Some large U.S. multinationals are adapting their worldwide privacy policies to comply with the European rules, rather than have different policies in different countries.
Others want to be ready in case similar rules are enacted on this side of the pond, which Microsoft and Facebook, among others, are calling for.
Killi recognizes this as a business opportunity, facilitating opt-ins for data sharing.
The company also is responding to California's toughest-in-the-nation privacy law, the California Consumer Privacy Act of 2018, which requires all companies doing business in the Golden State to give customers more control over how their data are used.
State voters are so enthusiastic about that, they voted last month to give the law even more teeth.
Sweeney acknowledged that providing clients with data-sharing opt-ins is a major part of Killi's business.
"This concept of consent is a big service we provide companies," he said.
"We're not eliminating any data from the marketplace," Sweeney observed. "Don't be under an illusion that your data still isn't being sold. But we're getting the consumer involved."
He declined to name Killi's clients, saying only that they include "large Fortune 500 companies."
Killi has three tiers of data-sharing consent, each more revealing than the last. At a minimum, you'll be asked to provide your date of birth, email address, gender, location, phone number, postal code and country.
