Origins

The co-founders ([Simon Kubica](https://simonkubica.com) and [Christian Iacullo](https://christianiacullo.com)) met in Sydney in 2016 through mutual friends. We were toying with the idea of starting a company at that point, but felt we still had a lot to learn from all of the tech companies springing up around us. Christian went to Canva, Simon went to Atlassian, and we spent about 5 years at each. Both companies turned out to be rocketships, building our skillsets and helping us grow through all of the talented people around us. Reflecting on our experiences in both companies, one of the clearest burning problems was how painful and fragmented planning was. So seven years later, we finally saw the opportunity to bring a product of our own into the world, starting with Index and then following up with our second product, [Alloy](https://alloy.app).
