Frequently Asked Questions

What are the main types of hackathons?

There are four core formats: internal (employee-only), external (open to outside developers), virtual (fully online), and in-person (on-site). Everything else, like social good, AI, or ecosystem development, is a theme or focus layered on top of one of those formats.

How do I choose the right hackathon format and focus?

Consider your primary goal: use internal hackathons for employee engagement, ecosystem hackathons for developer adoption, virtual formats for global reach, and in-person events for intensive collaboration and networking.

What’s the difference between an internal and an external hackathon?

An internal hackathon runs on employee-only participation and targets company challenges, talent, and engagement. An external hackathon opens registration to outside developers to drive adoption, brand awareness, and fresh ideas.

What makes a hackathon successful?

Successful hackathons align challenge statements with clear business or strategic goals, provide strong mentorship and technical support, and include post-event follow-through such as incubation or acceleration programs.

Should I run a hackathon in-house or hire an agency?

Run it in-house for small, low-stakes programs when you have the time and event experience. Consider a hackathon agency when the event spans multiple cities, carries brand visibility, or needs developer recruitment and post-event follow-through you can’t staff internally. Our 2026 guide to choosing the right hackathon agency covers how to run a selection process you can trust.
