Leadership, Communication, and Collaboration

We train what remains uniquely human.

The more AI and new technologies change the way we work, the more important the things they cannot do for us become: leading people. Truly listening. Having difficult conversations. Delivering presentations that persuade. Resolving conflicts. Shaping change together. yuii develops leaders, employees and teams precisely where human skills make the difference.

Based in Berlin since 2011 – working with clients such as Flaconi, Shiseido and Grüner Punkt.

Where do you want to see change in your organisation?

Perhaps new leaders need to find their feet faster. Conflicts need to be addressed earlier. Employees need to communicate with greater impact. Or a team needs to navigate change more effectively. Start with what is not working well enough right now – and we’ll show you how we work on it.

01 Leadership Development Leadership starts before the title When people step into leadership for the first time, or experienced leaders face new challenges, expertise alone is not enough. We help them feel confident in their role and strengthen the skills effective leadership requires every day.
02 Communication Training Speak clearly when it matters When feedback does not land, conflicts simmer or difficult topics are avoided, collaboration suffers. We strengthen people’s ability to listen, speak plainly and handle challenging conversations constructively.
03 Public Speaking & Presentation Training Good content alone does not persuade When expertise, ideas or decisions fail to have the desired impact, the issue is often how they are communicated. We build presence and presentation skills so messages land clearly and people persuade their audiences.
04 Self-Leadership Stay clear-headed when demands pile up Heavy workloads, competing priorities and constant change challenge people every day. We strengthen self-leadership, reflection and resilience so employees and leaders can stay focused and take effective action under pressure.
05 Change & Transformation Change takes more than a plan New strategies, structures and processes work only when people understand and support them. We help teams and leaders provide direction, deal with uncertainty and put change into practice in everyday work.
06 Business Coaching Some challenges call for more than training New roles, difficult decisions and entrenched situations do not always have standard solutions. In confidential one-to-one coaching, specialists and leaders work through specific challenges and their next steps in development.

Understanding alone doesn’t change behaviour.

That’s why at yuii we don’t just talk about leadership, communication or conflict – we practise it. In a safe environment, participants work on real situations from their day-to-day work, try out new approaches, experience their own impact and receive precise feedback. Step by step, knowledge turns into new behaviour.

01

Real situation

Whenever possible, we train using participants’ own cases and situations they genuinely encounter in their working lives.

02

Try it out

Don’t just talk about models, methods and mindset: experience the difference they make.

03

Feedback & Re-Run

Precise feedback – often using video – followed by another go straight away. That is how real development happens.

04

Transfer

We offer follow-ups, peer-group sessions between modules and individual coaching to help embed learning in everyday work.

What remains when the training is over?

Good training does more than feel good in the moment. It changes how people lead, communicate and collaborate afterwards. Three examples from our work.

Leadership Development · KOSTAL Group

From emerging talent to confident leader.

Challenge: Future leaders should not have to figure out leadership only after stepping into the role. KOSTAL wanted to prepare them early for the situations they would genuinely face as leaders.

yuii solution: Five intensive training days in which future leaders do more than learn about leadership – they practise it: using realistic situations, personal feedback and plenty of space to develop their own leadership style.

Impact: KOSTAL has worked with yuii to develop its emerging leaders since 2019. According to KOSTAL, the Leadership Camp consistently receives exceptionally positive feedback.

Feedback Culture · Aperto / IBM iX

Don’t just explain feedback – practise it.

Challenge: The aim was to strengthen a positive feedback culture across the entire organisation – from trainees to executives.

yuii solution: Compact virtual learning sessions combining theory, a feedforward approach and hands-on practice using real cases from everyday work.

Impact: Participants were able to practise giving feedback immediately, receive individual feedback from the trainers and reflect together on what they had learned.
View case study
Self-Reflection · NEW WORK SE

Make self-reflection a skill people can truly experience.

Challenge: Employees were to reflect more effectively on their own behaviour, recognise their strengths and become more aware of key areas for development.

yuii solution: Two intensive training days that make self-reflection tangible rather than abstract: using coaching elements, video feedback and Applied Improvisation, participants experience their own impact, recognise patterns and work specifically on their personal development areas.

Impact: More than 90% of participants recommended the training internally; yuii has worked with NEW WORK SE since 2014.
