3. Hacker Earth

After registering on Hacker Earth, you submit your project on the Impact Hackathon page - junction.hackerearth.com The submission should be straightforward, however, in the description field, submit a link to your Product Hunt post! (A link in the form of something like www.producthunt.com/posts/MY_PROJECT or www.producthunt.com/upcoming/MY_PROJECT)

For more information about why we use Product Hunt, how to make a good post there etc., see the slides from our Webinar. If you want to watch our webinar, here’s the recording!


The hackathon includes the following three challenges. You can participate as a team or by yourself, and after the hackathon begins, you can submit your project throughout July 1-21. The project should be a live running website/webapp/ or service, so that others can interact with it. Details on the submission will be provided as the hackathon begins. For questions, you'll reach us best on Slack!

In order to compete for the main prize, the project must use at least 2 API's from the Rakuten RapidAPI database. Get your free credits here!

Check out these instructions on how to get started with a Rakuten RapidAPI! For some example API's, check out: SendGrid, Kairos Facial Recognition and Microsoft Computer Vision.



According to a 2019 Beijing University study transportation is one of the biggest causes of emissions in the world, 25% of all CO2 emissions, and urban traffic is one of the major contributors. In an increasingly mobile world, the total emissions from travel are ever increasing. One major player in all of this is our workplace. A large portion of the world’s population commutes to work five or six days a week, and because business hours are a universal thing, traffic jams make the problem even worse. In addition, due to globalization, employees travel a lot more during their business trips. Regular company flights to the other side of the planet are common.


Overall, we need sustainable solutions for workplace transportation, now and especially in the future. We've identified some key problems to be:

  • Commuting is generally quite far from optimal. Fixed working hours make traffic jams the norm, increasing pollution and wasting valuable time. Most people drive alone in a 5-seat car, instead of carpooling with co-workers.
  • Companies want to be eco-friendly, but not many turnkey solutions exist for encouraging employees to commute more sustainably
  • Business trips to far away countries are considered necessary - could there be a service which helps companies reduce their total amount of air miles by e.g. scheduling and grouping together business trips in an optimal way? Or one that encourages companies to host remote meetings instead?


We are looking for a game/product/service that addresses one of the problems above, or perhaps another problem related to sustainable transportation which you have identified yourself. Your submission should be an up & running online app which people can test themselves. It doesn't have to be a ready product, but should already have some working features. Try to think of solutions that could be generally adopted among companies and have an immediate effect on their sustainability.

The world changes in an increasing pace, industries come and go, which means most adults will face the challenge of hopping between multiple careers. People already switch their jobs on average every four years and end up having around 12 jobs during their lifetime. However, our current education system is based on becoming an expert on a single topic. Clearly, in these turbulent times, that has to change. Considering complex problems such as climate change, political instability and more rapidly spreading diseases (due to high connectivity), the solutions will not be found from just a single source. Thus the future of learning has to be life-long and extremely diverse.


In the tech industry it is common knowledge that the current state-of-the-art technology will be outdated in five to ten years. This has made tech the most agile industry. So how can we apply this mindset to other industries as well and encourage people in those industries to develop their knowledge?

Key problems

  • How can we ensure everyone is able to educate themselves throughout their lives?
  • How can we make online learning more personalized and optimal?
  • How can we measure the quality and objectivity of learning materials?


We’re looking for a web app that addresses one or more of these problems. The app could, for example, optimize e-learning, help people continue learning throughout their lives, or measure the quality and objectivity of learning materials.

At BlackRock, our goal is to use technology to create better financial futures for our clients. As masses of people are lifted from below the poverty line in the coming decades, we need more tools that help people save money where they can to help towards their personal savings goals and become more aware of their financial status.


There are hundreds of apps out there which help to track your spending habits, but they often seem to try and over-simplify a rather complex subject. Typically, you connect your bank account / credit card to a spending app, and it does at least the following:

  • Groups your spending by category
  • Shows you your monthly total spend, daily averages, and so forth

However, for most people this kind of information will remain a mere curiosity and do little to help them control their spending. The purpose of this challenge is to improve upon the existing spending apps. Here are a few improvement ideas we've identified:

One major downfall of current spending apps is that they don't take into account the "cost per lifetime" of items you purchase. If you purchase a new laptop or phone, your entire monthly budget will be "ruined" due to the huge upfront cost. If you could accurately determine the expected lifetime of the product, you could get a much better picture of the actual cost, which would likely be just a dollar or two a day. On the other hand, buying an expensive pair of jeans might seem like a reckless decision, but if they last 5 times longer than a cheap pair and have a lifetime warranty, it's probably a smart purchase as opposed to the cheap ones. Depreciation of purchases spanning multiple financial years is common practice in the business world - could the same idea work with personal finances? Perhaps you can think of e.g. crowdsourced or AI-based tools to better evaluate the true "cost per lifetime" of purchases?

Another common trait we've identified is that spending apps largely rely on your purchase history and don't do much to actually enforce healthier spending habits in the future. Often they have no idea of your spending trends within a month - perhaps you tend to pay your bills near the beginning of the month, which might make the app wrongly project you are going way over your monthly budget. They rarely give you advice on what kind of purchases to avoid to stay within budget, what a good monthly budget would even be based on your stable income, how much you should be saving each month based on your financial environment, and so forth. What are some ways you could improve spending apps to help people better understand their budget, stay within it and put just the right amount of money aside at the end of each month?


We are looking for a game/product/service that addresses one of the problems above, or perhaps another problem related to personal finances which you have identified yourself. Your submission should be an up & running online app which people can test themselves. It doesn't have to be a finished product, but should already have some working features. Try to think of solutions that could be easily adopted and generalisable to all over the world, not necessarily specific to your area.
