NICOLAS AUBERT: So what brought me to Willis? That was about the opportunity to join a fantastic firm having a huge legacy and to drive the global center of expertise, which is London-based. So a great opportunity for me.

This merger is a fantastic opportunity for us to build a very unique company, building a company which is going to have a fantastic, very strong value proposition to our clients. So just by itself, this is the most exciting opportunity.

So growth is going to come from this merger. And growth is going to come from the fact that the value proposition that we are going to deliver to our clients is going to be unique. We will have an opportunity to engage with the C suite of our clients on both sides and reach each other, and really bring to our clients something which is one of the most important thing that they are looking for.

Think about that. Willis and Towers Watson are capable of bringing value proposition related to the people and value proposition related to risk management. Those two topics are part of the most important topics that any CEO is looking after.

So we will face some challenges during the merger. And one of them is just going to be knowing about each other, understanding each other’s value proposition, so that we are making sure that we deliver the whole value proposition to our clients. That’s the unique opportunity of this merger – being one integrated company facing the client, with the whole scope of the product and services. So understanding the overall value proposition’s going to be the most important challenge.

But we will overcome that by the fact that our people are going to be incredibly excited about that. This is a huge opportunity for them to learn about other types of businesses. That’s going to enrich them and give them developmental opportunities. So I’m quite sure that we will figure this out.

I really believe that our people are going to be very excited by the merger. Actually, they are already. And we see that day to day, because they want to engage, they want to be part of the story.


What is going to be very exciting for them, I think, is about having an even stronger value proposition to our clients. Are employees are incredibly, genuinely client-focused. So being in a situation where they are going to be capable of delivering even more, it’s going to be very rich for them.

So as a leader, I’m a very direct, simple person, very transparent, very much to the point. And I’m very enthusiastic. So I’m incredibly positive about things. I like when there is dynamic, when there is energy. So people are going to expect that from me, I hope.

What makes me laugh? What makes me laugh would be kind of paradoxical situations. When people feel that they are off track, but in fact, they are doing something which is funny from the other’s perspective. So some things which are kind of out of the normal – that’s quite funny for me.

Meet the Proposed Leadership Video

JULIE GEBAUER: Hi. My name’s Julie Gebauer. And I’m from Darien, Connecticut, although if you want to know where I work, I work in Stamford, Connecticut, or anyplace around the world.

What drew me to Towers Watson many years ago was the opportunity to learn and grow. And expectations were well exceeded. Every day, I’ve had the opportunity to grow and apply my skills in a broader way— not just delivering on my dream of becoming a pension actuary. And it’s that, along with the really interesting, talented, and caring people that have kept me here for 29 years.

There are so many reasons I’m excited about this merger. Really, at its core, though, is that these two organizations, which are so strong on their own, are going to come together and deliver something that’s bigger, with greater impact, than they could have done on their own.

I also think specifically in the area of human capital and benefits, that we’ll have great opportunities to deliver on things related to human resources, to really rethinking the employee experience, from selection and onboarding to choices that people are making about health care and retirement. And there, too, we’ll have this great opportunity to not just provide advice, but help companies implement solutions, whether it’s placing insurance or implementing software.

So as with almost any merger integration, there will be challenges. There’s no denying that fact. One of the biggest ones will be the tendency to want to turn inwards. And we just have to keep in mind that the reason we’re in business is to help organizations and the employees of those organizations, and keep ourselves focused outward, helping those organizations, and fending off the competition.

I think people should be really excited about the opportunity to bring this expanded portfolio of services to our clients and to work with a whole new set of really great people. I think the combination is going to present great opportunities for all of us.

There are a few things that people should know about me as a leader. The first one is that I practice fanatic discipline. What does that mean? That means that I really abide by the standards that we set for ourselves around the principles around which we operate, the values on which we’re formed. I think it’s really important to stick to those without fail.

So what would I admit that people wouldn’t normally know and that I might be a little bit embarrassed about? I never walk by a lucky penny. I’ll walk by another coin, a dollar bill, a euro, but not a lucky penny, because for some reason, since I was a child, I felt that lucky penny, when I put it in my pocket, just gives me a little bit of extra confidence.

What makes me laugh? What makes me laugh? When I make a goofy mistake, it makes me laugh. My kids make me laugh. My husband makes me laugh. My team makes me laugh.
