Ontheside

Ontheside wanted to create a platform for athletes and fans, but had one main question: How should the platform be built? 

With this question on paper, we started the collaboration acting as feature developers, but took over the whole project as lead technical business partners. With this, we got the overall responsibility for the development of the platform. 

We assembled a team of experienced developers, designers, and tech architects (some in-house, other external) in order to be as efficient as possible and to deliver and move fast. 

Ontheside had no existing platforms, API, configurations, or software that needed to be connected to the new platform. Basically, we started from scratch. This might sound like a great thing but raised many questions regarding software choices and the overall technical architecture design. 

Ontheside knew they needed a flexible and scalable solution to future-proof the platform but needed to keep the costs low at the same time.  

This opened technical challenges during the development, and created a dilemma: Low-cost or high scalability? 

In the end, we created a cutting-edge stack including AWS cloud infrastructure, Kubernetes orchestration, and PostgreSQL database with type-safe Kysely queries. Our React-based Next.js frontend delivers lightning-fast performance with Tamagui's universal design system, ensuring a seamless experience across all devices. 

So, what does that mean? A platform that scales effortlessly, ships faster, and delivers experiences users love across every device. 

On the platform athletes can share rich content of their journey to the top. They can share pictures, meal plans, training schedules, coaching advice, nutrition tips, and gear guides that capture the whole experience of an athlete's life. 

In short; athletes share their stories and expertise, chase their dreams, and show us what’s possible. Fans explore sports, pursue their own goals, and support athletes along the way. 

As part of Ontheside’s commitment to athletes, 80% of sponsorship funds go directly to the athlete-creators. The remaining 20% is re-invested into the platform, building a global sports community where athletes and fans inspire each other to be exceptional. 

The platform launched in mid-May 2025, and invites have been sent out to athletes to start signing up. The team is now waiting and hoping for a successful sign-up rate. 

Ontheside emphasized the successful collaboration with Kruso, and appreciated the innovation, entrepreneurship, and ability to quickly set up a strong team. Therefore, we still act as technical business partners and keep improving the platform as well as the overall business from a technical perspective.
