Vantus

Vantus is a stub surfaced from the Mayfield portfolio page whose permalink slug is "vantus" but whose actual company is Vantive Corporation, a historic Mayfield "Milestone" enterprise investment described by Mayfield as call center software leaders. Vantive provided customer relationship management (CRM) software and existed as an independent corporation until its merger with PeopleSoft in 1999; PeopleSoft was later acquired by Oracle and the Vantive brand no longer exists. There is no current company website or API surface to enrich. Unrelated live domains (vantus.com, Vantus Medical Systems; vantus.io, a Spanish AI automation consultancy) are different companies and are intentionally not linked here.

Vantus is profiled on the APIs.io network. Tagged areas include Company, CRM, Call Centers, Enterprise Software, and Customer Service.
