Google has acquired Sigmoid Labs Pvt Ltd, a Bengaluru-based start-up that owns travel app Where Is My Train. Announcing the acquisition on its website, Sigmoid Labs said: “We created the Where Is My Train' app with the mission to use technology to improve the lives of millions of Indian train travellers... we're excited to share that Sigmoid Labs, the team behind the app is joining Google...” Bengaluru based Sigmoid Labs was founded about two years ago by former TiVo Corporation executives Ahmed Nizam Mohaideen, Arun Kumar Nagarajan, Balasubramoniam Rajendran, Sashikumar Venkataraman and Meenakshi Sundaram. The company's app enables travellers to keep track of train schedules and provides information on the availability of seats and reservation status. It claims more than 10 million downloads on Google's Play Store. Google has made several start-up investments and acquisitions in India in the recent past. In July last year, Alphabet Inc acqui-hired Bangalore-based artificial intelligence (AI) venture Halli Labs. In December last year, Google had invested over $12 million in Bangalore-based daily tasks management app Dunzo, in a Series B funding round.
