Notes

What is a sparring partner for personal and business questions?

A sparring partner is an outsider with no mandate, method, commission or stake in your outcome, who tests your assumptions and tells you what he sees. The term comes from boxing: you think aloud, he pushes back, and you decide. Winn Chelini is that person: an independent sparring partner in Zürich, on the Gold Coast and in Zug.

Where does the term come from, and why does the boxing image only half fit?

In boxing, the sparring partner is the person you train with. He hits back; otherwise the training would be worthless. But he is not trying to win the fight. He wants you to be better on the day it counts. That part of the image holds: resistance without rivalry. Someone pushes back so that your thinking holds up when it matters.

The other part does not fit. Boxing is about force and speed. A conversation about whether to hand over the company, or whether to stay in a marriage that has gone quiet, needs neither. It needs precision: the question you are not asking yourself, and the objection nobody around you voices any more. A sparring partner does not hit back. He tells you what he sees and explains why. Then you decide.

In Switzerland, Germany and Scandinavia the word is common in business: consultants, fiduciaries (Treuhänder) and board members like to call themselves a “Sparringspartner” to an owner or a family. To an English ear it can sound odd outside the ring; the section below explains why.

What does a sparring partner actually do?

Three things, in this order.

He listens until he has understood your situation. Not just the figures and the people involved, but also what you leave out or say twice. Often things start to sort themselves while you talk, because it is the first time you have said them in full sentences to someone who gains nothing from them.

He tests your assumptions. “Head office will not let me stay if I turn this role down.” Is that written anywhere, or is it what you expect? “My co-founder would never agree to an exit.” Have you asked him, or do you know because you have worked together for twelve years? “My wife would never agree to sell the house.” Has she said so, or have you stopped asking? Many decisions rest on two or three sentences like these that nobody checks any more because they have been true for so long.

He tells you what he sees. Even when it is not what you wanted to hear, and even when it contradicts your advisers. That is where the role differs from the others at the table. A consultant recommends and delivers a concept. A coach works with a method and often withholds his own opinion on principle. A mentor shows you the path he took. A board member carries interests and liability. A sparring partner has none of these: no mandate that depends on your decision, no method you have to learn first, no commission if you sell, buy or stay. The roles in detail are compared in Sparring partner, coach, mentor or consultant: what is the difference?.

An example. A country manager in Baar, two years into a Swiss posting, is offered the regional role in Singapore. Her employer explains the package, the relocation agency the move, her lawyer the contract. The sparring partner asks whether she wants to go, what her partner would say if she asked him properly, and what she would be giving up in Zug that she has only just built. That question is in nobody’s mandate, and it is the one that decides.

Which private decisions is sparring for?

The line between business and private is rarely sharp in practice. Handing over a company also means handing over thirty years of daily structure. An argument with a sister about the parents’ house in Küsnacht ZH is rarely only about the house. Anyone wondering whether to go home after five years in Switzerland is rarely the only person in the household with a view.

The private questions people bring to sparring are often these: stay or leave, in a marriage, in a firm, in a country. Whom you can still trust when your bank, your lawyer and your family all have an interest. How to talk to adult children about money without it costing you the relationship. What comes after retirement, when nobody calls on Monday morning. For international residents in Zug and Zürich there is an extra layer: the people you would normally think with are in another time zone, and the conventions you are deciding within are not the ones you grew up with.

The same rules apply as in business: it is about a decision or a conflict, you are able to act, and you want to decide for yourself. What sparring is not: couples therapy, mediation, legal or inheritance advice. I work with one person, not with both sides of a dispute; a joint conversation needs a mediator or a couples counsellor. Often the order helps: first get clear on your own about what you want to say, then have the conversation with the others.

Is “sparring partner” even an English business term?

Not quite yet. In English, “sparring partner” is first a boxing term. In business it is a calque, a loan translation from German and Scandinavian usage, and it is becoming established slowly. There is no exact English equivalent; the nearest idea is the devil’s advocate, who pushes back on principle, whether he believes it or not. A sparring partner pushes back only when he means it, and says so when he agrees.

In German the dictionary form is “Sparringspartner” with a linking s; “Sparringpartner” without it is also common in Switzerland. I use “sparring” in English because it names honest push-back, and because it is the word people around you in Switzerland already use.

English matters here more than elsewhere. In Canton Zug, 14.1 per cent of residents aged 15 and over named English as a main language in 2022, the highest share of any canton. Some of them carry responsibility in companies and families and have nobody nearby who owes them an honest, independent view in their own language.

Who is sparring not for?

People in an acute crisis. Sparring assumes that you are fundamentally healthy and able to act. If you have not slept properly for weeks, see no way forward, or have thoughts of harming yourself, the right people to call are your GP, a psychotherapist or the Dargebotene Hand, the Swiss listening helpline, on 143, not me. I do not diagnose and I do not treat; how sparring differs from psychotherapy is set out in the questions on the offer. If it becomes clear that you need a specialist, I will say so openly and help you find one, in English if you prefer.

People who want to buy an answer. An expert report, a company valuation, a tax strategy or an investment recommendation come from the licensed professionals for that. I am glad to help you put your questions to them in order first; the answers are theirs to give.

People who want confirmation. If the decision is made and you need someone to approve of it, you will hear more questions from me than agreement. That is not a lack of respect; it is the point of the exercise.

And people who want a programme. Sparring has no modules, no homework and no process over twelve sessions. Often a single conversation is enough; whether a second follows is your call afterwards. If you want to work on a pattern in your own behaviour over several months, coaching is the better fit.

How does a sparring session with Chelini work?

It starts with a free, confidential conversation of 20 minutes, by phone or video. You outline your topic, I tell you whether I am the right person, and we agree place, time and format. There is nothing to prepare.

The session itself lasts 60 minutes; 90 minutes are available on request. I come to you, and travel is included anywhere within 60 minutes’ drive of Wetzikon, from the city of Zürich and Winterthur over the Gold Coast to Zug, Rapperswil and Einsiedeln. On site means at your home, at your office, at a quiet place of your choice, or walking by the lake or in the woods. You do not enter a practice, and nobody sees you enter one. Why I come to you rather than the other way round is explained in Home and office visits: a sparring partner who comes to you. Online, a session also lasts 60 minutes. Ongoing sparring over three months is possible; it is not a condition. You pay per session, no subscription, no package. The fee is fixed and depends on the format and the length of the conversation, never on who you are. I tell you what it is in the confidential conversation – before the first session, not after. No VAT is added. What other providers in Switzerland charge is in How much does a sparring partner cost in Switzerland?

By arrangement: mostly in the evening, on Mondays also during the day, and on Saturdays and Sundays. We speak English, German or a mix, whichever lets you say precisely what you mean.

On confidentiality: I commit in writing to confidentiality, including the fact that we know each other. I record nothing; brief notes are destroyed no later than 12 months after we finish. I do not have professional secrecy in the way doctors and lawyers do, and I do not promise it. The commitment has three limits: a legally binding order from a court or authority, an acute danger to life and limb, and a child’s welfare. What Swiss law provides is explained in Is coaching confidential in Switzerland? What the law says.

In the session itself, you talk, I ask, test assumptions and tell you what I see, including from the uncomfortable angle. I bring no industry expertise to that, but years in engineering and IT projects with many parties and conflicting interests: the habit of seeing quickly what does not fit. At the end we note what has become clearer and what you will do next. With a deadline, a great deal can be sorted in one session; how that works is described in A decision under time pressure: why one conversation is often enough.

In short

A sparring partner is an independent person with no stake in your outcome who tests your assumptions and tells you what he sees. That works for business and for private decisions alike, as long as you are able to act and want to decide for yourself. A session lasts 60 minutes, at your place or online; the fee depends on the format and the length, and I tell you what it is in the first, confidential conversation, before you decide.

If you would like to think this question through with someone who has no stake in it: Winn Chelini, independent confidant and sparring partner in Zürich, on the Gold Coast and in Zug. The first step is a confidential conversation – 20 minutes, by phone or video, free and with no follow-up from my side.

Short answers

Questions on this topic

Can a friend or my spouse be my sparring partner?

For many things, yes. The difference is the stake: your spouse lives with your decision, your friend wants to keep the friendship intact. Both hold back at a certain point. A sparring partner has no such point; he can say what he sees because it costs him nothing either way.

Will a sparring partner tell me what to do?

No. He tells you what he sees and gives his reasons; that can be a clear opinion. He does not take the decision for you and does not take it off your hands. A session ends with a next step that you set – even if that step is to do nothing for now, deliberately.

Is a sparring partner the same as a devil's advocate?

Close, but not the same. A devil's advocate argues the opposite side on principle, whether he believes it or not. A sparring partner tests the assumptions your decision rests on and tells you honestly where he agrees and where he does not. Sometimes that means taking the other side; sometimes it means confirming that you have thought it through.
