Any single contact-data source is meaningfully wrong: people change jobs, companies rename, inboxes close. Industry studies put B2B data decay around 30% a year — which means a list bought in January is a coin flip by summer.
Hyves treats no source as truth. Each fact is checked across a waterfall of licensed providers and public evidence until confidence clears the bar; email addresses are additionally verified live before they can enter a sequence. What fails verification never reaches your team — and never burns your domain.
Verification also runs backwards: dossiers carry a freshness clock, and facts past their reliable lifetime get re-checked or retired. The result is a number most teams have never seen on their own stack — a bounce rate low enough that deliverability stops being a project.
