Shaka-kachi Week: Hacking for Social Value with SMBC

 

In a bold move to blend tradition with innovation, Sumitomo Mitsui Banking Corporation (SMBC) teamed up with Kreativdistrikt to bring the concept of Shaka-kachi — social value creation — to life through a series of dynamic hackathons. Spanning three global financial hubs — London, Frankfurt, and Dubai — Shaka-kachi Week invited young talent to tackle real-world challenges at the intersection of finance, technology, and ESG. With the support of expert mentors in Design Thinking and Agile, participants co-created actionable solutions in a fast-paced, hybrid format that bridged cultures, disciplines, and mindsets. The result: not just innovative ideas, but a powerful demonstration of how banking can embrace purpose-driven innovation.

The Hackathon Challenge

Participants engaged with some of the most pressing challenges in financial services — from ESG-aligned investment strategies and sustainability-related issues to AI in finance, data ethics, and fintech innovation. The trainings aimed to develop forward-thinking skills that equip participants to tackle these complex, real-world problems with clarity and purpose. The solutions proposed were not only innovative but also pragmatic — designed to be effective, regulation-aware, and tailored to real banking needs. Teams worked to find intervene areas, assess risk-prone zones, and propose approaches grounded in operational feasibility. Some of the specific challenge areas included decarbonisation, poverty and inequality, internal financing priorities.

The Right Approach To Find The Best Solution

 Pre-Hackathon Phase

Open call with global reach with an Online application where participants shared a concept summary submission, and we proceeded with the selection of diverse, high-potential participants and then started the warm-up webinar to align expectations and introduce key themes

During the Hackathon

We placed two expert mentors at the core of the participant experience: A Design Thinking coach guided participants through ideation, problem-framing, and user validation and an Agile coach helped teams rapidly iterate, manage workflows, and deliver functional outputs.

Hybrid Setup

This hackathon took place In-person production in 3 cities with a  fully supported virtual participation and a Real-time online mentorship with online tools (Slack, Zoom, Miro)

Ideas That Inspire Action

Kreativdistrikt proposed and executed “Shaka-kachi Week,” a series of three interconnected hackathons hosted in London, Frankfurt, and Dubai. Each event was hybrid by design, allowing for online participation and global accessibility. However, the magic didn’t come from the format alone — it came from the experience of architecture itself.

Each hackathon was framed as a journey, beginning with a warm-up phase where applicants submitted a concept summary and joined an online briefing session. From there, selected participants were grouped into teams and immersed in a 12-hour creative sprint supported by two lead mentors: one expert in Design Thinking and the other in Agile methodologies. These mentors didn’t just guide from the sidelines — they actively co-facilitated team development, offering structured workshops, toolkits, daily check-ins, and pitch refinement sessions.

By the end of each hackathon, every team had crafted a concise concept summary, a compelling pitch deck, and, in some cases, functional prototypes — all presented live to external experts.

Solutions Were Strategic and Pragmatic.​

Participants tackled some of the most pressing and forward-thinking challenges in financial services, from fintech innovation and digital transformation to ESG-aligned investment strategies, AI in finance, and data ethics. The problems were real, the solutions were imaginative, and the stakes were high — with each team aiming to make a tangible contribution to the future of socially responsible finance.

 

The Impact

Shaka-kachi Week helped SMBC position itself as more than a bank — as a global player investing in the future of people, planet, and prosperity. It unlocked fresh thinking from a generation eager to engage with meaningful work and proved that hackathons can do more than build prototypes — they can build community. The project also sparked internal discussions at SMBC around future talent engagement strategies, with Shaka-kachi Week serving as a model for future initiatives.

Kreativdistrikt managed the entire lifecycle of the hackathon series: from creative concept and challenge design to participant recruitment, content creation, logistics, and full event production. We crafted a unified brand identity for Shaka-kachi Week, coordinated mentorship and jury panels, built hybrid facilitation tools, and ensured a smooth, inclusive experience for both in-person and online participants. Post-event, we delivered media materials, reports, and strategic recommendations.
