Hackathons have become a popular way for companies, universities, startups and technology communities to bring people together to solve problems, develop new ideas and demonstrate practical skills. Depending on the objective, a hackathon can involve building software, experimenting with artificial intelligence, designing a new product or finding innovative solutions to business challenges.

However, not every hackathon follows the same format. Some focus on technical development, while others emphasize business innovation, design, sustainability or talent discovery.

Understanding the different types of hackathons helps organizers select the right format, attract relevant participants and define meaningful outcomes.

In this guide, we explore the top 10 types of hackathons, their objectives, examples, benefits and the organizations that can benefit from hosting them.

How to Choose the Right Type of Hackathon

The right format depends on the outcome you want to achieve. Before planning an event, identify the primary objective, target participants, available resources and expected deliverables.

1. Define the objective

Decide whether the event is intended to develop prototypes, discover talent, improve products, engage employees or explore new business ideas. This decision will influence the format, judging criteria and participant profile.

2. Select the target participants

Identify the people best equipped to solve the challenge. A machine learning event may require data science experience, while a design hackathon may benefit from UX designers and product managers.

3. Choose a suitable format

Hackathons can take place in person, online or through a hybrid format. The appropriate option depends on the challenge, participants' locations, equipment requirements and collaboration needs.

4. Establish evaluation criteria

Explain how submissions will be judged. Depending on the event, criteria may include originality, technical execution, feasibility, usability, business value, accessibility or impact.

5. Plan what happens after the event

Determine how promising ideas, prototypes or participants will be supported after the hackathon. Follow-up could involve mentorship, product development, further evaluation or recruitment conversations where appropriate.

Why Do Companies Organize Hackathons?

Organizations use hackathons for different business objectives. The most suitable format depends on whether the company wants to engage talent, develop ideas or solve a specific technical problem.

Talent discovery: Hackathons give participants an opportunity to demonstrate practical skills through projects and presentations. Employers can use the experience as one part of a broader talent evaluation process.

Employer branding: Campus and public hackathons provide opportunities for companies to introduce their culture, engage participants and communicate the kinds of challenges their teams work on.

Innovation: Internal and external hackathons can help organizations explore ideas that may not emerge through routine project workflows.

Product development: Software, AI and hardware hackathons can produce prototypes that organizations may evaluate for further development.

Employee engagement: Internal hackathons can bring together employees from different departments and encourage collaboration beyond their usual responsibilities.

A successful event should have a clearly defined purpose. Organizing a hackathon without a plan for evaluating submissions, communicating outcomes or supporting promising ideas can limit its practical value.
