Copper

Copper (formerly ProsperWorks) is a wildly unique, highly specialized titan that achieved massive market success through a terrifyingly strict, singular architectural obsession: "Google Workspace." Copper completely refused to build a standalone web app. Instead, it mathematically embedded its entire Contact Management database directly inside Gmail and Google Calendar, making it the absolute weapon of choice for companies that live entirely in the Google ecosystem. Its absolute biggest differentiator is "Zero Data Entry (Gmail Native)." A sales rep literally never opens a new tab. When they open an email from a new prospect in Gmail, Copper sits in a sidebar on the right. It instantly scrapes the email signature, mathematically generates the Contact Record, links it to their company, and pulls in their social profiles. The rep clicks "Add," completely eliminating the copy/paste nightmare. Because it lives inside Google Workspace, its "Activity Scraping" is flawless. It automatically, mathematically tracks every single email sent, every calendar invite accepted, and every Google Drive file shared with that contact. If a manager wants to know the history of an account, they don't have to ask the rep. Copper has already built a flawless, automated chronological timeline of every Google interaction the entire company has had with that person.
