Announcing $10,000 Leonhard Euler Idea Contest Winners

Thanking all participants for their inspiring submissions and congratulations to the winners!

The results are in: The Neo4j Leonhard Euler Idea Contest, with US $10,000 in prizes, has drawn to a close and the winners were announced at NODES 2021 by Emil Eifrem, CEO and Co-Founder of Neo4j.

A record number of innovative, thought-provoking, and inspirational ideas were submitted from around the world, and I wish to thank each one of you wholeheartedly for taking the time to submit your ideas.

The primary goal of the idea contest was to excite and inspire developers, students, technology enthusiasts, and hackers to see the innovations, applicability, and feasibility possible – with graph database and GraphQL Library across different use cases – and present their work to a thriving global community of graph enthusiasts and developers.

The contestants also got early access to our free cloud offering Neo4j Aura to build their GraphQL solutions, which is now available to everyone!

That goal was reached, and we couldn’t be more excited and impressed. Thanks for making the idea contest a roaring success.

Neo4j GraphQL Library- Mechanics

The Contest by the Numbers

We launched the idea contest on Apr 27, 2021, with the general availability (GA) of Neo4j GraphQL Library, and closed submissions on June 7, 2021. During those 41 days, more than 300 developers, data scientists, and professionals from 58 countries registered and submitted their ideas for the Leonhard Euler idea contest. We received 28 qualified, stunning idea submissions from which three prize winners and five most creative ideas were selected.

“If I have a thousand ideas and only one turns out to be good, I am satisfied.” – Alfred Nobel, of the Nobel Prize [and probable graph enthusiast]


The Leonhard Euler Idea Contest winners were selected by a stellar panel of judges from across the Neo4j Graph Database industry. They evaluated each submission on originality of idea, complexity of implementation, feasibility of solution, and whether the idea makes developers’ and people across the globe’s lives easier. Here’s our panel of brilliant judges:

The creator of Developers.Zed, Kacha Mukabe’s inspiration in his own words: “Developers in Zambia (in Southern Africa) tend to be overlooked by local people hiring simply because they are not as visible. Most dev work is outsourced and I want to make it a little easier for employers to find developers locally.”.
