Official Feedback From In-Person & Virtual Events
“Céleste has helped me in the process of having my trade mark registered, the logo and the company name Powerjobsoegerne.
It was a huge help to me, and I regret not knowing that such an option was possible from the beginning because the whole process would have gone faster and smoother.
I recommend to all start ups that they make use of Céleste’s skills in relation to the trademark registration - the process will be much swifter and you avoid having to deal with all the correspondence that comes with it.
Céleste has an enormous amount of professional knowledge and is highly devoted to her vocation” - Malene Gregaard Wilsly, Founder of Powerjobsøgerne
"Céleste gave a great talk at our Networking for Good event about trademarking. It was really interesting and engaging, and answered so many questions. It's clear that she has both a passion and deep knowledge of this field, which can be so confusing for so many.
What really stood out to me was her ability to simplify complex concepts and make them accessible to everyone. Her examples were relatable, and she provided practical tips that we could all take away.
And she also has an unbroken track record of 100% registered trademarks!
I highly recommend reaching out to Céleste if you have any questions about trademarking your brand or anything related to intellectual property." - Sindre Kaupang
"On January 23 2026, Céleste Athalia Reumert Refn joined our community for an “At the Collaboration Table” discussion on intellectual property, collaboration, and boundaries. We are an ecosystem of collaborators, and several of us came into the conversation skeptical about contracts and protection, often associating them with fear, control, or a loss of creative freedom.
She reframed IP as clarity rather than control, positioning it as something that actually makes it safer to share brilliance. Her message landed deeply: collaboration without boundaries doesn’t create freedom. It creates risk, resentment, and regret. You could feel the room change as she spoke, especially when she named that trust is relational while IP is structural, and that asking trust to carry what structure should hold is what breaks collaborations over time.
By the end, protection didn’t feel fear-based or restrictive. It felt expansive, like a container that allows creativity, generosity, and collaboration to flourish without exploitation or burnout. Céleste has a rare ability to make complex, intimidating topics feel human, practical, and empowering.
I recommend Céleste for communities, partnerships, collaborative teams, and entrepreneur networks, especially where people are co-creating, building public-facing work, or navigating partnership dynamics with an eye toward sustainable growth and integrity." - Kristen Toscano
"I have been running a female business network in Central London for 7+ years. Every month each group has a speaker on a business or personal development topic. As a person who runs two businesses, I’ve always been acutely aware of the importance of protecting my brand and have protected three names.
That is why I’ve asked Céleste to do a talk on that topic so that our members could become more aware of the importance of trademarking. Céleste shared some very valuable information both about the need for registering your Trade Mark, as well as the different possibilities you need to consider in the process. Céleste is clearly extremely knowledgeable and I wouldn’t hesitate to recommend her to anyone wanting to protect their brand." - AnYes van Rhijn
"I had the pleasure of witnessing Céleste deliver an outstanding presentation during one of our recent Impact Community events, and I was genuinely impressed by both her depth of knowledge and her engaging delivery style.
Her session on trademarking, especially framed through the lens of her own brand — GRAND IPR®️ — was not only informative but also deeply inspiring. She managed to simplify a complex subject while keeping the audience engaged and empowered to take action. It was clear she’s not only dedicated about her work but also about helping others navigate their own creative and business journeys with clarity and confidence.
Céleste brings a unique combination of creativity, professionalism, and heart into everything she does — a true asset to any community or project." - Jacek Zawieracz
