Robbert Winnemuller · Stars Agency · Amsterdam & Almere · 2006 – 2026
Twenty years behind the scenes of global hits.
Stars Agency developed and managed DJs, singers, producers and songwriters whose music reached the biggest artists in the world, and closed the deals that built lasting careers. Built on two decades of relationships, and an instinct for the opportunity others walk past.

The work
From first contact to signature, and everything in between.
Stars Agency was never a single-discipline office. As founder and director I combined lobbying, networking, marketing, mentoring and long-term strategy with full business management, worldwide touring, contract negotiation and international deal-making, leading a team of seven and an exclusive roster of up to nine artists and producers.
Under that guidance, DJs, singers, producers and songwriters delivered music to global artists. The work generated over five billion streams and views, and thousands of live shows worldwide, recognised with a Grammy Award-winning production and three Grammy nominations for singles and albums, one of which took the award.
Nothing was given up. It was handed over. My faith in Christ sets the terms now.
In 2026 I closed Stars Agency with gratitude. Building other people's careers for twenty years was a privilege. The experience, the network and the way of working come with me into what's next.
Guidance & development
Careers aren't closed like deals. They're built like people.
Mentorship
Mentored artists personally and commercially: daily career strategy, plan formulation, and the steady hand an artist needs between the highs and the lows.
Creative guidance
Selection of works and vocals, musical direction, and the development of each act's image as a musician, guiding every act toward the top of their potential and beyond their own expectations.
Leadership
Led a team of seven and an exclusive roster of up to nine artists and producers, overseeing administration, PR, marketing and HR, and outsourcing where specialists served the client better.
Growth & positioning
Data-driven marketing strategy, streaming and YouTube channel campaigns, and unique creative concepts for every release. Then positioning and selling each act to publishers, labels and booking agents.
Deals & partnerships
Negotiated at the highest level of the industry.
Major labels
Landmark agreements closed with Universal, Warner, Sony and Spinnin' Records, including the biggest newcomer deal in the Dutch and German music industry.
Brands & screen
Synchronisation deals arranged with Nissan, Heineken, Tomorrowland and multiple television series.
Live & touring
382 live performances a year negotiated and managed across the globe at the height of our booking agency years. Tours built worldwide from A to Z: routing, promoters, contracts, flights, hotels, visas and ground transport, so the act only had to think about the show.
Contracts & rights
Thousands of agreements negotiated, drafted and executed: recording and publishing deals, licensing and sync contracts, booking agreements, management terms and NDAs. Master rights and royalties structured to protect long-term income, with every clause read before it was signed.
Selected credits
A glimpse of the track record.
A selection from twenty years. Part of the work, including the Grammy Award-winning production, is bound by confidentiality. Full track record and references available on request.
Beyond music
A connector across industries.
The network was never a by-product of the work. Building relationships, and recognising the opportunity hidden inside them, is the work itself. It rarely stopped at the edge of the music industry.
Property & development
Buying and selling agent in the high-end property market for artists, producers and professional athletes. Acquired homes for artists and footballers, and personally developed two detached houses from A to Z.
International football
Brought Dutch national team players to the table with international football clubs and set up lasting collaborations.
Bollywood
Arranged video production teams and exclusive acquisitions for the management of A-list Bollywood stars.
International hospitality
Brought together international hotel owners from different continents, including a connection at government level, who now develop hotels together across borders.
In their words
What the people I worked with say.
I have known Robbert for a long time. He always had the great talent of getting the best out of people, bringing them together to set up co-operations and lead them with teamwork into success. I was particularly impressed by his ability to manage even the toughest clients, effortlessly. He always finds a solution, solving last minute challenges under pressure in a very solid way. And with his negotiation skills, he always got the best deal possible.
An excellent individual with passion for music and success. I have never met anyone else who is willing to help the growth and success of his talents. Working with him on many projects together was a pleasure, and everything was smooth when Robbert laid out the details of each booking. His feedback and advice on industry issues are always on point and I would definitely go to him whenever I need guidance.
One of the world’s leading artists asked me to become his personal manager, tour manager and personal coach. I declined the offer, to be there for my family. Trust earned at the highest level
What's next
Available for management and representative roles.
My strength is recognising opportunities across disciplines, and closing them strategically and commercially. What I bring to a company now is the same as what I brought to every artist: doors that open, people who grow into their best, and deals that hold. I am looking to put that experience to work for an organisation with a purpose worth serving: in music, media, sport, hospitality, real estate, or in the non-profit and public sector. Internationally, as an advisor, on an interim basis or in a permanent role. If that sounds like yours, I would be glad to talk.
Doors close and others open. Today I am planted as an estate agent here in the Netherlands, and I am grateful for it. I am not looking to move for the sake of moving. But where there is a purpose that asks for all I have built by His grace, I follow.
