From Mustang Marketing to Mits: How a marketing agency became a company that builds its own products

In 2010, Adam Terepora and Tomasz Gawłowski - a classmate from the Lublin University of Technology - founded Mustang Marketing.

Mustang Marketing was a natural outcome of their collaboration on several projects during their time as freelancers and stemmed from the combination of design and technical expertise.

Over the years, the Mustang Marketing team developed custom applications for departments at the Lublin University of Technology and training companies, as well as websites for businesses across the country. The agency also focused on supporting companies in the area of digital marketing and served as a subcontractor for Warsaw-based advertising agencies.

In 2017, we transformed Mustang Marketing into Mits. The name change stemmed from a natural evolution in our approach to working with clients, and this was further developed into the slogan “Make IT smooth.” Even back then, Mits focused on a seamless collaboration process so that the company’s clients would have constant communication regarding the work being done on their projects, and each task would be the result of an extended planning process combined with pre-implementation workshops.

Over the years, we have continued to work with both small and large companies. As Mits, we work for, among others:

• Perły
• UMCS,
• DTS System
• SpeakUp (Learning Systems Group)
• Politechniki Lubelskiej
• Fundacji Wolności,

by developing projects for them that are both visually and technologically sound.

Our expertise and skills are also recognized by other industry professionals. We also welcome collaborations with advertising agencies, interactive agencies, and software development companies:

• Mint Media
• Kerris Group
• 300.codes
• Artegence
• Sunscrapers

In 2024, we began implementing an EU project that resulted in Estimade.

Estimade is a tool that solves the problem of pricing services such as those offered by Mits, enabling faster and more accurate quotes. As a result, Mits gained a tool that shortens the process of creating quotes for clients to just a few dozen minutes, while also creating a product that is now offered to companies with a similar profile.

The development of Estimade has enabled Mits to acquire new competencies and begin transforming from a typical software house into a partner for companies, helping them grow both online and offline.

In 2026, we acquired a stake in a tech startup. From that point on, we became co-owners of HeroSwipe, an app that helps companies conduct A/B tests on their products and then enables them to quickly optimize those products across multiple sales platforms worldwide.

This was the result of the direction we had set a year earlier. It involves considering the possibility of collaboration and profit-sharing arrangements for our clients’ particularly promising projects, based on the profits generated. We believe that by combining the expertise we’ve acquired over the years with the commitment and dedication of our partners, we can achieve exceptional results together.

As a result, over the past few years, we have collaborated or are currently collaborating under partnership agreements with companies and websites such as New Level Sport, farmamarket.pl, and oleczeniu.pl.
