About HackMeridianHackMeridian is a two-day builder event bringing together developers, founders, designers, and technical teams to turn ambitious ideas into working products on Stellar. The main event takes place October 25–26, 2026 in Lisbon, Portugal. There's more than one way into HackMeridian. Start where you are, find your people, find your idea, and find your way. 🚨 Apply today at HackMeridian.com. HackMeridian has two paths: Genesis: for first-time founders, emerging builders, domain experts, and multidisciplinary teams working on a new idea or early prototype. Scale: for experienced founders, product teams, developers, and startups with an existing product or advanced prototype looking to take it further. Experience does not need to be on Stellar.
