Community events: designing a hackathon

A community hackathon is a short, structured event where SMEs, makers, students, mentors, researchers and facilitators work together on real business or ecosystem challenges. In FABRIX Athens, the method was used through Seam the Change to connect policy questions, circular fashion needs, mentoring, prototyping and public pitching into one practical community process. This entry offers a light and generic SOFFA/FABRIX version for future facilitators who want to organise a simple hackathon without reproducing the full proprietary SOFFA event model.

What is a community hackathon?

A community hackathon is an intensive co-creation event in which participants form teams around real challenges and use a short time window to design, test and present early solutions. In a textile and fashion ecosystem, the method can help businesses explore circular services, upcycling models, digital tools, traceability, sustainable materials, repair, resale, take-back schemes, production partnerships and new ways of working with local actors.

Key objective

The key objective is to move a community from discussion to action by turning a challenge into a prototype, a collaboration idea, a service concept, a pitch, a roadmap or a next-step partnership. The method is most useful when SMEs already have concrete needs and when mentors can help them translate these needs into realistic next steps.

Who should participate?

A practical hackathon normally needs a small organising team, SMEs or idea holders, facilitators, mentors, students or young professionals, designers, makers, researchers, policy actors and a small jury or feedback panel. The organiser should keep the group mixed, because the value of the method comes from matching different types of knowledge rather than keeping participants inside their usual professional circles.

What do you need to organise it?

The minimum set-up includes a venue with working tables, Wi-Fi, projector, microphones if needed, a registration form, GDPR and signature list, an agenda, name tags, flipcharts, sticky notes, basic prototyping materials, a mentor list, a team formation process, a pitching template and a clear communication campaign. It is useful to prepare a simple challenge form in advance so that teams can identify what they need help with before the event starts.

Simple process

The process can be organised in five steps: first, define a theme and collect real challenges from SMEs; second, open the event with context, platform onboarding or a short self-assessment; third, organise an Ideas Agora where people present ideas and form teams; fourth, run mentor clinics and working blocks so that each team can refine its concept; fifth, close with a short pitching session, jury feedback and follow-up matchmaking.

How did we use it in FABRIX Athens?

In FABRIX Athens, the method was applied during Seam the Change, the Athens Fashion Hackathon, which was co-organized by SOFFA, Impact Hub Athens and Ten Million Hands and co-curated by Fashion Revolution Greece. The wider sequence included a policy dialogue on 11 November and two hackathon days on 12 and 13 November 2025, where participants used policy challenges, the FABRIX self-assessment tool, team formation, mentoring clinics and a final pitching showcase to explore circular fashion solutions.

The FABRIX version placed special emphasis on needs-based matchmaking. Idea holders explained both what they were building and what they needed, mentors were matched according to areas of expertise, and the final pitches made the learning visible to the wider ecosystem. The method showed that hackathons are most effective when they are not treated only as competitions, but as community-building and problem-solving tools that continue after the event through follow-up conversations and platform links.

Expected outputs

Typical outputs include team concepts, pitch decks, mentor notes, ecosystem maps, new partnerships, photos, participant lists, communication material, platform feedback and a short report summarising what was learned. The most important output is not only the winning idea, but the new network of people who now understand each other’s needs and can continue working together.
