Impact of the project for our customer

From Frustration to Growth

Before partnering with MarsBased, Trompo had a rough start. Their first attempt with another agency resulted in a platform that was plagued with performance bottlenecks and technical issues.

This meant the client couldn’t focus on their business goals and was stuck fighting with the product instead. Our mission was to change that, and we did. Today, Trompo’s team is free from software headaches and focused on what matters most: building their business and growing their market.


Results

Trompo is more than just another marketplace, it’s proof that small businesses can compete if they’re equipped with the right technology. By combining lean infrastructure, smart monetisation experiments, and a stable foundation, Trompo is now set up for sustainable growth.

As a bonus, this project helped us polish our MarsBased Rails API and Next.js templates, strengthening our toolkit for future clients.
