Got an iPhone? Now you can use it with Pingdom!
BTW, another service like Pingdom is Site 24x7.
Site 24x7 is from AdventNet, the same company that is behind the Zoho suite of web apps.
I read somewhere recently that Union Square Ventures (USV) uses Zoho. USV is the VC company in which widely read blogger and venture capitalist Fred Wilson is a partner,
Fred's blog, A VC, is one blog I read regularly (among a handful of other ones). Apart from just talking about venture capital deals he's involved in, and the VC industry in general, he talks a lot about web technology, startups, entrepreneurship, possible new areas for startups to work in, web software tools he uses, etc. And most of the posts are interesting and useful to people involved in those areas, IMO.
Zoho was recently awarded Best LittleCo of 2008 by ReadWriteWeb.
