I believe you have Zoho confused with another company. Zoho has never taken any outside investments and has always been bootstrapped. There are countless articles about Zoho being bootstrapped online as well as on Zoho’s web pages. Disclosure: I work for Zoho.
Of course I didn't know that, but if true, that's wonderful. I am saddened by the ongoing destruction of value when a decent product or company is acquired, and then shuttered because it's not quite the juggernaut the acquirer expected it to be, or because there's some unforseen misalignment, even though this company was a viable business. Selling it back is a great solution, instead of doing a write-off where the company is destroyed.
I dont think Zoho was ever acquired. They were and are still are a private company with no external investments. Interestingly the confusion seems to be with Zimbra and here is a blog post on Zimbra acquisition by Zoho themselves.
