Vipul Ved Prakash
In 2013, Topsy was acquired by Apple Inc. The acquisition was reported to be valued over $200M.
In early 2000s, Prakash became widely known for creating Vipul's Razor, a popular open-source anti-spam system. He was named to the list of Top 100 young innovators in the world by MIT Technology Review for this work on anti-spam.
Vipul Ved Prakash grew up in New Delhi, India. He played competitive Table Tennis, and attended St. Stephen's College, Delhi for undergraduate studies in Mathematics, Physics and Computer Science, but dropped out to pursue his interests in software design.
In the late-90s, Prakash co-founded, with Ashish Gulhati, an Internet privacy company (Sense/Net) for early Internet users in India and wrote for computer magazines and industry journals, including a regular column, Net Zeppelin, on networking protocols for the Indian edition of the PC World Magazine.
In May, 2000, Prakash and Rishab A. Ghosh, published the Orbiten Free Software Survey, which is considered to be the one of the first successful attempts at building an empirical model of contribution to Open Source projects.
Prakash considers himself a cypherpunk. He created a dolphin-shaped implementation of RSA algorithm in Perl that was printed on a T-shirt and sold by ThinkGeek as a protest against restrictive exports laws.
After Topsy’s acquisition by Apple, Prakash serves as a Director of Engineering at Apple, Inc and is rumored to be leading a growing search program inside the company. He appeared on WWDC 2015 stage to introduce iOS Search APIs.
