Analysis of Common Data Challenges in Fintech Development

A quick analysis with real-world examples and solutions to improve data management and platform success.

A review of B2B client interactions spanning the last 7 years has uncovered frequent data-related issues in Fintech development. These findings are vital for developers, emphasizing opportunities for enhancement and reinforcing the significance of precise and dependable data as a key competitive advantage.
Below are 10 Common Data Mistakes in Fintech Development.

The Illusion of Free Data

Problem: Many developers mistakenly believe that free data sources are the most cost-efficient option, but hidden costs arise due to frequent quality issues, which can consume significant time and effort to correct. This leads to a major decrease in development efficiency.
Example: A solo entrepreneur creating a stock screener ended up spending up to two hours a day fixing errors from a free data source, drastically slowing down his progress.

Unreliable Data: Damaging User Confidence

Problem: Using data from untrustworthy sources can negatively impact user confidence, as accurate data is essential for decision-making in fintech.
Example: A wealth management platform opted for a cheaper data provider, but it resulted in security price discrepancies. This caused 20% of the users to leave, as they no longer trusted the platform’s analytics.

Limited Market Coverage: Restricting Growth

Problem: Startups that aim for scalability need data providers with a wide market range. Switching providers as the business grows is time-consuming and costly, potentially slowing growth.
Example: A European fintech startup had to pause its expansion efforts for three months while integrating a new provider for Australian-traded securities, leading to user dissatisfaction and churn.

Ignoring Licensing Terms: Legal and Operational Risks

Problem: Overlooking the importance of data licensing can lead to severe legal challenges and operational interruptions.
Example: An investment app displayed delayed stock prices without securing a redistribution license, leading to legal complications that caused it to lose support for key securities.

Outdated Providers: Stalling Innovation

Problem: Relying on outdated data providers can slow down a company’s ability to innovate and adapt quickly — especially critical for fintech startups.
Example: A U.S. asset management firm faced costly delays while trying to renegotiate terms with a traditional provider. Eventually, they moved to a more agile data service to meet their evolving needs.

Single Data Source Dependency: Risking Accuracy

Problem: Depending on a single source for financial data can lead to calculation errors and inaccurate investment decisions, which can harm performance.
Example: An asset management firm experienced a $10,000 loss due to outdated stock prices from a sole provider. They mitigated future risks by onboarding a secondary provider to cross-verify data.

Over-Investing in Premium Data Providers

Problem: Jumping straight to a high-end data provider can consume too much of the budget, leaving little for other essential areas like development or marketing.
Example: A fintech startup switched from an expensive data vendor to a more affordable alternative, freeing up much-needed resources for product development and customer acquisition.

Inadequate Historical Data Coverage

Problem: A lack of extensive historical data, including delisted stocks, can lead to errors in backtesting and flawed strategies.
Example: An investment firm saw more accurate backtesting results after extending its data to include a wider range of historical data and delisted stocks.

Fragmented Data Sources: Increasing Costs and Complexity

Problem: Relying on multiple data providers for various feeds can lead to extra costs and operational inefficiency. Often, sticking with a single provider is more cost-effective.
Example: A financial services company realized savings and simplified its data management by consolidating all its data services under one provider instead of subscribing to multiple feeds.

Ignoring API Rate Limits: Causing Service Interruptions

Problem: Exceeding API rate limits during high-traffic periods can lead to unexpected outages and slow updates.
Example: A fintech platform experienced severe delays and disruptions during a market surge due to API rate limit breaches, which they later resolved by improving their monitoring and adjusting their usage strategy.

Conclusion

In fintech development, data accuracy, quality, and accessibility are paramount for building successful platforms. The recurring data-related issues highlighted here reveal that developers often underestimate the importance of choosing the right data provider and managing their data effectively. Mistakes such as relying on free or untrustworthy sources, not planning for market expansion, or failing to secure the appropriate licenses can have long-term consequences.
