01 Global Reach

The right people, wherever they are.

We want the freedom to work with people we trust, bring together the right mind across disciplines and remain open to ideas that do not fit the traditional model.

That means working closely with colleagues across our global network, as well as other trusted firms where this best serves the client.

02 Our Story

We want to be closer.

We want to be close enough to hear the story behind the question.

To understand what matters to the business and the people inside it, and to spend time building the relationship because not every conversation needs to be measured by what can be billed.

So we offer another option: a senior, practical team that multinational businesses can turn to, with the freedom to bring together the right minds across disciplines.

We believe good work is built on closeness, openness and clear communication: with the client, with the people doing the work, and with the society we are all part of.

That is why we built SCS Collective.

To do good work, with good people, for something larger than ourselves.

Our mark takes its cue from the Japanese character 人: two people supporting one another.
The space around them represents the wider society we are all part of.

Good for the client. Good for the people doing the work. Good for society (our take on sanpō yoshi).

05 The Journal

Practical thoughts from the Collective.

We write about business, tax and the questions that come up when companies work across markets and cultures.

Some pieces are practical. Some come from conversations with clients or things we are seeing in the market. Mostly, we share what we are learning and what we think may be useful to others.
