Céleste Reumert Refn is an international trademark strategist, intellectual property expert and the founder of GRAND IPR®, a boutique intellectual property practice supporting scaling founders and visionary brand builders. Combining legal expertise with commercial strategy, Céleste has built a reputation for helping businesses transform trademarks from administrative necessities into valuable commercial assets. With a Master of Laws specialising in intellectual property from the University of Copenhagen and more than a decade of experience maintaining a 100% trademark registration success rate, she advises ambitious entrepreneurs preparing for international growth, investment and strategic partnerships. As AI reshapes how brands are created, protected and commercialised, Céleste has become an increasingly sought after speaker on AI, identity protection and intellectual property strategy.
Céleste’s legal career began as a legal intern at MAQS Law Firm, where she gained practical experience across commercial legal matters before developing a specialist interest in intellectual property. She later served as a Legal Consultant and Leader of the Administrative Department at Powerjobsøgerne Hovedstaden, further strengthening her leadership and operational expertise. Building on this foundation, she became a Specialist Legal Counsel in Intellectual Property Rights at Kunstnernes Retshjælp, advising on the protection of creative works and intellectual assets. Motivated by a belief that legal protection should empower innovation rather than restrict it, Céleste established GRAND IPR®, where she now works exclusively with founders building businesses beyond national borders. Her philosophy is rooted in the principle that creating something does not automatically guarantee ownership, making proactive legal strategy essential in today’s digital economy.
Alongside her legal practice, Céleste has earned widespread recognition for her contribution to intellectual property law. She was named Best International IP Specialist at the Acquisition International Legal Awards and also received the title of Best IP Lawyers UK from the same organisation, alongside recognition as a Leaders in Law Global Awards winner. She was a finalist in the Rising Star category at the Business Awards UK and has contributed to the wider intellectual property profession as a member of the Danish Society for Copyright. Expanding her influence further, she co-authored the book ‘Control Your Own Copyright, Trade Mark & More…‘, providing founders with practical guidance on turning intellectual property into long term commercial value.
Céleste is hired as an AI speaker because she addresses one of the most overlooked consequences of artificial intelligence: ownership. As AI makes it easier than ever to generate content, launch businesses and build personal brands, she equips audiences with the legal and strategic frameworks needed to protect what they create. Her presentations explore AI and identity protection, personal brand risk, strategic trademark architecture and international intellectual property, translating complex legal concepts into commercially relevant insights. Combining legal precision with practical business experience, Céleste helps organisations understand how to build resilient brands that remain valuable, defensible and investment ready in an AI driven world.
Céleste Reumert Refn is regularly booked to engage audiences at events, read their latest feedback below:
“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.”
“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.”
“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.”
“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.”
