What geecon does

Geecon (legal entity 4GC Sp. z o.o., headquartered at Rynek Główny 28, Kraków, Poland) is a community-organized Java and JVM technology conference and training business founded in 2009. Its core product is the annual Geecon Conference held in Kraków since 2009 (with a separate Prague edition launched in 2022), drawing 800+ attendees, 50–65+ speakers, and 60–70+ sessions across Java, JVM languages, AI, Cloud, NoSQL, distributed computing, enterprise architecture, and software craftsmanship. The company operates a rotating venue model (Kraków, Poznań, Prague) hosted at Multikino Kraków and academic venues, anchored by deep partnerships with the Polish Java User Group (PJUG), Poznań JUG, Czech JUG, GiK, and Polish universities.

The portfolio extends beyond the main conference into Geecon Classes (year-round corporate and public training in software engineering, leadership, and best practices with expert trainers such as Kevlin Henney), Geecon TDD (a specialized recurring conference on test-driven development, BDD, and software quality), and Geecon 4 Kids (educational programming events for children). Revenue is generated through tiered ticket sales (1099–1199 PLN + VAT for full conference passes), paid workshops (349–899 EUR + VAT per attendee), corporate training engagements, and sponsorship packages starting at 1000 EUR. Distribution is concentrated through Java User Group networks and direct online registration via register.geecon.org and classes.geecon.org, with the 16th edition scheduled for May 2026 in Kraków.

Regional players

• Boiling Frogs: Polish software development conference held in Wrocław. Comparable community-organized Polish tech conference competing with GeeCON for Polish developer attendees and corporate sponsorships.
• JPrime: Annual Java conference held in Sofia, Bulgaria, organized by the Bulgarian Java User Group. Comparable regional Java-focused event serving the Balkan/Eastern European developer market alongside GeeCON.
• J-Fall (NLJUG): Annual Dutch Java conference organized by the Netherlands Java User Group. Comparable community-driven, JUG-backed European Java conference targeting professional developers and architects.
• JokerConf: Russian-based annual Java conference covering JVM technologies and software craftsmanship. Comparable Eastern European Java conference historically positioned as a peer to GeeCON in the regional Java events circuit.
• CodeteCon: Polish software development and IT conference series held in Kraków. Overlapping geography and similar Polish developer audience as GeeCON, though broader in topic scope (not Java-specific).

Direct peers

• Devoxx: The leading independent Java and JVM developer conference series in Europe (Belgium), featuring world-class speakers across Java, cloud, and emerging tech. Direct competitor for speaker talent, sponsors, and attendee mindshare in the European Java conference space.
• JAX: Major German Java, enterprise tech, and software architecture conference series. Competes with GeeCON for European Java developer attendees and corporate sponsors across the DACH and broader EMEA region.
• Spring I/O: Annual conference focused on the Spring ecosystem and JVM technologies held in Barcelona, Spain. Closely comparable to GeeCON in scale (mid-sized European Java conference), topic coverage, and community-driven organization.
• Voxxed Days: Series of smaller, single-day Java community conferences organized by the Devoxx team across multiple European cities. Directly competes with GeeCON for local Java developer audiences and provides an alternative sponsor activation channel.

Broad incumbents

• JavaOne (Oracle): Oracle's flagship Java conference, the original Java developer event held historically in San Francisco. Operates as a broad incumbent in the Java conference space with significantly larger budget and global reach than GeeCON.
