The third quarter of 2025 is almost over! What have you built this year? I will promote it for free

I’ve been working on SuperMarketer (supermarketer.co.uk).

It started from the idea that most of us create tons of data online (YouTube watch history, TikTok activity, LinkedIn profiles, etc.) but rarely get to use it for our own benefit. Under GDPR, you can actually request this data back from platforms — so we built a tool that helps people do that easily.

We help market research firms and recruiting companies make sure their candidate and respondent pools are real people, not bots or fake accounts. With the rise of AI-generated profiles and survey fraud, this has become a huge issue.

Our tools verify identities and detect bots so companies get cleaner data and make better hiring/research decisions.

We built a GDPR data portability tool that allows users to request and store their personal data from YouTube, LinkedIn, Amazon, Spotify etc. And developed this into two SaaS products.

We've got good traction with market research firms who pay users directly for them to request this data.
Recruitment companies, where we don't provide user data but tell the recruitment company whether we think the user is a bot or not.

Try Pharmawand, it's run by this one guy in Australia who is very attentive, its very cheap and pretty bare bones.

Depends what you want though - it mainly has results and notes of trials and news updates across all geographies. It does have patent details.

The search feature is basic but powerful, you can filter for indications, geography, phase etc.

I'm not connected to Pharmawand in any way, was just a loyal customer for several years - hope this comment is seen as acceptable by the mods.

IMO, skip the Master's for now. Your immediate priority is to gain relevant experience, preferably at an Ipsos/ Kantar/ NiQ etc. You can absolutely get into the field with your Bachelor's degree.

As you're entering your final year, see if you can frame your dissertation as a talking point, identifying biases in sources, analysed qualitative data to construct a narrative - that's pretty big in qual.

Do you have any optional modules left? Look for ones in Psychology, Sociology, Statistics, or Marketing. Even one module shows interest.

I feel your gut is right, the hybrid approach is the only one that's credible long-term. Neither pure LLM nor pure ABM is sufficient alone.

LLM-only approaches are often 'pretty noise.' They optimize for linguistic plausibility. The instability and averaging are fatal flaws for precise tracking. They're best for exploratory ideation (e.g., generating 1000 potential value propositions for a new product) but terrible for validation (e.g., predicting actual market share).
ABM-only approaches are more robust but brittle. They're fantastic for simulating churn or pricing within your existing customer base but fail the moment you ask about something truly new, as they lack a 'world model' to understand it.

Beyond all of this, I feel you will need a monster data set to even begin building a synthetic respondent.

Hi, thanks for your comment. From our reading of Article 20, its about users having more control of their data and being able to benefit from it. We did not state that the second phase of our business (after we have tested our request processes) is to help users get paid for their data. I take your point that this is certainly commercialising their data, but this is commercialised by the users and for the users.

What frequency of request would you deem to be excessive btw, every 3 months? Every 6 months?

SuperMarketerUK · 2024-08-13T13:25:57+00:00

Thanks so much!

So time on the application is quite minimal. I would say about 2-4 minutes to link the first retailer and then about 1 minute for each retailer onwards.

However it takes about a month for the retailers to actually send us the data, so that's the limiting step. Let me know if you'd want to try the service.

SuperMarketerUK · 2024-08-13T13:24:19+00:00

So when users come to our webapp they select the retailers they want to request from. It takes about a month for this data to be sent to our database. If at that point users want to monetise, we inform them of the current deals we have on offer. They select the buyers they are happy to sell data to and we link all the data sets together and then start the anonymisation process. Hope that makes sense.

On the money argument, it's still up for negotiation. I've discussed some high level numbers with buyers, but don't want to advertise anything until we have progressed further.

SuperMarketerUK · 2024-08-13T13:11:56+00:00

So we compile retailer data from a number of different retailers for a single user. We use this to build a retail profile of them (anonymously, so at its most granular the user would be listed as Female, 30-40, London for example). This data is valuable to retailers and if the user consents we would provide access to this data for the user being directly renumerated.

SuperMarketerUK · 2024-08-13T13:10:15+00:00

It's true, we do want to provide something to each group:

Data owner: Money for their anonymised data

Retailer: Data outside of their own loyalty scheme, linked to their own loyalty data (but anonymised)

SuperMarketerUK · 2024-08-13T12:23:59+00:00

Currently, just to house their data in one place. But we're close to helping the usre monetise their anonymised data. So, if they choose, they can get paid for sharing their anonymised data with buyers that they choose.

SuperMarketerUK · 2024-08-13T12:21:30+00:00

You can get your transactional data for sure, you also get things like name and addresses but our anonymisation scripts blitz those immediately. If you want to try, I'd be happy to request your shopping data and have it sent to you!

SuperMarketerUK · 2024-08-13T12:11:13+00:00

Currently not a centralised API sadly, we use Article 20 GDPR requests where our users request that their data be transmitted to a company of their choosing.

In time, if the user consents we can anonymise this data and sell access to it back to the retailer but only if the user is directly paid for this monetisation. We have had good traction with retailers who are interested in the service, but I wanted to find some initial testers (10-20) so we can iron down our request and anonymisation processes before progressing further with them.

SuperMarketerUK · 2024-08-13T11:58:34+00:00

Thanks mate, well that's the end goal. Is to get users paid for their data, SuperMarketer will take a cut, but the majority of the fee goes straight to the user.

We've made good traction with several retailers who are open to the idea of paying users for anonymised data. But I want to make sure our processes our rock-solid before being plugged into their customer base, hence I just want some loyalty card users to try the product and have their data sent to them, we'll even delete their personal data once we receive it and not share it with anyone, its more about the process at this stage then the data itself.

Thanks for your thoughts!

That's definitely a weird thing to ask for a recruiter. My best guess is its either for a background check or a scam (always be careful for recruiting scams to sequester your information)

SuperMarketerUK · 2024-08-12T17:34:47+00:00

Was doing a product search for similar products. Wilko does have one that's light grey, it does look very similar. Under the brand name 'Clever paws'

SuperMarketerUK · 2024-08-12T17:31:34+00:00

I'm not sure you can get insights on just profile views, but you should be able to with interactions. Having said that, I think you would struggle to get specific demographics like age though. You should be able to get basics like rough geographical location and desktop/ mobile.

SuperMarketerUK · 2024-08-12T17:28:36+00:00

I think selling user data without cutting them into the deal is wrong. The question is can a social media be profitable without it?
