Guy Greenstein, Head of Engineering at Invisory, discusses the company's recent hackathon aimed at building integrations using Prismatic's embedded iPaaS. Invisory assists independent software vendors in navigating cloud marketplaces like AWS and Salesforce by providing a platform that centralizes data and functionality, allowing for efficient management of tasks such as listing and transacting. The hackathon served as both a learning experience and a proof of concept for using Prismatic, offering rapid troubleshooting and idea generation in a collaborative setting. Although the integrations developed won't be in production until later in the year, the event successfully established processes and familiarity with Prismatic, prompting the team to plan future hackathons to further enhance their integration capabilities. Greenstein emphasizes the flexibility and innovation that can arise in such events and plans to extend the duration in future iterations to maximize outcomes.
