Expensify , the startup that took second place at TC50's demo pit last year, has launched the public beta version of its business expense tracking and reimbursement system. Expensify has created a bigger and better version of its system, which we reviewed last fall. Expensify still offers the “electronic payment card,” which is essentially an Expensify-branded MasterCard that is linked to your original credit card (which doesn't have to be a MasterCard). When you use this card, business expenses are immediately charged to the linked credit card's account. Not only does this allow you to still rack up any frequent flier miles associated with your credit card but it takes only a week to get the card and you don't have to undergo a credit check. You can get numerous cards (and are able to manually write what each card id for in a blank white spot on the top of the card), which is ideal for consultants who are billing reimbursements to different clients.
