Katarzyna Majer-Hola
COO and CFO at MIXD

She handles the financial and legal matters of the company and is responsible for the overall organization of both the projects and the studio's operations. She is a graduate of Wrocław University of Science and Technology, majoring in Architecture and Urban Planning. From her second year of studies, she began applying the knowledge she gained in practice, working for various architectural firms: first small local studios and then larger nationwide ones. It quickly became clear that her strength lay in effective project management.

They divide their responsibilities according to their strengths: "Piotr is responsible for acquiring clients, new business, and maintaining the quality of conceptual projects, while I handle the execution of these projects and their organization. Moreover, we complement each other well in making tough decisions: Piotr often has very ambitious, far-reaching plans, which I then confront with reality. This ultimately gives us a better, more comprehensive perspective on the matter and leads to better decisions."

She enjoys working with people and refining the design process: finding the best and most effective way to develop the various phases of projects, from the preliminary phase to final oversight. In the design process, she is fascinated by the initial phase, where pre-concepts emerge during brainstorming sessions and discussions. Her favorite projects are mid-scale hotels because they usually provide designers with more creative freedom and opportunities to utilize interesting design and build a strong storytelling than luxury projects.

Associates

Marta Jakubas
Associate, Hospitality

Marta Jakubas, an Associate in Hospitality, leads key hotel projects for MIXD in Poland, Europe, and Central Asia. She graduated from the Academy of Fine Arts in Kraków, specializing in Furniture Design, and studied in Paris at ESAG Penninghen through the Erasmus program. Interested in sustainable design, she dedicated her master’s thesis to this topic.

Marta began her career designing interiors for individual clients but later shifted to public interior design. “I moved from Krakow to Wrocław and started with MIXD. Three years later, I know it was a fantastic decision,” she says.

Regarding the MIXD slogan #newworldofhospitality, she highlights that it focuses on hospitality and experience design: finding new patterns, design solutions, providing attractive stimuli, and evoking emotions. “We base our projects on authentic stories, draw the best from local culture, and infuse it into our designs. We seek luxury in fundamental values like tranquility, closeness to nature, and sincerity.”

Małgorzata Grzechowiak
Associate, Procurement

Having studied at universities in Italy, Spain and Poland, Małgorzata thrives in transcending rules and genres. Before engulfing entirely in interior projects for the hospitality sector, she started her design career as an architect. Małgorzata worked in a number of award-winning practices, including Bjarke Ingels Group in New York and Büro Ole Scheeren in Beijing, where she has been involved in many prestigious projects across Europe, Asia, the Middle East and the United States. Not afraid of the chaos of creation, but rather thriving in it, Małgorzata often draws inspiration from unexpected fields, from fashion to fine arts. She joined MIXD in 2020 and currently works as a Senior Design Manager, leading hospitality projects from concept through to delivery. In parallel, as an Associate in Procurement, she focuses on ensuring that projects are realized exactly as envisioned — overseeing material selection, quality, and execution with precision and attention to detail.
