We continue with our “Inspired by…” series at Nousmedis! And this time, we bring you a story that has us completely in love (and not just metaphorically). Because if there’s someone who inspires us daily with her energy, professionalism, and warmth, it’s Justyna Tomaszewska. The collaboration between Sales Layer and Nousmedis has been fundamental in this love story.
Justyna is one of those people who make everything seem easy. From the first moment we started working with her, we were amazed by her work ethic, commitment, and above all, her generosity in sharing knowledge and providing solutions. She is someone who is always willing to help, who builds real relationships, and who understands that success is not just about business, but about trust, collaboration, and a deep passion for what she does.
She describes herself as a Polish woman in Valencia, having built an impressive career path. From working at industry-leading companies like EDICOM and Amazon Web Services, she now holds the role of Strategic Partnerships Manager at Sales Layer. But beyond her title and experience, what truly makes her special is her way of seeing the world: with curiosity, a desire to learn, and a genuine interest in connecting with people.
In this interview, we’ll learn more about her journey, her vision for working with partners, and industry trends. But we’ll also get to know her on a personal level: how a Polish woman ended up in Valencia and why we are all captivated by her charm.
Let’s dive into Justyna’s story, an authentic source of inspiration.
About Justyna Tomaszewska
Could you tell us a bit about yourself and your career path before joining Sales Layer?
I studied Hispanic Philology and later completed a master’s degree in business management, as I have always been passionate about the world of technology and business. I came to Spain for an internship, and what was initially supposed to be temporary ended up marking the start of my professional career.
My first “serious” job was at EDICOM, an international company based in Valencia specializing in electronic invoicing and VAT compliance. It was a period of immense learning, working with some of the world’s leading companies. As the person responsible for opening Central and Eastern European markets, I understood the fundamental role that local partners play in international expansion. That experience shaped my approach to strategic relationships.
Afterward, I joined Amazon Web Services (AWS), which was an intense phase, where I saw how, with the right strategy, a network of partners can multiply the impact of a solution and take it much further than it could go alone.
And now I am at Sales Layer, a company whose vision and values I deeply resonate with. Here, as a Partner Manager, I can apply everything I’ve learned and, most importantly, continue building strong, human relationships based on real collaboration. For me, partners are not just a distribution channel; they are an extension of the team and deserve our commitment to working for and with them.
What led you to specialize in strategic partnerships management?
I love working with partners, and I am convinced that they are key to sustainable business growth. That’s why specializing in strategic partnerships management was a natural path for me. I try to bring a lot of energy and dedication to these relationships because I understand their value: partners provide direct market feedback, help improve your product, generate business, build more effective marketing campaigns, and, most importantly, allow you to scale in a much smarter way.
Sometimes, from the outside, it’s not well understood, but working with partners is neither automatic nor immediate. It’s a process based on trust, continuous communication, and realistic expectation management. It’s not about seeing partners as a deal-making machine but about building a win-win relationship where both parties feel heard, valued, and committed to a common goal. Only then does it make sense.
I enjoy both working with new partners—seeing how they gradually gain confidence in our solution and team—and fostering long-term relationships. In fact, the greatest impact often comes from consolidated partnerships, where we have already walked a path together. I’m highly motivated by preparing joint campaigns, exploring new synergies, and working on ambitious yet realistic growth plans.
For me, that’s the most beautiful part of this role: We continue with our “Inspired by…” series at Nousmedis! And this time, we bring you a story that has us completely in love (and not just metaphorically). Because if there’s someone who inspires us daily with her energy, professionalism, and warmth, it’s Justyna Tomaszewska. The collaboration between Sales Layer and Nousmedis has been fundamental in this love story.
About Sales Layer
For those who don’t yet know Sales Layer, how would you describe your mission and the value you provide to clients?
Sales Layer is a PIM (Product Information Management) software provider that helps companies centralize, optimize, and distribute all their product information from a single platform.
Our mission is clear: to make life easier for teams managing complex product catalogs, helping them work more efficiently and launch products to market faster and with higher quality.
We provide value to different profiles within a company. For manufacturers, we are a key solution for maintaining complete control over their product data, ensuring that information reaches all sales channels (whether marketplaces, distributors, or print catalogs) accurate and up to date.
For marketing teams, we provide an agile tool that enables them to launch multi-channel campaigns faster, with optimized and error-free content.
Ultimately, Sales Layer is that “single source of truth” that allows companies to grow, scale into new markets, and improve the customer experience through smart product data management.
What sets Sales Layer apart from other solutions or approaches in the market?
What differentiates Sales Layer from other solutions in the market is our clear focus on B2B companies and the agility we offer. We are a PIM designed for manufacturers, distributors, and brands managing complex catalogs and needing fast results.
Our implementation is very agile (we’re talking weeks, not months), provided, of course, that the client is engaged in the process. Magic doesn’t exist, but with good commitment, we’ve even set up a complete catalog in just two days.
We also stand out for our intuitive interface, designed for non-technical profiles. This greatly facilitates adoption across different teams, from marketing to product management. Thanks to this simplicity and efficiency, our clients typically see an 80% improvement in productivity and a 30% increase in conversions, accelerating ROI as well.
And something our clients constantly highlight, both in conversations and on platforms like G2, is the quality of our support and the work of our Customer Success team. This is something they truly value, and it makes a difference in their day-to-day operations.
The best part? This isn’t just what we say: it’s what our clients and, in my case, the partners I work with every day confirm. They are the ones who tell us that we genuinely stand out from other solutions in the market seeing how mutual effort translates into real results.
About Sales Layer & Nousmedis
How did the collaboration between Sales Layer and Nousmedis begin?
Well, as your own CEO, Javier Gómez said, it all started with a paella… so you can already imagine that the collaboration between Sales Layer and Nousmedis started off with a great taste 😄.
The truth is, we were collaborating long before I joined the team. I think the company was still just the two co-founders, Álvaro and Ibán. And since then, the relationship has grown naturally and steadily. Today, we share more than 30 clients and continue building new projects together.
I think one of the greatest strengths of this collaboration is how well we complement each other. Sales Layer provides the PIM solution that centralizes and organizes product data, while Nousmedis brings its highly specialized expertise in catalog automation with EasyCatalog and InDesign. Thanks to that know-how, many of our clients can transform their data into commercial materials and catalogs in a much more agile and professional way.
What would you highlight about the relationship between Sales Layer and Nousmedis as partners?
Without a doubt, the foundation it’s built on: trust, mutual respect, and a shared vision. Beyond the technical aspects or the projects we’ve worked on, what truly makes the collaboration with Nousmedis work so well is that we have aligned goals: growing together, delivering real value to clients, and building solid, long-term relationships.
Of course, as in any relationship, there are times when we need to pause, refine strategies, find balance, or reach compromises. But the important thing is that there is always a willingness to listen, to understand each other, and to find common ground. And for me, that intention to build together is what makes the difference in any partnership.
It’s a collaboration with real communication, commitment, and a desire to improve. And you can see that both in the results and in the day-to-day teamwork.
In your opinion, what benefits has this collaboration brought to both parties?
The collaboration between Sales Layer and Nousmedis has been highly beneficial for both parties, and it has developed in a very natural way.
On one hand, thanks to Nousmedis, we’ve been able to reach many clients who not only needed a PIM solution but also a more comprehensive service: catalog automation, design, integration with tools like EasyCatalog and InDesign… Services that perfectly align with what we offer at Sales Layer and significantly increase the value delivered to clients.
On the other hand, we provide the technology and flexibility of the PIM, allowing Nousmedis to complement its offering with a solid, scalable, and easy-to-implement solution.
Podcasts & future projects
We know you have a podcast. What inspired you to start it, and what is its main focus?
Yes, I have a podcast called Sales Layer and Partners Chat Cast, although I have to admit I’ve neglected it a bit this quarter… I need to get back to it soon 😅. I’ve been caught up with so many things that I haven’t had time to record new episodes. But it’s a project that excites me a lot.
It all started last year when I was invited to participate in a podcast about partnerships. I loved the experience, and since I’m always restless, I thought: why not launch my own? At first, I had a lot of doubts, especially because I don’t record in my native language, Polish. I do it in Spanish and English because I work with partners globally, and that was a challenge. But I went for it, and honestly, I’m really enjoying it.
The podcast’s focus is clear: giving visibility to our partners. It’s not about talking about how great Sales Layer is but about listening to the partners—usually CEOs or senior executives—who share their experiences, challenges, lessons learned, and the services they offer.
These are short, 20-minute chats where we aim to really understand each company’s profile. Interestingly, the first episode I recorded was with the CEO of Nousmedis, which made for a very symbolic and special start.
What insights have you gained from the podcast that have impacted your professional vision?
The podcast has undoubtedly given me several key insights that have had a direct impact on my professional vision. The most important one is that, even though we all work within the same ecosystem, each partner has a unique story, a different way of seeing the business, and distinct challenges. Listening to those stories firsthand has made me even more aware of the importance of tailoring our collaboration to each partner instead of applying a one-size-fits-all approach.
It has also helped me see more clearly the immense value that partners bring—not only to Sales Layer but also to the end customer. In the day-to-day rush, it’s easy to lose sight of the huge impact they have on each project, and the podcast has allowed me to reconnect with that reality from a more human perspective.
And finally, it has reminded me how powerful it is to simply listen. Giving partners the space to tell their story, without interruptions or steering the conversation toward commercial topics, fosters deeper relationships based on empathy and trust. In the end, that’s what makes the difference in any partnership strategy.
Are there any upcoming projects or initiatives that excite you and that you can share with us?
Yes! The first quarter of the year has been intense but also incredibly exciting! We’ve been working hard on improving the way we collaborate with our partners. We’ve structured our processes more effectively, planned many more joint campaigns, and our partner-dedicated team is growing, which is a very positive sign.
Additionally, we have launched a new Partner Program that allows us to provide more support, visibility, and tools to our partners, adapting better to their profiles and needs. This initiative helps strengthen collaboration even further and build more solid and effective relationships.
So yes, a lot of great things are happening, with huge potential. We’re laying a strong foundation to continue growing together, with partners as a key part of this evolution. And personally, I’m really excited to see how this year unfolds and everything we can achieve together!
Strategic vision and emerging trends
From your role at Sales Layer, what trends do you currently observe in strategic partnership management?
The first trend, and perhaps the most obvious, is that companies are beginning to understand that partners are not just “sales channels” but actual extensions of the business. There is a shift in mindset: the focus is now on building more collaborative relationships based on trust, transparency, and mutual value.
I also see that partnership management is becoming much more professionalized. It’s no longer enough to just sign an agreement and wait for results. Companies are increasingly investing in structuring their partner programs properly, providing training, support, joint campaigns, and real resources to help partners grow. And this is a positive development, as it raises the level of collaboration.
Another clear trend is the growing importance of co-marketing and shared content. Brands want to communicate together, share real success stories, and build trust through the ecosystem. This is where joint campaigns and collaborative projects have immense potential.
Finally, I would highlight the use of data to optimize these relationships. Measuring partner impact, analyzing which types of collaborations yield the best results. This all helps in making more strategic decisions.
Justyna’s recommendations
What advice would you give to someone starting out in partnership management or a similar role?
Honestly… I don’t really like giving advice 😅. But if I had to share something based on my experience, I’d say that to work with partners, you need to truly understand how important they are. It’s not just another role within the company—it’s a strategic part of growth.
You also need a lot of patience. Results don’t happen overnight. It’s a constant effort involving many conversations, coordination, and learning. Some campaigns turn out great, while others simply teach you lessons for next time.
And above all, you have to remember that this is about relationships. Just like with family, friends, or a partner: everything is built on communication. Regular meetings, whether in person or virtual, are key to keeping the connection alive. Managing expectations is also crucial: listening, aligning goals, and building together.
And on a more personal and fun note… Is there any series you’re currently obsessed with and would recommend?
Oof… I try not to watch series because I can’t stop at just one episode. If I start, I binge, so I prefer not to fall into temptation, haha 🙂
But if I had to mention my all-time favorites, I’d say The Big Bang Theory, Friends, and House of Cards. I know, nothing original, but they really hooked me back in the day.
Recently, I watched a movie that left a strong impression on me: Incendies. I think it was nominated for the Oscar for Best Foreign Language Film in 2011. It has a very powerful and complex theme. It’s not an easy film—it stays with you for days.
😍 👏 BRAVA 👏 😍 The Polish-Valencian fusion never disappoints.
