Navin,

No issue, I guess it was a communication gap from my side.

Thanks a lot of covering the article,

@Jaspreet, I was not aware of the fact that your flagship product was priced higher than competing offering from Veritas. At a cursory glance, I thought you were priced much lower than them. But in any case, software product lines and prices these days are so complicated that I can’t really figure out what the cost is in any case. For products from some of the larger companies, I seriously need a consultant just to figure which version of the product to buy

But in any case, I guess the point you are trying to make is that you are selling on features and TCO rather than just the price of the software.

Dhananjay,

The introduction to company says – “Druvaa is a Pune-based startup that sells fast, efficient, and __cheap__ backup software for … ”

The word “cheap” automatically gets associated with any Indian startup. And I don’t quite like it. So i felt like correcting it.

Sorry, if that sounded like a pitch. But that wasn’t the intention, its not the market we intend to sell in.

In response to a comment. Correction to what ? Seemed like an introduction of a new thought. Did I just smell a pitch on a technical article ?

Dhananjay,

Fyi, at Druvaa we use source based sub-file level deduplication with variable-sized data segment approach.

I know only 2 companies besides Druvaa which used source based dedup.

Just a small correction. The flagship product is priced 3 times the cost of competing veritas product. Still it sells like hot cakes .. because we can proudly succeed where veritas fails.
