Entity Resolution designed by Lumilinks

Are You Counting Customers — or Counting Duplicates?

In today’s fast-moving, data-driven world, bad data isn’t just an IT problem — it’s a performance blocker.

Lumilinks’ Entity Resolution application helps you cut through the noise. Built as a Snowflake Native App, it unifies and cleans your customer data, transforming disconnected records into a single, trusted view of each customer — directly inside your secure Snowflake environment.

Inconsistent, fragmented, or duplicate records quietly erode:

Marketing efficiency

Customer experience

Reporting accuracy

Revenue opportunities

Are You Counting Customers — or Counting Duplicates?

Why This Matters

Without accurate customer records, businesses struggle to:

Personalise marketing campaigns

Align service and sales efforts

Report confidently to regulators

Scale AI and automation initiatives

With clean, unified data, you unlock:

Smarter segmentation

Stronger customer relationships

Reliable analytics and machine learning

Faster, more confident decision-making

What Is Entity Resolution?

Entity Resolution (ER) is the process of matching and consolidating records that refer to the same real-world entity (like a customer or supplier) — even when details vary across systems.

For example,

John Smith | john.smith@company.com | +44 7000 123456

John S. | jsmith@company.com | 07000 123456

→ One person, Two records — until resolved.

Why Now — and Why Snowflake?

The demand for personalisation, automation, and regulatory confidence is growing. But legacy tools require moving sensitive data, managing complex infrastructure, or waiting through long implementations.

Lumilinks + Snowflake unlock a faster, simpler, and more secure path:

No data movement

Processing happens inside your Snowflake account, respecting existing security.

Zero-lift deployment

Install like an app from the Snowflake Marketplace.

Scalable by design

Built on Snowflake’s elastic compute and Snowpark Container Services, ready for enterprise workloads.

How It Works

Under the hood, our application deploys a multi-stage Entity Resolution pipeline optimised for speed, accuracy, and scale:

1. Data Preparation & Feature Engineering

We access raw customer data (via Snowflake’s secure data sharing), clean it, and extract meaningful features — using Snowpark or containerised code (SPCS) to handle complex tasks like embedding generation or advanced transformations.

2. Candidate Selection (Blocking & Filtering)

To avoid heavy pairwise comparisons, we use techniques like Approximate Nearest Neighbours (ANN) or graph-based blocking — reducing the search space and ensuring fast similarity matching, even at massive scale.

3. Matching (Classification & Comparison)

Our pipeline calculates similarity scores (using string distances like Levenshtein or Jaro-Winkler), runs classification models (even GPU-accelerated ones), and applies intelligent rules to determine which records represent the same entity.

4. Merging & Canonicalisation

Matched records are merged into a single, canonical customer view, applying logic to resolve conflicting attributes (e.g., latest address, preferred contact details). Output is delivered as clean, structured data inside Snowflake.

Why Technical Teams Love It

In-Situ Processing — Code runs inside your Snowflake account; no egress risk.

Scalable Compute — Leverages Snowflake’s elastic resources, including GPU pools.

Custom Code Ready — Run Python, Java, Scala, or containerised libraries.

Simple Management — Deployed, updated, and managed via Snowflake Marketplace.

Pay for Value Delivered — Monetised per “clean record” produced, aligning cost with outcome.
