REVOLUT BANKS ON EXASOL FOR ENTERPRISE-WIDE ANALYTICS SOLUTION

Exasol provides fast-growing Fintech business 100x faster data queries, enabling self-serve data analytics for all employees across business functions
Digital banking alternative, Revolut, has selected Exasol’s in-memory database as the central data repository for its organisation-wide data analytics requirements. One of the fastest growing FinTech businesses in the world, Revolut has adopted data-driven decision making, and has chosen Exasol to provide comprehensive and up to date data to every employee from its data science team to business heads to frontline staff.
Revolut previously used Postgres, but it was not feasible to use the transactional database when computing complex aggregations with multiple joins across hundreds of millions of rows of data. Revolut’s data science team sought a high performance Online Analytical Processing (OLAP) database and trialled a free Docker image of Exasol. It was impressed that even the limited version of the database, running on a single node, outperformed its former database. Furthermore, since the trial began in May, Exasol has never failed to perform or required maintenance.
An Exasol cluster is now fully implemented in production on the Google Cloud Platform, providing the central repository for all data required for analytics throughout the business. Since implementation, the database has improved decision-making processes with query times that the data scientists estimate are 100 times faster than its previous solution. With more than 2 million people using the Revolut app, the ability to use and analyse large datasets spanning several sources helps Revolut with fraud detection, improving customer satisfaction and financial reporting.
Abhi Thanendran, lead data scientist at Revolut, said: “Revolut is extremely data-driven, and we needed a universal database that could keep up. When we tested Exasol in the Docker trial, to say we were extremely impressed would be an understatement.”
Thanendran continued: “We’ve saved countless hours across all our departments. Reports that previously took hours to generate can now be loaded in a second, and we have a much better grasp of our company KPIs and industry trends. It’s also proved incredibly stable since the start and we’re looking forward to seeing continued results as we increase the demands we place upon the database.”
Unusually, Revolut provides every employee with an open source BI (Business Intelligence) tool, and self-service access to the central Exasol repository. This data underpins the key performance indicators (KPIs) for every team. The data science team also works from this central database as a “single point of truth”, and benefits from being able to quickly query and download extracts from the large live database at any time. Exasol has saved Revolut’s data scientists a significant number of hours work during ETL (Extract, Transform and Load) processing, which enables them to run their further analysis in proprietary tools and use advanced functionality such as machine learning algorithms for analysis.
Aaron Auld, CEO, Exasol, commented: “Revolut is a high-growth, cutting-edge business that has put data at the heart of its culture by overcoming the limitations of conventional data analytics solutions. Its data science team has very ambitious plans for the future and we are excited about working with them to make full use of Exasol’s capabilities to apply machine learning tools to its processes and empower employees with the data analysis capabilities they need.”
Revolut was the latest British financial technology company to achieve “unicorn” status in April 2018 when a new funding round valued the business above $1 billion. The company has an ambitious roadmap with a high rate of future product releases that will create new data sources. Having adopted Exasol’s flexible data analytics infrastructure, it can easily aggregate these into its central repository by expanding its database schemas, ensuring employees continue to have access to the all data they need as business grows.

SEIZING THE OPEN BANKING OPPORTUNITY

Nick Maynard is a Lead Analyst at Juniper Research
Open Banking has made significant progress in 2020, having recently launched across much of Europe and now starting to emerge in other markets too. And there are two primary reasons why Open Banking is disrupting the banking industry so much:
- Banks have begun to discover the real competitive advantage of a more open approach to banking. Offering a superior Open Banking experience to customers can be a compelling differentiator from other competitors as part of a wider digital app experience. Open Banking also creates a level playing field in markets where regulatory intervention has led to Open Banking deployment. As all banks are required to deploy APIs in this scenario, the situation is the same and does not put any one particular bank at a disadvantage.
- Legislation – for example, in October 2015, the European Parliament adopted PSD2 (the revised Payment Services Directive). By early 2020, major banks in the EU had adopted Open APIs. There have however been many cases of late deployments of APIs and problems with the availability of APIs.

Nick Maynard
The Disruption Factor
Open Banking is a major disruptive factor for banks. The reason for this being that it opens up account data to both AISPs (Account Information Service Providers) and PISPs (Payment Initiation Service Providers), which can attempt to carve out a role in the banking area.
- AISPs: These new vendors are able to access transaction data and balance information, as well as related information. This has, in particular, led to the rise of vendors such as Emma, Yolt and Connected Money. These vendors combine information from multiple sources, adding value to the user.
- PISPs: In this case, the vendors are able to leverage Open Banking API connections to initiate payments directly from the bank accounts in question. This means that these players are able to bypass traditional payment methods, such as cards. Vendors such as American Express and PayPal have already launched solutions that have taken full advantage of this action.
PSD2 Changes
Generally, the implementation of the new PSD2 European regulation for electronic payment services effectively reduces the entry barriers for new digital players. It also opens up banks to the potential for competition, enabled by their own APIs. This allows these players to compete with existing services in fields currently offered by the banks. In the case of AISPs, it is possible that third-party applications could displace the role of the apps from incumbent players, which would dilute the bank’s relationship with their users.
As with any fundamental change to markets in the banking area, there is the potential to bring a number of both opportunities and challenges to consider with Open Banking.
Open Banking Opportunities & Challenges to Consider
Source: Juniper Research
Banks and other parties that are looking to become involved in the Open Banking ecosystem must weigh these opportunities and challenges carefully. Open Banking certainly needs a more collaborative approach than traditional banking models, which will require significant effort to make them successful.
The Forecast for Open Banking
The total number of Open Banking users is set to double between 2019 and 2021, reaching 40 million in 2021 from 18 million in 2019. The ongoing Coronavirus pandemic is increasing the need for consumers to have the clarity of combining their accounts and gaining insight on their financial health, and also boosting momentum in the adoption of Open Banking.
This extraordinary growth is being driven by Europe, where the regulator-led approach to Open Banking has created a standardised market, with low barriers to entry. This contrasts with markets like the US, where a lack of central regulatory intervention is limiting growth potential.
Open Banking – Delivering Opportunities and Threats
It is worth noting that Open Banking can be both a threat and an opportunity for traditional banks. While Open Banking exposes user information and access to potential competitors, this threat has the potential to affect all players in the market equally. Consequently, established banks must create innovative Open Banking services that will provide benefits for the user, while also attracting customers from less innovative competitors.
Payments will be critical to the emerging Open Banking ecosystem; accounting for over $9 billion in transaction value in 2024. However, payments in this ecosystem are at a particularly early stage. While eCommerce is dominated by card networks, there is the potential that this role will be eroded over time by ‘direct from account’ payments. Consequently, card networks should look to offer Open Banking-enabled payment services, in order to offset the risk of future disruption.

2021: THE NEW-NORMAL LIFECYCLE FOR BANKING

Laura Crozier, Global Director of Industry Solutions, Financial Services at Software AG
It would be impossible to talk about predictions for the banking industry in 2021 without mentioning the cataclysmic impact that 2020 and the pandemic has had on people, businesses and countries.
Unlike with the global financial crisis, banks have been able to step up as “good guys” this time around, rebuilding their reputations as well as accelerating digital transformation. One of the main outcomes is increasingly smart, efficient online payments.
In 2020, the banking industry innovated like never before. This is the new normal. Overall, customers and society will be the beneficiaries from the changing industry. Here are my predictions:
Reputations are reborn
Banks across the globe pulled out the stops to integrate and adapt systems and processes to help customers during the pandemic. They offered accommodations in loans, assisted governments with the distribution of financial relief, and supported consumers by upping contactless spending limits and virtual deposits.
In 2021, banks will risk losing that rosy glow as economic circumstances drive them to deal with non-performing loans, mortgage foreclosures, layoffs etc. But, beyond their role in society as providers of capital and liquidity, banks will invest to sustain their reputations as trusted and good corporate citizens and use their power to persuade their customers and providers to adopt higher environmental and ethical standards. This will be in the areas of bank carbon-neutrality, sustainable financing, serving the unbanked, diversity and gender equality (as the number of women running a major global bank will double from one (Jane Fraser at Citi) to two). It’s a start.
Coming of age in the way of working
Back in Q1, when bank employees cranked up their laptops on their dining room tables, banks that were strategically undertaking business transformation accelerated their efforts. Those that were tactical, or on the fence, now understand with painful clarity that this work must be undertaken strategically.
Cracks in process and the way of working and their resulting risks can be crippling. Especially from a back-office perspective, it is not enough to rely on “organisational memory” and collegial proximity for work to get done right. Advanced banks pushed the boundaries of remote work, and the proof of concept was successful. So, they’re doubling down on developing digital twins and moving to the cloud. They’re adopting the hybrid office/WFH approach to reduce health risks and reduce cost permanently. The watercooler will never be the same.
The death of cash
Ok, maybe the rumours of the death of cash are a bit exaggerated since there will always be the need for cash (and, to some extent checks; the USA, for example, cannot seem to live without them). But the pandemic has permanently changed the way that consumers and small businesses bank, and the demotion of cash has been accelerated by a decade by the pandemic. For example, the Norwegian central bank said that cash payments in that country have plummeted to just 4% of transactions since March.
Implications? It will be critical to continue evolving payments to be smart, safe and flexible to compete in new world, in both retail and commercial banking. Also, the permanent change in the mix of channels will see banks’ face-to-face engagement with customers fade. Branches aren’t going to go away entirely, but they will be reserved for high value activities – by appointment only. To compensate, the personal touch has to be delivered digitally and intelligently.
The role of the bank as a “financial wellness partner” is being born. Banks will use customers’ data, not just to personalise and differentiate banking experiences, but to make recommendations for products and services beyond traditional banking from across their ecosystem to serve their customers well. Just as customers own their cash (physical or digital), in the future they will demand that they own their data (and can share it with whom they choose). Then retail and commercial clients will share their data in return for value.
