same·sake noun: two or more records, in different systems, that turn out to be the same person.
One customer,
recognised everywhere.
Your CRM, billing and support systems each know your customers a little differently. No more searching every system for one customer: Samesake links the records that belong together. If a match needs a closer look, it asks your team first and shows them why.

How Samesake decides
Strong evidence
It links them for you
It weighs everything it can compare, not just exact matches: a nickname, a typo, a swapped date of birth, the same house written another way. Strong evidence links on its own.
A closer look
It asks first
Doubtful pairs wait for one of your team to confirm, with the two records side by side.
Every time
Decisions stick
A rejected pair is never linked on its own; it only comes back if the evidence gets much stronger. A confirmed link isn't quietly undone.
How it works
Connect your systems
Customer records come in from your CRM, billing, support and other systems through the API or CSV files, often from a simple flow that runs whenever a record changes. Your systems keep owning their data; Samesake only reads it.
Samesake matches; your team confirms
Each field adds or takes away a visible weight. Strong matches link automatically. Doubtful pairs go to a review queue, where one of your team decides.
One ID, wherever you need it
An identity map links each source record to a shared customer ID. Power BI and Excel can read it for reports; Azure Data Factory or similar tools can use it in your other systems.
What teams use it for
Here are a few examples of the everyday jobs that get easier when your customer records are linked.
Erasure requests
Find linked records across connected sources and track erasure in each one.
Find anyone, everywhere
Find a customer’s linked records in one place.
Duplicates in your CRM
Review likely duplicates alongside records from other connected systems.
Opt-outs honoured everywhere
Identify the records an opt-out needs to apply to across connected systems.
From enquiry to quote to sale
Follow each customer from first enquiry to sale in Power BI.
Contacted too often, or not enough
See how often each customer hears from you, across every system.
Who it's for
Business teams
One view of each customer, without the detective work.

Finds your duplicates without touching them
Your systems stay exactly as they are. Samesake reads their records, recognises which ones are the same customer and links them, without changing, merging or deleting anything. Your systems stay the owners of their data.
