance and business learning.
Growth and Acquisition
The festival grew year after year and later became part of Äripäev’s finance operations. This move gave it access to a larger media network and stronger event resources.
Marko Oolo at Superangel
Marko Oolo joined Superangel in February 2018. Superangel is an Estonian venture capital firm that supports early-stage technology companies.
Investment and Portfolio Manager
From February 2018 to January 2022, he worked as Investment and Portfolio Manager for Superangel One.

The fund often leads or co-leads early-stage rounds, with investments between €400,000 and €1 million.
Investment Style
His investment style combines numbers with founder quality. He studies the market, product, team, growth path and technical strength before making a decision. He values founders who learn fast, accept feedback and continue through difficult periods. During 2025, Superangel Two invested close to €11 million and added seven companies to its portfolio.
Portfellow and Portfolio Tracking
Marko Oolo began building Portfellow with Taavi Ilves in 2024. The platform was created to help investors follow their full portfolio in one place.
Why Portfellow Was Created
Many investors use spreadsheets, bank accounts and separate apps. This can make it hard to see total returns, asset balance and long-term progress. Portfellow helps users compare assets, measure growth and make decisions through data. Marko Oolo serves as a founder and Head of Product. His past work at Wise and Superangel gives him strong experience in digital products and investment management.
Company Launch
The business was established in 2024, while some social pages use January 2025 as the start of his formal co-founder title. The product launched in July 2024. An early company update said more than 400 people used the platform to manage portfolios with a combined value above €100 million.
Marathon Studios
In May 2019, Marko Oolo co-founded Marathon Studios in Tallinn. The company provided audio, video and image production services. Its work included podcasts, livestreams, event recordings, photography and business videos. He stayed as a co-founder until October 2023 and completed his exit that year. Some social pages use the name Epic Studios, but Marathon Studios is the name connected with his main career record.
Other Business and Social Projects
Igavene Heategu
Marko Oolo helped create Igavene Heategu with Randel Pärna. The charity follows a long-term model. It invests donated money and uses the returns to support good causes. The aim is to protect the original donations while creating long-term support. He has served on the board since 2016.
Off The Record Jutud
He also works with Taavi Ilves on Off The Record Jutud, a finance and business media project. Their discussions cover investing, markets and entrepreneurship. The project received the Investment Achievement of the Year honour in 2025.
Finantseesmärk
He is also linked with Finantseesmärk, a system that helps people turn financial goals into clear and measurable plans. The idea fits his belief that money goals should have a target, a time frame and regular review.
Marko Oolo’s Investment Journey
He began investing seriously in early 2014 with close to €3,000. His first steps included Baltic shares and peer-to-peer lending. Over time, he added start-ups, bonds, loans, property, exchange-traded funds and other assets. His portfolio later moved above €1 million through saving, investment returns and business income.
Lessons from Losses
His journey has included difficult periods. A fall in Wise’s share value once reduced his portfolio by more than €100,000 in one month. He treated the fall as a lesson in asset balance, patience and emotional control.
2025 Portfolio Results
In his 2025 review, he shared that the net value of his portfolio increased by 6.32 per cent. The investments returned 6.92 per cent, while he withdrew a net €11,265 during the year. Loans and bonds returned 9.90 per cent. Shares and exchange-traded funds returned 9.49 per cent. Property returned 8.33 per cent.

Social Media Presence
His main Instagram handle is @oolomarko. His bio describes him as an investor, financial education advocate and family man. In August 2026, the account had more than 6,700 followers. Follower totals change over time, so this number reflects that period.
Leadership Style and Core Beliefs
