Innovate at the speed of light

Sohjo Hacks is a 30-hour international hackathon where developers, designers, and innovators build working prototypes and web apps for real research and commercial challenges.

Build something heavy

The hardest challenges don't get solved in weekend projects. They take years. Unless you put the right people, the right tools, and 30 uninterrupted hours in the same room. With AI-assisted development, a team of ambitious builders can go from a hard problem to a working solution faster than many companies move in a quarter. 30 hours. Enough to ship something that changes your next chapter.

Challenges

Pilot project for UEF labs

University of Eastern Finland

Pitch a pilot project idea that pairs a real business problem with the research expertise and lab infrastructure available at UEF Joensuu Campus — and turn it into a concrete collaboration plan.

The problem:

Many innovative companies have R&D needs but lack access to the specialized lab environments, testing facilities, and domain expertise required to move ideas forward. At the same time, UEF Joensuu Campus sits on a wide range of underutilized RDI capabilities (from photonics and sustainable chemistry to immersive XR technologies and natural resource research) that could accelerate company innovation. The gap between business ambition and research capacity remains untapped.

What you'll build:

A compelling pilot or proof-of-concept proposal that identifies a specific business or customer problem, maps it to one or more UEF Joensuu labs, and outlines how a joint RDI project, contract research engagement, or co-funded research partnership could be structured. The strongest submissions will articulate clear novelty, a path to business value, and a realistic collaboration model with UEF.

Prizes:

  • €1000
  • €700 in intellectual property consultation from Genip Oy
  • Future collaboration opportunity

Skill gap detection system for enterprise learning

Valamis

Build a proof-of-concept that assesses where individual employees actually stand in their skill development and surfaces targeted learning to close the gaps.

The problem:

Companies that define what skills each role requires still rarely have a clear picture of where individual employees actually stand against that list. Learning gets assigned by role, not by need. Gaps go undetected until they surface somewhere costly.

What you'll build:

A system that identifies genuine skill gaps at the individual level and maps them to existing content. The hard part isn't recommending content once a gap is found. It's the identification itself. Job titles, training history, and self-assessment all fall short. Your solution needs a better signal. Format is open: a web app, a Slack bot, a browser extension, or an ambient layer inside an existing tool.

Prizes:

  • €1,000
