This person would be called upon when, say, a potential partner or client is still doubtful and having a difficult time making a decision. The specialist is paid to find just the right words, arguments, and tone, and has enough natural charm, to persuade them.

The word persuader has a number of meanings and tons of ambiguous connotations.

In the situation you are describing, the person is called a Closer.

From Dictionary.com a closer is:

a person or thing that closes

Which isn't terribly helpful at all, until we look for the correct disambiguation of Close:

to arrange the final details of; to conclude negotiations about


to complete or settle (a contract or transaction); consummate:

These definitions are probably the best fit for the term "Close" in the context provided.

Could also be a lobbyist, or if talking about a group of lobbyists just a lobby. Also from Dictionary.com:

a person who tries to influence legislation on behalf of a special interest; a member of a lobby


Especially in business, this person is often called a closer.

Closer: A person who is skilled at bringing a business transaction to a satisfactory conclusion.

Example: Harvey Specter in the TV series Suits is called the best closer in New York because of his ability to come to agreements with his clients.

    With his clients, or with the clients of opposing counsel? He doesn't like to go to court; I had taken "closer" here to mean he always settles, and does so in ways favourable for his client.

I would suggest negotiator

A person who has formal discussions with someone else in order to reach an agreement, or a person whose job is to do this


Not exactly what you are looking for but a closer word is Evangelist, meaning a zealous advocate of something.

It was earlier associated with people who seek others to convert to Christianity by preaching.

Nowadays we have the Technical or Technology Evangelists. From the page about it on Wikipedia:

A technology evangelist is a person who builds a critical mass of support for a given technology and then establishes it as a technical standard in a market that is subject to network effects.

    The primary meaning in my experience is still the conversion to Christianity one.

It depends on the context of the situation.

Negotiator is probably the closest general word in common usage for what you are describing. That, however, carries implications that the final result will be some sort of deal and that there may be some give and take. That would not be the ideal word without those connotations.

You have essentially provided the job description for a Lawyer, but that word implies there will be some interaction with legal institutions or other lawyers. It may also imply that the person being referenced has a license, depending on the jurisdiction being discussed.

A Lobbyist will perform those functions, but that term is almost exclusively used in connection with politicians or similar bureaucracies.

A Consultant may play a similar role. Normally, a consultant will be brought in to help determine the best course of action rather than to persuade a person that a previously chosen course was correct. However, the end result may be the same.

Another answer suggested Influencer. I agree with this, but influencer is a relatively informal term and also one that carries connotations of influencing large groups of people. I have never yet heard of an influencer being brought in to target a specific individual.

Closer was also suggested. Again, I agree but this is also a fairly informal term that carries some significant connotations. In the contexts I am familiar with, Closers are usually involved in sealing a deal and the word would sound odd used in a context that was not expected to end with a contract or transaction.

Rhetor or (with credit to Ooker) rhetorician also come close in their literal meanings. The words refer to someone who is an expert in rhetoric which is essentially the art of persuasion. However, those words are not in common usage and many native English speakers may be unfamiliar with them. They now mostly comes up in discussing historical teachers of rhetoric which was common in some time periods of Ancient Greece and Ancient Rome.

(With Credit to Brian Drummond) Evangelist has a similar meaning. Originally, it was used almost exclusively in religious contexts, but the meaning has been broadening. It comes up often in technology now. However, like influencer and some of the others, evangelism is more often associated with trying to sway large numbers of people rather than trying to persuade a specific individual.

Advocate refers to someone who presses a specific position and comes very close to your description. However, advocate is sometimes used a synonym for lawyer (along with many others including counselor, attorney, barrister, etc.) When it is not being used in the sense of being a synonym for attorney it does not necessarily carry an implication of skill or training the way that negotiator, lobbyist, and consultant do.

  • 2
    Perhaps it's more common to use rhetorician than rhetor. The academic field rhetorics usually goes along with composition (writing) to become rhetorics and composition. Freshmen in colleges are usually taught this to construct concrete arguments.

His (or her) job is specifically as you describe, with politicians as the intended target.

Almost all the suggested answers relate to business deals: a dealmaker, a negotiator, a closer (this last carrying the implication of closing the deal). Doesn't strike me as answering the question that was actually asked.

In the UK, a specialist who is hired to convince people (really, I ought to say the people), who might once have been called a politician, is these days more commonly known as a spin doctor.

When your job is to convince, you are talking about selling an idea, in the way that an ad man might try to sell a new product. Convincing people of something is very, very different from closing the deal. It is about convincing people to want to buy (something), not about negotiating the terms of the deal, and definitely not merely about getting the buyer's signature to close the deal.

In the advertising business, the ad agency's job used to be to convince the public to want to buy their client's product. In politics, the politician's job used to be to convince the public to want to "buy" their party's policies. Selling the people on the product - that was the concept.

So an ad agency's executive was called an ad man, but the more modern term, usual in politics in England, was spin-doctor, the man who puts a positive spin on all political news: i.e. construes everything in the best possible light.

His job is to convince people that the party is doing a good job, and thereby to convince them of the soundness of its policies, and hence to convince them to vote for it.


If it is a job, that would be a "spokesperson". They do it on behalf of someone else.

If it is a self-motivated activity it would be an "advocate".

The obvious avocation is public relations (PR). The trouble, of course, lies in the word public. Only the very wealthy individuals can afford such specialists.

When it comes to private or personal disputes, there is the role of ‘mediator’. These can even have a formal role in disputes over separation and divorce. But the role of the mediator is one of neutrality between two parties, rather than partisan support or advocacy for one individual.

There is an art of persuasion. It is called ‘rhetoric’. In Western history, this art of persuasion back to the 5th century BCE, when travelling experts in the art of persuasion offered to teach the art of persuasion.

It came to prominence in Athens, where the radical democracy (of law courts as well as political assembly) left the well born and affluent without any source of power other than popular assent.

This seems to have contributed to the popularity of a number of philosophers/teachers, claiming, among other things, to teach the art of persuasion, which for some amounted to convincing people to see proposed actions to be in their own interest. They came to be known as ‘sophists’, from which we derive the pejorative word sophistry, or the use of crafty arguments to manoeuvre people into agreeing to what we want.

I very much fear that any word that becomes associated with successful persuasion, however sweet, will sooner or later be tarred with a similar brush.

If you want the position to have a bit more sinister feel to it, I would go with 'fixer' or 'mechanic', implying a bit of hit-man action, like "an offer you can't refuse".


Some alternatives with a more negative connotation: if he’s paid to say things that aren’t true, he’s a bullshitter or bullshit artist. (This might be Bowdlerized to BSer or BS artist.) If he’s a true believer in a cause and promotes it no matter what, he’s an advocate or activist. If they’re annoying about it, fanatic. If he’s doing it for a political party, he’s a spin artist or perhaps spinmeister. Apologist originally meant a type of religious evangelists who studied other religious traditions, but has come to mean defending the indefensible. A disparaging slang term for someone paid to defend anything their employer does is a flack or PR flack. Someone who writes advertisements (especially if they’re insincere, poorly-argued or unoriginal) is a hack. A lawyer who’ll say anything to win a case is a shyster.

This doesn't actually have anything to do with closing a business deal or reeling in a doubtful customer but I think you're looking for The Mentalist, from the show... The Mentalist.

In the show, and in real life, mentalists can perform extraordinary feats of mind. They're not actually doing magic or even performing magic tricks though, so they don't necessarily need tools. You can think of a kind of Sherlock Holmes but also with excellent social and people manipulation skills.

Mentalist has many meanings in the dictionaries I've looked at but I think this quote from yourdictionary.com summarizes the dictionary meaning pretty well:

mentalist is a mind reader or magic person who can perform extraordinary tricks that rely on mental powers.

But wait! This part from wikipedia.com is actually, in my opinion, a much better explanation:

Mentalists generally do not mix "standard" magic tricks with their mental feats. Doing so associates mentalism too closely with the theatrical trickery employed by stage magicians. Many mentalists claim not to be magicians at all, arguing that it is a different art form altogether. The argument is that mentalism invokes belief and when presented properly, is offered as being "real" be it a claim of psychic ability, or proof that supports other claims such as a photographic memory, being a "human calculator", the power of suggestion, NLP, etc. Mentalism plays on the senses and a spectator's perception of tricks.

I understand this is an out of the box idea but I really like this word instead of the other suggestions like "influencer" or "closer", so I just wanted to bring this one to attention.

A good salesperson doesn't sell the product they sell the person. They find common ground, find what their target cares about and then they work it until they get it.
