What If We Sold Our Data on Our Own Terms?

"If you’re not paying for the product, you are the product.". It’s a phrase we’ve all heard. And yet, most of us still happily use platforms like Google, Meta, or OpenAI without reaching for our wallets.

Because the deal seems fair. We get world-class tools:

Free search
Free email
Free storage
Free social media
Free AI assistants
Free productivity tools

In exchange, we give something less tangible: our data. But here’s the real question: Do we actually understand the deal we are making?

The collected data fuels targeted advertising, product optimization, AI training, and market intelligence. Sometimes it’s anonymized. Sometimes aggregated. But rarely transparent.

And here’s the paradox: Most people don’t object to giving up some privacy, as long as they get value in return.

The problem is not the exchange itself. The problem is the lack of transparency.

We don’t know:

Exactly what data is collected
How it is classified
Who it is shared with
What it is worth
How much revenue it generates

We accept the model because it’s convenient.

A few years ago, a small Belgian fintech, called Cake, gained attention with a bold idea: users would receive a monthly "share of the cake" - a small cash reward - in exchange for their financial data.

The app positioned itself as a Personal Finance Management tool. But the real innovation wasn’t the budgeting dashboards. It was the direct compensation for user data. Even if the amounts were modest (often just a few euros per month), the concept was powerful: data as dividend.

Cake has since discontinued its services. But the underlying idea remains fascinating and unfinished.

This use case raises a broader question: what if we stripped the model down completely?

No budgeting dashboards.
No "free" tools.
No hidden trade-offs.

Just this: You choose to sell your data and you get directly paid for it.

Could there be a market for a platform where:

You decide exactly which data is shared
You choose which companies can access it
You see the price before agreeing
You receive direct compensation
You can stop data sharing (and even delete your data) at any moment

A marketplace for personal data, but ethical, controlled, and transparent.

From a customer perspective, you could:

Register and provide personal, professional, or behavioral data
Upload receipts, invoices, or credit card statements
Grant Open Banking consent for financial data access
Complete surveys or A/B testing questionnaires
Allow optional geo-location or online behavior tracking

In return:

You see exactly what data is stored
You access analytics derived from your own profile
You define which companies can access which data (via a clear consent management module)
You see the price attached to every data-sharing action
You are credited immediately when you opt in

From a company perspective (i.e. traditional advertiser), you could:

Specify the data you need
Target specific customer profiles
Request raw or processed data
Launch surveys and questionnaires through the platform
Define how much you are willing to pay for access (supported by smart pricing mechanisms). But here is a big challenge. Platforms like Facebook don’t sell raw data. They sell targeted advertising powered by data. The value lies in Aggregation, Behavioral patterns, Machine learning insights and Predictive modeling. That makes it far from straightforward to translate the value of these insights into the value of the underlying data.

Instead of buying ad space based on opaque targeting logic, companies would directly source structured, consent-based data.

Most people already give away their data for free, in exchange for convenience.

So what happens if you offer:

Transparency
Control
Direct compensation

Even if it’s modest - €5, €10, €20 per month - would people prefer cash over "free" services? Or are we too accustomed to the illusion of free?

Maybe the real question isn’t whether such a platform is technically possible. It’s whether society is ready to acknowledge that personal data:

Has measurable economic value
Is already being monetized
Could be redistributed more fairly

Today, the data economy is dominated by large platforms.

Tomorrow, could it become a two-sided marketplace where individuals are not the product but the supplier?

Because the uncomfortable truth is this: We are already selling our data. The only difference is that we don’t see the invoice.

Transforming the insurance sector to an Open API Ecosystem

1. Introduction "Open" has recently become a new buzzword in the financial services industry, i.e. open data, open APIs, Open Banking, Open Insurance …, but what does this new buzzword really mean? "Open" refers to the capability of companies to expose their services to the outside world, so that external partners or even competitors can use these services to bring added value to their customers. This trend is made possible by the technological evolution of open APIs (Application Programming Interfaces), which are the digital ports making this communication possible. Together companies, interconnected through open APIs, form a true API ecosystem , offering best-of-breed customer experience, by combining the digital services offered by multiple companies. In the technology sector this evolution has been ongoing for multiple years (think about the travelling sector, allowing you to book any hotel online). An excelle...

RPA - The miracle solution for incumbent banks to bridge the automation gap with neo-banks?

Hypes and marketing buzz words are strongly present in the IT landscape. Often these are existing concepts, which have evolved technologically and are then renamed to a new term, as if it were a brand new technology or concept. If you want to understand and assess these new trends, it is important to reduce the concepts to their essence and compare them with existing technologies , e.g. Integration (middleware) software ensures that 2 separate applications or components can be integrated in an easy way. Of course, there is a huge evolution in the protocols, volumes of exchanged data, scalability, performance…, but in essence the problem remains the same. Nonetheless, there have been multiple terms for integration software such as ETL, ESB, EAI, SOA, Service Mesh… Data storage software ensures that data is stored in such a way that data is not lost and that there is some kind guaranteed consistency, maximum availability and scalability, easy retrieval...

IoT - Revolution or Evolution in the Financial Services Industry

1. The IoT hype We have all heard about the "Internet of Things" (IoT) as this revolutionary new technology, which will radically change our lives. But is it really such a revolution and will it really have an impact on the Financial Services Industry? To refresh our memory, the Internet of Things (IoT) refers to any object , which is able to collect data and communicate and share this information (like condition, geolocation…) over the internet . This communication will often occur between 2 objects (i.e. not involving any human), which is often referred to as Machine-to-Machine (M2M) communication. Well known examples are home thermostats, home security systems, fitness and health monitors, wearables… This all seems futuristic, but smartphones, tablets and smartwatches can also be considered as IoT devices. More importantly, beside these futuristic visions of IoT, the smartphone will most likely continue to be the cent...

A bank account - A concept of the past

Almost every recent article written about banking starts with the statement that the banking industry is being disrupted by new competitors, new innovations and new technologies. Although this statement is definitely true, the extend of the disruption can still be debated. Even the most innovative neo-banks still work with bank (current, saving, term and investment) accounts, cards (credit and debit), traditional credits, existing payment infrastructure… The user experience surrounding the origination and servicing of these products has dramatically improved (and will continue to evolve), but the underlying banking products are not really disrupted. You could argue that banking products are so intertwined with society and our way of thinking about finance, that they can’t be disrupted, but looking at those products you cannot ignore that they are far from an optimal solution in our current digital world. Let’s consider cards for example. Isn’t ...

AI in Financial Services - A buzzword that is here to stay!

In a few of my most recent blogs I tried to demystify some of the buzzwords (like blockchain, Low- and No-Code platforms, RPA…), which are commonly used in the financial services industry. These buzzwords often entail interesting innovations, but contrary to their promise, they are not silver bullets solving any problem. Another such buzzword is AI (or also referred to as Machine Learning, Deep Learning, Enforced Learning… - the difference between those terms put aside). Again this term is also seriously hyped, creating unrealistic expectations, but contrary to many other buzzwords, this is something I truly believe will have a much larger impact on the financial services industry than many other buzzwords. This opinion is backed by a study of McKinsey and PWC indicating that 72% of company leaders consider that AI will be the most competitive advantage of the future and that this technology will be the most disruptive force in the decades to come. Deep Lea...

An overview of 1-year blogging

Last week I published my 60th post on my blog called Bankloch (a reference to "Banking" and my family name). The past year, I have published a blog on a weekly basis, providing my humble personal vision on the topics of Fintech, IT software delivery and mobility. This blogging has mainly been a personal enrichment , as it forced me to dive deep into a number of different topics, not only in researching for content, but also in trying to identify trends, innovations and patterns into these topics. Furthermore it allowed me to have several very interesting conversations and discussions with passionate colleagues in the financial industry and to get more insights into the wonderful world of blogging and more general of digital marketing, exploring subjects and tools like: Search Engine Optimization (SEO) LinkedIn post optimization Google Search Console Google AdWorks Google Blogger Thinker360 Finextra … Clearly it is not easy to get the necessary ...

From app to super-app to personal assistant

In July of this year, KBC bank (the 2nd largest bank in Belgium) surprised many people, including many of us working in the banking industry, with their announcement that they bought the rights to broadcast the highlights of soccer matches in Belgium via their mobile app (a service called "Goal alert"). The days following this announcement the news was filled with experts, some of them categorizing it as a brilliant move, others claiming that KBC should better focus on its core mission. Independent of whether it is a good or bad strategic decision (the future will tell), it is clearly part of a much larger strategy of KBC to convert their banking app into a super-app (all-in-one app) . Today you can already buy mobility tickets and cinema tickets and use other third-party services (like Monizze, eBox, PayPal…) within the KBC app. Furthermore, end of last year, KBC announced opening up their app also to non-customers allowing them to also use these thi...

Marketplaces in the financial industry - Here to stay?

Marketplaces are hip and trendy on the internet and will likely evolve even more in the near future. In some markets (like food delivery, transportation, commerce, holiday…) they already represent double digit market shares (e.g. in 2018 $1.86 trillion was spent globally on the top 100 online marketplaces), but for the financial services sector, their impact (even though there are a few unicorn FinTechs in this space) on the industry is still limited. Any form of intermediation (travel agents, taxi dispatchers…) will likely be replaced by a modern, digital and more direct equivalent, i.e. a digital marketplace. As the business of banks is exactly the intermediation between people having excess money and people needing money, the financial services sector will be significantly impacted. Furthermore, marketplaces are strongly intertwined with other concepts like the gig-economy, the sharing-economy and the API-economy . All these trends will ultimately...

Neobanks should find their niche to improve their profitability

The last 5 years dozens of so-called neo- or challenger banks (according to Exton Consulting 256 neobanks are in circulation today) have disrupted the banking landscape, by offering a fully digitized (cfr. "tech companies with a banking license"), very customer-centric, simple and fluent (e.g. possibility to become client and open an account in a few clicks) and low-cost product and service offering. While several of them are already valued at billions of euros (like Revolut, Monzo, Chime, N26, NuBank…), very few of them are expected to be profitable in the coming years and even less are already profitable today (Accenture research shows that the average UK neobank loses $11 per user yearly). These challenger banks are typically confronted with increasing costs, while the margins generated per customer remain low (e.g. due to the offering of free products and services or above market-level saving account interest rates). While it’s obvious that disrupting the financial ma...

Peer-to-peer payments - A crucial component towards a cashless society

The Corona crisis has led to an exponential decrease in the usage of cash , due to the associated hygienic problems and the enormous rise of eCommerce. While in commercial transactions cash is disappearing rapidly, it is however still commonly used for informal money exchanges , like between friends, family, colleagues…, but also those payments are becoming more and more digital, thanks to peer-to-peer payment (P2P) solutions . These solutions drastically improve the user experience (removing friction) for both the person initiating the payment (= the payer) and the person receiving the payment (= the recipient), compared to a simple initiation of a wire transfer in a banking app. Before clarifying where those solutions bring most value, it is important to first identify the typical use cases , where peer-to-peer payments are most common, as the P2P payment solutions need to optimally accommodate these use cases: Family giving a cash gif...
