Engie has a pretty great product here! It's intuitive, it's useful, and it's definitely getting a lot of attention. There's still plenty of room for improvement, though, particularly in terms of the UI. For example, there's no obvious way to import customers into Engie; when you go to add a new user, you're asked to enter email addresses manually. There's also no automatic way to find new customers, so if you want to get more people signing up, you'll have to do it yourself. And finally, there's no way to segment data. If you're only interested in cars with certain attributes, you can't just filter your results by those attributes (and even if you could, the filtering would require you to click on each result individually). Overall, it's pretty nice, though, and there's a lot of potential here!
