And here is the fourth and final installment in our series (1-10, 11-20, 21-30) on Y Combinator startups that just might help you save some time, save some money, and even save you from some unneeded headache. These Internet startups have all received seed funding and much needed guidance from Y Combinator, allowing them to get off the ground and into the public eye.

Today’s list is a little more special, because they’re all startups that have only “graduated” from the Y Combinator program within the last two years. Many of them are still trying to get the exposure that they need, but they’re all up and running, ready to help you live the smarter life. Are you ready to get a little more organized and have a few extra nickels in your pocket?

31. Gantto

Gantt charts, originally developed by one Henry Gantt, are an organizational tool that help you illustrate a project schedule. This is particularly effective when the project elements have timelines that overlap, giving you a better grasp of what needs to be done, what is currently being done, and when it all needs to be done by. With Gantto, creating these charts on your computer are a piece of cake and you can even have multiple people collaborate on the charts in real time.

32. WorkFlowy

On the surface, WorkFlowy might look like just another “to do” app, but it’s actually much more powerful than that. The idea is that you can jot down notes (and yes, these can be to do items) in a manner that is similar to how your brain operates. Create nested bullet points for what you need to do and use it to organize your ideas into something a little more digestible.

33. AnyLeaf

Even though I pretty much live on the Internet, I still get a little giddy when the flyers get dropped off at my house. Yes, it’s mostly junk, but I do like seeing what deals are happening around town. With AnyLeaf, the process is a lot easier, because you can sift out all the products that don’t interest you. You’re then left with “unbelievable deals on local groceries” based on your individual preferences and these are sent to you as a daily digest for free.

34. AeroFS

While services like SugarSync and Dropbox are a great way to synchronize your files across computers, they inherently come with limited storage. AeroFS takes a different approach, synchronizing files without having necessarily to turn to the cloud. Your files aren’t saved in the cloud unless you specifically enable Cloud Backup; otherwise, your files can then stay in their respective local locations. In essence, you have your own peer-to-peer network for your personal files, all without having to resort to servers.

35. TellFi

There’s something to be said about the appearance of professionalism. If you want to have a business phone system, complete with extensions and voicemail, but you don’t want to invest in the physical infrastructure, TellFi could be an intriguing solution. You get all the features that a business phone system would normally have, but it’s all handled online and it costs as little as ten bucks a month.

36. HelloFax

On the subject of communications, many of us feel that fax machines should have gone the way of the dinosaur ages ago, but somehow they linger as a necessity for many businesses. Why not do away with the hardware and use HelloFax instead? It’s basically an online fax machine that works with both sending and receiving, getting signatures, filling out forms, and all the rest. The free plan includes five fax pages and five signature requests per month.

37. Tutorspree

The Pythagorean theorem have you confused again? Can’t figure out all this quadratic equation nonsense? Little Timmy asking for help with homework, but you haven’t a clue where to begin? Instead of sifting through Craigslist and browsing local bulletin boards, you might want to use Tutorspree to find “great private tutors in your area.” This is a simple, straightforward, and hassle-free way of finding the right tutors quickly and effectively.

38. ZeroCater

Need to feed a bunch of people in the office and many of these people have certain dietary preferences? Take the hassle out of catering with ZeroCater. They “arrange delivered meals for your company from the best local restaurants.” They’ll cycle through a rotation of more than 90 local restaurants that you can then rate, giving ZeroCater the opportunity to adjust the kind of food they send. The fee is a 7% charge on the normal cost of the meal.

39. ScreenLeap

Want an easier way to collaborate or offer tutorials? ScreenLeap allows you to “share your screen instantly to any device with a browser.” The cool thing is that you don’t have to download or install anything, so it works from right within your browser. It doesn’t cost a thing and the viewing can be done not only on PCs, but also tablets and smartphones. This is great for seminars and team projects.

40. Science Exchange

Granted, this is going to be a pretty specialized service, but it is one that could “dramatically change the weay in which scientists do research.” Science Exchange is essentially a marketplace where researchers in different facilities and institutions can offer up their machines and services to other scientists and researchers. This makes it easier to outsource experiments, getting access to specialized equipment, reduce the cost of science, and expedite the pace of innovation and discovery.

And there you have it: forty Internet startups that couldn’t be more different in the services they provide, but they all got some great seed money and guidance by way of Y Combinator.
