Buying data has always felt like gambling with your budget—and your compliance. Endless email chains, delayed counts, unreliable sources, and GDPR risk lurking in every spreadsheet. For years, the industry standard has been slow, risky, and almost entirely based on trust. But TheDataSupermarket (TDS) is rewriting the rules.

The Broken Model of Traditional Data Buying

Let’s be honest: the traditional method of buying leads or datasets is painful. You:

  • Speak to 3–5 sellers just to get quotes
  • Wait hours (or days) for lead counts
  • Share suppression files manually
  • Hope the seller is compliant
  • Often don’t get what you paid for
And if something goes wrong? Good luck getting a refund. TDS looked at this and said: “There has to be a better way.”

How The Data Supermarket Flips the Model

TDS doesn’t just digitise the process—it reinvents it. Here’s how:

Instant, Transparent Lead Search

No more back-and-forth. Buyers can search real-time lead counts across multiple sellers, filter by consent, industry, location, and more—and buy in seconds.

Real-Time Suppression File Matching

TDS automatically suppresses against every suppression file uploaded. That means no duplicates, no cross-seller collisions, and no risk of calling someone twice. This is done directly on each product page using the DupeCheck button—providing sub-3-second suppression validation in real time.

Compliance Built In (Not Bolted On)

Every seller on TDS must pass a rigorous Due Diligence process and upload proof of consent. And every download is linked to a DD Code—your unique audit trail if you're ever challenged.

PayPal Protection + Instant Refunds

TDS governs the entire payment process—built on top of PayPal’s secure infrastructure. That means we handle the authorisation, capture, and distribution of payments, including complex payment splits between multiple sellers. Sellers are only paid after the buyer’s 7-day dispute policy expires, ensuring full delivery satisfaction. Refund decisions are made by TDS based on clear evidence and buyer protection policies. This layered control ensures both speed and security, backed by the world's most trusted payment network.

DSAR Readiness in One Click

When a subject access request comes in, TDS generates a full DSAR Pack in seconds—automatically compiling all required documentation. Buyers stay protected, and sellers benefit from a centralised automated system that supports fast, compliant responses without manual overhead.

Instant ICO-Grade Due Diligence & Traceability

The TDS Due Diligence (DD) API and DSAR system directly align with the ICO’s 6 core expectations for due diligence and traceability. Unlike traditional manual processes, TDS automates the whole process instantly. This means every download comes with built-in documentation to prove compliance—not just for internal audits but if challenged by regulators. And it all happens in seconds, not weeks.

Weekly Forecasting with 7-Day Lead Availability

TDS helps marketers plan smarter—not just reactively. Our system uses real-time stock movement, historical upload patterns, and live reservation logic to forecast lead availability over the next 7 days—even for leads that haven't been generated yet. 

Because many sellers upload historical lead data, TDS learns from past volumes, delivery pacing, and daily performance to model future stock. Combined with buyer-selected criteria (e.g. Electric spend, build type, debt amount), this allows us to show what's likely to be available—with pinpoint accuracy. 

This forward-looking availability dashboard lets you optimise delivery schedules, avoid shortages, and switch days or verticals based on upcoming supply. It’s predictive infrastructure powered by live supply intelligence.

Why It Matters

TDS doesn’t just make life easier—it fundamentally reduces risk. In an industry plagued by non-compliance, ambiguity, and friction, TDS becomes the control layer. This isn’t just about buying data online. It’s about buying data safely, instantly, and with accountability baked in.

TheDataSupermarket is what happens when you combine an Amazon-style marketplace with serious compliance infrastructure. This is the future of data buying—and it’s already live.
