An Indian company offering a service that blocks spam from mobile phones has received seed funding to increase its user base.

Phone Warrior, a New Delhi-based company offering an Android and BlackBerry app that identifies and blocks spam phone calls and messages, received $550,000 in seed funding from Lightspeed Venture Partners, according to published reports. The funding will be used to increase the app's user base from one million users to ten, as the company finalizes plans to launch an iPhone version of its product early next year.
