Tips to build a winning product

Looking for a million-dollar idea? Here are a few tips to get started:

1) Create a product that you would use

Start by solving a problem for yourself in a simpler way than anyone else. Is there a problem your friends complain about for which you have a simple solution? Can you offer an innovative solution in place of an outdated product? When you build a hack for a problem that you face, you get a clear end-user perspective. You are more likely to build a product that you would use personally. It’s very likely that such a product will be used by others as well who face the same problem as you.

2) Know your market

Getting the product-market fit right is the secret to the success of a new product. When you give people what they want, they are more likely to use and endorse your product. By investing time in understanding the needs of your target market, you can build a loyal group of users for your product.

3) Validate your idea

A hackathon is a great a place to test and validate your ideas. Take inputs from teammates, companies, and mentors to see if your product is likely to solve their problem. Test your prototype with friends, family, and colleagues. Collect honest feedback to know if you are on the right track.

4) Don’t be afraid to take the plunge

Often, great ideas happen by chance. It is OK if you are not 100% confident about the result. Start small and build a simple prototype. Don’t be afraid to give your ideas a chance. Who knows, you may be working on the next billion-dollar project!

5 simple tips to survive your first hackathon

There is a first time for everything. If you are attending a hackathon for the first time, it helps to be prepared. With the right preparation, you can make your hackathon experience more fun and productive. At HackerEarth, we have conducted over 800+ hackathons worldwide. In this blog, we are sharing our top tips to help you get the most of out of your first hackathon:

1) Know what you want to accomplish

Victory lies in the eyes of the beholder. When it comes to hackathons, bagging the prize money is not the only win. Hackathons are a fun way to build cool products, meet new people, learn something new, and even find a good job. Define your victory for your first hackathon. Know what you want to accomplish. Are you building something for your portfolio? Do you want to learn more about an app or API? Are you trying to build your professional network to find a job? At the end of the day, if the experience motivates you to achieve more, it is a victory.

2) Do your homework

Start by brushing up your programming skills. Go through APIs, open source libraries, and hackathon themes, if any. Check out if there are any existing templates that you can use. Practice your introductory pitch at home. Jot down ideas that you can use. Bookmark websites that offer free templates and prototyping tools.

3) Don’t forget to bring the necessities

Make sure you take everything you need including your laptop, USB chargers, pen drive, etc. Although internet access is free at the hackathon venue, it is a good idea to have your back up ready, just in case.

4)Reach the venue on time and network

Being on time not only makes you look professional, it also gives you the chance to talk to everyone at the venue. Once the hackathon starts, almost everyone will be too busy with their projects. The best time to network is at the beginning of the hackathon. Use the opportunity to introduce yourself, present your pitch, and connect with people. If you have not formed your team, try to get people onboard. Talk to the organizers and sponsors to get some tips. Many hackathons also have company-sponsored booths, fun activities, and workshops. You can meet headhunters and maybe even take home some cool hackathon giveaways like T-shirts, laptop stickers, etc.

5) Be willing to teach and learn

Depending on your team and the prototype that you plan to build, you need to be ready to learn and teach. Don’t start building immediately. Brainstorm with your team to finalize a strategy to build a Minimum Viable Product (MVP). Be honest about what you can offer to the project. Assign ownership of tasks to team members according to their skills. As you build new products, you may have to learn new technologies and implement them on the fly. You may also have to explain technical concepts to your teammates who aren’t familiar with it.

Lastly, try to get enough rest and remember to have fun! You can perform your best when you are rested and happy. If you are focused and relaxed, you can code better and reduce the likelihood of bugs.

With the right attitude, teamwork, design, and presentation, you can make the most of your first hackathon.
