Windfall Intelligence and Windfall Data: not the same company
Two companies share a word. One reads the UK public record for private bankers; the other sells people intelligence to go-to-market teams.
A name with luck in it is bound to be shared. This page exists so that nobody mistakes one Windfall for another, in either direction.
In short
Windfall Intelligence Ltd, registered in England and Wales under company number 17301158 and trading at joinwindfall.com, writes a daily brief for UK private bankers and wealth managers from the UK public record. As at 2 November 2026 it has no connection with Windfall Data, Inc., which describes itself on windfall.com as a people intelligence and AI company for go-to-market teams.

What does Windfall Intelligence do?
Windfall Intelligence Ltd writes one thing: a private daily brief for UK private bankers and wealth managers. Each working morning it reads the UK public record (The Gazette's notices, the filings and accounts at Companies House, the register of people with significant control) and names, for each member, a few people in that member's own patch whose circumstances have just changed, with the event, the evidence and the professional route in.
It is UK only by design. It does not sell a database, an API or wealth screening, and it never states a net worth for a private person. Its research pages, of which this is one, publish aggregate counts from the same record and never name a private individual.
What does Windfall Data do?
Windfall Data, Inc. operates the website windfall.com. Its home page, read on 2 November 2026, describes it as "a people intelligence and AI company that gives go-to-market teams actionable data to find, engage, and convert their next best customers", and lists products including wealth screening for nonprofits, an API for wealth and career data, and propensity modelling.
The house makes no further claim about Windfall Data's business than its own pages make. Anyone evaluating it should read windfall.com directly.
