Web Office suite provider ThinkFree has announced it has hit the 1 Million mark in number of hosted documents, up from 654,000 in late February when we last reported ThinkFree’s usage. Their community uploads between 60,000 to 80,000 documents per month and currently ThinkFree has 335,000 users, up from the 250,000 in February.

ThinkFree also stated in their blog post that they are the number 2 Web Office suite provider, behind Google Apps. They wrote:
“GD&S is a great lightweight tool, but having the best MS Compatibility and the highest level of feature functionality of any online offie suite has propelled us into the second spot.”
ThinkFree’s main startup competitor Zoho also recently announced user numbers, stating that they have over 300K users. The current figure is around 310k, according to a Zoho representative I checked with tonight.
Judging by the figures both companies provided, it seems that Zoho’s growth rate is stronger. According to their blog post, Zoho took “12 months to get to the first 100K users, 6 months for the next 100K users and 4 months for the last 100K users.” However it’s great to see that both Web Office startups are experiencing high usage and growing well. While Google is the dominant player in this market, both ThinkFree and Zoho are an acquisition away from being major players in the office software market (e.g. Microsoft or Oracle might buy them).
Disclosure: Zoho is a R/WW sponsor
