The project 'Fuell' (getfuell.com) is a verified Y Combinator (W20) fintech company based in Spain that was acquired by the unicorn 'Factorial' in October 2023. However, the submission itself is of critically low quality, containing conflicting data (Project Name 'SwiftStorm', Business Type 'Electric mobility solutions') and fabricated traction claims ('most people have used my product'). While the underlying software is highly useful and commercially successful (proven by acquisition), the Proof of Usefulness submission fails to accurately represent the project, resulting in a low score driven by penalties for inaccuracy and lack of verifiable evidence provided by the submitter.

Description
We're building an all-in-one corporate card and expense management software. When you pay with a Fuell card, a notification will pop up on your phone to take a picture of the receipt. We're approved by the Spanish Tax Agency, so you don't have to keep your paper receipts anymore.\n\nWe manage expenses with budgets and you can request funds to your admin for instant top-ups when you're out of balance. Admins can track, manage, and limit cards, budgets, and overview the spending of the company in real-time. \n\nIn the back office, we send you monthly expense reports, help you get VAT returns, create virtual cards, and we'll be integrated with your accounting software automatically very soon.
