The productivity software company Zoho has never taken outside funding and plans to stay private. Zoho chief strategy officer Vijay Sundaram says the company can more easily take a long-term view. Zoho currently competes against software giants like Atlassian and ServiceNow. The 25-year-old productivity tool company Zoho believes that staying private has been one of the keys to its success — and doesn't have any ambitions for an IPO. Zoho, along with its IT service management division ManageEngine, offers a suite of productivity and business applications and competes against public software giants like $57 billion market cap Atlassian and $95 billion market cap ServiceNow. Unlike those competitors, which raised $522 million and $269.28 million from investors, respectively, before going public, Zoho has never taken outside investment.
