From a spreadsheet replacement idea to serving users across multiple countries and 70+ currencies – discover how Exirio leveraged EODHD’s reliable financial data to create a truly global wealth management platform.
When Piero Politeo and his co-founder David Martínez de Lecea started working on Exirio back in 2020 lockdown, they had a simple yet powerful realization: “We ended up all of us having monster spreadsheets that over time became completely impossible to understand for anyone but the author.” What began as a solution to replace unwieldy spreadsheets has evolved into a comprehensive wealth tracking app serving users globally with EODHD powering their global data infrastructure.

Beyond Portfolio Tracking: Building for Global Complexity
“We don’t call ourselves a portfolio tracker because we don’t just allow tracking of security portfolios, but wealth,” explains Piero. “It could be properties, rare wine, watches, cars, land, you name it, crypto.”
Unlike geography-focused competitors, Exirio made a strategic decision from day one to embrace maximum currency flexibility. This architectural choice became their key differentiator, especially when paired with comprehensive global market coverage.
“If you come up with a currency that we don’t have, it will be fully available within two hours,” Piero notes. This flexibility proved crucial when serving expats and self-directed investors who hold assets across multiple jurisdictions.
The Romanian Breakthrough: When Speed Meets Global Data
The power of Exirio’s approach became dramatically apparent during their “Romanian breakthrough.” When a user requested Romanian Leu support, Piero added it within 24 hours. The user turned out to be a Romanian influencer who created a viral 30-minute video showcasing Exirio’s responsiveness.
But this overnight success created an immediate challenge: Romanian investors wanted to track Romanian stocks. “Every time you add a currency, you’re bound to have investors investing in local stocks. Which means, who is going to give you prices of stocks on the Bucharest Stock Exchange?” This search led them directly to EODHD.
“We started looking for who in the world was actually tracking and providing prices for Romanian stocks,” Piero explains. “And there you are – you came up. We reviewed it, decided to go with it, and never had any reason to look for an alternative solution.”
The Data Foundation: Beyond Basic Prices
For Exirio, reliable financial data serves two critical functions that set them apart from simpler portfolio tracking apps. Beyond accurate pricing, they use this data to calculate sophisticated metrics like Internal Rate of Return (IRR) and Time-Weighted Return (TWR) – analytics typically only available through professional wealth managers.
“Our closest competitors give you current value and your total gain – which doesn’t tell you which investments are actually performing better,” Piero explains. From EODHD, Exirio leverages:
- End-Of-Day Historical API for global markets – the foundation for all valuations
- Splits and dividends API – crucial for accurate historical calculations
- Live (delayed) API – for real-time portfolio updates
- Fundamentals API – for geographic and sector classifications
“The single most important element we depend on is yesterday’s closing prices,” Piero emphasizes. “And then the accuracy of split information – if any split data is wrong, everything goes exponentially wrong.”
Partnership That Understands Startups
Beyond technical capabilities, Piero highlights why the right partnership approach matters for startups: “When you’re not properly funded, every dollar counts. There are companies that profess to be supportive of startups, but when it comes to pricing structure, it’s ‘take it or leave it.’ EODHD has been very understanding with our situation.”
The responsiveness extends to technical support. “I know from direct experience that support requests are answered within hours. Send an email today, get an answer certainly today, probably within an hour or two.”
Results: Global Scale with Reliable Infrastructure
With reliable data infrastructure supporting their operations, Exirio has achieved global reach with support for 70+ currencies. Their sophisticated analytics, powered by accurate historical data, have become a key differentiator in the wealth tracking space.
Romania remains one of their highest market penetration countries, demonstrating how responsive customer service combined with comprehensive data coverage can create significant competitive advantages in specific regions.
Key Lessons for Fintech Startups
Exirio’s journey offers several insights for other fintech startups:
Choose Data Partners Carefully: “We never had any reason to look for an alternative,” Piero notes, emphasizing how the right data partner enables focus on core product development.
Architecture Decisions Matter Early: Building for global flexibility from day one, supported by comprehensive market coverage, allows rapid expansion into new markets.
User Feedback Drives Everything: “Our product is entirely developed based on user feedback,” while reliable data infrastructure ensures they can quickly implement new features.
Customer Service Creates Growth: Exceptional responsiveness, enabled by reliable partners, can generate viral marketing that money can’t buy.
Looking Forward
As Exirio continues scaling globally, their foundation of currency flexibility and comprehensive data coverage positions them for continued growth. “We release new versions every week with new exchanges and features,” Piero explains, “and reliable infrastructure lets us focus on what users actually want.”
With the complexity of global financial data handled by trusted partners, Exirio can concentrate on building tools that help individual investors manage wealth with institutional-grade sophistication.
