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.

I think you're confusing Zoho for Zimbra. Zoho was never bought and they intend to stay private. In fact, the co-founder is very vocal about it.

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.

When did this happen? I just couldn't find any links. Is it Zoho or Zimbra?

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.

I don't think that's Zoho. Yahoo acquired Zimbra.

Yahoo tried to acquire Zoho. But, Zoho denied the offer from yahoo
