“Competent, reliable, friendly: That immediately comes to mind when I think of you! As someone who was not directly involved in recording the process, I had the opportunity to see what a strong development was taking place in the project, which also drew positive circles beyond that. The first-name culture you have established in the project alone has changed a lot in collaboration across the company.
People who had nothing to do with each other got into conversation through you and noticed how much they actually have to do with each other. You have encouraged us to systematically think about how we currently work and how we want to work in the future — individually and as Otto Wulff.
You not only worked through them, but you were committed and wanted to get the best out of it for us. You've done that — with a very warm and personal way of moderating and treating you. But as I said: It wasn't just nice, we also really brought something out on the road together. I hope that it works out again for the next projects!”

“Pragmatic, agile and competent — this is how the 55BirchStreet team, together with their strong partner network, helped us take the first steps into new digital territory.
The result? The go-live of the online customer portal as MVP after just 3 months and numerous ideas and innovative approaches to successfully drive our digital transformation forward.
Thanks 55BirchStreet!”

“What was I looking for when I found 55BirchStreet? I wanted to complement our own expertise with an external perspective and implementation power during the professional and organizational transformation of my area.
In addition to professional sparring on strategic issues and operational project management, I needed powerful support that was not afraid to effectively implement pretty chart decks operationally. And it was important to me that the mindset was right for the collaboration and ultimately the project to be successful. This means that external support should feel like temporary colleagues who, in addition to valuable professional expertise, also have a high level of emotional intelligence.
Technically, you left no doubts when coordinating your potential assignment. And with your understanding of people and your critically constructive yet humorous manner, you are always able to dock in my organization and yet highly professional — for me, this combination is one of your greatest strengths. The professional and personal added value that you bring was and is extremely high. I am looking forward to continuing such successful and valuable cooperation!”

55BirchStreet was recommended to us internally within our organisation, and I am delighted to now be able to pass on this recommendation myself.
We asked 55BirchStreet to hold a full-day workshop with the aim of bringing together two heterogeneous IT teams, consisting of around 40 internal and external employees, and addressing the topic of collaboration in more concrete terms.
What immediately struck me as positive was that 55BirchStreet didn't just hold a workshop. Julius and Anne took responsibility from the outset and guided us, where it made sense and was necessary, through the planning and preparation. Even though we didn't know each other, we immediately felt confident that our teams were in good hands.
Their proactive approach was also evident on the day of the workshop itself. Their goal was to lay the foundation for us to really move forward after this one day. Julius and Anne repeatedly challenged us to show commitment and to take responsibility with confidence and a positive attitude.
My teams described the workshop as varied, entertaining and practical – the right mix of input, personal approach, intensity and fun. They developed an understanding for each other and realised how much we actually have to do with each other our this areas.
At the end of the day, it was clear that the will to move forward together is alive and well.
That is why we give them our wholehearted recommendation. Thank you!

“When revising our sales strategy, we deliberately adopted an “AI-first” approach. With 55BirchStreet, we have found a partner who not only knows how to professionally moderate strategic issues but also uses modern, creative methods and tools to identify new ideas and potential. The process was very clearly structured, the methodology was well-founded, but what really made the difference was working together: With a lot of empathy and ease, you accompanied us through challenging discussions and decisions — and repeatedly built bridges between strategy and implementation. Your in-depth knowledge and application expertise in the area of AI has raised our strategy work to a new level, in which we were able to increase both the quantity and quality of results in an extremely lean manner. In this way, we were able to identify ideas, develop personas, evaluate business models and check feasibility — in a fraction of the usual time. Thank you for your commitment and the positive, uncomplicated collaboration! We are very pleased about this future-oriented partnership. ”

“I have 55BirchStreet as part of an ongoing exchange series on the topic of the present and future of project management: “Are projects dying like dinosaurs? “got to know. In my role as IT project manager at HAMBURG WASSER, I was able to experience Lena and Anne in particular with their project management expertise with other in-house project managers from Beiersdorf, Union Investment and Reemtsma. They brought commitment and structure to our workshops and provided substantive impulses, which enabled us to take on new perspectives together and develop appropriate courses of action from them. And the best side effect: It's fun to talk to them because they are just the way they are.”

“Anne, Martin and Ben have supported us throughout the company-wide SAP implementation right from the start and made the project a success. Whether as project manager, risk manager, PMO or test management — with their professional expertise, hands-on mentality and interpersonal skills, they have worked with us to keep the project team on track for years.
They gave us time for the relevant topics and were always by our side as a strategic sparring partner, even in critical project decisions.
Great team! Good job, well done!”

When I think of working with 55BirchStreet, I think of approachability. From the very beginning, it was not a classic consultant-client relationship. Instead, from day one, we were a close-knit team working towards a common programme goal.
Their ‘golden eye’ was particularly valuable, as was their ability to see challenges from a different perspective and thus visibly improve the quality of our project results, both strategically and operationally.
With their skills and expertise in managing projects, programmes and change in organisations, Anne and Julius provided the unfiltered feedback and clarity that the programme needed – without overwhelming the organisation.
In addition to their coordinated roles, they kept track of many issues in parallel, proactively brought them up and dealt with them as requested. This was a great relief to me in particular as programme manager.
The results of their work? High quality, developed with meaning and understanding, always on time. You can tell that they really care about getting the best for their clients and don't just reel off a standard script.
Especially in intensive transformation phases, it is invaluable to have partners at your side who work on an equal footing, promote enthusiasm within the team and make it fun.
I can wholeheartedly recommend working with 55BirchStreet.

“In my previous position as Director of Operational Excellence Europe, we initially aimed to introduce a standardized project management toolbox to better structure our projects. But working with 55 made it clear that we needed to go more broadly to get real value. In the end, we jointly standardized the company's entire project management methodology, including processes, roles and project documentation, as well as implemented the Europe-wide introduction of PPM software.
In their role as project manager, 55 has not only proven that they are able to manage a high level of complexity and always manage interdisciplinary teams on equal footing with a small pinch of humor, but they have also supported with their expertise and shown how a project can be successful through a targeted change and communication strategy.”

As division manager responsible for the Technical Products & Sourcing department (formerly Quality Development) at bonprix, I brought the 55BirchStreet team on board as part of the digital transformation of our global technical product development. In addition to designing future cooperation processes, 55BirchStreet was significantly involved in the development of a new, more efficient organizational structure and optimized the division of labor with the Otto Group's internationally active sister organization. Based on an assessment of the current situation, the desired target state was designed and the transition process was developed and implemented — on time and within budget.

Together with 55BirchStreet, we wanted to find out how we can truly get artificial intelligence moving within our company. Instead of only talking about strategies, we got straight to work. Following preparatory sessions on an AI-first mindset and use-case identification, we put ten selected use cases into practice during a one-day hackathon.
Around 40 colleagues from Digital Product Management, Content Marketing, Business Transformation, and Organization participated. Their prior experience with AI varied widely, yet you managed to bring everyone along. This made it tangible how AI can be meaningfully used in day-to-day work.
The hackathon helped us develop a clearer picture of which opportunities are already practical and valuable for us today and which steps we want to take next. We were able to assess which use cases have potential for us and where the business impact is not yet proportionate to the effort required.
With 55BirchStreet, we had a sparring partner at our side who supported us with clear input and structured deep dives. The exchange between an external perspective and our own experience helped us define our next steps in the AI context more clearly.

Wir haben 55BirchStreet in einer für uns hochkomplexen, blockierten Phase mit erheblichen Auswirkungen auf die gesamte Organisation in unser Unternehmen geholt. Mit Annes Begleitung kam spürbar Bewegung und Klarheit in diese Situation, durch konsequent strukturierte Prozessführung, präzise Interventionen, eine klare Haltung und die richtigen, auch unbequemen, Fragen.
55BirchStreet hat uns nicht nur durch diesen sensiblen Prozess geführt, sondern echte Entscheidungsfähigkeit hergestellt und Menschen befähigt, Verantwortung zu übernehmen. Bis heute erleben wir 55 als wertschätzenden Challenger an unserer Seite, und arbeiten auch in weiteren anspruchsvollen Themen mit dem Team zusammen. Dabei nehmen wir immer das gleiche Selbstverständnis wahr: Organisationen so zu stärken, dass diese auch in herausfordernden Phasen klar, verantwortungsvoll und wirksam bleiben.
Egal, welches Thema mich umtreibt: Ich weiß, ich kann 55BirchStreet anrufen und mich darauf verlassen, dass wir eine tragfähige Lösungsrichtung entwickeln, und ich gestärkt in die nächsten Schritte der Umsetzung gehe.
