Sunil Mahajan had a torrid time a couple of summers back. His air-conditioner went bust in the middle of a scorching Delhi summer but what made it worse was that he could not locate the warranty card and had to shell out Rs 10, 000 for a new compressor even though the warranty period had not ended. Mahajan, instead of getting mad, got organised. Last year, with a partner, he started an online service called Kleeto. in that allows people to store everything from receipts to warranty cards, mutual fund and property documents or car insurance papers physically in one place as well as in a digitised form. Swelling dossiers for a lifetime of investments and purchases, busy schedules, and just a general inertia against document management is seeding a new way of storing critical documents online. No more backbreaking searches in old trunks and dusty drawers for that elusive class X board exam certificate which is a must for your all-important visa application.
