Hackathons, besides being a place of sleep deprivation and hard work, can be a powerful fuel for innovation. Indeed, these types of events are ideal to validate a product idea and create a startup out of it. In this post, we’ll explore how a startup hackathon can be a fantastic starting point for a company, along with some success stories of startups that emerged from hackathons.

What is the purpose of a startup hackathon?

There are several types of hackathons. However, they commonly happen over a weekend and involve a team who has to rapidly come up with a solution or prototype. The best projects will be later presented in front of a panel of judges.

These events test participants’ creativity and their ability to work under pressure. In a hackathon, you have to fiercely innovate and create a viable solution to a specific problem. For this defining characteristic, hackathons were many times the fuel where a successful startup emerged.

Because at their core, startups are exactly that: an innovative solution to a specific problem. Indeed, launching a product involves connecting with potential customers to make sure its features are really an innovative solution to a problem they are facing. Hackathons help you validate the product idea and work on it fast.

However, successful startups need more than a great idea (a big part of them is having a strong team). Hackathons alone aren’t enough to develop a successful startup, but they can be awesome to expose potential benefactors to your idea, get funding, and further support.

Another big aspect of becoming a successful founder is community. Networking is essential, not only to find co-founders if you want, but also to develop strategic partnerships, meet investors, and make new entrepreneur friends with whom to exchange knowledge and advice.

In this sense, online and offline startups and entrepreneurs/founders‘ communities are fantastic to get accountability and learn how to be a successful founder. Here is a list of top picks from Unita’s directory of communities:

Hackathon success stories: 5 Startups that emerged from hackathons


Wade Foster and Bryan Helmig are Zapier’s founders, an automation tool to improve workflows by using integrations with other apps. Before creating Zapier, they were musicians and played in a jazz & blues band. They shared a passion for creating web apps, and during their day gigs, they found themselves messaging startup ideas back and forth. That’s how the idea of Zapier was born:

So, they built a demo version of their app in a few weeks and presented it at Startup Weekend in Columbia, Missouri, which happened from September 30th to October 2nd, 2011.

The app, which Bryan originally named “API Mixer,” won the competition. Later, they changed the app’s name and applied to the accelerator program Y Combinator. Zapier officially launched in June of 2012, offering integrations with 34 apps (nowadays it has integrations with 4,000+ apps!).

Just two years after launching (and with only one round of Series A funding, totaling $1.3 million) Zapier became profitable. Between 2016 and 2018, Zapier’s ARR grew from $10 million to $50+ million. Nowadays, they’ve grown to $140 million in ARR and a valuation of $5 billion, all while on profit.

Talkdesk is a cloud-based call center solution that revolutionized the call center industry. The idea was born out of a Twilio hackathon in 2011, and its founder is Tiago Paiva. In an interview, he said:

One day, I saw that Twilio was giving a MacBook Air as a prize to their hackathon. All you had to do was build something using their newly released Twilio Client. I was 24 years old and I had an old PC and no money to spare – I wanted that MacBook. So I spent the next 10 days building what is now Talkdesk.

A few months later, Talkdesk was presented at TwilioCon and won first prize: a $10,000 investment in this startup. In 2021, the company announced the closing of its Series D funding, more than tripling its valuation in just a little over one year from $3 billion to $10 billion. Indeed, the company is now among the most highly valued private companies in the SaaS industry.


Carousell is a Singapore-headquartered online consumer-to-consumer marketplace that allows users to post classifieds to sell different items. Siu Rui Quek, Marcus Tan, and Lucas Ngoo, three college friends, started Carousell back in 2012. The product idea was validated at a hackathon in Singapore, where they developed the first prototype.

The team ended up winning the Startup Weekend Singapore 2012 hackathon. In 2019, they already won top investors’ support and earned a valuation of $550 million.

Docracy is an open-source repository for legal and business documents (similar to what GitHub offers for code). The founders of Docracy are Matt Hall And John Watkinson, who saw a real problem in how difficult it was to find trustworthy business legal documents online. As a solution to this problem, Docracy was born.

Founders participate in the TechCrunch Disrupt Hackathon in 2011, and their project was one of the winners among over 100 participants. The startup raised a total of $850,000 in funding over 2 seed rounds, one in 2011 and the next in 2013.

PowerWells is a socially-focused Australian startup. They have the mission of changing the quality of life for people living in remote Indonesian villages who have to travel for half a day to have access to electricity. Nick Kamols and Brad Claire, PowerWells’ founders, had the idea to install solar-powered battery packs created from e-waste.

Kamols and Claire took this idea to Startup Weekend and went from a hackathon concept to a full product launch in just four weeks. They embarked on a crowdfunding campaign to install the first 100 PowerWells, and later sought corporate and venture capital investment to keep growing the startup.
