She's made it big by sorting out the waste in e-mails. Pavni Diwanji’s latest software is a boon for those grappling with junk mail. A few years ago, she sold her software Kendara, an advanced search engine, for $1.2 million.The anti-spam software www.mailfrontier.com, designed by this 31-year-old entrepreneur, is in demand as junk mails flood e-mail accounts all over the world. The software filters e-mail accounts, lists mails in order of priority and deletes junk mail. ‘‘All over the world, IT professionals, MNCs and even individuals have to tackle the nuisance of junk e-mail on a daily basis,’’ says Pavni Diwanji, founder and COO of Mail Frontier. Diwanji, who hails from Ahmedabad, did her schooling from Gujarat Law Society and obtained a Bachelors degree from LD Engineering College in 1990. She then left for the US to complete her Masters degree at Stanford, after which Pavni joined Sun Microsystems in California.With CNN, SAP, AG Edward and over 200 clients, Pavni said that besides filtering e-mails, her software saves time. ‘‘Now, my clients don’t have to go through useless e-mails,’’ adds Pavni, who is here to visit her family.She says: ‘‘Every Indian has the basic instinct to work hard. It’s just the raw talent that has to be guided in the right direction.’’‘‘When I started working, the IT revolution was at its peak. And since then, there has been no looking back,’’ recalls Pavni, who has settled in California with her British husband and daughter.‘‘Indians are respected and considered very hard working individuals. They have carved a niche for themselves in the US,’’ says Pavni, who admits to learning her enterprising skills from her father, N. Diwanji, and mother, Toral.‘‘I worked with Sun Microsystems for seven years and then started my own company with a friend in 1998. My company — Kendara, an Internet assistant that provided relevant information about several sites, was purchased by excite@home, a popular search engine and now I just handle the spam company,’’ says Pavni. She now intends to start operations in India and says business here is thriving and is recognised in the international market. ‘‘I want to provide my software to Indian companies so that they too can get rid of spams,’’ she said.
