Be it a romantic dinner on an isolated mountaintop, or just a cab to the airport, or rescuing you from your broken down car in the middle of the highway. If you want to book a tatkal ticket or craving for some food at 3am. And they say Tathastu, literally.

Tathastu (literal meaning amen or so be it), a whatsapp-based 24/7 personal assistance service, launched by a group of students from IIT-Bombay about 25 days ago is fast catching the attention of citizens, with orders pouring in round the clock from busy, young professionals to senior citizens.

The orders need to be placed on WhatsApp after registering on the website (http://www.tathastunow.com) which is free. From the beaten to the offbeat, the plain to the eccentric – Tathastu aims to be everyone's free personal service or e-concierge service, which is relatively new to India though very common abroad.

The team includes Prashant Chandra Villa, who completed his dual degree course in mechanical engineering this year and this year's passouts graduates Nivedan S, Chirag Chadha and Anshul Awasthi, and a couple of delivery boys.

Explaining their business model, Anshul said, "We have our own delivery mechanism which is expanding day by day to cater to the various requests of customers such as "Get me Pizzas at 3 AM" or "Deliver this package from Point A to Point B". For certain requests, we outsources the job to other companies."

"Young professionals are our main customers who don't have time due to hectic schedules. At the same time, we are catering to elderly people with the two most popular requests being - Medicine Delivery (round the clock) and getting errands done," Anshul continued.

Some of the most interesting requests made by Mumbaikars so far have been-helicopter ride, dinner date on a cruise, organising a party in 2 hours, assemble a desktop, customised face-masks in 3 hours, a tatkal passport done within three days, and getting steaming coffee delivered at 4am.

Elaborating on their plans, Chirag said, "In a few months, we'll be moving to an app-based platform. The inertia to move onto an app is a lot higher than that of using a WhatsApp contact, since people are already used to the interface. And then we would go pan-India."
